An appeals court has overturned the conviction of Colombian ex-President Álvaro Uribe for bribery and witness tampering. Uribe, 73, has denied any wrongdoing. He was sentenced to 12 years in house arrest in August following a nearly six-month trial in which prosecutors presented evidence that he attempted to influence witnesses who accused the law-and-order leader of having links to a paramilitary group in the 1990s. In the appeal, his lawyers questioned the validity of the evidence and argued that the former president’s responsibility was not “unequivocally” proven. Prosecutors can appeal Tuesday’s ruling to Colombia’s Supreme Court.
