Relating to requiring the corroboration of certain testimony in a criminal case involving a controlled substance.

HB 870 requires additional evidence to support convictions in drug-related cases where undercover law enforcement testimony is used. Specifically, it mandates that testimony from undercover officers or informants in cases under Chapter 481 (Health and Safety Code) must be corroborated by other evidence directly linking the defendant to the crime. This applies to all cases where a conviction is based solely on such testimony, excluding corroboration that only proves the crime occurred. The law would take effect September 1, 2025, and would apply to all cases with judgments entered on or after that date. It directly affects defendants in drug trafficking or possession cases relying on undercover witness testimony.
