A High Court judge has mandated Northern Ireland Secretary Hilary Benn to initiate a public inquiry into the 1997 murder of GAA official Sean Brown. The ruling follows findings that the UK government failed to meet its human rights obligations regarding state collusion in the case. Sean Brown, who was killed by a loyalist gang, has had no arrests related to his murder despite extensive connections to state agents. The judge emphasized the need for a thorough investigation to uncover the truth behind the killing.
