The Spanish judge celebrated for pursuing international human rights cases was convicted of overstepping his jurisdiction in a domestic corruption probe Thursday and barred from the bench for 11 years, completing a spectacular fall from grace for one of Spain's most prominent people.

A seven-judge panel of the Supreme Court convicted Baltasar Garzon unanimously. He is 56, so the punishment could effectively end his career in Spain.

Garzon acted arbitrarily in ordering jailhouse wiretaps of detainees talking to their lawyers, the court said, adding that his actions "these days are only found in totalitarian regimes."

Ironically, Garzon is best known for indicting a totalitarian ruler, former Chilean dictator Augusto Pinochet, in 1998, and trying to put him on trial in Madrid for crimes against humanity.

Garzon acted under the principle of universal jurisdiction — the idea that some crimes are so heinous they can be prosecuted anywhere. He and colleagues at the National Court went on to champion this doctrine and try to apply it to abuses in such far-flung places as Rwanda and Tibet. Garzon also indicted terror mastermind Osama bin Laden in 2003 over the Sept. 11 attacks in the United States.
