[QUOTE=la bazzle;228151](b) Promotion and Relegation shall be COMPULSORY between ZFL Leagues 1,2,3.
(c) Promotion and Relegation between ZF League 1 and ZFL Premier League will be based on Premiership and the Club’s ability to suit ZPL criteria. This will be determined by the Joint Board Panel and the Zone Association ZFL Competition Administrator each season.

Well never knew or didn't really pay much attention to that section, it hasn't stopped anyone in the past from rising to ZPL as long as I can remember.
