This judgment, *Kolesnyk and Smelnytskyy v. Ukraine*, concerns the compatibility of pre-trial detention with Article 5 § 3 of the European Convention on Human Rights during the ongoing state of martial law in Ukraine. The applicants, charged with national security offences—specifically treason and the unauthorized dissemination of military information—challenged the necessity and length of their detention, as well as the denial of bail. The European Court of Human Rights (ECtHR) examined whether the domestic courts provided “relevant and sufficient” reasons for continued detention and whether the proceedings were conducted with the required “special diligence.” Ultimately, the Court ruled that there was no violation of Article 5 § 3, emphasizing the unprecedented wartime context and the specific security risks involved. The decision confirms that while detention must be justified, the extraordinary circumstances of Russia’s full-scale invasion allow for a margin of appreciation in how justice is administered in frontline regions.
### Structure and Main Provisions
The decision is structured into three primary segments:
1. **Facts and Legal Framework:** It details the arrest of the applicants in Kharkiv, the subsequent reclassification of their charges from unauthorized dissemination of information to treason, and the application of the “Wartime Detention Clause” and the “Exceptions to Mandatory Bail Clause” of the Ukrainian Code of Criminal Procedure.
2. **Admissibility:** The Court rejected the applicants’ complaint under Article 5 § 1 regarding the “reasonableness of suspicion,” finding the reclassification of charges to be a standard investigative evolution rather than an act of bad faith.
3. **Merits (Article 5 § 3):** The Court assessed the necessity of detention. It analyzed the interaction between domestic law and Convention standards, specifically referencing the June 2024 Constitutional Court of Ukraine decision, which clarified that wartime detention provisions do not mandate automatic detention but allow for judicial discretion.
Compared to previous jurisprudence (such as *Grubnyk v. Ukraine*), this decision clarifies that the current wartime legislative framework does not create a system of “mandatory detention” that would inherently violate the Convention, provided that domestic courts retain the power to assess individual risks and the possibility of bail.
### Key Provisions for Legal Practice
* **Judicial Discretion in Wartime:** The most critical takeaway is the Court’s affirmation that the “Wartime Detention Clause” is not a blanket authorization for detention. Courts must still perform a substantive assessment of risks (absconding, influencing witnesses, reoffending) and retain the authority to set bail if the circumstances warrant it.
* **Contextual “Special Diligence”:** The Court explicitly linked the “special diligence” requirement to the wartime context. It recognized that in regions near the frontline, the administration of justice faces extreme challenges. Consequently, the Court will be more deferential to the state’s procedural pace unless the applicant can demonstrate specific, inordinate delays attributable to the authorities.
* **Sufficiency of Reasoning:** The judgment establishes that while detention orders must be reasoned, “succinct” reasoning that relies on previously established facts is acceptable, provided the underlying justification for the detention (the specific risks to national security) remains valid and has been clearly articulated in earlier proceedings.
* **Reclassification of Charges:** The Court reaffirmed that the reclassification of charges during the early stages of an investigation is not, in itself, a violation of the Convention, provided there are objective elements supporting the new, more serious charges.
