WHITE, J.
The appellants commenced this action in the District Court for Lincoln County, Nebraska, challenging the constitutionality of Neb. Rev. Stat. § 23-114 to 23-114.05, 23-168 to 23-168.04, 23-172, 23-173, 23-173.01, 23-174, 23-174.02, 23-373, and 23-376 (Reissue 1977) relating to establishment and promulgation of zoning regulations by the county commissioners of Lincoln County. The trial court held the statutes constitutional. We dismiss the appeal.
Appellants failed to notify the Attorney General by serving a copy of their brief on him within 5 days of the filing of their brief in this court pursuant to Neb. Ct. R. 16A (Rev. 1982) (formerly rule 18). Rule 16A states: "Cases Involving Constitutional Questions. A party presenting a case involving the constitutionality of a statute must file a written notice thereof with the Clerk of this court at the time of filing his brief. If the Attorney General is not already a party to an action where the constitutionality of the statute is in issue, a copy of the brief assigning unconstitutionality must be served on the Attorney General within 5 days of the filing of the brief with the Clerk of this court; proof of such service shall be filed with the Clerk of this court."
The appellants having failed to comply with the rules of this court, the appeal is dismissed.
APPEAL DISMISSED.
