Spanish judge Baltasar Garzon says he won't represent fugitive National Security Agency leaker Edward Snowden.
In a statement Wednesday, Garzon said his legal firm had decided not to take on Snowden's case but gave no explanation.
Snowden, who is charged with violating American espionage laws, is said to be in the transit zone of a Moscow airport. He has asked for asylum from Ecuador.
Snowden sought legal help from Garzon, who represents WikiLeaks founder Julian Assange.
Garzon became famous for indicting former Chilean dictator Augusto Pinochet in 1998, and trying to put him on trial for crimes against humanity. He was suspended from office in Spain for overstepping his powers by starting an investigation into killings committed on behalf of former Spanish dictator Gen. Francisco Franco.
