Isn't the usa like Canada in that cities don't exist in the constitutional structure, they are basically creations of the state/province and as such can be wiped away with a simple ruling from the state/provincial legislature? Isn't that what one should do in this kind of situation, just pass legislation that revokes the current body's authority, fire all the committee members/representatives/whatever until you get down to base government, put in a transitional government committee on top of that that passes all new and improved ordinances and ensures their implementation before going to a vote 2-4 years down the road to replace themselves after the new status quo is entrenched? This would have the added benefit of getting the rest of the cities in line to do their jobs so they avoid the same fate.
