What is the main responsibility of the judicial branch?

The primary responsibility of the judicial branch is to interpret laws and determine whether they are constitutional. This function is vital in maintaining the rule of law and protecting individual rights and freedoms as guaranteed by the Constitution. When legal disputes arise, it is the job of the judicial branch, often through the court system, to resolve these issues by evaluating the legality and constitutionality of laws, regulations, and actions conducted by other branches of government or parties. This ensures that all laws align with the Constitution and adhere to the principles laid out by the founding documents of the nation.

The role of the judicial branch also acts as a check on the powers of the executive and legislative branches, providing a balance within the government. This function is key to upholding democratic governance and protecting citizens from potential overreach by government entities. Thus, the ability to evaluate the constitutionality of laws is central to the judicial branch's purpose and function in the broader framework of government.
