The branch that interprets laws is the judicial branch. The judicial branch is responsible for interpreting the meaning of laws, determining the constitutionality of laws, and applying laws to individual cases. The judicial branch is one of the three branches of the U.S. government, along with the legislative and executive branches. The Constitution of the United States divides the federal government into these three branches to ensure that no individual or group will have too much power. The judicial branch is responsible for maintaining the system of checks and balances, which allows each branch of government to respond to the actions of the other branches.
