The Arbitration Committee did not open or close any cases this week, leaving three currently open.

• Piotrus 2: A second case involving alleged edit warring and other misconduct by Piotrus and other editors. Piotrus denies the allegations against him, and has suggested that the case may be a deliberate attempt to drive him from the site.

• SlimVirgin-Lar: A case brought by Thatcher, asking the committee to review the use of checkuser by Lar, in the light of comments by SlimVirgin (here, inter alia), alleging that he misused the tool. A finding of fact with the support of four arbitrators find that Lar's conduct "fell within the acceptable range of CheckUser discretion", and remedies reminding users to bring similar issues to appropriate dispute resolution processes rather than "public invective", and reminding CheckUser operators to abide strictly to the Wikimedia Foundation's privacy policy, have the support of three arbitrators, with none opposing.

• Sarah Palin protection wheel war: A case involving allegations of wheel-warring on the Sarah Palin article, over a dispute as to the merits of page protection being applied in respect of it. Remedies instructing the parties to follow the principles adopted in the case, admonishing Jossi and MZMcBride for their use of administrative tools in the dispute, and urging the community to continue discussions regarding the improvement of the biographies of living persons policy, have the support of six arbitrators. Remedies restricting Jossi and MZMcBride from unprotecting or reducing the edit-protection status of a biography of a living person for 90 days have the support of four arbitrators, with two abstaining. Remedies that would desysop the two, either temporarily or permanently, appear unlikely to pass at this time.
