The High Court has ruled that Reece O’Brien should have been acquitted of obstructing a Garda during a search of his Dublin home because the prosecution did not formally prove the warrant authorising the search.
The ruling arose from a case stated by District Judge John Hughes following O’Brien’s conviction for obstructing a peace officer under section 19(3) of the Criminal Justice (Public Order) Act 1994.
The District Court had heard that Garda Sheridan entered the property on 17 January 2024 under what he described as a section 26 Misuse of Drugs Act search warrant. He said O’Brien resisted a search of his person, leading to a struggle, pepper spray and restraint. O’Brien disputed that account and alleged that the Garda had been aggressive and used excessive force.
The warrant itself was not produced during the prosecution case. It was only produced after the case had closed.
In her judgment of 30 April 2026, Ms Justice Gearty held that proving the Garda was acting lawfully was part of the prosecution’s case. Because the alleged obstruction occurred during a search inside a constitutionally protected dwelling, the State had to prove the legal authority for both entry and search.
The judge said oral evidence that a Garda “had a warrant” could not replace production of the written warrant where it was available. Without proof of a valid warrant, the prosecution had not established beyond reasonable doubt that the officer was acting in the execution of his duty.
The High Court therefore answered the District Court’s central question by holding that the conviction was not correct. The judgment determines the legal issue in the case stated; any consequential District Court order is not recorded in the judgment itself.
Ms Justice Gearty also expressed the provisional view that O’Brien should receive his costs, subject to further submissions within 14 days.
