Practice Relating to Rule 6. Civilians’ Loss of Protection from Attack
Section C. Situations of doubt as to the character of a person
Colombia’s Instructors’ Manual (1999) states: “In case of doubt whether a person is civilian or not, that person must be considered to be civilian.”
Colombia’s Operational Law Manual (2009) states:
According to Article 50 of the  Additional Protocol I, whenever there is doubt about the status of a person, that person will be considered as a civilian. In this sense, if there is a doubt about the persons’ membership of an organized armed group or about their direct participation in hostilities, it must also be presumed that the person is a civilian and any attack should therefore be avoided.
