Aubin has appeared in court on three charges of sexually assaulting boys at a former children's home on Jersey. He was remanded in custody by magistrates over the alleged abuse at Haut de la Garenne.
He is accused of indecent assault of a seven year old and 13 year old, and serious sexual assault of an eight year old, all between 1977 and 1980.
Aubin's case has now been sent to the Royal Court, although a trial date has not been set.
Two other men charged with alleged abuse have yet to enter pleas.
Gordon Wateridge is charged with three offenses of indecent assault on girls under the age of 16, between 1969 and 1979 at Haut de la Garenne.
Claude Donnelly is charged with raping and sexually assaulting a 12-year-old girl on Jersey between 1971 and 1974.
Donnelly’s arrest is part of the wider inquiry into child abuse on Jersey.
