OK, I got a call and e-mail back. This is going to be one for the record books.
Please talk to them yourself, if you're in C66.
The really big picture seems to be that the Secretary Treasurer was working on his perspective on the recall, along the lines of the letter the other two reps had produced. He submitted a draft to the Chairman for distribution on Monday, and the Chairman evidently was not comfortable with the draft. Several edits were made over the week, per his requests, but he still evidently felt the letter was (I'm paraphrasing) too political. An MEC voting rep can't be stopped from writing to membership, but otherwise communications to the group are channeled through the Chairman (I didn't know this). The FO rep doesn't think it's in the best interest of the council to suppress communications from another elected rep, so he used his authority. He didn't take any position on the letter itself, other than to say he didn't see anything detrimental to the Council in it.
