Smaller assemblies can avoid the formalities of committing and reporting by considering a matter "as if" in a committee of the whole, or by considering it informally. Either option opens debate in the manner of the committee of the whole, but the presiding officer retains the chair. In the former case, also called a quasi-committee of the whole, all amendment adoptions are tentative and open debate ends when the assembly adopts a motion other than an amendment. The chair then announces the amendments that were adopted in quasi-committee, which are subject to a confirming vote. In the latter option, votes are binding on the assembly and any successful motion to dispose of the current main motion ends the informal debate.
