In Nigeria, public corporations are established by an act of parliament. This means that they are created through a legal process that involves passing a bill through the National Assembly, which is the legislative body of the government. The bill is then signed into law by the President, and the public corporation is officially established. This process ensures that the creation of public corporations is subject to oversight and accountability, and that they operate in accordance with the laws and regulations of the country. Public corporations established through other means, such as executive orders or military decrees, would not have the same level of legitimacy or accountability.
