The document discusses the territorial dispute between Cambodia and Thailand over the Temple of Preah Vihear, which arose from conflicting maps produced after treaties established a watershed boundary in the early 20th century. The International Court of Justice ruled in favor of Cambodia, citing acquiescence on Thailand's part for failing to contest the boundary maps in a timely manner, thereby recognizing Cambodia's sovereignty over the temple. The ruling emphasized that Thailand's responsibility to inspect the maps negated any claims of error regarding the boundary's designation.
