Colombia’s Constitutional Court held in 1995 that the prohibitions contained in Article 4(2) of the 1977 Additional Protocol II were consistent with the Constitution, since they were not only in harmony with the principles and values of the Constitution, but also practically reproduced specific constitutional provisions.
