The Spanish judge best known for indicting Augusto Pinochet and Osama bin Laden appeared in court Wednesday with the tables turned: This time he was a suspect, accused of overstepping his authority in a huge domestic case involving Spanish civil war atrocities.

Baltasar Garzon made no comment to reporters as he arrived at the Supreme Court in Madrid in a very rare case of a Spanish judge being formally probed in legal proceedings. A handful of supporters cheered Garzon as he went in a side entrance for a closed-door session.
