Any procedural questions raised by the jury should be referred to the Mayor who will be responsible for ensuring that hearings conform to the by-laws of the Charter.
Jn, I see you've eliminated the choice of no one overseeing hearings. I would prefer this to the Mayor overseeing them.
Maybe it will turn out that there are very few hearings and very few problems with them. If there are consistent problems, then the membership will recognize the need for procedural oversight of hearings, and the Charter can be amended to create that office.
Recognizing the need, failing to institute the office, and subsequently assigning the duties to (IMO) the wrong person is a completely unsatisfactory solution to me (so I will vote against the text).
