Which body primarily interprets the laws in the United States?

The judiciary is the body primarily responsible for interpreting the laws in the United States. This includes the court system at both the federal and state levels, where judges and justices analyze laws, resolve disputes, and determine the constitutionality of legislative acts and executive actions. The role of the judiciary is critical in ensuring that laws are applied fairly and consistently, protecting the rights of individuals and maintaining the rule of law.

This function is distinct from that of the legislative branch, which is mainly tasked with creating laws, and the executive branch, which implements and enforces those laws. Bureaucratic agencies, while they help in administering laws and regulations, do not have the authority to interpret laws in the way that courts do. Hence, the judiciary's unique role in interpreting laws is a foundational aspect of the U.S. legal system, ensuring that the intentions of the law are upheld and applied in practice.
