The verdict has been announced in Manchester City's legal case against the Premier League over its associated party transaction (APT) rules.
City had some complaints upheld, with two aspects of the APT rules deemed unlawful by a tribunal.
But the Premier League says the tribunal rejected the majority of Manchester City's challenges and "endorsed the overall objectives, framework and decision-making of the APT system".
APTs are aimed at the value of sponsorship deals with companies linked to clubs' owners.
This case is not directly related to the Premier League disciplinary commission which will hear 115 charges against City for allegedly breaching its financial regulations, some of which date back to 2009.
