Reading: The Legislative Process

Learning Objectives

After reading this section, you should be able to answer the following questions:

  1. How does a bill become law?
  2. How do members of Congress develop and draft legislation?

The primary responsibility of Congress is making laws. Lawmaking is no easy task. Political scientists have characterized Congress as “a procedural obstacle course that favors opponents of legislation and hinders proponents.”[1] It often takes years before a bill is passed. Only a small number of bills that are introduced, formally proposed by members of the House and Senate, become law. On average, close to eleven thousand bills are introduced in the House and Senate during a two-year legislative session and fewer than four hundred become laws.[2]

The process of making laws involves complex written rules and procedures, some of which date back to 1797, when Vice President Thomas Jefferson prepared a rule book to help him carry out his responsibilities as president of the Senate. Jefferson’s Manual was adopted by the House and remains the authoritative statement of rules except where it has been superseded by provisions passed by members. In addition, there are fifteen volumes of parliamentary procedures and supplementary manuals of notes specifying current rules that pertain to lawmaking in the House. Similar reams of codes exist in the Senate.[3]

Making Laws

The textbook legislative process begins when a member of the House or Senate introduces a bill, which then is referred to appropriate committees within each body. Committees decide whether or not a bill is recommended for floor action, where it will be debated and voted on. The House and Senate must pass identical versions of a bill before it can be sent to the president to be signed into law.

Figure 1. How a Bill Becomes a Law

How bill becomes law: In the Senate, a bill is drafted, then introduced and assigned to a member. Then it’s referred to a committee and subcommittee. Next there’s a committee hearing. After that the bill undergoes a subcommittee and full committee markup. The bill is then calendared. There’s a floor reading, debate, and amendments. At that point the bill can be filibustered or put to a full vote in the Senate. If it passes, there’s a conference committee vote by the Houses. The enrolled bill goes to the president, who can either veto or sign the bill. A signed bill becomes law, but a vetoed bill can also become law if a two thirds of Congress vote to override it. The same process takes place in the House of Representatives.

Few bills are passed via the organized, step-by-step, textbook process. Since the 1970s, “unorthodox lawmaking” has become the norm. Most bills wend their way through a circuitous path filled with political and procedural roadblocks.[4]Individual members, especially those seeking reelection, weigh in on bills, resulting in an often contentious atmosphere for lawmaking.

Drafting Legislation

If it is to have much chance of becoming law, a bill must be drafted into a proposal that will generate support in Congress as well as among the public, interest groups, and the executive branch. Bills are drafted by members with the assistance of their staffs and experts in the House and Senate legislative counsel offices.

A bill’s language can be instrumental in generating media publicity and subsequently support for or opposition to it. The title can position the bill in the public debate, as it captures the ideas and images proponents wish to convey. Megan’s Law, which requires communities to publicize the whereabouts of convicted sex offenders, is named after Megan Kanka, a New Jersey girl who was murdered by a sex offender after his release from prison. Politically charged shorthand often is used to characterize bills. The health-care reform legislation passed by Congress and signed into law by President Barack Obama in 2010 has been labeled “Obamacare” by opponents seeking to repeal the legislation.

Introducing Legislation

Members from either the House or Senate can introduce legislation. The member who introduces a bill is its sponsor. Other members can sign on as cosponsors, or supporters, of the bill. Having a large number of cosponsors or having congressional leaders sign onto a bill can boost its chances of success.

Bills are the most typical form of legislation. They can originate in either the House or Senate, with the exception of bills for raising revenue, which must be initiated in the House.[5] The same bill must pass through all the formal procedural hurdles in the House and Senate before it can be sent to the president to be signed into law.

Committee Consideration

After a bill is introduced, it is referred to the standing committee having jurisdiction over its subject matter, such as energy or homeland security, by the presiding officers in each chamber. Having a bill referred to a friendly committee is a key to its potential for success. In the House, but not the Senate, a bill may be considered by more than one committee.[6] Committees in both chambers frequently pass a bill on to a subcommittee that deals with a specialized area of policy contained in the legislation. As more people work on a bill, the less likely it is they will reach consensus and that the bill will move beyond the committee stage.[7]

Committees sometimes request input about a bill from government departments and agencies and hold public hearings where expert witnesses testify. When members seek media coverage of committee hearings, they sometimes will bring in celebrities as witnesses. In 2010, comedian Stephen Colbert testified in front of the House Judiciary Committee in order to bring attention to immigration reform and treatment of farm workers. The performance received mixed reviews from both members of Congress and political commentators.

The full committee votes to determine if the bill will be reported, meaning it will be sent to the floor for debate. If the vote is successful, the committee holds a mark-up session to revise the bill. The committee prepares a report documenting why it supports the bill. The report is sent to the whole chamber, and the bill is placed on the calendar to await floor debate.

In the House, bills must go the Rules Committee before reaching the floor. The Rules Committee assigns a bill a rule that sets the procedures under which the bill will be considered on the floor. The rule establishes the parameters of debate and specifies if amendments, proposed changes to the bill, will be permitted or not. A bill can become stalled if the Rules Committee does not assign it a rule at all or in a timely manner. Rules must be approved by a majority of the members of the House before floor action can begin. There is no Rules Committee in the Senate, where the process of bringing a bill to the floor is simpler and less formal. The Senate majority leader makes a motion to proceed with floor debate.

Floor Action

Once a bill reaches the House or Senate floor, it is debated, amended, and voted on. Many of the bills that make it to the floor are minor bills—noncontroversial measures that have symbolic value, such as naming a post office.[8] Floor consideration of most minor bills is brief, and they are approved by voice vote. Major bills focusing on divisive issues, such as budgetary proposals, health care, and national security, will prompt lengthy debate and amendment proposals before coming to a vote. A bill dies if either chamber fails to pass it.

In the House, bills are considered by the full House meeting in the chamber, which is referred to as the Committee of the Whole. The Speaker of the House chooses a chairperson to oversee floor action. Speakers for and against the bill have an equal amount of time. A general debate of the bill is followed by debate of amendments. A quorum of 218 members is required for a vote on the bill. Yeas and nays are recorded using a computerized system.

Senate floor action is less structured and more unpredictable than the House procedure. Senators are free to speak as long as they like. The filibuster can be used by skillful senators to defeat a bill by “talking it to death.” To avoid lengthy and unproductive floor sessions, the Senate can employ unanimous consent agreements, negotiated agreements that set time limitations on debate.[9] Debate also can be restricted if three-fifths of the senators vote to invoke cloture, a motion to limit consideration of a bill. Getting sixty senators to agree to close debate is not easy, especially on controversial issues. Senators vote on the bill using a traditional call of the roll, with each voice vote recorded manually.

Conference Committee

If House and Senate versions of a bill are not the same, a conference committee is formed to work out the differences. Conference committees consist of members of both houses. In 1934, Senator George Norris (R-NE) characterized conference committees as the “third house of Congress” because of the power they wield in the legislative process.[10] They are the last places in which big changes in legislation can be made. Major changes in the provisions and language of bills are negotiated in conference committees. Up to 80 percent of important bills during a session of Congress end up in conference committees.[11]

During conference committee negotiations, conferees meet informally with party leaders and members who have an interest in the bill. Representatives of the executive branch work with conferees to devise a final bill that the president will be likely to sign. Once an agreement has been reached, the conference committee issues a report that must be passed by the House and Senate before the bill moves forward to be signed into law by the president.[12]

Presidential Approval

Rodgers and Bernice Falk Haydu, and active duty USAF pilots Colonel Dawn Dunlop, Colonel Bobbi Doorenbos, Lieutenant Colonel Wendy Wasik, Major Kara Sandifur and Major Nicole Malachowski (former Thunderbird pilot).

After passing through both houses of Congress, a bill does not become a law until it is signed by the president.

A bill becomes law when it is signed by the president. A president can veto, or reject, a bill by sending it back to Congress with a memorandum indicating his objections.  If the president takes no action and Congress is out of session the bill dies after 10 days: this is known as a pocket veto. Congress can override a veto with a two-thirds vote in each chamber, enabling the bill to become a law over the president’s objections.[13]

Key Takeaways

Making laws is a complex process guided by volumes of rules and influenced by politics. While many bills are proposed each congressional session, few make it all the way through the process to be signed by the president and made law. Congress is responsible for passing legislation enacting the nation’s annual budget, which is frequently a difficult task. The activities of Congress are reported by C-SPAN, which began as a cable network providing gavel-to-gavel coverage of floor proceedings and has expanded to become an extensive resource for information about government and politics.
