I recently noticed at Meta - and was a bit surprised - that the BoardVote extension has been used in elections to the Arbitration Committee att English Wikipedia. Since several other Wikipedias also have arbitration committées, but there is no note of these elections can be found on http://meta.wikimedia.org/wiki/Election_officials_2006 where the elections to the English Arc Coms are listed along with the elections to the Wikimedia Foundation Board of Trustees, I suppose the other arbitration committees have been elected openly on the wiki, the way administrators are normally chosen.
Why did English Wikipedia choses to have secret ballots in the election to their arb com? Why have the other wikipedias chosen not to?
On the more general scale: Why should votes for adminship be open, and votes to the Board of Trustees secret ballot? Where on the scale between these two types of elections do we find elections for an arbitration committee?
