Relating to a district or county attorney participating as counsel in certain proceedings.

HB 917 restricts district and county attorneys from representing opposing sides in legal cases against the state, both during and after their employment. Specifically, it prohibits them from serving as "counsel adversely to the state" in any court case except in limited family law matters (as an attorney ad litem under Family Code Chapter 262) and bars them from taking such opposing roles after leaving office if they previously represented the state. The law applies only to offenses committed on or after its effective date of September 1, 2025, leaving prior cases governed by existing law. This aims to prevent conflicts of interest by ensuring prosecutors do not later work against the state they once represented.
