Question

How does the legislative branch check the judicial branch?

Answer 1

The executive branch can veto the law, thus making it harder for the legislative branch to pass the law. The judicial branch may also say that the law is unconstitutional and thus make sure it is not a law. The legislative branch can also remove a president or judge that is not doing his/her job properly.
It's also known as "Checks and Balances"

Checks and balances
