Who is responsible for interpreting laws?

The judicial branch is responsible for interpreting laws in the United States. This function is essential for maintaining the rule of law and ensuring that laws are applied fairly and consistently. Courts, which are integral to the judicial branch, have the authority to evaluate laws' constitutionality, resolve disputes regarding their application, and clarify how they should be understood in various contexts.

Through judicial review, a process established in Marbury v. Madison, the courts can strike down laws or executive actions that they determine to be unconstitutional. This power serves as a check on the legislative and executive branches, helping to uphold the principles of justice and protect individual rights. The ability of judges to interpret laws also extends to administrative regulations and local ordinances, ensuring that all levels of government adhere to constitutional principles.
