OK HB3503

Requires the state to disclose evidence within 30 days of the defendant's initial appearance, rather than upon request, including full contact information for all witnesses interviewed during the investigation, law enforcement reports, body camera and dashboard camera footage, and audio/video recordings

Expands mandatory disclosure of exculpatory evidence to include information that negates guilt, reduces culpability, supports potential defenses, impeaches prosecution witnesses, undermines identification evidence, supports suppression motions, or mitigates punishment—regardless of whether the evidence is recorded or whether the prosecutor believes it credible

Increases the disclosure deadline for informant testimony from 10 days to 30 days before trial and expands the definition of "informant" beyond jailhouse informants to include codefendants and others who provide testimony about defendant admissions

Extends discovery completion deadline from 10 days to 30 days before trial, requires law enforcement to provide body camera, vehicle camera, and sobriety test recordings to prosecutors within 30 days of filing charges, and authorizes contempt sanctions for law enforcement noncompliance

Establishes mandatory sanctions for discovery violations unless the court finds the failure harmless or unavoidable, with available sanctions including evidence preclusion, case dismissal, mistrial, contempt, and monetary penalties
