Former top White House aide I. Lewis "Scooter" Libby was banned Thursday from practicing law in the nation's capital following his perjury conviction in the case of a CIA operative's leaked identity.

The disbarment order of the U.S. Court of Appeals for the District of Columbia had been expected.

"When a member of the bar is convicted of an offense involving moral turpitude, disbarment is mandatory," the appeals court ruled.

Last May, a court panel that oversees lawyer ethics recommended that Libby be stripped of his law license in Washington. The Board on Professional Responsibility then found that Libby's conviction for lying to the FBI about the case of former CIA operative Valerie Plame amounted to "crimes that involve moral turpitude."
