The Premier League’s rules governing sponsorship deals from the period between 2021 and 2024 are “void and unenforceable”, a tribunal has ruled.

Last year, an independent arbitration panel found against aspects of the league’s Associated Party Transaction regulations (APTs) after a lawsuit instigated by Manchester City.

The Premier League says the tribunal’s ruling does not impact the “valid operation” of current APT rules, which it believes are still “valid and enforceable” and remain in “full force”.

The rules were formed by the Premier League to prevent clubs from profiting from commercial deals with companies linked to their owners that are deemed above “fair market value”.

In November, the Premier League voted through amendments to the rules despite opposition from Newcastle, Nottingham Forest and Aston Villa, as well as City.

Friday’s ruling is not in judgement of the November amendments which still stand but are the subject of a legal challenge.

The conclusion of the tribunal reads: “In the first partial final award it was declared that the APT rules and amended APT rules were unlawful in three respects.

“There now arises for decision the question whether those three respects can be severed from the remaining APT rules so that those remaining APT rules are valid and enforceable.

“The three respects in which the APT rules and amended APT rules were unlawful cannot be severed with the result that the APT rules as a whole are void and unenforceable.”

In a statement the Premier League said: “This decision expressly does not impact the valid operation of the new rules.

“The tribunal has made no findings as to the validity and effectiveness of the new rules. The tribunal states that whether its decision has any benefit to the club, therefore, depends on whether the new APT rules are found to be lawful as part of the second challenge issued by the club last month.

“The League continues to believe that the new APT Rules are valid and enforceable and is pressing for an expeditious resolution of this matter.

“The new APT rules are in full force and clubs remain required to comply with all aspects of the system, including to submit shareholder loans to the Premier League for fair market value assessment.”
