Background

Yaroslav Osadchyy invested through a housing trust fund in a Kyiv flat and utility closet. His contracts required him, within two months after construction was completed, to sign an agreement with the designated building-management company and acceptance certificates for the premises. After he objected to the management agreement, the fund manager terminated his membership for allegedly missing the deadline to sign the certificates, and allocated the flat to another person.

In January 2017, the Kyiv City Court of Appeal held that a notice published on a website was not proper notice of the completion of construction. It annulled the termination and invalidated the third party’s title to the flat. The Higher Specialised Civil and Criminal Court dismissed the fund manager’s cassation appeal in July 2017. Days later, however, it restored the time-limit for the third party’s late cassation appeal without giving reasons. In October 2018, the Supreme Court allowed that appeal, reversed the rulings favorable to Osadchyy, and dismissed his claim.

The Court’s Holding

The European Court of Human Rights unanimously held that Ukraine violated Article 6 § 1 because the reopening and reversal of final rulings in Osadchyy’s favor breached legal certainty and the res judicata principle. Although the cassation court had discretion to restore the filing deadline, it provided no reasons and did not assess whether reopening the case justified interfering with finality.

The reversal was based only on a different assessment of whether the website publication constituted valid notice—an ordinary issue of domestic-law application. The Court found no fundamental judicial error or substantial and compelling circumstances capable of justifying the reopening. It awarded EUR 1,000 for non-pecuniary damage and EUR 500 for Strasbourg costs. It declared the Article 1 of Protocol No. 1 complaint inadmissible and found no need to examine the applicant’s remaining Article 6 complaints.

Key Takeaways

  • A court must give reasons when restoring a missed deadline if that decision may unsettle final judgments.
  • A mere change of view on a routine legal issue does not justify overturning final civil rulings.
  • The violation concerned procedural legal certainty, not a finding that Ukraine unlawfully deprived the applicant of property.

Why It Matters

The judgment reinforces that finality in civil litigation is a core component of the fair-trial guarantee. Domestic procedural discretion over late appeals must be exercised with reasons and with regard to the competing interest in preserving final judgments.

It also distinguishes Article 6 legal-certainty violations from property claims: reversal of a favorable judgment does not automatically establish a violation of Article 1 of Protocol No. 1, particularly where the judgment did not itself confer title and contractual conditions for ownership remained unfulfilled.
