Administrative law is a body of law that governs the activities of government agencies. It is designed to protect the rights of individuals and businesses, ensure that government agencies act fairly and equitably, and regulate the activities of government agencies.

A rule is a general statement of policy that is issued by an agency and is binding on all persons. An order is a specific directive to a particular person or entity that is issued by an agency or a court and is only binding on the person or entity to whom it is directed.

An agency can promulgate a rule through notice and comment, negotiated rulemaking, or informal rulemaking. Notice and comment is the most common method of rulemaking. It involves publishing a proposed rule in the Federal Register and allowing the public to comment on the proposed rule. Negotiated rulemaking is a process in which an agency works with interested parties to develop a rule. Informal rulemaking is a process in which an agency adopts a rule without providing notice and comment or engaging in negotiated rulemaking.

The standard of review that a court uses when reviewing an agency action depends on the nature of the action. For most agency actions, the court will use the arbitrary and capricious standard of review. This standard requires the court to uphold the agency action if it is not arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law. For some agency actions, the court will use the substantial evidence standard of review. This standard requires the court to uphold the agency action if it is supported by substantial evidence in the record. For a few agency actions, the court will use the de novo standard of review. This standard requires the court to make its own independent determination of the facts and the law.

When a court finds that an agency action is unlawful, it can order a variety of remedies. These remedies include injunctions, declaratory judgments, and mandamus. An injunction is a court order that prohibits an agency from taking a particular action. A declaratory judgment is a court order that declares the rights and obligations of the parties in a case. Mandamus is a court order that compels an agency to take a particular action.

The Administrative Procedure Act (APA) is a federal law that governs the procedures that agencies must follow when they take certain actions. These actions include rulemaking, adjudication, and licensing.

The purpose of the APA is to ensure that agencies act fairly and equitably, protect the rights of individuals and businesses, and promote transparency and accountability in government.

The key provisions of the APA include the requirement that agencies provide notice and comment before they adopt rules, the requirement that agencies hold hearings before they take adjudicatory actions, and the requirement that agencies issue written decisions that explain the basis for their actions.

A formal adjudication is conducted in accordance with the rules of evidence, by an administrative law judge, and is subject to judicial review. An informal adjudication is not conducted in accordance with the rules of evidence, is conducted by an agency official, and is not subject to judicial review.

The process for obtaining judicial review of an agency action is to file a petition for review with the appropriate court.

The grounds for judicial review of an agency action include that the agency action was arbitrary and capricious, not supported by substantial evidence, or in violation of the Constitution or a statute.

The scope of judicial review of an agency action includes the court's ability to review both the agency's record and its legal conclusions.

The doctrine of exhaustion of administrative remedies requires a party to exhaust all administrative remedies before seeking judicial review of an agency action.

The doctrine of primary jurisdiction requires a court to defer to an agency's interpretation of its own regulations.

The doctrine of ripeness requires a court to consider whether an issue is ripe for judicial review.
