The Arbitration Committee closed four cases this week.

A case against User:Stevertigo for inappropriate use of administrative powers has closed. Stevertigo must reconfirm himself at Wikipedia:Requests for adminship/Stevertigo. The dispute regarded Stevertigo's violation of the three-revert rule, and subsequently unblocking himself a number of times.

A case against -Ril- has ended this week. As a result, -Ril- has been banned for a month for removing other users' comments from discussions, and for an additional week for "incorrect speedy-deletion tagging". When the ban expires, -Ril- must adopt "an un-confusing signature." -Ril-'s signature, which was identical to the software signature for signing posts, caused problems when users copied -Ril-'s comments.

A case against Rktect has closed. The ruling bans Rktect from all articles relating to weights and measures indefinitely, and allows for bans of up to one week for violating this measure. Rktect was accused of creating many unsourced articles, and insertion of unsourced information into existing articles. Rktect also admitted to reverting people who reverted vandalism on these pages, "[to make] a point".

A case against ArmchairVexillologistDon has closed. As a result, ArmchairVexillologistDon has been banned for one year. ArmchairVexillologistDon was accused of personal attacks against other users.

The case was originally filed in December 2004, and closed in January 2005 due to ArmchairVexillologistDon's departure from Wikipedia. Upon his return, the case was reopened, but was closed again in September 2005, as the user who brought the request initially rescinded it. After an RfC against him, and upon a request by Zscout370, it was reopened this month.

A case was accepted this week against User:Jguk. It is in the evidence phase.

Requests against Copperchair and Silverback have each received 4 "accept" votes, the minimum number needed for cases to move forward.

Other cases against Ultramarine (user page), Maoririder (user page), Zephram Stark (user page), numerous editors on Bogdanov Affair, Everyking (user page), REX (user page), Rangerdude (user page), numerous editors on Ted Kennedy, numerous editors on Polygamy, and Lightbringer (user page), are in the evidence phase.

Cases against Onefortyone (user page), 12.144.5.2 (user page, a.k.a. Louis Epstein), BigDaddy777 (user page), Keetowah (user page), an IP dubbed DotSix, and Instantnood (user page) are in the voting phase.
