DAVID KUNZE CASE: PART TWO; THE WASHINGTON COURT OF APPEALS REJECTS CORNELIS VAN DER VUGTS EARPRINT TESTIMONY;



"HE (CORNELIS VAN DER VUGT) HAD BEEN TO COURT IN SIX EARPRINT CASES, ALL IN HOLLAND, AND THE JUDGES IN THOSE CASES HAD NOT BEEN CONCERNED ABOUT HIS METHODOLOGY; INDEED, THEY HAD “ACCEPTED THAT YOU CAN IDENTIFY AN INDIVIDUAL BY HIS EARPRINT.” HE DID NOT PRESENT OR REFER TO ANY PUBLISHED LITERATURE STATING THAT EARPRINT IDENTIFICATION WAS GENERALLY ACCEPTED IN THE SCIENTIFIC COMMUNITY;"

MORGAN J. FOR THE UNANIMOUS WASHINGTON COURT OF APPEALS;
(State v. Kunze, 1999 WL 1017935 (Wash. App. 1999));

-------------------------------------------------------------------------------

"David Wayne Kunze appeals his convictions for aggravated murder and other crimes," the appeal court's decision begins;

"The principal issue is whether the State's witnesses could opine, based on the relationship among some of the anatomical features of the external ear, that Kunze was the probable and likely source of a latent earprint discovered at the scene," the decision continues;

"Other issues are whether two police officers could opine that the crime scene might have been staged to look like a burglary, and whether the trial court properly restricted the cross-examination of a jailhouse informant. We reverse and remand for new trial.

In the early morning hours of December 16, 1994, an intruder entered the Clark County home of James McCann. McCann was asleep in the master bedroom. His son Tyler, age 13, was asleep in another bedroom. The intruder bludgeoned McCann in the head with a blunt object, causing his death. The intruder also bludgeoned Tyler in the head, causing a fractured skull. When the intruder left, Tyler crawled out to the front porch, where he was found after daylight by a passerby.

While awaiting surgery at the hospital, Tyler told the police that he had been afraid to look at his attacker closely. He thought, however, that the attacker was a darkly complected male, possibly Puerto Rican, about six feet tall with medium build, dark or black hair to mid-ear, 25 to 30 years of age, and a deep voice. Tyler later recalled that the attacker wore gloves but not glasses, and had a flashlight in his mouth. Kunze is in his mid-forties, wears glasses, and has reddish-blond hair.

Back at the house, the police observed that the intruder had opened drawers and cabinets without disturbing the contents. They also found that the intruder had taken a TV, a VCR, stereo speakers, a “boom box,” McCann's wallet containing identification and credit cards, McCann's truck, and various other items.

George Millar, a fingerprint technician with the Washington State Crime Laboratory, processed the home for evidence. He discovered a partial latent earprint on the hallway-side surface of McCann's bedroom door. He “dusted” the print by applying black fingerprint powder with a fiberglass brush. He “lifted” the print by applying palm-print tape first to the door and then to a palm-print card. The resulting print showed the antitragus and portions of the tragus, helix, helix rim, and antihelix. The external features of a complete ear are shown in the following diagram.

The police were immediately interested in Kunze, notwithstanding Tyler's description of the intruder. Kunze had been married to Diana James from 1976 to April 1994. On December 12, 1994, four days before the intruder entered McCann's home, James told Kunze that she and McCann were planning to be married. Kunze was upset by the news, according to his own later statement.

The police interviewed Kunze several times. They also searched, with his consent, his truck, house, boat, storage locker, and safety deposit box. The searches did not disclose anything significant, with the possible exception of a receipt for a flashlight.

On or about March 28, 1995, Michael Grubb, a criminologist with the Washington State Crime Laboratory, compared the latent print from McCann's bedroom door with photos of the left side of Kunze's face. He concluded that the latent print “could have been made by Dave Kunze.” He also thought that “[i]t may be possible to obtain additional information by comparing the [latent print] to exemplar impressions.”

On September 21, 1995, Millar and Grubb met with Kunze to obtain earprint exemplars. Neither had taken an earprint exemplar before, although each had practiced on laboratory staff in preparation for meeting with Kunze. For each of the seven exemplars they took, they had Kunze put hand lotion on his ear and press the ear against a glass surface with a different degree of pressure (“light,” “medium,” or “hard”). They then dusted the glass with fingerprint powder and used palm-print tape to transfer the resulting impression onto a transparent plastic overlay.

The reason Millar and Grubb took multiple exemplars is that they were consciously trying to produce one that would match (i.e., “duplicate” the latent print from McCann's door. They knew that earprints of the same ear vary according to the angle and rotation of the head, and also according to the degree of pressure with which the head is pressed against the receiving surface. They did not know the angle and rotation of the head that made the latent print, or the degree of pressure with which that head had been pressed against McCann's door. Hoping to compensate for these difficulties, they told Kunze to use a different degree of pressure each time (“light,” “medium” or “hard”), and they looked at the latent print as they worked.

After Millar and Grubb took the exemplars, they were asked to compare them to the latent print. Millar declined because his laboratory supervisor thought that earprint identification was “out of the expertise of the [crime lab's] latent unit.” Grubb went ahead, concluding that “David Kunze is a likely source for the earprint and cheekprint which were lifted from the outside of the bedroom door at the homicide scene.”

In June 1996, the State charged Kunze with aggravated murder, assault, robbery, burglary, and kidnapping. In October 1996, Kunze moved for “a pre- trial order excluding any evidence of earprint identification.” In December 1996, the trial court convened a Frye hearing at which Grubb and other witnesses were called. We must understand their testimony in detail in order to resolve the issues on appeal.

Grubb testified to extensive qualifications as a criminalist. He had been working as a criminalist for more than twenty years, and he was currently the manager of the state crime lab's Seattle office. Although he had never before dealt with earprints, he specialized in firearm and toolmark identification, and he had analyzed “impression evidence” of other kinds. He had not seen any data or studies on earprints, or on “how often an ear having the general shape of the questioned print in this case appears in the general human population;” he thought, however, that a Dutch policeman named Cor Van der Lugt might have such information. He had used transparent overlays to compare the latent and the exemplars in this case, and such overlays are a generally accepted method of making comparisons. When he compared the latent print with the exemplars taken from Kunze, he emphasized the exemplars taken with “a lighter amount of pressure,” because those “more closely approximated ... the impression from the crime scene.” He claimed that latent earprint identification is generally accepted in the scientific community, reasoning that “the earprint is just another form of impression evidence,” and that other “impression evidence is generally accepted in the scientific community.” He concluded that “Mr. Kunze could be the source of [the latent] impression, and even further, I believe it's likely that the impression from [the] crime scene is Mr. Kunze's ear and cheek print.”

Cor Van der Lugt testified to extensive qualifications as a police evidence technician. He had been a Dutch police officer since 1971 and a crime scene officer since 1979. He had trained other crime scene officers for many years. Being interested in the reliability of earprints, he had written “a lot of letters all around the world to people who did something with earprints, but unfortunately ... didn't get too much of [a] response.” He had adopted methods used by Professor Lunga of Germany, “who did [an] investigation as to what parts of the ear look alike between parents and their children;” methods used by Mr. Hirschi of Switzerland, who “did an investigation between the relation of the height of defining of an earprint and the body length of the offender;” and the methods used by several other people in the eastern part of Germany. He had received over 600 cases “for comparative analysis” and had made an identification to his own satisfaction in “somewhere between 200 and 250 cases.” On the basis of “somewhere between 100 and 200 prints,” he had concluded that pressure distortion is not a problem that prevents you from making an identification or a comparison between ears, even though you must “get the same pressure on the ear as the ear that was found on the scene of a crime;” the solution, he thought, was merely to take several exemplars under different degrees of pressure, then “pick the one that comes closest” to the latent print. He had been to court in six earprint cases, all in Holland, and the judges in those cases had not been concerned about his methodology; indeed, they had “accepted that you can identify an individual by his earprint.” He did not present or refer to any published literature stating that earprint identification was generally accepted in the scientific community. He did, however, testify as follows:

Q: [D]o you have an opinion as to whether ... the uniqueness of the human ear as a basis for personal identification is a notion that is generally accepted in the Netherlands and elsewhere amongst those engaged in forensic identification?
A: It is accepted, yes.

Alfred V. Iannarelli testified to extensive qualifications as a law enforcement officer. For 30 years, he had worked as a deputy sheriff in Alameda County, California, as the chief of campus police at California State University at Hayward, and in several other law enforcement positions. Thereafter, he had worked as a consultant on ear identification. He became interested in ears in 1948, and over the next 14 years classified perhaps 7,000 ears from photographs (but not from latent prints). In 1964, he published a book describing his system, which he calls “earology” or the “science of ear identification.” In 1989, he published a second edition through a different publisher. He had been prohibited from testifying in a 1985 Florida case called State v. Polite on the ground that his system of ear identification was not generally accepted in the scientific community. He had testified without objection in a 1984 California murder case called People v. Anzillotti. He did not know of any published scientific studies confirming his theory that individuals can be identified using earprints, and he did not claim that his system was generally accepted in the scientific community. On the contrary, he testified:

Q: Are you aware of any scientific research at all that would confirm your theory that ears are so unique that individuals can be positively identified by comparing known earprints with latent ear impressions?
A. Ear photographs, not earprints. Counsel, this is relatively a new science.

His personal belief was that human ears are sufficiently unique to support a positive identification in an appropriate case, and that the latent print left on McCann's door “matche[d] exactly” the exemplars taken from Kunze.

The 1989 edition of Iannarelli's book was introduced along with his oral testimony. Titled “Ear Identification,” it is published by the Paramont Publishing Company of Fremont, California. It contains no bibliography and no scientific verification.

Dr. Ellis Kerley testified to extensive qualifications as a physical anthropologist. He has a doctorate in anthropology from the University of Michigan and was for many years a professor of that subject. He has taught the anatomy of the human ear. He formerly was President of the American Academy of Forensic Sciences, and President and First Diplomate of the American Board of Forensic Anthropology. He has worked on cases such as the assassination of President John F. Kennedy. He thought that the human ear is probably different for each person, but he had “no information” indicating whether one ear can be differentiated from another by observing the ear's gross external anatomy. He did not “consider Mr. Iannarelli's work scientific;” on the contrary, it was “narrative,” not “reported in a scientific manner,” and “not subjected to any statistical analysis.” He rejected Van der Lugt's approach of “apply[ing] pressure until you can make the [exemplar] prints look about the same” as the latent print in issue; as he put it, “we don't do that in science ... [b]ecause we're not trying to make them look alike.” He stated that earprint identification “has not been presented in generally scientific sessions or publications,” and that he was not “aware of any scientific research or authoritative literature ... concerning earprint identification[.]” It was his opinion that earprint identification has not achieved “general acceptance” in the forensic science community.
Professor Andre Moenssens testified to extensive qualifications as a fingerprint examiner and law professor. He began his career as a criminalist in Belgium. He holds a J.D., and an LL.M. in scientific evidence. He teaches scientific evidence and has published numerous books on that subject. He testified in part:

Q: [D]o you have an opinion whether or not earprint identification is generally accepted as reliable in the forensic science community?
A: [T]he forensic sciences ... do not recognize as a separate discipline the identification of ear impressions. There are some people in the forensic science community, the broader forensic science community, who feel that it can be done. But if we are talking about a general acceptance by scientists, there is no such general acceptance.
Q: Is there any evidence that earprint identification has ever been tested by scientific methodology?
A: To my knowledge, it has not been.
Q: Or adequately subjected to scientific peer review?
A: If by peer review, you mean inquiry and verification and studies to confirm or deny the existence of the underlying premise, that is, ear uniqueness, to my knowledge that has not been done.
...
Q: With respect to earprint identification, has it ever been shown that results can be reliably obtained in terms of an acceptable rate of error?
A: To my knowledge, there has been no investigation in the possible rate of error that comparisons between known and unknown ear samples might produce.

While he agreed that one earprint can always be compared with another, he noted that “[t]he question is whether that comparison means anything.” He did not know of any generally accepted methods for recording ear characteristics or determining the significance of a “match.”

George Bonebrake testified to extensive qualifications as a latent fingerprint examiner. He worked for the FBI from 1941 to 1978, when he retired and became a private fingerprint consultant. During his last three years with the FBI, he was in charge of its latent print section, supervising 100 examiners and 65 support people. He never identified anyone based on earprints, and to his knowledge no one else at the FBI did either. He testified:

Q: Is there anything in the materials that you have read that indicates earprint identification has been generally accepted in the forensic science community?
A: No, sir.
Q: What is your impression of the state of earprint identification at this point in forensic science history?
A: That there have been a few cases of individuals making earprint comparisons and identifications, but I'm not aware of any study or research that would indicate to me the uniqueness of earprints when it comes to the comparison of [known] earprint impressions ... with the latent earprint impressions; that's based on class characteristics.
...
Q: Does the literature indicate that there are problems in attempting to obtain earprint exemplars?
A: Especially when it comes to pressure, yes, sir.
...
Q: Have you ever seen any authoritative text published in any discipline of forensic science that's gone on record claiming that earprint identification is generally accepted in the forensic science community?
A: No, sir.

In his professional opinion, the latent print from McCann's door “is of poor quality,” shows only class characteristics, and shows nothing unique.

Tommy Moorefield testified that he was a fingerprint specialist with the FBI in Washington, D.C. He had worked for the FBI for 36 years as of December 1996. He had conducted advanced latent fingerprint courses throughout the United States, instructed new agents on collecting and preserving evidence, and worked on both the Waco disaster and the TWA Flight 800 disaster. He had once made an identification from a lip print, but he had never made an identification from an earprint. He was “not real sure” that ear print identification is generally accepted in the community of forensic scientists, and he was unaware of the FBI collecting any data on earprints.

William Stokes testified that he was a special agent and chief of all photographic operations for the FBI in Washington, D.C. He had identified individuals from photographs of their ears, but not from latent earprints. He had “no knowledge” of whether latent earprint identification is generally accepted by the scientific community.

Ralph Turbyfill testified that he is the long-time chief latent fingerprint examiner for the Arkansas State Crime Laboratory. He was able to identify a person from an earprint in one case, because of hair follicles that were peculiarly located. He had tried, unsuccessfully, to identify people from earprints in two other cases. He did not believe that earprint identification is generally accepted in the forensic science community, and he did not know of any publication or treatise that so claims.

Gary Siebenthal testified that he had been an officer with the Peoria, Illinois, police department for 23 years and a crime scene technician for 20 of those years. Although he had identified a defendant from an earprint on one occasion, he did not know of anyone who had “proclaim[ed] that earprint identification is generally accepted as reliable in the forensic science community.” Nor did he know of any scientific research on reliable techniques for making earprints or dealing with pressure distortion.

Paul Norkus was a long-time latent print analyst from Pensacola, Florida. He had been involved in the 1985 case, State v. Polite, in which Iannarelli had also been involved. Although he and Iannarelli thought they had made an earprint identification in that case, the trial court ruled that earprint identification was not generally accepted in the scientific community; thus, they were not allowed to testify. He did not believe that the FBI classifies or even keeps a file of earprints, and he had no “idea how often a given general ear shape occurs in the general population.” Except possibly for a 1949 article by a Russian author, he did not know of any publications stating “that earprint identification is generally accepted in the forensic science community[.]”

Ernest Hamm testified that he had been a crime laboratory analyst-supervisor in Jacksonville, Florida, for approximately 16 years. He had made an earprint identification in one case. He had been able to do that because the defendant “had a very peculiar mark in the lobe area of the ear.” Although he personally believed that earprints can be identified, he knew of nothing to indicate that earprint identification is generally accepted in the forensic science community.
William Sherlock testified that he had worked in law enforcement for more than 30 years. In part, he had trained others to identify tool marks. He had been involved in several earprint cases, but none had gone to trial and he had never testified on earprint identification. “The limited amount of people [he had] talked to ... don't really have an opinion” on whether earprint evidence is generally accepted as reliable in the forensic science community.

John Olenik testified that he had worked for the Ohio Bureau of Criminal Identification and Investigation for 27 years before starting his own business. He was a past president of the Ohio Identification Officers' Association and had published several articles. He had been involved in two earprint cases, neither of which had gone to trial, so he had never testified on earprints. Although he personally believed that earprints could be reliably compared, he did not know of any publications stating that earprint identification is generally accepted in the scientific community.

Roy Gourley testified that he was a detective from Sonoma County, California. Like Iannarelli, he had worked on the 1984 murder case of People v. Anzillotti. Because an earprint had been found in that case, he sought information on earprints from the FBI's latent print section in Washington D.C. He was told that the FBI had no experience with earprints and that he should contact Iannarelli. Iannarelli compared the latent print, found that it was the defendant's, and testified as a witness at trial--without objection from the defense. Gourley was not asked whether earprint identification evidence is generally accepted in the scientific community.

At the end of the hearing, the trial court entered written findings of fact and conclusions of law. It concluded that “the principle ... known as ‘individualization’ through the use of transparent overlay, applied to the comparison of the latent impression in the present case with the known standards of the defendant, is based upon principles and methods which are sufficiently established to have gained general acceptance in the relevant scientific community.” As a result, it admitted the earprint evidence.

Trial commenced on June 25, 1997. The State called Grubb and Van der Lugt, but not Iannarelli, to compare the latent print to the exemplars and to opine about the significance of the comparison. Grubb testified that the latent print showed “the antihelix, the interior portion of the ear; the helix rim, that is the top of the rim of the ear; tragus and antitragus, two portions of the ear down below;” that he had compared those anatomical features using transparencies; and that he had found “very good correspondence of those features.” He opined, to a reasonable degree of scientific certainty, that “Mr. Kunze's left ear and cheek [were] the likely source of this [ear print] impression at the [crime] scene.”

Van der Lugt testified that he also compared the latent earprint and the exemplars by using transparencies. He found “a few parts that correspond completely,” but also some “differences.” He believed that the differences were insignificant, because “[y]ou will never find ... a 100 percent fit” and “any dissimilarities” were caused “by pressure distortion.” Although he conceded that “no study has ever been published in the world that could tell the jury how much correspondence is actually required in order to declare a match,” he also opined:

Q: Mr. Van der Lugt, as a result of your comparison of the Grubb standards and your independent comparison of your own standards with the crime scene tracing earprint that was taken in this case, do you have an opinion as to the probability that the defendant's left ear is the source of the latent impression which was left at the scene of the crime in this case?
A: I do have an opinion, yes.
Q: What is your opinion, then?
A: I think it's probable that it's the defendant's ear is the one that was found on the scene.
...
Q: [H]ow confident are you of the opinion that you just expressed?
A: I'm 100 percent confident with that opinion.

Kunze was convicted of aggravated murder, burglary and robbery. He was sentenced to life without possibility of parole on the murder conviction, and to standard range sentences on the other convictions. This appeal timely followed.


I.


The main question on appeal is whether Grubb and Van der Lugt could properly opine, based on the similarities and differences that they observed in the overlays, that Kunze was the likely or probable maker of the latent print. Kunze says they could not, because they were relying on scientific, technical or specialized knowledge not generally accepted in the relevant scientific, technical or specialized community. The State says they could, either because they were not relying on scientific, technical or specialized knowledge, or because they were relying on scientific, technical or specialized knowledge that was generally accepted in the relevant scientific, technical or specialized community. We inquire (A) whether Grubb and Van der Lugt were relying on scientific, technical or specialized knowledge, and (B), if so, whether that knowledge was generally accepted in the relevant scientific, technical or specialized community.


A.


Grubb's and Van der Lugt's testimony was in opinion form. An opinion is admissible only if it has a rational basis, which is the same as to say that the opinion must be based on knowledge. The knowledge may be personal, or it may be scientific, technical or specialized. So- called “lay” opinion is simply opinion based on personal knowledge (i.e., on knowledge derived from the witness' own perceptions, and from which a reasonable lay person could rationally infer the subject matter of the offered opinion). So-called “expert” opinion is simply opinion based in whole or in part on scientific, technical or specialized knowledge. At least in some instances, there is no meaningful distinction between scientific knowledge on the one hand and technical or specialized knowledge on the other.

To comprehend how these rules apply here, we must understand that forensic science differs fundamentally from other kinds of science. As one writer has put it, “[f]orensic identification science has selected for itself--or had thrust upon it--a project that is unknown to other fields: the unique identification or, more properly, individualization of various objects, including persons....” Accordingly: The goal of individualization contrasts with conventional science of virtually every kind. “Individualization is unique to forensic science.” Normal science is concerned with grouping objects and events into meaningful classes, discovering systematic relationships among these classes, and developing and testing theoretical explanations for those shared attributes and relationships. While normal science looks only between classes, forensic identification science ... looks within classes. While normal science is concerned with establishing regularities, forensic science is concerned with exploiting irregularities ....

Because of this atypical goal, forensic science is dependent on the existence and identification of individualizing characteristics, as opposed to class characteristics. An individualizing characteristic is one that shows an object to be unique, or, in alternative terms, one that distinguishes the object from all other objects; it “may be a single feature viewed alone, or an ensemble of features viewed in combination.” A class characteristic merely “separate[s] a group of objects from a universe of diverse objects.”

A forensic scientist must respect this difference between individualizing and class characteristics when opining about the maker of a latent print. On the basis of class characteristics alone, a forensic scientist can say that a suspect “cannot be excluded” as the maker of a latent print, that the suspect “could have made” a latent print, or that a latent print is “consistent with” exemplars. On the basis of individualizing characteristics--and only on the basis of individualizing characteristics--a forensic scientist can say that a suspect made or probably made a latent print.

Here, Grubb and Van der Lugt claimed that Kunze probably made the latent print taken from McCann's door. As a result, they were necessarily claiming that they had found, and were relying on, at least one individualizing characteristic.

According to the record, Grubb or Van der Lugt lacked personal knowledge of any individualizing characteristic. They could not have observed an individualizing characteristic like a scar, tear, mole, or abnormal hair follicle, because the overlays did not show any such feature. They were able to observe the antitragus, tragus, helix, helix rim, and antihelix, insofar as shown in the latent print, but each of those features was a class characteristic, not an individualizing one. They were able to observe the relationship between the antitragus, tragus, helix, helix rim, and antihelix, insofar as it was shown in the latent print, but a lay person using common knowledge would have had no idea whether such relationship was an individualizing characteristic; to conclude that it was, Grubb and Van der Lugt necessarily had to be employing scientific, technical or specialized knowledge. We turn, then, to whether that knowledge was generally accepted in the relevant community.


B.


Washington follows Frye. Frye provides that novel scientific, technical or other specialized knowledge may be admitted or relied upon only if generally accepted as reliable by the relevant scientific, technical or specialized community. General acceptance may be found from testimony that asserts it, [FN76] from articles and publications, from widespread use in the community, or from the holdings of other courts. General acceptance may not be found “[i]f there is a significant dispute between qualified experts as to the validity of scientific evidence.” When general acceptance is reasonably disputed, it must be shown, by a preponderance of the evidence, at a hearing held under ER 104(a). When general acceptance cannot be reasonably disputed, it may be judicially noticed in the same way as any other adjudicative fact. We review “de novo,” which means without deference.

In this case, twelve long-time members of the forensic science community stated or implied that latent earprint identification is not generally accepted in the forensic science community. Kerley, Moenssens, and Bonebrake expressly said it was not. Turbyfill said he believed it was not. Moorefield, Stokes, Siebenthal, Norkus, Hamm, Sherlock, and Olenik each testified to a lack of information or a lack of opinion--but if the forensic science community had generally accepted latent earprint identification, each of them surely would have known about it. Bonebrake, Moorefield, Stokes and Norkus testified that the FBI does not use latent earprint identification-- which the FBI would surely do if the forensic science community had generally accepted latent earprint identification. Even Iannarelli, perhaps the foremost American advocate of earprint identification, declined to assert that latent earprint identification has been generally accepted; he relied instead on his own personal belief.

Grubb asserted general acceptance, but not on tenable grounds. He reasoned, essentially, that latent earprints are a form of impression evidence; that other forms of impression evidence are generally accepted in the forensic science community; and thus that latent earprints must be generally accepted in the forensic science community. We reject his premise that latent earprints automatically have the same degree of acceptance and reliability as fingerprints, toolmarks, ballistics, handwriting, and other diverse forms of impression evidence.

Like Iannarelli, Van der Lugt may not have asserted general acceptance. Even assuming he did, however, his assertion cannot by itself show general acceptance by a preponderance of the evidence. As we noted above, general acceptance may not be found “[i]f there is a significant dispute between qualified experts as to the validity of scientific evidence.” At the very least, this record shows such a dispute. Accordingly, we hold that latent earprint identification is not generally accepted in the forensic science community.

Nothing in our holding bars testimony at retrial concerning how the latent print was lifted, how the exemplars were taken, or how the overlays were prepared. As the State correctly argues in its brief, “[t]here is nothing novel or scientific about lifting or taking a print whether it be of an ear, a lip or a finger,” and nothing “novel or scientific about taking the print and putting it on an overlay.” Lifting prints and preparing overlays involves technical or other specialized knowledge, but that knowledge has been generally accepted for decades.

Nothing in our holding bars testimony at retrial concerning visible similarities and differences between the latent print and the exemplars. This type of comparison--an “eyeballing” of readily discernable similarities and differences--is based on “visual techniques” that “present jury questions,” or, in alternative terms, on personal knowledge that can readily be understood and evaluated by the jury. Thus, it need not be supported by a showing of general acceptance.

Finally, nothing in our holding bars testimony, based on an appropriate comparison of the latent print with the exemplars, that Kunze cannot be excluded as the maker of the latent print. An opinion of non-exclusion (e.g., that a particular person cannot be excluded as the maker of a latent print) can rationally be based on readily discernable class characteristics, but an opinion of inclusion (e.g., that a particular person made or probably made a latent print) cannot be.

In reaching our holding, we do not overlook the trial court's Finding 15, on which the State heavily relies. In that finding, the trial court stated that “the explanatory principle of ‘individualization,’ that any two items that have a common origin can be compared and an individualization accomplished if the items [are] of a quality that the individuality can be observed, is generally accepted in the branch of forensic science known as criminalistics.” This finding is immaterial here, where the question is whether latent earprint identification is generally accepted (or, in alternative terms, whether earprints in general, and the earprints in this case in particular, are “of a quality that the individuality can be observed”). We agree with and adopt the statements of a commentator who, after noting two generally held tenets–“that no two snowflakes are exactly the same,” and “that no two fingerprints have ever been found to have the same ridge positioning”--states as follows:

In some quarters, these tenets have been scooped up and extended into a single, all- encompassing, generalized principle of uniqueness, which states that “Nature never repeats itself.”
This principle is probably true, although it would not seem susceptible of rigorous proof. But the general principle cannot be substituted for a systematic and thorough investigation of a physical evidence category. One may posit that no two snowflakes are alike, but it does not immediately follow that no two shoe soles are alike, since snowflakes made in clouds and shoes are not. If no two shoe soles are alike, the basis for this uniqueness must rest on other grounds, and those grounds must be identified and enunciated.


We conclude that the trial court erred by allowing Grubb and Van der Lugt to testify that Kunze was the likely or probable maker of the latent, and that a new trial is therefore required.

MARK DALLAGHER CASE: PART SIX; INTRODUCTION OF NEW SCIENCE INTO THE CRIMINAL COURTS; A BARRISTER SPEAKS OUT;



“THIS IS ANOTHER EXAMPLE OF THE DANGERS OF THE POLICE FOLLOWING SCIENTISTS TOO CLOSELY WHEN THE SCIENTISTS ARE BUILDING A SCIENCE, NOT FOLLOWING A SCIENCE”.

JAMES STURMAN Q.C;

-------------------------------------------------------------------------------

British barrister Neil Baki makes an important distinction between scientists who are building a science - and scientists following a science - in a article published in the Criminal Bar Quarterly on March 1, 2009 under the heading, "New Science."

"Establishing the validity of new scientific techniques and theories, and the basis for their interpretation, is essential before evidence derived from them can be used in Court," this section of Baki's article begins.

"It is not always straightforward for Judges to decide whether to admit forensic evidence," it continues;

"The Court of Appeal has recently considered earprint, lip-reading and facial mapping evidence. Indeed, polygraph tests are currently being used in criminal trials in many other countries including Canada and the United States.

Sir Alec Jeffreys has expressed his concern about the lack of protocol in the UK for deciding whether to admit scientific evidence, in relation to the validation of new scientific techniques.

The results of this lack of clarity can be seen in the case of Mark Dallagher, the first man in the UK who was convicted of murdering an 84 year old woman by using an ear-print.

His Counsel, James Sturman Q.C. told the Court, “This is another example of the dangers of the police following scientists too closely when the scientists are building a science, not following a science”.

English courts have used this technique and obtained convictions in three other cases even though it has been widely discredited mainland Europe and the United States.

Daubert Principles:

The UK Court should be more rigorous in its approach to new scientific techniques.

Most states in the US follow well defined procedures to establish whether evidence from a particular scientific technique should be admitted.

According to the Frye Test (named after a defendant in a murder case in 1923), Court can only admit evidence derived from a novel scientific method once it has gained general acceptance within the scientific community to which it belongs.

This test was further developed in the Daubert Test which has four criteria:
(i) whether the theory or technique can be (and has) been tested);

(ii) whether it has been subjected to peer review and publications;

(iii) in the case of a particular technique, what the known or potential rate of
error is or has been;

(iv) whether the evidence has gained widespread acceptance within the scientific ommunity.

The introduction of a similar such test in the UK may serve as a gate-keeping test and act as an early warning sign, particularly in the context of our adversarial system.

MARK DALLAGHER CASE: PART FIVE; UNRAVELLING OF AN "EXPERT"; A LONG OVERDUE BLOW TO EARPRINT COMPARISON EVIDENCE; THE TELEGRAPH;



"THE APPEAL COURT AIRED CONCERNS ABOUT MR VAN DER LUGT'S EXPERTISE. HE WAS A POLICE OFFICER OF 27 YEARS EXPERIENCE BUT HAD NO FORMAL QUALIFICATIONS. HE HAD "SIMPLY BECOME INTERESTED IN EAR PRINT IDENTIFICATION".

THE JUDGES RULED DALLAGHER'S CONVICTION UNSAFE BUT ORDERED THAT HE REMAIN IN PRISON PENDING A RETRIAL.

THAT HEARING BEGAN IN MANCHESTER LAST JUNE BUT WAS HALTED AFTER THE RECEIPT OF NEW EVIDENCE AND THE LAUNCH OF A FRESH INQUIRY. IT RESUMED YESTERDAY WITH THE CROWN SAYING IT WOULD OFFER NO EVIDENCE. THE DEFENCE REVEALED THAT DNA FROM ONE OF THE ORIGINAL EARPRINTS SHOWED IT COULD NOT HAVE BEEN MADE BY DALLAGHER."

THE TELEGRAPH:

-------------------------------------------------------------------------------

The unravelling of earprint evidence in Europe and North America was described in a story which appeared in The Telegraph on January 22, 2004, without a by-line, under the heading, "'Breakthrough' looks less and less convincing."

The sad part of the story is that Mark Dallagher remained behind bars for seven horrific years as a murderer while the reputations of Cornelis van der Lugt and his pseudo science became unravelled.

Although several people had been convicted in England because of earprint evidence - which the courts had begun to accept as fact - it had become apparent, however, that there is little scientific basis for this.

The reality was that experts did not have a database of earprints, nor a scientific method of comparing prints, apart from laying the suspect's print on top of the one found at the scene and examining them for differences.

Prof Peter von Coppen, of Leiden University in Holland, had issued a paper disputing earprint evidence in which he said: "There has been no research done in which you can say, for instance, what the national distribution of lobes is, so you don't know if the earprint is one which would match 80 per cent of everyone else's or whether it has unique characteristics."

Far too many innocent persons would have been avoided horrific consequences - including the death penalty - if judges had exercised their gate-keeper function and protected them from so-called experts such as, Charles Smith, Michael West, Steven Hayne, Louise Robbins and Cornelis van der Vugt.

"Two smudged earprints made by a burglar who pressed his head to Dorothy Woods's window before jemmying it open were the only clues police found when they discovered the 94-year-old spinster murdered in her bed," the Telegraph story began.

"The West Yorkshire police turned to Cornelis van der Lugt, a Dutch former scenes of crime officer who had made himself the world expert in the fledgling science of earprint identification," it continued;

"At the trial of 26-year-old Mark Dallagher, it was the Dutchman's testimony that sealed a conviction.

Prof Peter Vanezis, a leading British forensic scientist, did not go quite as far as Mr van der Lugt in saying the evidence pointed to Dallagher, but said he thought it "highly likely" that Dallagher left his earmarks on the window above Miss Woods's bed.

The case was hailed as representing an important breakthrough in forensic techniques. "We now have another weapon in our arsenal against crime," said one investigating officer.

The Crown Prosecution Service went further, claiming in its 1999 annual report that the case had "made legal history".

But even as that report was published, the scientific evidence underpinning the conviction was unravelling.

A court in the United States upheld an appeal by David Kunze who had been convicted of aggravated murder on the evidence of Mr van der Lugt that his earprints had been found at the crime scene. The judges said Mr van der Lugt's theories on earprints were "not generally accepted in the forensic science community" and his evidence should have been inadmissible.

In May 2000 a court in Amsterdam overturned a conviction in another case where van der Lugt had given expert evidence. The Dutch court said that the infant discipline of earprinting should be treated "with caution and reservations".

Dallagher continued to protest his innocence, claiming that he had been at home with his girlfriend on the night of the killing in 1996. His appeal was heard in July 2002.

The Appeal Court aired concerns about Mr van der Lugt's expertise. He was a police officer of 27 years experience but had no formal qualifications. He had "simply become interested in ear print identification".

The judges ruled Dallagher's conviction unsafe but ordered that he remain in prison pending a retrial.

That hearing began in Manchester last June but was halted after the receipt of new evidence and the launch of a fresh inquiry. It resumed yesterday with the Crown saying it would offer no evidence. The defence revealed that DNA from one of the original earprints showed it could not have been made by Dallagher.

Despite Dallagher's acquittal, Mr van der Lugt told The Telegraph that his faith in earprinting remained strong. He is involved in a multi-million pound European Union-funded research project that aims to produce European earprinting standards."

MARK DALLAGHER CASE: PART 4; FIRST INTERVIEW ON RELEASE AFTER 7 YEARS ; GUINEA PIG FOR NEW "SCIENCE"; THE TOLL THAT IT TAKES; THE YORKSHIRE POST;


"MARK DALLAGHER, A SMALL-TIME BURGLAR FROM HUDDERSFIELD, LATER BECAME THE FIRST PERSON IN BRITISH HISTORY TO BE CONVICTED ON THE EVIDENCE OF AN EARPRINT AFTER POLICE EXPERTS SAID THEY WERE 100 PER CENT SURE THAT HIS WAS AN EXACT MATCH FOR THE MURDERER'S. IT WAS SUPPOSED TO BE THE NEXT BIG THING IN CRIMINAL INVESTIGATIONS – A NEW TYPE OF EVIDENCE AS TRUSTWORTHY AS A FINGERPRINT WHICH COULD PROVE CRUCIAL IN THE FUTURE. YET MR DALLAGHER WAS RELEASED IN JANUARY THIS YEAR AFTER NEW DNA GENETIC EVIDENCE PROVED CONCLUSIVELY THAT THE EARPRINT COULD NOT HAVE BEEN HIS........."

-------------------------------------------------------------------------------

"HIS SINGLE BED IS SURROUNDED BY PHOTOGRAPHS AND CARDS, AND HE REFERS TO HIS BEDROOM AS HIS "CELL". IT IS THE ONLY PLACE, HE SAYS, WHERE HE FEELS SAFE FROM THE WORLD THAT LET HIM DOWN SO BADLY.

"YOU CAN'T JUST TAKE A MAN'S WHOLE LIFE OFF HIM, TAKE HIS FREEDOM AWAY FROM HIM AND JUST PUT HIM AWAY FOR EIGHT YEARS AND THEN KICK HIM BACK OUT AFTER EIGHT YEARS AND SAY, 'OK, GO ON, YOU'RE ALL RIGHT.'

"IT DOESN'T WORK LIKE THAT," HE SAYS.

REPORTER KATE O'HARA: YORKSHIRE POST;"

-------------------------------------------------------------------------------
Reporter O'Hara's story, containing the first interview with Mark Dallagher following his release, ran on September 29, 2004, under the heading, "Earmarked – for rough justice."

The story carried the sub-heading: "An earprint on a window pane landed Mark Dallagher in prison for seven years for a murder he did not commit. Now he breaks his silence about the flawed evidence."

"WHEN 94-year-old Dorothy Wood was murdered, the only real clue to her killer was an earprint left as he listened at her window," the story begins;

"Ms Wood, a retired health visitor who was profoundly deaf, was found dead in bed at her home in Whitby Avenue, Fartown, on May 7, 1996. She had been smothered by a pillow," it continues;

"Mark Dallagher, a small-time burglar from Huddersfield, later became the first person in British history to be convicted on the evidence of an earprint after police experts said they were 100 per cent sure that his was an exact match for the murderer's.

It was supposed to be the next big thing in criminal investigations – a new type of evidence as trustworthy as a fingerprint which could prove crucial in the future. Yet Mr Dallagher was released in January this year after new DNA genetic evidence proved conclusively that the earprint could not have been his.

In his first interview since being released in January after a "grotesque miscarriage of justice" that saw him locked up for seven years, he still looks shocked that investigators could get it so spectacularly wrong.

Shaking his head constantly during an hour-long documentary that follows him throughout his time in prison, his appeal, his retrial and eventual release, Mr Dallagher says he is finding it hard to cope with life since his release.

He has moved in with his fiancee, yet has his own room which he has fashioned into a mirror image of the cell he spent seven years bitterly fighting to escape from. He folds up his towel and flannel after washing, and packs his soap and toothbrush neatly onto the stack, just as he did in prison.

His single bed is surrounded by photographs and cards, and he refers to his bedroom as his "cell". It is the only place, he says, where he feels safe from the world that let him down so badly.

"You can't just take a man's whole life off him, take his freedom away from him and just put him away for eight years and then kick him back out after eight years and say, 'OK, go on, you're all right.'

"It doesn't work like that," he says.

"Because I'm struggling, you know, and I'm 30 years old but I'm struggling going to town centres and getting a bus and using a pay phone. Everything is hard, everything. I don't know how to use mobile phones, and I don't know how to work DVD players. I'm having to learn everything."

A jury unanimously found Mr Dallagher, formerly of Honoria Street, Fartown, Huddersfield, guilty of smothering Ms Wood, after being told by a Dutch expert that the famous earprint must have been his.

But a retrial was ordered by the Court of Appeal in 2002 after his conviction was found to be unsafe.

A new investigation was launched, and in January, when the prosecution offered no evidence against him, Judge Sir Stephen Mitchell formally found him not guilty of Ms Wood's murder.

Yet nobody has ever apologised to Mr Dallagher for taking seven years of his life, and no one has been convicted of Ms Wood's murder. West Yorkshire Police say they consider the matter "closed".

For Mr Dallagher, who told his fiancee and his father Mick that he would commit suicide if he lost his appeal, the matter is far from closed.

His voice cracking with emotion, he says: "I'm fighting for my life here, that's all I've been able to do. But there is still a murderer out there."

West Yorkshire Police said last night: "Having re-examined the case, the force has not found any evidence to lead to the prosecution of any other suspects for the murder of Dorothy Wood.

"Therefore we consider the matter closed until any further admissible evidence comes to light.""

MARK DALLAGHER CASE: PART THREE; BBC REPORT OF HIS MURDER CONVICTION LAUDED ROLE PLAYED BY "EXPERT" EARPRINT EVIDENCE; "A GREAT STEP FORWARD";


"NORMAN SARSFIELD, OF WAKEFIELD CROWN PROSECUTION SERVICE, SAID THE VERDICT WAS "A GREAT STEP FORWARD FOR FORENSIC EVIDENCE".

HE SAID: "THIS IS PROBABLY THE FIRST TIME THAT SUCH EVIDENCE HAS BEEN USED SUCCESSFULLY IN A MURDER TRIAL AND WILL FORM THE BASIS OF CASE LAW IN THE FUTURE.

"IN PLANNING TO USE THE EAR-PRINT EVIDENCE WE SOUGHT THE ADVICE OF EXPERTS IN ORDER TO PROVE THAT IT COULD NOT HAVE BELONGED TO ANYONE ELSE." "

BBC CORRESPONDENT: JOHN CUNDY;

-------------------------------------------------------------------------------
UK: The BBC's December 15, 1998 report lauded the contribution expert earprint evidence had made to Mark Dallagher's murder conviction;

Readers would have rested content that thanks to science the right man had been convicted and justice was done - which, of course, turned out to be anything but the truth;

The story, by correspondent John Cundy, ran under the heading, "Ear print catches murderer." (Dallagher who had vociferously protested his innocence from the outset was now a murderer);

Sub-headings included: "Dorothy Wood (centre) was suffocated with a pillow during a burglary," and, "An innovative if bizarre piece of evidence," "Dallagher's distinctive earprint was found on Mrs Wood's window," and "Great step forward."

"A man has been convicted of murdering an elderly spinster on the basis of "earprint" evidence, in what is believed to be a legal first," Cundy's report began.

"Mark Dallagher, 25, from Huddersfield, West Yorkshire, was caught after police matched an imprint left on the window of the 94-year-old victim's home with his ear," the report continued;

"Dorothy Wood, who was frail and profoundly deaf, was smothered with a pillow at her home in Fartown, Huddersfield in May 1996. the report continued;

"The court heard evidence during the two-week trial from international ear experts including Cornelis Van Der Lugt of the Netherlands, that the ear print was a unique match to Dallagher.

Detectives believe Dallagher put his ear to Mrs Wood's window to listen for signs of anyone in the house.

Norman Sarsfield, of Wakefield Crown Prosecution Service, said the verdict was "a great step forward for forensic evidence".

Jonathan Hallewell reports: Dallagher denied being the murderer
He said: "This is probably the first time that such evidence has been used successfully in a murder trial and will form the basis of case law in the future.

"In planning to use the ear-print evidence we sought the advice of experts in order to prove that it could not have belonged to anyone else."

Dallagher, who denied murder, was jailed for life at Leeds Crown Court.

Afterwards his sister, who declined to give her name, insisted he was innocent and said she planned to appeal."

MARK DALLAGHER CASE: PART TWO; "EXPERT" EARPRINT EVIDENCE PUTS MAN BEHIND BARS FOR SEVEN YEARS BEFORE HE'S CLEARED BY DNA; TELEGRAPH STORY;



"IN THE WEEK OF THE JUDGMENT IN THE ANGELA CANNINGS CASE - WHICH HAS LED TO A REVIEW OF 258 CONVICTIONS WHERE COT DEATH EXPERTS TESTIFIED - THIS RAISED FRESH QUESTIONS ABOUT EXPERT EVIDENCE, HE ADDED.

MR STURMAN SAID: "THIS IS ANOTHER EXAMPLE OF THE DANGERS OF THE POLICE FOLLOWING SCIENTISTS TOO CLOSELY WHEN THE SCIENTISTS ARE BUILDING A SCIENCE NOT FOLLOWING A SCIENCE.""

SEAN O'NEILL: THE TELEGRAPH;

-------------------------------------------------------------------------------
The Telegraph story by reporter Sean O'Neill ran under the heading, "Expert evidence flaws clear 'earprint killer'" on January 23, 2004;

"A man convicted of murder on the basis of an earprint was acquitted at a retrial yesterday after the expert evidence that jailed him was shown to be flawed," the story began.

"The collapse of the case against Mark Dallagher, which made legal history in 1998 when he became the first man to be convicted of murder by earprint evidence, is another blow to the credibility of expert witnesses," the story continued;

"The handful of convictions obtained using earprint identification techniques may now have to be re-examined.

Dallagher, 31, was cleared at the Old Bailey of murdering 94-year-old Dorothy Woods after a DNA analysis of earprints left at the murder scene undermined expert testimony that they were made by him.

A jury at Leeds Crown Court had found him guilty in 1998 after Cornelis van der Lugt, a Dutch former policeman turned earprint expert, said he was "absolutely convinced" that Dallagher had made the prints found on Miss Woods's window.

The prosecution claimed that Dallagher, a convicted burglar, had left the prints while listening at the window before breaking into the house in Huddersfield in May 1996.

But following an appeal, a retrial and a fresh police investigation the Crown said it had "anxieties" about the case and was offering no evidence against Dallagher.

James Sturman, QC, defending, said Dallagher was the victim of "a grotesque miscarriage of justice" who had spent almost six years in prison and always maintained his innocence.

"The killing of Dorothy Woods was a wicked crime that had nothing to do with Mark Dallagher," said Mr Sturman.

In the week of the judgment in the Angela Cannings case - which has led to a review of 258 convictions where cot death experts testified - this raised fresh questions about expert evidence, he added.

Mr Sturman said: "This is another example of the dangers of the police following scientists too closely when the scientists are building a science not following a science."

Sir Stephen Mitchell, the judge, said "this most unfortunate saga" was now at an end.

"It was the most terrible killing and the centrepoint of the evidence was the earprint - scrutiny and examination of earprints was then in its infancy," he added.

The judge said it was "refreshing" that West Yorkshire police had carried out a new inquiry leading to Dallagher's acquittal.

He recorded a not guilty verdict and wished Dallagher well.

The defendant, who was in court with his fiancee, Karen De'ath, thanked the judge.

Outside court, Neil O'May, Dallagher's solicitor, said his client wanted police to pursue the case to find the real killer.

"DNA evidence flatly contradicts the original prosecution case because the DNA found was not Mark Dallagher's," said Mr O'May.

"Mr Dallagher has been very angry about the way he has been prosecuted and the reliance on so-called expert earprint evidence.

"This is another case where a serious miscarriage of justice has occurred because of unreliable science."

West Yorkshire police admitted that new evidence "challenges the science of earprint identification". A police spokesman said: "Having re-examined the case the force has not found any evidence to lead to the prosecution of any other suspects for the murder of Dorothy Wood.

"Therefore we consider the matter closed until any further admissible evidence comes to light.""

MARK DALLAGHER CASE: PART 1; MORE ON BRITISH REPORT CALLING FOR EXPERT WITNESS REFORMS: "THE TELEGRAPH" CITES NOTORIOUS EARPRINT EVIDENCE CASE;


"IN ANOTHER CASE MARK DALLAGHER, 30, SPENT NEARLY SEVEN YEARS IN JAIL PROTESTING HIS INNOCENCE AFTER AN OLD BAILEY JURY WAS TOLD BY AN EXPERT, A DUTCH POLICE INSPECTOR, THAT EARPRINTS FOUND AT A MURDER CRIME SCENE MATCHED HIS EXACTLY."

REPORTER CHRISTOPHER HOPE: THE TELEGRAPH; PHOTO: MARK DALLAGHER'S SO-CALLED "DISTINCTIVE" EARPRINT;

-------------------------------------------------------------------------------

In his report on the release of the British Law Commission report earlier this week reporter Christopher Hope refers to the Dallagher case - in which then 30-year-old Mark Dallagher was wrongfully convicted after a jury was told by an "expert" that earprints found at a murder crime scene matched his exactly.

The Dallagher case is a classical example of judges abandoning their gatekeeper function in the face of non-scientifically proven evidence as demonstrated by Drs. West and Hayne in the U.S.A. with their ludicrous "bitemark" theories, Dr.Louise Robbins (also U.S.A.) and her destructive footprint evidence, and Dr. Charles Smith in Canada who saw things during an autopsy on a child that no-one else could see.

Hope's story ran under the the following heading (fully reflective of the government's spin): "Criminals could have been wrongly freed by the courts because of unreliable evidence from expert witnesses, the Government's law advisers say today."

"The Law Commission is recommending a new "quality test" which expert witnesses will have to pass before giving evidence in criminal trials, Hope's story, published on April 6, 2009, begins;

"The crackdown comes after a series of miscarriages of justice arising from unsafe evidence from expert witnesses," the story continues;

"Jeremy Horder, the Commissioner leading the project, added that some guilty criminals had been wrongly freed.

Prof Horder said: "There have been miscarriages of justice in recent years where prosecution expert evidence of doubtful reliability has been placed before Crown Court juries.

"There may also have been unwarranted acquittals attributable to such evidence.

"We want to ensure that the criminal courts have the means to authenticate expert evidence and be satisfied that the information before them is sound."

The Law Commission will propose at the start of a three-month consultation that judges adopt a new "statutory test for determining the admissability of an expert witness in criminal proceedings".

If an expert witness does not pass the test, then his or her evidence cannot be heard in court.

Prof Horder added: "We want to ensure that the criminal courts have the means to authenticate expert evidence

and be satisfied that the information before them is sound."

The Commission also recommends new guidelines for Crown Court judges and magistrates' courts to help them determine whether expert evidence is sufficiently reliable to be admitted.

One of the most high profile miscarriages of justice was in 1999, when Sally Clark was jailed for killing her 11-week-old son Christopher in December 1996, and eight-week-old Harry in January 1998.

An appeal in 2000 failed, but she was freed in 2003 after a fresh appeal. She was found dead in 2007.

The jury at her trial was told by an expert witness, Professor Sir Roy Meadow, that the probability of two natural unexplained cot deaths in a family was 73 million to one. Other experts said the odds were about 200 to one.

In another case Mark Dallagher, 30, spent nearly seven years in jail protesting his innocence after an Old Bailey jury was told by an expert, a Dutch police inspector, that earprints found at a murder crime scene matched his exactly.

After the Court of Appeal ordered a retrial, a DNA sample from the earprint proved it was not Mr Dallagher's.

In December 2007 the biggest criminal investigation in the history of British sport collapsed after a series of police and Crown Prosecution Service blunders which led to the inquiry being branded "incompetent''.

The error which finally sank the case was the prosecution's reliance on an Australian racing steward as their expert witness. He was ridiculed in court when he admitted he did not know the rules of UK horse racing."
