Any decision about when the period will end or where the cardinal will live permanently will be made in agreement with the Vatican, said a statement released on May 15 by the Vatican press office.
The statement did not specifically mention Cardinal O'Brien's sexual misconduct. Instead, it referred to "the same reasons he decided not to participate in the last conclave."
Retired Pope Benedict XVI accepted Cardinal O'Brien's resignation February 25 after the Observer, a British weekly national newspaper, carried a story detailing complaints of three priests and one former priest who alleged Cardinal O'Brien had made homosexual advances toward them.
The cardinal initially denied the allegations but said he would not be in Rome for the conclave to elect a successor to Pope Benedict because he did not want media attention to be on him rather than on the process to elect a new pope.
Less than a week later, however, he issued a public apology for his actions. He said he initially denied the allegations because they were made anonymously.
But, in the March 3 statement, he said, "I wish to take this opportunity to admit that there have been times that my sexual conduct has fallen below the standards expected of me as a priest, archbishop and cardinal."
In early May, Cardinal O'Brien was photographed moving his belongings into a church-owned residence in Dunbar, on the North Sea coast about 30 miles from Edinburgh, where he had served as archbishop since 1985.
