Oklahoma Criminal Discovery Code; requiring certain disclosures by the state; requiring certain disclosure by the defense. Effective date.

SB 1267 updates Oklahoma's criminal discovery rules to require both prosecutors and defense attorneys to disclose specific evidence earlier in the legal process. Prosecutors must share witness information, physical evidence in usable formats, expert reports with underlying data, and details about "jailhouse informants" (people who get testimony from incarcerated individuals in exchange for deals). Defense attorneys must disclose their own witnesses and mental health expert information. The bill also mandates electronic submission of certain reports and creates a confidential statewide database for tracking informant-related cases, while requiring prosecutors to provide defense with all evidence favorable to the defendant.
