Cutting through the fog, City’s legal team have made their position quite clear. In its present guise, APT is unlawful in the main, therefore unenforceable, which renders it in effect null & void.
After the initial "we won" bluster from the PL, Masters withdrew from his golf day with the PL's broadcasting partners, & further had to defer the PL's hastily called meeting for 12 days, whilst they reconsidered their initial claim that “a small number of discrete elements” of APT (which doesn’t comply with competition law), “can quickly and effectively be remedied by the league and clubs”.
Simon Cliff has spoken, & judging by the PL's later position of them now “taking the necessary time” to decide how to respond to the verdict, I'd rather go with the considered view of the City lawyer who was in the room, than random opinion.
APT in its present guise is unlawful, unfair & unreasonable, therefore unenforceable, so in effect it's legally null and void.
