restrict deference to a state agency's interpretation of a state statute, administrative rule, or policy.

SB 134 requires South Dakota courts and administrative hearing officers to interpret state statutes, rules, and policies independently ("de novo") instead of giving special weight to a state agency's interpretation. It prohibits courts from deferring to agency views and mandates that any remaining uncertainty must be resolved in favor of interpretations consistent with individuals' constitutional rights. This directly affects state agencies, courts, and anyone challenging agency actions or interpretations in court. The bill changes how legal disputes involving agency rules are reviewed, ensuring courts make final decisions without relying on agency explanations.
