Director of Public Prosecutions v Smyth (Approved) [2024] IESC 22 (17 June 2024)

The Supreme Court held that the mobile telephony traffic and location data was obtained in breach of the Charter, but its admissibility is governed by the JC test under Irish law. The breach was not deliberate or conscious, but arose from subsequent legal developments. Applying the JC test, the evidence was properly admitted as there was no deliberate or conscious violation of rights, and the balance of interests weighed decisively in favour of admissibility. The Supreme Court could and should apply the JC test itself without remitting for retrial.

Procedural Posture

Criminal Appeal / Supreme Court Judgment on Appeal

Legal Issues

  1. 1 Whether mobile telephony traffic and location data retained and accessed under the Communications (Retention of Data) Act 2011, subsequently found incompatible with EU law, is admissible in a criminal prosecution
  2. 2 Whether the breach involved a violation of the Charter of Fundamental Rights of the European Union or a lesser illegality
  3. 3 What test governs admissibility of such evidence under Irish law (JC test or otherwise)

Ratio Decidendi

The Supreme Court held that the mobile telephony traffic and location data was obtained in breach of the Charter, but its admissibility is governed by the JC test under Irish law. The breach was not deliberate or conscious, but arose from subsequent legal developments. Applying the JC test, the evidence was properly admitted as there was no deliberate or conscious violation of rights, and the balance of interests weighed decisively in favour of admissibility. The Supreme Court could and should apply the JC test itself without remitting for retrial.
