A bill is a proposed law under consideration by a legislature. A bill does not become law until it is passed by the legislature and, in most cases, approved by the executive. Once a bill has been enacted into law, it is called an act or a statute.
A bill is introduced by a member of the legislature (in the house of commons). This takes a variety of forms. In the British/Westminster system, where the executive is drawn from the legislature and usually holds a majority in the lower house, most bills are introduced by the executive. In principle, the legislature meets to consider the demands of the executive, as set out in the Queen's Speech or Speech from the Throne.
While mechanisms exist to allow other members of the legislature to introduce bills, these are subject to strict timetables and usually fail unless a consensus is reached. In the US system, where the executive is formally separated from the legislature, all bills must originate from the legislature. Bills can be introduced using the following procedures:
- Leave: A motion is brought before the chamber asking that leave be given to bring in a bill. This is used in the British system in the form of the Ten Minute Rule motion. The legislator has 10 minutes to propose a bill, which can then be considered by the House on a day appointed for the purpose. While this rule remains in place in the rules of procedure of the US Congress, it is seldom used.
- Government motion: In jurisdictions where the executive can control legislative business a bill may be brought in by executive fiat.
US committee system 
|This section requires expansion. (March 2010)|
In the United States Congress, a system of committees considers law relating to each policy area jurisdictions. Thousands of bills are introduced in every session of Congress, and no single member can possibly be adequately informed on all the issues that arise. The committee system is a way to provide for specialization, or a division of the legislative labor. Sometimes called "little legislatures," committees usually have the final say on pieces of legislation. Committees only very rarely are deprived over control of a bill; although this kind of action is provided for in the rules of each chamber.
- By far the most important committees in Congress are the Standing Committees, permanent bodies that are established by the rules of each chamber of Congress and that continue from session to session.
- Select Committees are created for a limited time and for a specific legislative purpose. For example, a select committee may be formed to investigate a public problem, such as child nutrition or aging.
- A Joint Committee is formed by the concurrent action of both chambers of Congress and consists of members of each chamber. Joint Committees, which may be permanent or temporary, have dealt with the economy, taxation, and the Library of Congress.
- Conference Committees- No bill can be sent to the White House to be signed into law unless it passes through both chambers in original form. Sometimes called the "third house" of Congress, Conference Committees are in a position to make significant alterations to legislation and frequently become the focal point of policy debates.
- The House Rules Committee- Because of its special "gate-keeping" power over the terms on which legislation will reach the floor of the House of Representatives, the House Rules Committee holds a uniquely powerful position.
Passing a bill 
Bills are generally considered through a number of readings. This refers to the historic practice of the clerical officers of the legislature reading the contents of a bill to the legislature. While the bill is no longer read, the motions on the bill still refer to this practice.
In the British/Westminster system, a bill is read the first time when it is introduced. This is accompanied by an order that the bill be printed and considered again. At the second reading the general merits of the bill are considered – it is out of order to criticise a bill at this stage for technical defects in drafting. After the second reading the bill is referred to a committee, which considers the bill line by line proposing amendments. The committee reports to the legislature, at which stage further amendments are proposed. Finally a third reading debate at which the bill as amended is considered in its entirety. In a bicameral legislature the process is repeated in the other house, before the Bill is submitted to the executive for approval.
Bills passed by the legislature usually require the approval (often called Royal Assent, especially in constitutional monarchies) of the executive such as the monarch, president, or governor to become law.
In parliamentary systems, this is normally a formality (since the executive is under the de facto control of the legislature), although in rare cases approval may be refused or reserved.
In presidential systems, the need to receive approval can be used as a political tool by the executive, and its refusal is known as a veto. In presidential systems, the legislature often has the power to override the veto of the executive by means of a supermajority. Any branch at anytime may decline the proposed bill.
In constitutional monarchies, certain matters may be covered by a so-called royal prerogative. In the United Kingdom, for example, these include payments to the royal family, succession to the throne, and the monarch's exercise of prerogative powers. The legislature may have significantly less power to introduce bills on such issues and may require the approval of the monarch or government of the day. The Governor General will get the Queen to sign the bill and the bill becomes law.
Numbering of bills 
Legislatures give bills numbers as they progress.
In the United States, all bills originating in the House of Representatives begin with "H.R." and all bills originating from the Senate begin with an "S.". Every two years, at the start of odd-numbered years, the United States Congress recommences numbering from 1. This means that two different bills can have the same number. Each two-year span is called a congress, and each congress is divided into year-long periods called sessions.
In the United Kingdom, for example, the Coroners and Justice Act in 2009 started as Bill 9 in the House of Commons. Then it became Bill 72 on consideration by the Committee, after that it became House of Lords Bill 33. Then it became House of Lords Bill 77, returned to the House of Commons as Bill 160 before finally being passed as Act no. 29. Parliament recommences numbering from one at the beginning of each session. This means that two different bills may have the same number. Sessions of parliament usually last a year. They begin with the State Opening of Parliament, and end with Prorogation.
