At the CDDH, Australia proposed an amendment to Article 20 of the draft Additional Protocol I which read: “Measures in the nature of reprisals against the persons and objects protected by this Part are prohibited.” 
Australia, New proposal concerning Article 20 of draft Additional Protocol I submitted to the CDDH, Official Records, Vol. III, CDDH/II/214, 13 February 1975, p. 97.
However, the Australian delegation noted: “The law concerning reprisals was far from settled and it might be found not to be applicable to peoples fighting wars of self-determination to which draft [Additional Protocol I] had now been extended.”
