Committee of the Whole
A Committee of the Whole is a device in which a legislative body or other deliberative assembly is considered one large committee. All members of the legislative body are members of such a committee. This is usually done for the purposes of discussion and debate of the details of bills and other main motions.
In the House of Representatives, the equivalent device is termed the "Main Committee", and is used for uncontroversial matters. It is slightly different from most Committees of the Whole in that it generally meets separately from the House and has its own committee room, and can be as small as the Speaker, a member of the Government and a member of the Opposition. This device is rather new, having been introduced only in 1994.
In the Canadian House of Commons, a Committee of the Whole is when all the MPs sit in the chamber in one large committee. The committee is chaired by the deputy speaker or the deputy chair of committees. It uses committee rules rather than House procedures.
In the past, the Committee of the Whole considered a majority of bills, with few bills being sent to parliamentary committees. The increased workload of MPs has led to a decline in this use of the Committee of the Whole. Now the Committee of the Whole is used mostly for monetary bills and on rare occasions to expedite the passage of other legislation.
On June 11th 2008, Prime Minister Stephen Harper formally apologized in the House of Commons for the government's historical role in the Canadian residential school system. A Committee of the Whole was used, so that aboriginal leaders (who were not Members of Parliament) could be allowed to respond to the apology on the floor of the House. 
Hong Kong 
In the Legislative Council of Hong Kong, when the debate of the second reading resumes, members debate the general merits and principles of the bill. At the committee stage, the Legislative Council becomes 'a Committee of the whole Council' and goes through the bill clause by clause, making amendments where necessary. After the bill has passed through Committee with or without amendments, it proceeds to the third reading for passage by the Council.
United Kingdom 
In the House of Commons of the United Kingdom, the Committee of the Whole House is used instead of a standing committee for the clause-by-clause debate of important or contentious bills. The sitting is presided over by the Chairman of Ways and Means, rather than the Speaker of the House.
In the House of Lords, the Committee of the Whole House examines the majority of bills.
The Committee of the Whole House originated as a device by which to consider legislation without the presence of royal officers and without a formal record being made of the proceedings. The Speaker is considered to have duties both to the House and to the Crown. Thus, the House would resolve to form a committee, consisting of all the members, "Mr. Speaker and the Clerk excepted."
United States 
United States Congress 
In the United States House of Representatives, the Committee of the Whole is a device in which the House of Representatives is considered one large Congressional committee. The presiding officer is chosen by the Speaker of the House and is normally a member of the majority party who does not hold the chair of a standing committee.
Non-legislative use and variants 
Robert's Rules of Order states that the committee of the whole is suitable to large assemblies. The procedure is invoked by a motion to commit to the committee of the whole, or simply to go into a committee of the whole. The only motions in order in a committee of the whole are those to adopt a proposal for inclusion in the committee's report; to amend; to "rise and report"; as well as certain incidental motions and requests.
Variants of the committee of the whole are the quasi committee of the whole and to consider informally. The difference between a committee of the whole and a quasi committee of the whole is that in the latter, the presiding officer of the assembly remains in the chair and presides. Informal consideration simply removes the normal limitations on the number of times members can speak in debate.
The Standard Code of Parliamentary Procedure rejects both the committee of the whole and quasi committee of the whole procedures as being outdated, and instead recommends the motion to consider informally in their place.
