How to challenge a government authority decision in administrative court

When this applies

This guide applies when a state au­thor­i­ty, local gov­ern­ment, or another public au­thor­i­ty has issued an in­di­vid­ual de­ci­sion, taken action, or failed to do some­thing it was re­quired to do. The purpose of an ad­min­is­tra­tive claim is to protect a spe­cif­ic right in a public-law re­la­tion­ship, not simply to express dis­agree­ment with an in­sti­tu­tion.

The first ques­tion is not the de­fen­dant’s name but the nature of the dispute. If the au­thor­i­ty acted as a prop­er­ty owner, an em­ploy­er outside the public-service regime, or a party to a private con­tract, the case may belong in civil or com­mer­cial court. Article 19 of the Code of Ad­min­is­tra­tive Pro­ce­dure helps dis­tin­guish an ad­min­is­tra­tive case, but some cat­e­gories have special rules.

Do not confuse this route with an appeal against a de­ci­sion under the Code of Ukraine on Ad­min­is­tra­tive Of­fens­es. Tax and customs dis­putes, elec­tions, en­force­ment actions, sanc­tions, public pro­cure­ment and An­ti­mo­nop­oly Com­mit­tee de­ci­sions, reg­u­la­tions, public-private part­ner­ships, and con­ces­sions also require sep­a­rate checks.

Applicable deadline or procedure

Under the general rule in Article 122 of the Code of Ad­min­is­tra­tive Pro­ce­dure, an in­di­vid­ual has 6 months to protect their rights. The period does not nec­es­sar­i­ly start on the date printed on the de­ci­sion; it starts when the person learned or should have learned of the vi­o­la­tion. An en­ve­lope, track­ing record, elec­tron­ic cabinet notice, or ac­knowl­edg­ment of access may there­fore matter more than the date on the first page.

If the law allows pre­tri­al review and the person used it on time, the usual period after service of the com­plaint de­ci­sion is 3 months. If no de­ci­sion was made or served within the re­quired period, the 6-month period runs from the day the com­plaint was filed. A 1-month period applies to entry into public service, service, and dis­missal from it.

The ad­min­is­tra­tive court dead­line cal­cu­la­tor shows these four routes, but de­lib­er­ate­ly stops when the special dead­line, ju­ris­dic­tion, or base date is not con­firmed. That stop is safer than a con­vinc­ing but in­cor­rect date.

The period starts the day after the rel­e­vant event. A period set in months ends on the cor­re­spond­ing date, or on the last day of the month if that date does not exist. If the final day is Sat­ur­day or Sunday, the cal­en­dar es­ti­mate moves forward. Doc­u­ments may be sent by a per­mit­ted method until 24:00 on the final day; keep proof of the sending time.

Pro­ce­dur­al dead­lines are not au­to­mat­i­cal­ly sus­pend­ed during martial law. Do not me­chan­i­cal­ly add the prewar holiday cal­en­dar either. Spe­cif­ic ob­sta­cles may support a motion to renew the dead­line, but facts and ev­i­dence are re­quired.

What to do step by step

First keep the com­plete de­ci­sion and proof of when it was re­ceived. If the chal­lenge con­cerns an omis­sion, doc­u­ment your request to the au­thor­i­ty, its duty to act, ex­pi­ra­tion of the ap­plic­a­ble period, and lack of a result. For a Kyiv au­thor­i­ty, verify its exact legal name, iden­ti­fi­ca­tion code, and address instead of relying on the de­part­ment name in cor­re­spon­dence.

Next de­ter­mine ju­ris­dic­tion and venue. Explain which public-au­thor­i­ty func­tion the de­fen­dant per­formed and which of your rights was vi­o­lat­ed. Then find the rule gov­ern­ing this cat­e­go­ry and check for a special dead­line or manda­to­ry pre­tri­al pro­ce­dure.

For­mu­late reme­dies so the de­ci­sion can ac­tu­al­ly restore the right: declare the de­ci­sion un­law­ful and cancel it, declare an action or omis­sion un­law­ful, require the au­thor­i­ty to act, or use another remedy pro­vid­ed by law. The claims must fit the facts and the ad­min­is­tra­tive court’s powers.

Prepare the claim under Ar­ti­cles 160–161 of the Code. Attach ev­i­dence, proof of court-fee payment or an ex­emp­tion, elec­tron­ic cabinet in­for­ma­tion, rep­re­sen­ta­tive doc­u­ments, and proof that copies were sent. If the dead­line may have passed, submit a motion to renew it with a time­line and ev­i­dence at the same time.

Before paying for a Kyiv case, check the ad­min­is­tra­tive claim fee and the proper court details. A cal­cu­la­tion for a civil or com­mer­cial dispute does not confirm payment for an ad­min­is­tra­tive claim.

What to check before filing

Compare three dates: the de­ci­sion date, the actual service date, and the date the vi­o­la­tion became known from another source. The court may con­sid­er not only actual knowl­edge but also when the person should have learned of the vi­o­la­tion. Passive waiting without an ex­pla­na­tion does not always justify a late claim.

Check whether the pre­tri­al com­plaint was ac­tu­al­ly filed on time and whether the law ties a sep­a­rate dead­line to it. Keep its reg­is­tra­tion number, in­ven­to­ry of con­tents, receipt, or elec­tron­ic con­fir­ma­tion. If the reply arrived late, do not au­to­mat­i­cal­ly assume a new 6 months began on the reply date.

Review every at­tach­ment: is it read­able, does it show the date, is the full text and sig­na­ture present, and is it clear which state­ment it sup­ports? For elec­tron­ic filing, check the qual­i­fied sig­na­ture and de­liv­ery receipt; for mail, the in­ven­to­ry and receipt; for in-person filing, a stamp on your copy.

When to consult a lawyer

Legal review is es­pe­cial­ly im­por­tant when the dead­line is short or has passed, the au­thor­i­ty relies on a special pro­ce­dure, a de­ci­sion has gone through pre­tri­al review, the dispute borders on civil or com­mer­cial ju­ris­dic­tion, or a se­quence of au­thor­i­ty actions must be chal­lenged rather than one doc­u­ment.

For a Kyiv case, a con­sul­ta­tion can compare venue, the proper de­fen­dant, remedy, dead­line cal­cu­la­tion, and service ev­i­dence before the claim is sent. This does not guar­an­tee an outcome, but reduces the risk of losing time through the wrong route or an in­com­plete claim package.
