A Truth Commission investigating human rights abuses under the nation's military dictatorship says that those it finds guilty of torture could be brought to trial.

A 1979 amnesty law protects civilians and military personnel from liability for politically motivated crimes committed during the 1964-1985 military regime. But commission's coordinator Rosa Cardoso says they could be tried by the Costa Rica-based Inter-American Court of Human Rights.

She notes that "there are no statutes of limitations for crimes committed against humanity." And adds, "Amnesties are not valid under international law."

Unlike Argentina, Chile and Uruguay, Brazil has never punished military officials accused of human rights abuses.
