Administrative law is a branch of public law primarily concerned with the powers and procedures of governmental administrative agencies and their relationship with the public. This field investigates the laws, regulations, and rules created by these agencies, how they are administered and regulated at various levels (federal, state, local), and the legal framework governing their interactions with individuals and entities. Its significance lies in ensuring governmental accountability, fairness, lawfulness, and the protection of citizens from potential abuses of power by requiring agencies to act within their delegated authority and adhere to legal principles.
