An extraordinary meeting of a community council may be called at any time by the chairman of the council.

If the chairman refuses to call an extraordinary meeting of the council after a requisition for that purpose, signed by two members of the council, has been presented to him, or if, without so refusing, the chairman does not call an extraordinary meeting within seven days after such a requisition has been presented to him, any two members of the council, on that refusal or on the expiration of those seven days, as the case may be, may forthwith convene an extraordinary meeting of the council.
