Hyland v The Commissioner of An Garda Siochana (Approved) [2025] IESC 43 (06 November 2025)

Hyland v The Commissioner of An Garda Siochana (Approved) [2025] IESC 43 (06 November 2025)

There is no lawful basis for the use of material seized under a criminal search warrant for the purposes of internal Garda disciplinary proceedings once the criminal investigation has concluded without prosecution, as neither s. 7 of the Child Trafficking and Pornography Act 1998 nor s. 9 of the Criminal Law Act 1976 authorise such use, and no implied statutory or common law power can be read in to permit it. Any such use would constitute a disproportionate interference with the constitutional right to privacy, absent express statutory authority or independent judicial authorisation.
