Criminal procedure; clarifying and including additional evidentiary disclosure requirements for prosecutors; effective date.

HB 1317 requires Oklahoma prosecutors to disclose additional evidence to defense attorneys upon request, directly affecting prosecutors, defense teams, and criminal defendants. Key provisions mandate sharing witness statements (including contact info), police reports, forensic lab results (with privacy protections for SSN/address), and all evidence that could help the defense (e.g., evidence negating guilt or impeaching witnesses). The bill clarifies that prosecutors must make a "diligent, good faith effort" to locate discoverable material, even if not in their direct possession. It aims to standardize disclosure under Oklahoma’s criminal discovery rules, ensuring broader access to relevant case information before trial.
