Law
Law is a system of authority, institutions, procedures, rights, duties, interpretation, and remedies. Study not only what a rule says, but who can apply it, which sources control, how facts enter the process, how competing arguments are evaluated, and what legal consequences follow.
Choose a body of law, an institution, or the methods used to reason from authority.
These planned branches are navigation categories, not mutually exclusive boxes. A criminal case can raise constitutional questions, administrative decisions can reach appellate courts, and legal method follows every branch into statutes, cases, evidence, interpretation, and procedure.
A teaching sequence, not a promise that real disputes proceed in a clean line.
Track the direction of appeal separately from the direction of precedent.
Appeals usually move upward. Controlling precedent can constrain courts below.
Select a court tier to see the difference between the work a court performs, the authority its decisions can carry, and the direction an appeal may travel.
This widget isolates the basic U.S. federal court hierarchy. State courts, specialized federal courts, administrative review, original jurisdiction, interlocutory appeals, en banc review, unpublished opinions, and many jurisdictional details are outside this simplified model.
U.S. Court of Appeals
Reviews federal trial-court decisions and certain agency matters for legal error under the relevant standard of review. Appellate judges ordinarily work from the record rather than retrying the facts from scratch.
Published precedential decisions generally bind federal district courts within that circuit. A circuit does not ordinarily bind the other federal circuits, which is one reason federal law can develop circuit splits.
Parties commonly appeal final federal district-court judgments to the court of appeals with jurisdiction over that district, subject to procedural rules and exceptions.
Before treating a judicial opinion as controlling, ask which court issued it, which jurisdiction you are in, what legal question the holding actually resolved, whether later authority changed the rule, and whether the cited language is part of the holding or merely persuasive discussion.
A legal conclusion is only as strong as its authority, factual fit, procedure, and reasoning path.
The same sentence can mean different things when it appears in a constitution, statute, regulation, majority holding, dissent, contract, or procedural rule. Legal method begins by identifying what kind of source is speaking and what authority it carries.
