And it would be appear there would be nothing to prevent him doing so, as British passport holders can visit the Island at any time.
Newall (41) murdered his parents, Nicholas and Elizabeth, on 10 October 1987 when he bludgeoned them to death at their home at Clos de l’Atlantique in St Brelade.
His brother Mark, an international banker, was convicted of assisting in concealing the bodies.
The crime went unsolved for five years until the former Royal Greenjackets officer confessed to his uncle in Scotland.
The confession was secretly tape-recorded.
He was arrested and taken to Gibraltar, where he fought extradition to Jersey for well over a year.
When he was returned, he took police officers to woods near Grève de Lecq where the bodies were buried.
He was eventually jailed in 1994 and Mark Newall spent 20 months in prison for the part he played.
It was reported in the Mail on Sunday yesterday that Roderick Newall is due to be released from prison in August after serving 12 years.
