A Colombian court has ruled that a framework drawn up for peace talks between the government and FARC rebels is constitutional.
The Legal Framework for Peace, approved by Congress last year, has been criticised by the opposition and human rights groups as a “backdoor amnesty” for horrific crimes committed by FARC since the rebel group formed in 1964.
The legal green light prompted President Juan Manuel Santos to announce Bogota would begin discussions with the FARC counterpart the ELN.
His government argue that without the prospect of immunity FARC would simply not come to the table.
Those opposed to the law say FARC members responsible for dreadful crimes will benefit from soft prison sentences or avoid punishment completely.
More than 200,000 people have died since FARC began its violent campaign against the government.
