In all criminal cases, when a complaint is filed charging a defendant with commission of any crime whereby the underlying factual basis includes an act of domestic violence, as defined in K.S.A. 2020 Supp. 21-5111, and amendments thereto, the court may place a “DV” designation in the unique identifying case number assigned to such case. Nothing in this section shall be construed to limit the courts of this state from adopting a system of case designation deemed by the courts to be beneficial to the efficient administration of justice.
