Practice Relating to Rule 108. Mercenaries
At the CDDH, Cuba stated, with regard to paragraph 2(c) of Article 42 quater of the draft Additional Protocol I (now Article 47), that it “has serious doubts about its objectivity, since in practice it will not be possible to verify whether or not the material compensation is in excess of that paid to combatants of similar rank and functions”.
