“We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.”

The Preamble states the broad purposes the Constitution is intended to serve – to establish a government that provides for greater cooperation among the states, ensures justice and peace, provides for defense against foreign enemies, promotes the general well-being of the people, and secures liberty now and in the future. The phrase “We the People” emphasizes the twin concepts of popular sovereignty and of representative government.

Article I: Legislative Branch

Section 1.
All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives.

Legislative power; congress
Congress, the nation’s lawmaking body, is bicameral in form; that is, it is composed of two houses: the Senate and the House of Representatives. The Framers of the Constitution purposely separated the lawmaking power from the power to enforce the laws (Article II, the Executive Branch) and the power to interpret them (Article III, the Judicial Branch). This system of separation of powers is supplemented by a system of checks and balances; that is, in several provisions the Constitution gives to each of the three branches various powers with which it may check, restrain, the actions of the other two branches.

Article II: Executive Branch

Section 1.
The executive Power shall be vested in a President of the United States of America. He shall hold his Office during the Term of four Years, and, together with the Vice President, chosen for the same Term, be elected as follows:

Executive power; term
This clause gives to the President the very broad “executive power,” the power to enforce the laws and otherwise administer the public policies of the United States. It also sets the length of the presidential (and vice-presidential) term of office; see the 22nd Amendment (1951), which places a limit on presidential (but not vice-presidential) tenure.

Article III: Judicial Branch

Section 1.
The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish. The Judges, both of the supreme and inferior Courts, shall hold their Offices during good Behavior, and shall, at stated Times, receive for their Services, a Compensation, which shall not be diminished during their Continuance in Office.

Judicial courts; terms of office
The judicial power conferred here is the power of federal courts to hear and decide cases, disputes between the government and individuals and between private persons (parties). The Constitution creates only the Supreme Court of the United States; it gives to Congress the power to establish other, lower federal courts (Article I, Section 8, Clause 9) and to fix the size of the Supreme Court. The words “during good behavior” mean, in effect, for life.

Amendments to the Constiution

The first 10 amendments, the Bill of Rights, were each proposed by Congress on September 25, 1789, and ratified by the necessary three-fourths of the States on December 15, 1791. These amendments were originally intended to restrict the National Government—not the States. However, the Supreme Court has several times held that most of their provisions also apply to the States, through the 14th Amendment’s Due Process Clause.

1st Amendment: Freedom of Religion, Speech, Press, Assembly, and Petition.
“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof, or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.”

The 1st Amendment sets out five basic liberties: The guarantee of freedom of religion is both a protection of religious thought and practice and a command of separation of church and state. The guarantees of freedom of speech and press assure to all persons a right to speak, publish, and otherwise express their views. The guarantees of the rights of assembly and petition protect the right to join with others in public meetings, political parties, pressure groups, and other associations to discuss public affairs and influence public policy. None of these rights is guaranteed in absolute terms, however; like all other civil rights guarantees, each of them may be exercised only with regard to the rights of all other persons.

2nd Amendment: The Right to Bear Arms
“A well-regulated Militia being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.”

Each State has the right to maintain a militia, an armed force for its own protection—today, the National Guard. The National Government and the States can and do regulate the private possession and use of firearms.

3rd Amendment: Quartering of Troops
“No Soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor, in time of war, but in a manner to be prescribed by law.”

This amendment was intended to prevent what had been common British practice in the colonial period; see the Declaration of Independence. This provision is of virtually no importance today.

4th Amendment: Searches and Seizures
“The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.”

The basic rule laid down by the 4th Amendment is this: Police officers have no general right to search for or seize evidence or seize (arrest) persons. Except in particular circumstances, they must have a proper warrant (a court order) obtained with probable cause (on reasonable grounds). This guarantee is reinforced by the exclusionary rule, developed by the Supreme Court: Evidence gained as the result of an unlawful search or seizure cannot be used at the court trial of the person from whom it was seized.

5th Amendment: Criminal Proceedings; Due Process; Eminent Domain
“No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War, or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.”

A person can be tried for a serious federal crime only if he or she has been indicted (charged, accused of that crime) by a grand jury. No one may be subjected to double jeopardy—that is, tried twice for the same crime. All persons are protected against self-incrimination; no person can be legally compelled to answer any question in any governmental proceeding if that answer could lead to that person’s prosecution. The 5th Amendment’s Due Process Clause prohibits unfair, arbitrary actions by the Federal Government; a like prohibition is set out against the States in the 14th Amendment. Government may take private property for a legitimate public purpose; but when it exercises that power of eminent domain, it must pay a fair price for the property seized.

6th Amendment: Rights in Criminal Proceedings
“In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence.”

A person accused of crime has the right to be tried in court without undue delay and by an impartial jury; see Article III, Section 2, Clause 3. The defendant must be informed of the charge upon which he or she is to be tried, has the right to cross-examine hostile witnesses, and has the right to require the testimony of favorable witnesses. The defendant also has the right to be represented by an attorney at every stage in the criminal process.

7th Amendment: Civil Trials
“In Suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved, and no fact tried by a jury, shall be otherwise re-examined in any Court of the United States, than according to the rules of the common law. ”

This amendment applies only to civil cases heard in federal courts. A civil case does not involve criminal matters; it is a dispute between private parties or between the government and a private party. The right to trial by jury is guaranteed in any civil case in a federal court if the amount of money involved in that case exceeds $20 (most cases today involve a much larger sum); that right may be waived (relinquished, put aside) if both parties agree to a bench trial (a trial by a judge, without a jury).

8th Amendment: Punishment for Crimes
“Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishment inflicted. “

Bail is the sum of money that a person accused of crime may be required to post (deposit with the court) as a guarantee that he or she will appear in court at the proper time. The amount of bail required and/or a fine imposed as punishment must bear a reasonable relationship to the seriousness of the crime involved in the case. The prohibition of cruel and unusual punishment forbids any punishment judged to be too harsh, too severe for the crime for which it is imposed.

9th Amendment: Unenumerated Rights
“The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.”

The fact that the Constitution sets out many civil rights guarantees, expressly provides for many protections against government, does not mean that there are not other rights also held by the people.

10th Amendment: Powers Reserved to the States
“The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.”

This amendment identifies the area of power that may be exercised by the States. All of those powers the Constitution does not grant to the National Government, and at the same time does not forbid to the States, belong to each of the States, or to the people of each State.
