Which body is responsible for interpreting laws in the United States?

The judicial branch is responsible for interpreting laws in the United States. This branch encompasses the court system, which includes the Supreme Court, appellate courts, and lower courts. The judiciary has the authority to review laws, determine their constitutionality, and apply them to individual cases. Through this process, the judicial branch ensures that laws are interpreted and enforced fairly and that they align with the Constitution.

Judicial review is a significant function of the courts, allowing them to assess whether legislation or executive actions comply with constitutional principles. This mechanism is vital for maintaining the rule of law and protecting individual rights. By interpreting laws and resolving disputes related to them, the judicial branch upholds the principles of justice and accountability within the government.
