A federal judge has ruled that former Defense Secretary Donald H. Rumsfeld can be sued personally for damages by a former U.S. military contractor who says he was tortured during a nine-month imprisonment in Iraq.

The lawsuit lays out a dramatic tale of the disappearance of the then-civilian contractor, an Army veteran in his 50s whose identity is being withheld from court filings for fear of retaliation. Attorneys for the man, who speaks five languages and worked as a translator for Marines collecting intelligence in Iraq, say he was preparing to come home to the United States on annual leave when he was abducted by the U.S. military and held without justification while his family knew nothing about his whereabouts or even whether he was still alive.

The government says he was suspected of helping pass classified information to the enemy and helping anti-coalition forces get into Iraq. But he was never charged with a crime, and he says he never broke the law and was risking his life to help his country.
