Section 1. A Two-House Legislature

   
The Capitol Building
The Capitol Building
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.
 
  The Constitution gives Congress the power to make laws. Congress is divided into the Senate and the House of Representatives.
     

Section 2. House of Representatives

   
1. Election of Members
The House of Representatives shall be composed of members chosen every second year by the people of the several states, and the electors in each state shall have the qualifications requisite for electors of the most numerous branch of the state legislature.
  Clause 1 Electors refers to voters. Members of the House of Representatives are elected every two years. Any citizen allowed to vote for members of the larger house of the state legislature can also vote for members of the House.

 

   
2. Qualifications
No person shall be a Representative who shall not have attained to the age of twenty-five years, and been seven years a citizen of the United States, and who shall not, when elected, be an inhabitant of that state in which he shall be chosen.
  Clause 2 A member of the House of Representatives must be at least 25 years old, an American citizen for 7 years, and a resident of the state he or she represents.

and direct taxes shall be apportioned among the several states which may be included within this Union, according to their respective numbers which shall be determined by adding to the whole number of free persons, including those bound to service for a term of years, and excluding Indians not taxed, three-fifths of all other persons. The actual enumeration shall be made within three years after the first meeting of the Congress of the United States, and within every subsequent term of ten years, in such manner as they shall by law direct. The number of Representatives shall not exceed one for every 30,000, but each state shall have at least one Representative; and until such enumeration shall be made, the state of New Hampshire shall be entitled to choose three; Massachusetts, eight; Rhode Island and Providence Plantations, one; Connecticut, five; New York, six; New Jersey, four; Pennsylvania, eight; Delaware, one; Maryland, six; Virginia, ten; North Carolina, five; South Carolina, five; and Georgia, three.
  Clause 3 The number of representatives each state elects is based on its population. An enumeration, or census, must be taken every 10 years to determine population. Today, the number of representatives in the House is fixed at 435.

This is the famous Three-Fifths Compromise worked out at the Constitutional Convention. Persons bound to service meant indentured servants. All other persons meant slaves. All free people in a state were counted. However, only three fifths of the slaves were included in the population count. This three-fifths clause became meaningless when slaves were freed by the Thirteenth Amendment.

 

   
4. Filling Vacancies
When vacancies happen in the representation from any state, the executive authority thereof shall issue writs of election to fill such vacancies.
  Clause 4 Executive authority means the governor of a state. If a member of the House leaves office before his or her term ends, the governor must call a special election to fill the seat.
     
5. Selection of Officers; Power of Impeachment
The Impeachment Process
The Impeachment Process

The House of Representatives shall choose their Speaker and other officers; and shall have the sole power of impeachment.
  Clause 5 The House elects a speaker. Today, the speaker is usually chosen by the party that has a majority in the House. Also, only the House has the power to impeach, or accuse, a federal official of wrongdoing.
     
Section 3. The Senate

   
1. Selection of Members
The Senate of the United States shall be composed of two Senators from each state chosen by the legislature thereof, for six years, and each Senator shall have one vote.
  Clause 1 Each state has two senators. Senators serve for six-year terms. The Seventeenth Amendment changed the way senators were elected.
     
2. Alternating Terms; Filling Vacancies
Immediately after they shall be assembled in consequence of the first election, they shall be divided as equally as may be into three classes. The seats of the Senators of the first class shall be vacated at the expiration of the second year, of the second class at the expiration of the fourth year, and of the third class at the expiration of the sixth year, so that one-third may be chosen every second year; and if vacancies happen by resignation, or otherwise, during the recess of the legislature of any state, the executive thereof may make temporary appointments until the next meeting of the legislature, which shall then fill such vacancies.
  Clause 2 Every two years, one third of the senators run for reelection. Thus, the makeup of the Senate is never totally changed by any one election. The Seventeenth Amendment changed the way that vacancies, or empty seats, are filled. Today, the governor of a state must choose a senator to fill a vacancy that occurs between elections.
     
3. Qualifications
No person shall be a Senator who shall not have attained to the age of thirty years, and been nine years a citizen of the United States, and who shall not, when elected, be an inhabitant of that state for which he shall be chosen.
  Clause 3 A senator must be at least 30 years old, an American citizen for 9 years, and a resident of the state he or she represents.
     
4. President of the Senate
The Vice-President of the United States shall be president of the Senate, but shall have no vote, unless they be equally divided.
  Clause 4 The Vice President presides over Senate meetings, but he or she can vote only to break a tie.
     
5. Election of Senate Officers
The Senate shall choose their other officers, and also a president pro tempore, in the absence of the Vice-President, or when he shall exercise the office of the President of the United States.
  Clause 5 Pro tempore means "temporary." The Senate chooses one of its members to serve as president pro tempore when the Vice President is absent.
     
6. Impeachment Trials
Senate Impeachment Trial of Andrew Johnson
Senate Impeachment Trial of Andrew Johnson

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.
  Clause 6 The Senate acts as a jury if the House impeaches a federal official. The Chief Justice of the Supreme Court presides if the President is on trial. Two thirds of all senators present must vote for conviction, or finding the accused guilty. No President has ever been convicted. The House impeached President Andrew Johnson in 1868, but the Senate acquitted him of the charges. President Bill Clinton was impeached by the House in December 1998. His Senate trial also ended in aquittal. In 1974, President Richard Nixon resigned before he could be impeached.
     
7. Penalties Upon Conviction
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.
  Clause 7 If an official is found guilty by the Senate, he or she can be removed from office and barred from holding federal office in the future. These are the only punishments the Senate can impose. However, the convicted official can still be tried in a criminal court.
     
Section 4. Elections and Meetings

   
1. Election of Congress
Major Differences Between the House and Senate
Major Differences Between the House and Senate

The times, places, and manner of holding elections for Senators and Representatives shall be prescribed in each state by the legislature thereof; but the Congress may at any time by law make or alter such regulations, except as to the places of choosing Senators.
  Clause 1 Each state legislature can decide when and how congressional elections take place, but Congress can overrule these decisions. In 1842, Congress required each state to set up congressional districts with one representative elected from each district. In 1872, Congress decided that congressional elections must be held in every state on the same date in even-numbered years.

Supreme Court Cases

     
2. Annual Sessions
The Congress shall assemble at least once in every year, and such meeting shall be on the first Monday in December, unless they shall by law appoint a different day.
  Clause 2 Congress must meet at least once a year. The Twentieth Amendment moved the opening date of Congress to January 3.
     
Section 5. Rules for the Conduct of Business

   
1. Organization
Each house shall be the judge of the elections, returns, and qualifications of its own members, and a majority of each shall constitute a quorum to do business; but a smaller number may adjourn from day to day, and may be authorized to compel the attendance of absent members, in such manner, and under such penalties, as each house may provide.
  Clause 1 Each house decides whether a member has the qualifications for office set by the Constitution. A quorum is the smallest number of members who must be present for business to be conducted. Each house can set its own rules about absent members.
     
2. Procedures
Each house may determine the rules of its proceedings, punish its members for disorderly behavior, and with the concurrence of two-thirds, expel a member.
  Clause 2 Each house can make rules for the conduct of members. It can only expel a member by a two-thirds vote.
     
3. A Written Record
Each house shall keep a journal of its proceedings, and from time to time publish the same, excepting such parts as may in their judgment require secrecy; and the yeas and nays of the members of either house on any question shall, at the desire of one-fifth of those present, be entered on the journal.
  Clause 3 Each house keeps a record of its meetings. The Congressional Record is published every day with excerpts from speeches made in each house. It also records the votes of each member.
     
4. Rules for Adjournment
Neither house, during the session of Congress, shall, without the consent of the other, adjourn for more than three days, nor to any other place than that in which the two houses shall be sitting.
  Clause 4 Neither house can adjourn, or stop meeting, for more than three days unless the other house approves. Both houses of Congress must meet in the same city.
     
Section 6. Privileges and Restrictions

   
1. Salaries and Immunities
The Senators and Representatives shall receive a compensation for their services, to be ascertained by law and paid out of the Treasury of the United States. They shall in all cases, except treason, felony, and breach of the peace, be privileged from arrest during their attendance at the session of their respective houses, and in going to and returning from the same; and for any speech or debate in either house, they shall not be questioned in any other place.
 

Clause 1 Compensation means "salary." Congress decides the salary for its members. While Congress is in session, a member is free from arrest in civil cases and cannot be sued for anything he or she says on the floor of Congress. This allows for freedom of debate. However, a member can be arrested for a criminal offense.

Supreme Court Cases

     
2. Restrictions on Other Employment
No Senator or Representative shall, during the time for which he was elected, be appointed to any civil office under the authority of the United States, which shall have been created, or the emoluments whereof shall have been increased, during such time; and no person holding any office under the United States shall be a member of either house during his continuance in office.
  Clause 2 Emolument also means "salary." A member of Congress cannot hold another federal office during his or her term. A former member of Congress cannot hold an office created while he or she was in Congress. An official in another branch of government cannot serve at the same time in Congress. This strengthens the separation of powers.
     
Section 7. Law-Making Process

   
1. Tax Bills
All bills for raising revenue shall originate in the House of Representatives; but the Senate may propose or concur with amendments as on other bills.
  Clause 1 Revenue is money raised by the government through taxes. Tax bills must be introduced in the House. The Senate, however, can make changes in tax bills. This clause protects the principle that people can be taxed only with their consent.

The Number of Bills That Become Laws
The Number of Bills That Become Laws
Every bill which shall have passed the House of Representatives and the Senate shall, before it become a law, be presented to the President of the United States; if he approve, he shall sign it, but if not, he shall return it, with his objections, to that house in which it shall have originated, who shall enter the objections at large on their journal, and proceed to reconsider it. If after such reconsideration two-thirds of that house shall agree to pass the bill, it shall be sent, together with the objections, to the other house, by which it shall likewise be reconsidered, and, if approved by two-thirds of that house, it shall become a law. But in all such cases the votes of both houses shall be determined by yeas and nays, and the names of the persons voting for and against the bill shall be entered on the journal of each house respectively. If any bill shall not be returned by the President within ten days (Sundays excepted) after it shall have been presented to him, the same bill shall be a law, in like manner as if he had signed it, unless the Congress by their adjournment prevent its return, in which case it shall not be a law.
 
  Clause 2 A bill, or proposed law, that is passed by a majority of the House and Senate is sent to the President. If the President signs the bill, it becomes law.

A bill can also become law without the President's signature. The President can refuse to act on a bill. If Congress is in session at the time, the bill becomes law 10 days after the President receives it.

The President can veto, or reject, a bill by sending it back to the house where it was introduced. Or if the President refuses to act on a bill and Congress adjourns within 10 days, then the bill dies. This way of killing a bill without taking action is called the pocket veto.

Congress can override the President's veto if each house of Congress passes the bill again by a two-thirds vote. This clause is an important part of the system of checks and balances.
     
3. Resolutions Passed by Congress
Types of Bills and Resolutions
Types of Bills and Resolutions
Every order, resolution, or vote to which the concurrence of the Senate and House of Representatives may be necessary (except on a question of adjournment) shall be presented to the President of the United States; and before the same shall take effect, shall be approved by him, or being disapproved by him, shall be repassed by two-thirds of the Senate and House of Representatives, according to the rules and limitations prescribed in the case of a bill.
  Clause 3 Congress can pass resolutions or orders that have the same force as laws. Any such resolution or order must be signed by the President (except on questions of adjournment). This clause prevents Congress from bypassing the President simply by calling a bill by another name.
     
Section 8. Powers Delegated to Congress

   
The Congress shall have power

   
1. Taxes
To lay and collect taxes, duties, imposts, and excises, to pay the debts and provide for the common defense and general welfare of the United States; but all duties, imposts, and excises shall be uniform throughout the United States;
  Clause 1 Duties are tariffs. Imposts are taxes in general. Excises are taxes on the production or sale of certain goods. Congress has the power to tax and spend tax money. Taxes must be the same in all parts of the country.
     
2. Borrowing
To borrow money on the credit of the United States;
  Clause 2 Congress can borrow money for the United States. The government often borrows money by selling bonds, or certificates that promise to pay the holder a certain sum of money on a certain date.
     
3. Commerce
To regulate commerce with foreign nations, and among the several states, and with the Indian tribes;
 

Clause 3 Only Congress has the power to regulate foreign and interstate trade, or trade between states. Disagreement over interstate trade was a major problem with the Articles of Confederation.

Supreme Court Cases

     
4. Naturalization; Bankruptcy
To establish a uniform rule of naturalization, and uniform laws on the subject of bankruptcies throughout the United States;
  Clause 4 Naturalization is the process whereby a foreigner becomes a citizen. Bankruptcy is the condition in which a person or business cannot pay its debts. Congress has the power to pass laws on these two issues. The laws must be the same in all parts of the country.
     
5. Coins; Weights; Measures
To coin money, regulate the value thereof, and of foreign coin, and fix the standard of weights and measures;
  Clause 5 Congress has the power to coin money and set its value. Congress has set up the National Bureau of Standards to regulate weights and measures.
     
6. Counterfeiting
To provide for the punishment of counterfeiting the securities and current coin of the United States;
  Clause 6 Counterfeiting is the making of imitation money. Securities are bonds. Congress can make laws to punish counterfeiters.
     
7. Post Offices
To establish post offices and post roads;
  Clause 7 Congress has the power to set up and control the delivery of mail.
     
8. Copyrights; Patents
To promote the progress of science and useful arts by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries;
  Clause 8 Congress may pass copyright and patent laws. A copyright protects an author. A patent makes an inventor the sole owner of his or her work for a limited time.
     
9. Federal Courts
To constitute tribunals inferior to the Supreme Court;
  Clause 9 Congress has the power to set up inferior, or lower, federal courts under the Supreme Court.
     
10. Piracy
To define and punish piracies and felonies committed on the high seas and offenses against the law of nations;
  Clause 10 Congress can punish piracy, or the robbing of ships at sea.
     
11. Declarations of War
To declare war, grant letters of marque and reprisal, and make rules concerning captures on land and water;
  Clause 11 Only Congress can declare war. Declarations of war are granted at the request of the President. Letters of marque and reprisal were documents issued by a government allowing merchant ships to arm themselves and attack ships of an enemy nation. They are no longer issued.
     
12. Army
The Implied Powers of Congress
The Implied Powers of Congress

To raise and support armies, but no appropriation of money to that use shall be for a longer term than two years;

13. Navy
To provide and maintain a navy;

14. Rules for the Military
To make rules for the government and regulation of the land and naval forces;
 
 

Clauses 12, 13, 14 These clauses place the army and navy under the control of Congress. Congress decides on the size of the armed forces and the amount of money to spend on the army and navy. It also has the power to write rules governing the armed forces.

Supreme Court Cases

     
15. Militia
To provide for calling forth the militia to execute the laws of the Union, suppress insurrections, and repel invasions;

16. Rules for the Militia
To provide for organizing, arming, and disciplining the militia, and for governing such part of them as may be employed in the service of the United States, reserving to the states, respectively, the appointment of the officers, and the authority of training the militia according to the discipline prescribed by Congress;
  Clauses 15, 16 The militia is a body of citizen soldiers. Congress can call up the militia to put down rebellions or fight foreign invaders. Each state has its own militia, today called the National Guard. Normally, the militia is under the command of a state's governor. However, it can be placed under the command of the President.
     
17. National Capital
To exercise exclusive legislation in all cases whatsoever, over such district (not exceeding ten miles square) as may, by cession of particular states, and the acceptance of Congress, become the seat of government of the United States, and to exercise like authority over all places purchased by the consent of the legislature of the state in which the same shall be, for the erection of forts, magazines, arsenals, dock-yards, and other needful buildings;—and
  Clause 17 Congress controls the district around the national capital. In 1790, Congress made Washington, D.C., the nation's capital. In 1973, it gave residents of the District the right to elect local officials.
     
18. Necessary Laws
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.
 

Clause 18 Clauses 1–17 list the powers delegated to Congress. The writers of the Constitution added Clause 18 so that Congress could deal with the changing needs of the nation. It gives Congress the power to make laws as needed to carry out the first 17 clauses. Clause 18 is sometimes called the elastic clause because it lets Congress stretch the meaning of its power.

Supreme Court Cases

     
Section 9. Powers Denied to the Federal                 Government

   
1. The Slave Trade
The migration or importation of such persons as any of the states now existing shall think proper to admit shall not be prohibited by the Congress prior to the year 1808; but a tax or duty may be imposed on such importation, not exceeding $10 for each person.
  Clause 1 Such persons refers to slaves. This clause resulted from a compromise between the supporters and the opponents of the slave trade. In 1808, as soon as Congress was permitted to abolish the slave trade, it did so. The $10 import tax was never imposed.
     
2. Writ of Habeas Corpus
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.
 

Clause 2 A writ of habeas corpus is a court order requiring government officials to bring a prisoner to court and explain why he or she is being held. A writ of habeas corpus protects people from unlawful imprisonment. The government cannot suspend this right except in times of rebellion or invasion.

Supreme Court Cases

     
3. Bills of Attainder and Ex Post Facto Laws
No bill of attainder or ex post facto law shall be passed.
  Clause 3 A bill of attainder is a law declaring that a person is guilty of a particular crime. An ex post facto law punishes an act which was not illegal when it was committed. Congress cannot pass a bill of attainder or ex post facto laws.
     
4. Apportionment of Direct Taxes
No capitation or other direct tax shall be laid, unless in proportion to the census or enumeration herein before directed to be taken.
  Clause 4 A capitation tax is a tax placed directly on each person. Direct taxes are taxes on people or on land. They can be passed only if they are divided among the states according to population. The Sixteenth Amendment allowed Congress to tax income without regard to the population of the states.
     
5. Taxes on Exports
No tax or duty shall be laid on articles exported from any state.
  Clause 5 This clause forbids Congress to tax exports. In 1787, southerners insisted on this clause because their economy depended on exports.
     
6. Special Preference for Trade
No preference shall be given any regulation of commerce or revenue to the ports of one state over those of another; nor shall vessels bound to, or from, one state, be obliged to enter, clear, or pay duties in another.
  Clause 6 Congress cannot make laws that favor one state over another in trade and commerce. Also, states cannot place tariffs on interstate trade.
     
7. Spending
No money shall be drawn from the Treasury, but in consequence of appropriations made by law; and a regular statement and account of the receipts and expenditures of all public money shall be published from time to time.
  Clause 7 The federal government cannot spend money unless Congress appropriates it, or passes a law allowing it. This clause gives Congress an important check on the President by controlling the money he or she can spend. The government must publish a statement showing how it spends public funds.
     
8. Creation of Titles of Nobility
No title of nobility shall be granted by the United States; and no person holding any office of profit or trust under them, shall, without the consent of the Congress, accept of any present, emolument, office, or title, of any kind whatever, from any king, prince, or foreign state.
  Clause 8 The government cannot award titles of nobility, such as Duke or Duchess. American citizens cannot accept titles of nobility from foreign governments without the consent of Congress.
     
Section 10. Powers Denied to the States

   
1. Unconditional Prohibitions
No state shall enter into any treaty, alliance, or confederation; grant letters of marque and reprisal; coin money; emit bills of credit; make anything but gold and silver coin a tender in payment of debts; pass any bill of attainder, ex post facto law, or law impairing the obligation of contracts, or grant any title of nobility.
  Clause 1 The writers of the Constitution did not want the states to act like separate nations. So they prohibited states from making treaties or coining money. Some powers denied to the federal government are also denied to the states. For example, states cannot pass ex post facto laws.
     
2. Powers Conditionally Denied
No state shall, without the consent of the Congress, lay any imposts or duties on imports or exports, except what may be absolutely necessary for executing its inspection laws; and the net produce of all duties and imposts, laid by any state on imports or exports, shall be for the use of the Treasury of the United States; and all such laws shall be subject to the revision and control of the Congress.

3. Other Denied Powers
No state shall, without the consent of Congress, lay any duty of tonnage, keep troops, or ships of war in time of peace, enter into any agreement or compact with another state, or with a foreign power, or engage in war, unless actually invaded, or in such imminent danger as will not admit of delay.
  Clauses 2, 3 Powers listed here are forbidden to the states, but Congress can lift these prohibitions by passing laws that give these powers to the states.

Clause 2 forbids states from taxing imports and exports without the consent of Congress. States may charge inspection fees on goods entering the states. Any profit from these fees must be turned over to the United States Treasury.

Clause 3 forbids states from keeping an army or navy without the consent of Congress. States cannot make treaties or declare war unless an enemy invades or is about to invade.
