Idaho Code § 1-213: Duty to make rules — Limitation.

(1) The supreme court shall prescribe, by general rules, for all the courts of Idaho, the forms of process, writs, pleadings and motions, the manner of service, time for appearance, and the practice and procedure in all actions and proceedings. Said rules shall neither abridge, enlarge, nor modify the substantive rights of any litigant.

(2) The Idaho legislature may review any court rules, including but not limited to the Idaho rules of family law procedure, the Idaho court administrative rules, or the Idaho juvenile rules. Upon any finding of conflict between court rule and Idaho Code, of rules abridging, enlarging, or modifying substantive rights, the legislature shall advise the supreme court of such conflict through a house or senate resolution.
