"Solidifying grounds for relief under Texas junk-science writ: Grits has described the importance HB 3724
by Herrero/Whitmire in defending the jurisdiction of the courts to
provide habeas corpus relief to defendants whose convictions hinged on
junk science, whether because the forensic field at the time got it
wrong or because an individual scientist did. Its passage comes with a
decision pending from the Court of Criminal Appeals in Ex Parte Robbins
III, which is now (un)complicated by the passage of a statute codifying
their ruling in Robbins II. The upshot of HB 3724 is that Texas' junk-science writ will become a
highly functional tool in the judicial arsenal to correct error in junk
science cases, as opposed to a seldom-used one that ignores most
erroneous expert testimony. As Judge Cheryl Johnson pointed out in her
concurrence in Robbins II, as a practical matter judges don't evaluate
science but evidence, and in the case of forensics in particular, testimony.
So HB 3724 ensured that judges could directly confront the most common
source of false convictions based on forensics that the Texas Court of
Criminal Appeals sees on a fairly regular basis."
