Decisions made by the U.S. Court of Appeals are based on Constitutional law?

Decisions made by the U.S. Court of Appeals often involve the interpretation of Constitutional law, as these courts review cases that challenge or uphold laws based on constitutional principles. They assess whether lower courts applied the law correctly and whether any constitutional rights were violated. However, their rulings can also involve statutory interpretation, administrative regulations, and other legal principles, not solely limited to constitutional issues. Ultimately, their decisions can significantly influence the interpretation and application of constitutional law across the United States.
