Bill Kenneally (67), formerly of Summerville Avenue, Waterford city, is charged with committing the offences in Waterford 20 years ago.
The three complainants are now aged in their 40s.
A book of evidence was served on Kenneally, a former basketball coach, last month, and he appeared in Waterford district court yesterday.
Solicitor Matthew Byrne said he had been instructed to take on the case from Patrick Newell, who had been representing the accused.
Mr Byrne asked Judge David Staunton if the legal aid originally granted to Bill Kenneally could be transferred to him and said that he had spoken to Mr Newell and there was no objection.
Judge Staunton agreed to transfer the legal aid, and also allowed for a senior counsel and junior counsel to be appointed to the accused, after Mr Byrne said the charges were “serious matters”.
The judge sent Bill Kenneally forward for trial, on 99 charges contained in the book of evidence, to the current sittings of Waterford Circuit Criminal Court.
He advised the accused that if he intended to rely on alibi evidence, he had 14 days to inform the prosecution.
Bill Kenneally was remanded on continuing bail on his own bond of €500.
