行政法, or administrative law, is a branch of law that governs the activities of administrative agencies of government. It involves the rules and regulations that these agencies create and enforce, ensuring they operate within the law. This area of law helps protect citizens' rights by providing a framework for challenging government actions. Administrative law also includes the procedures for how agencies make decisions, issue permits, and enforce regulations. It ensures transparency and accountability in government actions, allowing individuals to seek redress if they believe their rights have been violated by an agency's decision or action.
