(18) “To make all laws which shall be necessary and proper for carrying into execution the foregoing powers and all other powers vested by this Constitution in the government of the United States, or in any department or officer thereof.”

(19) “Congress may determine the time of choosing the electors” for President and Vice President of the United States, “and the day on which they shall give their votes, which day shall be the same throughout the United States.”

(20) “Congress may, by law, provide for the case of removal, death, resignation, or inability of both the President and Vice President, declaring what officer shall then act as President.”

(21) “The Congress may, by law, vest the appointment of such inferior officers as they think proper, in the President alone, in the courts of law, or in the heads of departments.”

(22) “The Congress shall have power to declare the punishment of treason.”

(23) “Full faith and credit shall be given in each State, to the public acts, records, and judicial proceedings of every other State.  And the Congress may, by general laws, prescribe the manner in which such acts, records, and proceedings shall be proved, and the effect thereof.”

(24) “New States may be admitted by the Congress into this Union, but no new State shall be formed or erected within the jurisdiction of any other State, nor any State be formed by the junction of two or more States, or parts of States, without the consent of the legislatures of the States concerned, as well as of the Congress.”

(25) “The Congress shall have power to dispose of, and to make all needful rules and regulations respecting the territory or other property belonging to the United States; and nothing in this Constitution shall be so construed as to prejudice any claims of the United States or of any particular State.”

(26) Congress has “power to enforce, by appropriate legislation,” all provisions of the Constitution.

Under the authority “to provide for the general welfare of the United States,” Congress exercises powers which are implied—­that is, understood—­but which are not expressly named in the Constitution.  The grants of public lands to railway and canal companies, the annual appropriations for the improvement of rivers and harbors, and numerous similar laws are based upon implied powers.

FORBIDDEN POWERS.—­The following powers are expressly denied to the national government: 

(1) “The privilege of the writ of habeas corpus shall not be suspended unless when, in cases of rebellion or invasion, the public safety may require it.”

Habeas corpus means “Thou mayst have the body.”  A person in prison, claiming to be unlawfully detained, or the friend of such a person, applies to the judge of a court for a writ of habeas corpus.  The judge issues the writ, which directs the officer to bring the body of the prisoner into court at a certain time and place, in order that the legality of the imprisonment may be tested.
