Gardaí did not have a general power to enter the flat of a man and arrest him for breach of the peace after they had been called to a disturbance at his home, the High Court has ruled.

Mr Justice Charles Meenan said, while gardai had a power to do so under the criminal law, they did not invoke that power when they entered Philip O’Brien’s flat in Marino Apartments, Tralee, Co Kerry.

They did not therefore enjoy a common law power to enter the dwelling to arrest him for breach of the peace, contrary to common law, he found.

The judge reversed a conviction for obstruction imposed on Mr O’Brien arising out of the incident.

On May 26th, 2017, when gardaí were called to a disturbance at Mr O’Brien’s home, they found a living room window had been broken and a block of knives lay on the ground outside the window.

A garda, along with three colleagues, could see Mr O’Brien in an agitated state through the broken window and it appeared the apartment had been damaged with several items scattered around the room.

An officer tried to speak with him through the open window and then gardaí went to the front door where they found Mr O’Brien still agitated.

Garda John Coffey said, while trying to speak with him at the doorway, Mr O’Brien spat in his face.

Violently resisted Garda Coffey and his colleagues then entered the apartment where Mr O’Brien retreated to the kitchen.

Gardaí could see a knife on the floor and Garda Coffey said the defendant violently resisted. He was restrained and arrested for breach of the peace.

He was later charged with obstructing a garda and common assault.

At his District Court hearing, his lawyer argued he had no case to answer as gardaí had no right under common law to enter his home to arrest him for breach of the peace.

This was, the lawyer said, a breach of the constitutional right to inviolability of the home.

The District Judge rejected the submission and convicted him of obstruction.

Mr O’Brien then brought an appeal, by way of case stated to the High Court, asking the court to determine whether gardaí had such a common law power. The DPP opposed the appeal.

Mr Justice Meenan said Section 6 of the Criminal Law Act 1997 empowers gardaí to enter a home without a warrant for an arrestable offence in certain circumstances including where they have cause to believe a person will obstruct the course of justice.

In this case, that power was not relied upon and therefore did not apply.

Any restriction on the constitutional right that may be permitted by law must be minimal and, except where life is in imminent danger, the restrictions on that right are set out in the 1997 Act.
