A committee of the whole is a meeting of a legislative or deliberative assembly using procedural rules that are based on those of a committee, except that in this case the committee includes all members of the assembly. As with other (standing) committees, the activities of a committee of the whole are limited to considering and making recommendations on matters that the assembly has referred to it; it cannot take up other matters or vote directly on the assembly's business. The purpose of a committee of the whole is to relax the usual limits on debate, allowing a more open exchange of views without the urgency of a final vote. Debates in a committee of the whole may be recorded but are often excluded from the assembly's minutes. After debating, the committee submits its conclusions to the assembly (that is, to itself) and business continues according to the normal rules.
In legislative assemblies in the Commonwealth of Nations, the committee stage of important bills is typically conducted by the committee of the whole, whereas lesser bills may be considered in smaller committees. Outside the Commonwealth (for example, in continental European parliaments), the practice of committees of the whole does not exist - meetings of the entire membership are held according to the plenary sitting's rules, and the section-by-section vote on bills occurs in the plenum of the chamber.

Australia
Since 1994, the Australian House of Representatives no longer has a committee of the whole in the same vein as other legislatures in the Commonwealth. After the second reading, bills that would have been considered in a committee of the whole prior to 1994 would now instead proceed to a "consideration in detail" stage in which amendments to the bill may be similarly considered. The key difference with this change is that amendments are now considered by the plenary of the chamber, which means that the usual Westminster parliamentary conventions on committee stages don't apply (e.g. the Speaker is permitted to chair the committee stage and may remain in the Speaker's chair) and there is no subsequent report stage. Bills may still be referred to other committees, including the then-newly established Federation Chamber (then called the "Main Committee"), in which case the usual committee procedures are unchanged.

In the Australian Senate, the committee of the whole remains in use for consideration of bills and is provided for by chapter 21 of the standing orders. It is presided over by the Chairman of Committees.

In the state and territorial legislatures, the "consideration in detail" method is used in the Australian Capital Territory Legislative Assembly, New South Wales Legislative Assembly, Northern Territory Legislative Assembly, Legislative Assembly of Queensland, Victorian Legislative Assembly and Western Australian Legislative Assembly. All other chambers retain the committee of the whole procedure.
Canada
In the House of Commons of Canada, a Committee of the Whole is chaired by the deputy speaker or the deputy chair of committees. 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 11, 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.
At the provincial and territorial level, committees of the whole continue to be frequently used by jurisdictions with smaller legislative assemblies.
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.
