City Changing the Rules?

Boca Teeca residents recently received a notice that on 4/9/15 there will be another hearing by the Planning & Zoning advisory board on the request for an extension of the development approvals that are scheduled to expire on 4/12/15.  How can the city council consider this P&Z board recommendation AFTER the 4/12 expiration? - since there are no scheduled meetings of the council between 4/9 & 4/12

It appears that the city staff (city manager or city attorney or other internal city employees) has determined that the development approvals do not expire on 4/12/15 afterall.  Is there any wonder that the residents of Boca Raton do not trust the city leaders when clearly defined dates for expiration of prior approvals are open to loopholes that benefit the friends of the city?
