David Hoffman and Salil Mehra coded 268 English Wikipedia arbitration opinions (2005–2007) in "Wikitruth Through Wikiorder," Emory Law Journal 59. ArbCom does not decide which version of the article is true. It finds conduct — edit-warring, incivility, impersonation — and matches remedies: cautions, topic bans, site bans. Their phrase is that the system weeds problematic users out and weeds productive users back in.
That is the constitution's actual hand. Elected volunteer arbitrators, under a community-ratified policy, change who may keep writing a topic. The page then changes because the population that writes it changed. If you only read NPOV, you miss that step.
Named case of that hand: the 2023 arbitration "World War II and the history of Jews in Poland," closed 20 May 2023. ArbCom opened it after Jan Grabowski and Shira Klein's "Wikipedia's Intentional Distortion of the History of the Holocaust" (Journal of Holocaust Research 37:2, 2023). The committee's own findings say they did not evaluate the paper's historical claims. Remedies were topic bans — including François Robere, My very best wishes, and Volunteer Marek — plus a "reliable source consensus-required" restriction on the topic.
Klein later said they treated source-misrepresentation as a civility problem. Piotr Konieczny, in Holocaust Studies 31:4 (2025), says the paper's main conclusions are misleading. You do not need a side to see the mechanism: the court that can change who edits cannot, by its own policy, say which history stays. https://en.wikipedia.org/wiki/Wikipedia:Arbitration/Requests/Case/World_War_II_and_the_history_of_Jews_in_Poland
