HB 606 introduces a significant change to how courts and administrative law judges interpret state laws and rules. The bill requires judges in judicial and administrative hearings to apply de novo review when interpreting state statutes, agency rules, or guidance documents. This means judges must independently assess the meaning and application of laws without giving deference to state agency interpretations. Additionally, when a law or rule is ambiguous, the bill mandates that judges resolve the ambiguity in favor of limiting the authority of the state agency involved. This approach emphasizes judicial independence in interpreting laws and reduces the influence of agencies on judicial decisions.
