Fait accompli actions, where actions are justified by virtue of being already carried out, and difficult to reverse, are inappropriate.

The following arbitration ruling was passed 10 to 0 at 23:50, 10 March 2008 (UTC):

Editors who are collectively or individually making large numbers of similar edits, and are apprised that those edits are controversial or disputed, are expected to attempt to resolve the dispute through discussion. It is inappropriate to use repetition or volume in order to present opponents with a fait accompli or to exhaust their ability to contest the change. This applies to many editors making a few edits each, as well as a few editors making many edits.
