TOKYO -- Prayuth Chan-ocha has resumed his official duties as Thailand's prime minister after the country's top court ruled last month that he had not reached his eight-year term limit. After surviving the legal challenge from the opposition, Prayuth threw himself into dealing with devastating floods and a nursery massacre in northeastern Thailand. But the real challenge lurks in a limited-time clause in the constitution that could unseat him or his military-backed successor from office when it expires.
