Separation of powers under the United States Constitution:

The power to review the constitutionality of laws may be limited by Congress, which has the power to set the jurisdiction of the courts. The only constitutional limit on Congress' power to set the jurisdiction of the judiciary relates to the Supreme Court; the Supreme Court may exercise only appellate jurisdiction except in cases involving states and cases affecting foreign ambassadors, ministers or consuls.
