The conviction of an Amazon rancher for ordering the killing of an American nun and rain forest activist was upheld by a state court on Tuesday.
A court in Para state ruled that Regivaldo Galvao must serve his 30-year sentence, though he can still appeal that ruling.
Galvao turned himself into police a few hours after the ruling, his lawyer, Janio Siqueira, told the Globo news website.
A jury last year found Galvao guilty of ordering the 2005 shooting death of Dorothy Stang. But he was quickly freed on appeal.
Stang worked for three decades to preserve the rain forest and defend poor settlers' land rights.
Prosecutors said Galvao and another rancher ordered her killing because she was blocking them from illegally obtaining a parcel of land.
