How do the other branches check the judicial branch?
Similarly one may ask, how does the judicial branch check the other two branches?
The judicial branch checks the other branches of government by the fact that it is able to say that things they have done are unconstitutional. When it does this, it prevents them from doing things that they are not allowed to do by the Constitution. The Constitution sets various limits on what the government can do.
Considering this, how do the 3 branches of government check each other?
With checks and balances, each of the three branches of government can limit the powers of the others. This way, no one branch becomes too powerful. Each branch “checks” the power of the other branches to make sure that the power is balanced between them.
The President in the executive branch can veto a law, but the legislative branch can override that veto with enough votes. The judicial branch interprets laws, but the President nominates Supreme Court justices, court of appeals judges, and district court judges who make the evaluations.
