West Ham points deduction

[ATFC Seagull]

A point that the clubs who are complaining and talking of going to court about West Ham seem to have forgotten is that in 1983 when Steve Foster tried to take the FA to court to play in the Cup Final, the judge ruled that the FA were autonomous and that by signing to join, clubs had agreed to abide by the decisions taken by their governing body.

I would assume that this would still follow suit with The Premier League, by joining, the clubs had similarly given up their right to a legal challenge.

Is this possible? Is it legal to sign into a contract that denounces one's statutory rights? I was under the impression no, but I may be wrong there. Presumably any legal challenge will be under UK law, not the rules clubs have signed up to by joining the FA.
