The judicial branch checks the legislative branch by reviewing laws for constitutionality. Any law is subject to challenge on the grounds that it violates rights ensured under the US Constitution. The judicial branch also checks all executive orders or actions for constitutionality. In either case, it has the ability to overturn unconstitutional laws and executive orders or actions. Further, the court can limit the scope of a law by narrowly or broadly interpreting it in a manner that does not infringe upon constitutional rights.
