Background
Cafer Tekin İpek was the former majority shareholder of eighteen companies grouped under the holding company Koza İpek A.Ş., which operated television channels and newspapers in Turkey. Between 2014 and 2016, several official bodies — including the Financial Crimes Investigation Board (MASAK), the Anti-Smuggling and Organised Crime Department (KOM), and the Capital Markets Board (SPK) — issued reports alleging suspicious financial transactions, money laundering, fraudulent book-keeping, unlawful profit distributions, and high-value donations inconsistent with ordinary commercial practice. A separate KOM report in March 2016 alleged that the holding company’s media outlets had broadcast content aligned with the FETÖ/PDY, an organisation designated by Turkish authorities as a terrorist organisation.
On 24 April 2016 İpek’s home was searched and he was taken into police custody. On 25 April 2016 the Ankara 2nd Magistrate’s Court ordered his pre-trial detention on charges of abuse of trust in a service relationship and membership of the FETÖ/PDY armed terrorist organisation, citing the financial investigation reports, the nature of the offences as “catalogue offences” under Article 100 § 3 of the Code of Criminal Procedure, and a risk of absconding. His detention was extended on multiple occasions on broadly similar grounds. He was ultimately convicted on 9 January 2020, with the conviction for abuse of trust becoming final on 27 April 2021; the FETÖ/PDY charge remained pending before the Court of Cassation at the time of the Strasbourg judgment.
İpek applied to the Constitutional Court in May and July 2016 complaining of breaches of Article 5 of the Convention. The Constitutional Court declared both applications inadmissible as manifestly ill-founded in September 2018, in part relying on evidence that İpek had used ByLock, an encrypted messaging application — evidence that was subsequently shown, by an expert report dated 30 July 2019, to have been attributable to a co-accused rather than to İpek himself. He then brought proceedings before the European Court of Human Rights.
The Court’s Holding
The Court unanimously held that there had been a violation of Article 5 § 3 of the Convention due to the absence of sufficient grounds for ordering and maintaining İpek’s pre-trial detention. While the Court accepted that the detailed financial reports from SPK, MASAK, and KOM provided an adequate factual basis for an initial reasonable suspicion of abuse of trust in a service relationship — satisfying Article 5 § 1(c) and rendering that complaint manifestly ill-founded — the domestic courts’ justifications for detention fell short of the individualised assessment required by Article 5 § 3. The detention lasted three years, eight months, and fifteen days.
The Court found that the magistrates’ courts had relied in a stereotyped and formulaic manner on the statutory “catalogue offence” presumption and on abstract recitations of the risks of absconding and evidence-tampering, without applying those grounds to the specific facts of İpek’s situation. Citing its established case-law — including Tuncer Bakırhan v. Turkey and Şık v. Turkey — the Court reiterated that a statutory presumption created by the catalogue-offence provision cannot substitute for a case-specific demonstration that detention is justified, and that continued reliance on boilerplate grounds is especially inadequate where detention is prolonged. The Court also rejected Turkey’s Article 15 derogation argument, finding, consistent with prior cases such as Baş v. Turkey, that the derogation could not justify the measures complained of given the duration of the detention.
The Court declined to examine separately whether the length of detention independently violated Article 5 § 3, having already found a violation on grounds of insufficient justification. It likewise did not reach the Article 5 § 4 complaint, having subsumed it within the Article 5 § 3 analysis. It awarded İpek €3,500 in non-pecuniary damages and €500 in costs, rejecting his €100,000 pecuniary damage claim for lack of a causal link to the violation found.
Key Takeaways
- Reasonable suspicion at the point of initial detention — established here by detailed financial investigation reports — is assessed only on evidence available at the time of the detention order; material added to the file afterwards (such as the ByLock data) is irrelevant to that assessment.
- Turkey’s “catalogue offence” provision (Article 100 § 3 CCP) creates a statutory presumption favouring detention but cannot replace the obligation to demonstrate, by reference to concrete and individualised facts, that detention is warranted in the particular case.
- Formulaic invocations of flight risk and evidence-tampering risk may suffice at early stages of proceedings but are constitutionally insufficient to sustain detention for nearly four years; courts must provide genuinely individualised reasoning as time passes.
- Turkey’s Article 15 derogation, notified in the wake of the July 2016 coup attempt, did not excuse the Convention violation where the detention period was lengthy and the domestic justifications were inadequate.
Why It Matters
This judgment is one of a substantial line of Strasbourg decisions condemning Turkish pre-trial detention practices in post-2016 cases linked to the FETÖ/PDY designation and related financial prosecutions. By reaffirming that catalogue-offence presumptions and boilerplate risk assessments cannot sustain prolonged detention, the Court underlines that Article 5 § 3 imposes a substantive, ongoing obligation on national courts to reassess and individually justify continued remand — an obligation that does not diminish as proceedings drag on, but intensifies.
The case also carries a cautionary note on the use of digital evidence: the Constitutional Court’s reliance on ByLock attribution data that was later proved incorrect illustrates the risks of basing detention justifications on technical evidence that has not been thoroughly verified. For practitioners advising clients detained on terrorism-adjacent charges in jurisdictions with emergency derogations, the judgment reinforces that derogations under Article 15 are not a blanket shield against scrutiny of detention length and reasoning.
