As a result of the case, remedies were enacted banning Boisseau and others attributed with Musik Fabrik from editing articles relating to their work, and placing Boisseau on probation and civility parole.

• RPJ: Various users allege that RPJ edits disruptively (although in good faith) on various articles related to conspiracy theories, such as John F. Kennedy Assassination. In response, he denies the allegations, and raised some "practical concerns about arbitration", which seem to regard the legitimacy of the Arbitration Committee bindingly to resolve disputes.

• Iran-Iraq War: A case referred by the mediation committee regarding a dispute on the Iran-Iraq War page.

• Konstable: A case involving the actions of Konstable, an administrator who left the project, but then returned and created an alternative account, which some allege was used for disruption.

• Hkelkar: A case involving the actions of Hkelkar, a probable sockpuppet of Subhash bose, on various articles.

• Protecting children's privacy: A case involving a policy proposal on the Wikipedia:Protecting children's privacy page. The committee is being asked to make a ruling as to the consensus requirements for the adoption of new policy. Fred Bauder has proposed remedies establishing the right of children to edit on Wikipedia if they do not disclose their age, but that if they do the information should be deleted.

• Non-Notability: A case regarding actions on Wikipedia:Non-notability (not to be confused with Wikipedia:Notability). Fred Bauder has proposed a remedy, which is supported by SimonP, allowing Fresheneesz to be placed on probation if he "continues to disrupt policy pages".

• Bowling for Columbine: A case involving the actions of Schrodinger82 and others on the Bowling for Columbine article, and in particular his disputed removal of some criticism of the film.

• Pseudoscience: A case involving the actions of ScienceApologist, Ian Tresman and others, involving the insertion and removal of so-called "pseudoscience" on various articles. Fred Bauder has proposed various remedies, most of which were opposed by Dmcdevit and Charles Matthews, but among those supported or not yet voted on are remedies placing Tommysun on probation, and banning Elerner from various articles.

• Rachel Marsden: A case involving the actions of Arthur Ellis, Rachel Marsden, Bucketsofg and others on the Rachel Marsden page. Marsden and Ellis allege that the page contains inaccurate and libellous material, and that this has been protected on the page by various admins.
