OK SB819

Amends 75 O.S. 2021, Section 318 to establish that a claim under the Administrative Procedures Act accrues when any properly joined plaintiff has the right to assert the claim in court, with the earliest date being when the party is aggrieved by final agency action.

Requires courts and administrative hearing officers to interpret state statutes, administrative rules, and subregulatory documents de novo without deference to agency interpretations, and to resolve any remaining doubt in favor of limiting agency power and maximizing individual liberty.

Prohibits civil penalties in actions brought by or on behalf of administrative agencies against persons or legal entities for conduct that would be subject to common law suits with jury trial rights, except after a jury trial; provides exceptions for summary judgments and certain equity jurisdiction cases that predated this act.

Allows agencies to recover court costs, witness fees, and reasonable attorney fees from parties bringing frivolous proceedings or proceedings intended to delay final agency orders, and allows aggrieved parties to recover such fees from agencies that bring frivolous proceedings.

Becomes effective November 1, 2025.
