Administrative procedure: judicial review; judicial review of administrative rules; modify. Amends sec. 61 of 1969 PA 306 (MCL 24.261).

This bill modifies Michigan's Administrative Procedures Act to clarify how courts should review administrative rules. It establishes that publishing a rule in the official register creates a legal presumption that the rule was properly adopted and filed, and it requires courts to take judicial notice of rules that have become effective. Additionally, the bill instructs judges to exercise independent judgment when determining if an agency acted within its legal authority, specifically prohibiting deference to an agency's interpretation of ambiguous laws. These changes directly affect state agencies that create regulations and the courts that adjudicate challenges to those regulations.
