Premier League clubs have signed up to an anti-breakaway owner's charter.
All 20 agreed to the code, which was originally proposed in response to the now-defunct plans to form a European Super League.
It is hoped that the charter will keep the big six - who wanted to guarantee themselves European football each year - in check by declaring that sporting merit rather than a coefficient system will determine who qualifies.
It also continues the equal balloting system, where 14 votes out of 20 are needed to pass a new rule.
