I too recall a letter from one of the elders (Mordaunt? Medugnats? Not 100% on which) kicking him out and declaring him excommunicated. But no, there was not a vote by the elders to my understanding (not that I would not, know being an elder, but it wasn't announced as 'vote from the elders', just as a church-wide order from an elder). Thus, Jonsu did protest the lack of voting.
TL;DR: elder declared Leopold excommunicated the church; elders didn't vote.
It would have been Mordaunt who was regent at the time.
