At the CDDH, Indonesia proposed deleting paragraph 1(c) of Article 35 of the draft Additional Protocol I (now Article 37). 
Indonesia, Proposal of amendment to Article 35 of draft Additional Protocol I submitted to the CDDH, Official Records, Vol. III, CDDH/III/232, 25 February 1975, p. 164.
This proposal was the expression of the fear that paragraph 1(c) could be misused to punish combatants who would otherwise be entitled to the status of prisoner of war. However, Indonesia finally agreed upon paragraph 1(c) of Article 35 of the draft Additional Protocol I (now Article 37) following the same reasoning as the one of Viet Nam stated below.
