(Part 1 of 6)
PROVISIONS ON IMPEACHMENT IN THE U.S. CONSTITUTION
Impeachment is the direct constitutional means for removing a President, Vice President or other civil officers of the United States who have acted or threatened acts that are serious offenses against the Constitution, its system of government, or the rule of law, or that are conventional crimes of such a serious nature that they would injure the Presidency if there was no removal.
The power of impeachment is a vital part of the Constitution. It was among the proposals first presented to the Constitutional Convention in 1787. Its terms were debated repeatedly and remained prominently in the text from the first drafts of the Constitution to the final document. Impeachment is more fully and carefully detailed in substance and procedure than any other power delegated to the Congress by the Constitution. Provisions relating to impeachment appear six times in text of the Constitution and once in an Amendment. They are:
1. Article I, which creates the legislative branch of government, in Section 2, para. 4 provides:
that the House of Representatives... "shall have the sole power of impeachment."
2. Article I, Section 3, para. 6 provides:
"The Senate shall have the sole Power to try all Impeachments. When sitting for that Purpose, they shall be on Oath or Affirmation. When the President of the United States is tried, the Chief Justice shall preside: And no Person shall be convicted without the Concurrence of two thirds of the Members present."
3. Article I, Section 3, paragraph 7 provides:
Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States: but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law."
4. Article II, which creates the Executive branch, in Section 2 provides the President:
...shall have Power to Grant Reprieves and Pardons for Offenses against the United States, except in Cases of Impeachment.
5. Article II, Section 4 provides:
The President, Vice President and all civil Officers of the United States, shall be removed from Office on Impeachment for, and Conviction of , Treason, Bribery, or other high Crimes and Misdemeanors.
6. Article III which creates the Judicial branch of government, in Section 2, paragraph 3 provides:
The trial of all Crimes, except in Cases of Impeachment, shall be by Jury... .
7. Amendment XXV to the Constitution ratified on February 10. 1967 provides in Section 1:
In case of the removal of the President from office or of his death or resignation, the Vice President shall become President.
The power of impeachment was placed in the Constitution to protect the Constitution and the people from a despotic, or lawless President.Much more at: http://www.votetoimpeach.org /
