In the United States Constitution, the three different branches of the federal government each have unique powers. The legislative branch (Congress) has the ability to make laws, the executive branch (president) has the ability to enforce laws, and the judicial branch (Supreme Court) has the power to interpret laws. This system ensures that no one group of politicians have too much political power.
This concept applies to the appointment of federal judges as well. The executive branch has the ability to nominate judges. However, these judges must be approved by Congress. This check on the power of the president makes it so that Congress can ask questions and make sure that the person being nominated for this job is qualified to perform it.
