Kirby proposed changing the executive powers language in Section 3 of the City Charter citing the recent action by the city council to require all contracts be approved by the city council as evidence that the city council was moving into the mayor's administrative duties under the charter. The language he proposed to the Charter Revision Commission and which the CRC approved unanimously at their January 4, 2012 meeting is as follows (new additional language is underlined):
Section 3.01 Executive Power.
The executive and administrative power of the city shall be vested in a mayor. The mayor's executive and administrative power shall include, but not be limited to the following: appointing directors, hiring employees, supervising staff, disciplining employees, terminating employees, negotiating and awarding contracts, supervising the delivery of services, administration of the budget, administration of the Capital Plan, preparing the budget, preparing the Capital Plan, assignment of duties and responsibilities of staff, and enforcement of city ordinances.
Here is the summary presented in those Kirby dog and pony shows back in 1994:

Isn't it interesting that back "then," Kirby's side by side comparison stated that the council acts as an independent control over those who spend?
So, why add all this language that now includes the language "negotiating and approving contracts?" Especially after the council took official action to approve contracts against the position of the mayor.
It sure seems a little suspect that Mr. Kirby pops back up right after the city council acts to approve contracts at a regularly scheduled city council meeting to push the mayor's agenda which was is in disagreement with the city council.
Joe Kirby's then and now - why now?
