Crim­i­nal cas­sa­tion

Criminal cassation deadline calculator

After an ap­pel­late de­ci­sion in crim­i­nal pro­ceed­ings, it matters whether the clock starts on pro­nounce­ment or service of a copy. For cases from Kyiv and Kyiv region, the tool shows a pre­lim­i­nary last day after you check whether that de­ci­sion can be chal­lenged in cas­sa­tion.

Preliminary criminal cassation calendar

Three cal­en­dar months under Article 426 of Ukraine's Crim­i­nal Pro­ce­dure Code; the date itself does not es­tab­lish a right to cas­sa­tion.

Which event starts the period?

Use the date in the ap­pel­late de­ci­sion or proof that the copy was served on the con­vict­ed person in custody.

Not every ap­pel­late de­ci­sion can be chal­lenged in cas­sa­tion. Check the type of de­ci­sion, who may apply and the scope of Ar­ti­cles 424–425 of the Crim­i­nal Pro­ce­dure Code of Ukraine.

What the three-month calculation covers

Article 426 of Ukraine's Crim­i­nal Pro­ce­dure Code allows three months to file a cas­sa­tion com­plaint from pro­nounce­ment of the ap­pel­late de­ci­sion. For a con­vict­ed person in custody, the same period runs from service of a copy on that person.

The cal­en­dar does not assess grounds for cas­sa­tion review or replace analy­sis of the first-in­stance and ap­pel­late de­ci­sions. In a Kyiv case, counsel should sep­a­rate­ly check the pro­nounce­ment record, elec­tron­ic court records and proof of service if the special branch applies.

Calculation methodology

How the dead­line is de­ter­mined

  1. The user con­firms that the chal­lenged de­ci­sion has been checked against Article 424 of the Crim­i­nal Pro­ce­dure Code.

  2. Use the pro­nounce­ment date or, only for a con­vict­ed person in custody, the date on which the copy was served.

  3. The period starts on the cal­en­dar day after the se­lect­ed event.

  4. Add three cal­en­dar months to the event date; if that day does not exist, use the month's last day.

  5. A Sat­ur­day or Sunday at the end of the period is moved to Monday. Other non­work­ing days are not encoded.

  6. The result is com­pared with today's date in the Europe/Kyiv time zone.

Example

Example for a Kyiv case

The ap­pel­late court pro­nounced its de­ci­sion in a crim­i­nal case from Kyiv on 17 August 2026; the con­vict­ed person is not in custody.

  • Start­ing event: pro­nounce­ment of the ap­pel­late de­ci­sion
  • Event date: 17.08.2026
  • Period: three cal­en­dar months

The first day of the period is 18 August; the pre­lim­i­nary last day for cas­sa­tion is 17 No­vem­ber 2026.

The example does not confirm that this par­tic­u­lar de­ci­sion may be chal­lenged in cas­sa­tion; the de­ci­sion and ap­pli­can­t's stand­ing must be checked.

What to check in the case record

  • The first-in­stance de­ci­sion and the full ap­pel­late de­ci­sion.
  • The ap­pel­late de­ci­sion's pro­nounce­ment date and, if needed, the hearing log or record­ing.
  • A receipt or other proof of service of the copy if the con­vict­ed person is in custody.
  • A doc­u­ment con­firm­ing pro­ce­dur­al status and the au­thor­i­ty of counsel or a rep­re­sen­ta­tive.
  • The cas­sa­tion com­plaint, ar­gu­ments about the ap­pli­ca­tion of law, copies and at­tach­ments under Article 427 of the Crim­i­nal Pro­ce­dure Code.
  • Proof that the com­plaint was sent or handed to an au­tho­rised person on time.

Frequently asked questions

How long is the period for criminal cassation?

The general rule is three cal­en­dar months from pro­nounce­ment of the ap­pel­late de­ci­sion. For a con­vict­ed person in custody, the three months run from service of a copy of that de­ci­sion.

When does the period begin after service of a copy?

Only in the sit­u­a­tion covered by Article 426 of the Crim­i­nal Pro­ce­dure Code: a con­vict­ed person held in custody. Another par­tic­i­pant re­ceiv­ing a copy later does not itself shift the start­ing date.

What if the last day falls on a weekend?

As a general rule under the Crim­i­nal Pro­ce­dure Code, a final non­work­ing day moves to the next working day. The tool handles Sat­ur­day and Sunday au­to­mat­i­cal­ly; check other non­work­ing days sep­a­rate­ly.

Can a cassation complaint be filed after the deadline?

The court decides restora­tion of time on an ap­pli­ca­tion sup­port­ed by ev­i­dence of valid reasons. Martial law alone does not au­to­mat­i­cal­ly restore the dead­line.

Will the Supreme Court necessarily consider the merits of the complaint?

No. Check whether the de­ci­sion is ap­peal­able, the ap­pli­can­t's stand­ing, the com­plaint re­quire­ments and pro­ce­dur­al grounds. A cal­en­dar date does not guar­an­tee that cas­sa­tion pro­ceed­ings will be opened.
