Prominent judge Baltasar Garzon has been found not guilty of going beyond his powers when trying to prosecute crimes carried out during the rule of General Franco.
Garzon was accused by two right-wing groups in Spain of violating an amnesty law that covers this period.
Seen by supporters on the left as a champion of human rights, Garzon also helped bring about the arrest of former Chilean dictator Augusto Pinochet.
However, the right sees Garzon as a publicity-seeker.
The high-profile judge has been banned from practicing law in Spain for 11 years after another conviction for wire-tapping, which he says he will appeal.
