Questione giuridica chiave
Whether the use of anonymous witness M.'s statements violated the confrontation right under Article 6 ECHR.
Decisione estratta
No violation: M.'s statements were not the sole or decisive evidence, direct confrontation was objectively impossible, and the authorities offered compensating measures such as access to the protocol and written questions.
Motivazione estratta
The Court held that confrontation may be restricted for overriding interests or objective impossibility if the defense rights are otherwise compensated. Here the witness refused confrontation for safety reasons and later disappeared; the statements were only one element in a broader chain of evidence.
