Fresh claims have emerged against a former headmaster of St Edmund's College, who was accused last year of molesting a student repeatedly over two years.
The late Brother Noel Landener served his first stint as a headmaster at St Edmund's between 1960 and 1965, following a long career in the Catholic Christian Brothers order.
He was celebrated in the decades after he left the school, and rose through the ranks of Christian Brothers to become a member of Queensland's provincial council and then a school inspector in the same state, according to his obituary.
He was praised for driving up student numbers, cultivating "self-discipline", and having a "talent for organisation, abundant energy, and a clear view of the school he wanted St Edmund's to become".
One of the school's six houses was named in his honour.
But, following his death in 1982, disturbing allegations began to emerge about his five years in Canberra.
The first public abuse claim involving Landener emerged in the early 2000s.
The victim brought civil action against the Christian Brothers, alleging he had been fondled in the school's sick bay by Brother Landener.
The former Bishop of Canberra and Goulburn Pat Power had investigated the claim and, upon finding independent corroboration, urged the school to change the house name from "Landener House".
Now a new complainant has emerged.
In a civil case filed last year by Porter's Lawyers, it was alleged that Brother Landener repeatedly molested the boy in 1965 and 1966.
The headmaster allegedly massaged, rubbed and touched the boy's back, and indecently assaulted him repeatedly.
The claim, lodged in the ACT Supreme Court last year, alleged the abuse caused psychiatric and psychological trauma to the child.
The victim sued the estates of former members of the Christian Brothers provincial council, as well as the Catholic order itself.
They initially defended the claim, denying the allegations of the sexual assault and that the provincial council or Christian Brothers failed in its duty of care to the boy.
The case was later settled out of court, which does not necessarily mean Christian Brothers accepted the allegations.
Court documents setting out the former student's claim alleged that provincial council members and the order were vicariously liable for the abuse.
It said they failed to properly supervise the headmaster, allowed him to have unsupervised contact with the victim, and did not properly "instruct Landener not to sexually assault the plaintiff or children from the school".
It was alleged the Christian Brothers order did not "institute and maintain a system of mandatory reporting of child abuse" and did not take procedures to ensure he was "not likely to abuse students".
"The conduct of the [defendants] ... fell so far short of acceptable standards as to represent a contumelious disregard for the plaintiff's rights and a violation of his rights to personal and bodily integrity," the claim stated.
In a statement, Christian Brothers Oceania said its approach to civil cases was "victim focused".
The order said they tried to resolve court cases quickly, while recognising that "the settlement of civil claims do not constitute criminal findings".
"To any person who has suffered abuse at any of our facilities, the Christian Brothers Oceania extends our unreserved apology," the statement read.
"Our approach since the early 1990s to these matters has been to encourage those with complaints to come forward and our response mirrors the now-recommended approach of the Royal Commission, namely personal apology, counselling and monetary payments."
The Christian Brothers has encouraged anyone who has suffered abuse at its facilities to contact its professional standards office in Melbourne on (03) 8359 0134.
