Mr Justice Séamus Woulfe has testified at the trial of two politicians and two hoteliers accused of breaching a lockdown law in August 2020.
The Supreme Court judge told the court he was satisfied that COVID-19 guidelines were fully complied with at a dinner he attended in the Clifden Station House Hotel.
Justice Woulfe played nine holes with the Oireachtas Golf Society on August 19th, 2020.
He said the first he became aware of a group dinner afterwards when he registered at the clubhouse and paid his fee.
He said he was invited by Senator Paul Coughlan who assured him that one of the four accused, former FF Senator Donie Cassidy, had consulted with authorities.
He said he was told everything was in line with COVID-19 guidelines and he relied upon expressed assurances he received.
When asked if he saw anything that caused him concern, he said, “no.”
Beforehand, Senator Jerry Buttimer said he felt the hotel went “above and beyond”.
Independent TD Noel Grealish, the hotel owner, John Sweeney, and his son, hotel GM James Sweeney, are also accused of organising an event in breach of COVID laws.
