3.1 to develop an internationally agreed taxonomy for viruses;
3.2 to establish internationally agreed names for virus taxa;

In addition, any virologist may submit a taxonomic proposal or suggestion to the appropriate Virus Subcommittee Chair(s) following the procedures described below.Proposals shall be sent to the appropriate Virus Subcommittee Chair for consideration by that Virus Subcommittee and the appropriate Study Group(s). Proposals shall also be sent for consideration to all Study Groups and Virus Subcommittees whose interests might be affected by the taxonomic or nomenclatural changes proposed. Taxonomic proposals approved by any Virus Subcommittee, usually in consultation with a Study Group, shall be submitted to the Executive Committee by the Virus Subcommittee Chair for approval. Proposals approved by the Executive Committee shall be published on the ICTV web site and presented for ratification to the full ICTV membership by a ballot organized by the Officers.

Executive Committee decisions shall be made by a simple majority of Members voting. A quorum shall consist of the President or Vice-President, 1 Secretary and 9 other Executive Committee Members. Changes to the ICTV Statutes shall require the additional approval of the Virology Division of the IUMS (see Statute 11).
