The suit to be lodged on Monday names Pell, the trustees of Nazareth House, (formerly St Joseph's), the State of Victoria and the Catholic Archdiocese of Melbourne.

The 50-year-old man was a resident in St Joseph's Boys Home in Ballarat from February 1974 to 1978 and says he was abused by Pell during that period.

He was a complainant against Pell in a second trial over allegations Pell indecently assaulted boys in Ballarat in the 1970s. The case was abandoned by prosecutors after a court deemed vital evidence inadmissible; with the man saying he was left devastated by the decision.

"It took a lot of courage and soul searching to be prepared to tell my story, accusing one of the most senior Catholics in the world of serious criminal offences, and eventually I was ready to have my day in court," he told the Herald Sun.

"But when I was told they had withdrawn the case I felt empty, and that an injustice had occurred."

The man's lawyer Lee Flanagan said at least three other witnesses would testify they suffered similar abuse at the hands of the cardinal.

"There was a fourth witness, but he died after charges were laid against Pell. We may seek to tender his statement into evidence in this case," Mr Flanagan told the paper.

A Melbourne jury in December found Pell guilty of five charges of abuse against two choirboys in the 1990s but the verdict was only made public on February 26 after months of procedural secrecy and the abandonment of the second trial.
