In fact I remember a time during Spring Break when only two of us showed and the meeting was nixed as soon as the roll call codified a lack of quorum. The matter is referenced in Section 14-1 of the Charter
[Amended 7-11-1967; 8-25-1970; 6-27-1977; 3-15-1982; 3-17-1986; 11-6-1989; 5-7-2007]
Regular meetings of the City Council shall be held in the Council Chambers at the Municipal Building every first and third Monday of the month, at 7:00 p.m., unless such Monday is a legal holiday, and in such event the meetings shall take place on the following day at the same hour.
Special meetings, adjourned meetings and work sessions can and do occur at different times but the two regular meetings are fixed by law, or had been up until now. I know it's semantics and not a big deal to anyone but a stickler for such things.
Like those who consider the Constitution a "living document" versus those who abide by the literal view expressed by the framers.
But times change and a new Council apparently has the latitude to not adhere to the Charter. I would have recommended an amendment to allow say the Mayor to reschedule regular meetings with sufficient notice, but that's not how it reads now.
