Former staff at St William's school in North Yorkshire say they believe that some of the allegations of abuse are fictitious.
Almost 200 claims have been lodged against the Catholic Diocese of Middlesbrough and the De La Salle Catholic Order of brothers.
James Carragher, the school principal was convicted in two separate trials for abusing boys in his care and jailed for a total of 21 years.
Since Carragher's conviction other staff at the school have been named in abuse claims. One of them was Noel Hartnett, the former Vice Principal.
in 2004 he was charged with three counts of physical abuse, and acquitted of every one of them.
He claims some of those lodging claims are trying to capitalise on the situation. "I've often thought," he says, "what it must have been like for some of them who were particularly vulnerable.
"To be threatened with dire consequences if they ever made disclosure, what that would have done to them. So I do feel very strongly for those who are genuine victims. But i'm absolutely appalled at those who are coming forward relying on this man's predatory activity."
