A man whose execution was halted will testify at a legislative hearing about a “junk science” law in Texas that many say should have saved him long ago

When Robert Roberson’s execution was abruptly halted in Texas, it was due to a subpoena ordering him to testify over a legal backstop that both Republicans and Democrats say should had saved him long ago: Texas’ junk science law.

The 2013 law allows a person convicted of a crime to seek relief if the evidence used against them is no longer credible. At the time, it was hailed by the Legislature as a uniquely future-proof solution to wrongful convictions based on faulty science. But Roberson’s supporters say his case points to faults in the judicial system where the law has been weakened by deliberate misinterpretation from the state’s highest criminal court.

On Monday, Roberson is scheduled to testify to members of a state House committee, four days after he had been scheduled to die by lethal injection.
