Leonard Watters is accused of knowingly making a false report to gardaí, on two occasions, that the pop music mogul sexually assaulted him in top Dublin night-spot Krystle.
Watters, aged 24, appeared at Dublin District Court, where he was granted continuing bail until November 2.
Detective Inspector Michael Cryan told the court Watters said “nothing to say” when charged with the second offence before the hearing.
“The allegation is that Mr Watters made two statements to An Garda Síochána alleging he was sexually assaulted by Louis Walsh in a Dublin nightclub,” said Mr Cryan.
Penalties for the alleged offences, which are under section 12 of the Criminal Law Act, range from a €500 fine to five years in prison.
The first statement was made at Harcourt Terrace Garda Station in Dublin city centre on June 20, and the second was given to gardaí at Watters’s home address in Navan, Co Meath, on June 28 — the day before he was charged and first taken to court.
Dressed in a black V-neck jumper, white shirt and black trousers, Watters made no comment during the short hearing.
In an application for legal aid, Watters’s solicitor Cahir O’Higgins said that his client was a father of two living on disability benefit of €188 a week who paid out €30 a week in rent.
Judge Cormac Dunne granted an application for the disclosure of interview notes held by investigators and CCTV footage of Krystle nightclub and the environs of the celebrity spot on Harcourt Street, which is connected to the Russell Court Hotel.
However, he refused an application that the court order the Mater Hospital in Dublin to hand over medical notes from when Watters was examined after he alleged the incident took place.
Judge Dunne told Mr O’Higgins that the defence team should get the report themselves.
Walsh’s first work in television was in the Irish version of Popstars in 2001. In 2004, he was named as a judge on X Factor and he is the only remaining member of the original panel.
He has managed a number of groups, including Boyzone and Westlife.
