📂 Case Details
Case Title: MILITUS-PL SP. Z O.O. v UKRINMASH
Case No.: 824/56/26
Court: Kyiv Court of Appeal
Date: 27 July 2026
Case Category: International Commercial Arbitration
Subject Matter: Setting Aside Arbitral Awards
Sub-Subject: Commencement of Set-Aside Proceedings
Arbitral Institution: International Commercial Arbitration Court at the Ukrainian Chamber of Commerce and Industry (ICAC)
ICAC Case No.: 226/2025
ICAC Award Date: 20 March 2026
Background of the Dispute
The proceedings arise from an international commercial arbitration between Ukrinmash, a subsidiary of Ukraine’s state-owned defence company Ukrspetsexport, and Militus-PL sp. z o.o., a Polish company.
The underlying ICAC arbitration concerned Ukrinmash’s claims against Militus-PL for the recovery of penalties and damages.
ICAC rendered its award in Case No. 226/2025 on 20 March 2026.
On 23 June 2026, Militus-PL applied to the Kyiv Court of Appeal seeking to set aside the ICAC award.
The Court’s Decision
The Kyiv Court of Appeal reviewed the application against the procedural requirements governing challenges to international commercial arbitration awards.
The Court found that Militus-PL’s application complied with the form and content requirements of Article 455 of the Civil Procedure Code of Ukraine and had been submitted within the time limits prescribed by Article 454.
Finding no procedural obstacle to consideration of the challenge, the Court opened set-aside proceedings on 27 July 2026.
The Court ordered that copies of the application and supporting materials be sent to the participants and gave them 20 days from receipt to submit objections or explanations and supporting evidence.
The order is not subject to appeal.
Why This Decision Matters
The ruling provides another example of the supervisory role exercised by Ukrainian courts over international commercial arbitration awards made in Ukraine.
At this stage, the Kyiv Court of Appeal has not set aside the ICAC award and has not determined whether Militus-PL has established any statutory ground for doing so. The decision is procedural: the application passed the initial admissibility review and may now proceed to substantive consideration.
The case is particularly relevant because the underlying dispute combines international arbitration, defence-sector commerce and a Ukraine–Poland cross-border relationship.
It also demonstrates the procedural distinction between an application being accepted for consideration and the much more significant subsequent question of whether the arbitral award satisfies the limited statutory grounds for setting aside.
Lions Lawyers’ Analysis
For foreign parties involved in Ukrainian-seated arbitration, the decision illustrates the first stage of the post-award challenge process.
Militus-PL successfully passed the procedural threshold. Its application was filed within the applicable period and complied with the formal requirements of Ukrainian procedural law. This allows the company to proceed with its challenge, but it says nothing yet about the strength of the substantive grounds advanced against the award.
This distinction is important. Set-aside proceedings are not an ordinary appeal against an arbitral tribunal’s decision. The role of the Ukrainian court is not simply to reconsider the commercial dispute or substitute its assessment for that of the arbitral tribunal. The challenge must ultimately be assessed within the statutory framework governing the setting aside of international commercial arbitration awards.
The case also has a significant cross-border commercial dimension. A Polish company is challenging an ICAC award arising from a dispute with a Ukrainian state-owned defence-sector enterprise. For international businesses contracting with Ukrainian state entities, it demonstrates why dispute-resolution planning should cover not only arbitration itself but also potential post-award challenges, enforcement proceedings and the interaction between arbitral and national court procedures.
The substantive outcome of Militus-PL’s challenge will therefore be considerably more important than this initial procedural order and should be monitored separately.
