Each island has its own high-chief, or ulu-aliki, and several sub-chiefs (alikis). The community council is the Falekaupule (the traditional assembly of elders) or te sina o fenua (literally: "grey-hairs of the land"). In the past, another caste, the priests (tofuga), were also amongst the decision-makers. The ulu-aliki and aliki exercise informal authority at the local level. Ulu-aliki are always chosen based on ancestry. Under the Falekaupule Act (1997), the powers and functions of the Falekaupule are now shared with the pule o kaupule (elected village presidents; one on each atoll).
