if the Attorney General is not already a party to the action, 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 Supreme Court Clerk. A review of the record in this case reveals that Ptak failed to file a notice of a constitutional question and failed to serve upon the Attorney General, who is not a party to this action, a copy of his brief. This court has repeatedly held that strict compliance with rule 9E is required for the court to address a constitutional claim. See State v.

McDowell, 246 Neb. 692, 522 N.W.2d 738 (1994) (<HOLDING>). See, also, In re Interest of Rebecka P., 266
