The Penang state government has its own executive council and legislature, but they have relatively limited powers in comparison with those of the Malaysian federal government. According to the Malaysian Federal Constitution, the state may legislate on matters pertaining to Malay customs, land, agriculture and forestry, local government, civil and water works, and state administration, whereas matters that fall under the joint purview of both state and federal authorities include social welfare, wildlife protection and national parks, scholarships, husbandry, town planning, drainage and irrigation, and public health and health regulations.
