(d) Within 30 days after service on the agency or notice to other parties of the petition as provided in K.S.A. 77-615, and amendments thereto, a party to judicial review proceedings may file an answer or other responsive pleading and shall serve a copy of any such answer or pleading in the manner provided by subsection (e) of K.S.A. 77-613, and amendments thereto, upon all parties to the proceedings. (e) In any method of serving process, substantial compliance shall effect valid service of process if the court finds that, notwithstanding some irregularity or omission, the party served was made aware that the petition or appeal had been filed.
