Al-Qutaji, who was detained in March, says that he and other Iraqi lawyers have been unable to stop abuses because US forces have been given immunity from prosecution.
Former head of the Coalition Provisional Authority, Paul Bremer, dismissed 120 of Iraq's senior judges, 45 of them in Mosul, on the grounds that they were supporters of former Iraqi president Saddam Hussein's regime.
Phil Shiner, of the Birmingham-based law firm, Public Interest Lawyers, is trying to get the cases raised in the British courts. He is working with US lawyers to get them raised there.
"The British public needs to know the full implications of the decision to get into this war," he said.
A US Army spokesman yesterday said he was surprised by the allegations.
The Defense Ministry in London said it had not yet been made aware of the allegations.
