evidence: Having rejected Indonesia’s arguments based on its effectivités, the Court turned to the consideration of the effectivités relied on by Malaysia. As evidence of its effective administration of the islands, Malaysia cited inter alia the measures taken by the North Borneo authorities to regulate and control the collecting of turtle eggs on Ligitan and Sipadan, an activity of some economic significance in the area at the time. It relied on the Turtle Preservation Ordinance of 1917 and maintained that the Ordinance "[had been] applied until the 1950s at least" in the area of the two disputed islands. It further invoked the fact that the authorities of the colony of North Borneo had constructed a lighthouse on Sipadan in 1962 and another on Ligitan in 1963, that those lighthouses still existed and that they had been maintained by Malaysian authorities since its independence. The Court noted that "the activities relied upon by Malaysia . . . [we]re modest in number but . . . they [we]re diverse in character and include[d] legislative, administrative and quasi-judicial acts.
