Some examples of expressed powers of Congress include the ability to declare war, the authority to collect taxes, initiate and approve legislation and establish federal courts. Some examples of the express powers of the president include the ability to act as Commander in Chief of United States military forces, appoint treaties, appoint cabinet officials and Supreme Court justices and make treaties with foreign officials.
Express powers are those powers that are explicitly granted under each of the Articles of the U.S. Constitution. The branches of the government also have implied powers. Implied powers are those powers that are not explicitly stated but are implied because they are necessary for the respective branches of the government to be able to carry out their duties. According to the Constitution, those powers not expressed or implied to the federal government default to the individual states. In most cases, the states and government work together in matters that default to the states. Taxation, for instance is a shared power. The federal government determines a federal tax. States and municipalities, however, also have the ability to tax citizens. The judicial branch is also a shared power. The Supreme Court is the only court actually prescribed by the Constitution. The lower courts that are maintained throughout the states, though not established by the judicial branch of government, uphold the interpretations of the law that are issued down from the Supreme Court.
