The Martens Clause has formed a part of the laws of armed conflict since its first appearance in the preamble to the 1899 Hague Convention (II) with respect to the laws and customs of war on land:
“Until a more complete code of the laws of war is issued, the High Contracting Parties think it right to declare that in cases not included in the Regulations adopted by them, populations and belligerents remain under the protection and empire of the principles of international law, as they result from the usages established between civilized nations, from the laws of humanity and the requirements of the public conscience.”

While such resolutions may have no formal binding effect in themselves, they certainly do represent ‘the dictates of public conscience’ in the 20th century, and come within the ambit of the ‘Martens Clause’ prohibition.”
