Wikipedia:Third opinion

The third opinion process is neither mandatory nor binding. This is a voluntary, nonbinding, informal process, enabling two editors involved in a current dispute to seek advice from an uninvolved third party.

Third opinion (3O) is a means to request an outside opinion in a content or sourcing disagreement between two editors. When two editors do not agree, either editor may list a discussion here to seek a third opinion. The third opinion process requires observance of good faith and civility from both editors during the discussion in order to be successful.

The less formal nature of the third opinion process is a major advantage over other methods of resolving disputes. For more complex disputes that involve more than two editors, or that cannot be resolved through talk page discussion, editors should follow the other steps in the dispute resolution process such as the dispute resolution noticeboard or request for comment.
