This case is not directly related to the hearing into Manchester City’s 115 charges for alleged breaches of the Premier League’s financial rules, which began last month.
City were charged and referred to an independent commission in February 2023 following a four-year investigation.
It is alleged City breached the Premier League’s financial rules between 2009 and 2018.
“I don’t think this will have too much of a direct impact but this will probably give Manchester City a slight bounce because they’ve been found to be correct in a couple of narrow areas,” said Leaf.
“But equally, I think the Premier League will be relieved, especially after the recent Leicester decision where their rulebook was heavily criticised by an esteemed panel.”
He was referring to Leicester’s successful appeal against an alleged breach of Premier League financial rules – which means they are set to avoid any punishment.
Leicester successfully argued that because their 2022-23 accounting period ended on 30 June, they were not longer bound by Premier League rules – because they had just been relegated to the Championship – and so could not be found in breach.
Leaf added: “The fact that the majority of the Premier League’s rules have been found to be lawful and OK will probably come as a relief to them.”
BBC Sport’s chief football news reporter Simon Stone said: “The fierce manner in which City have responded to the verdict, allied to the knowledge they are currently fighting the substantive issue of 115 financial breaches, suggests they have spotted a weakness in the Premier League’s regulations which they will look to exploit as far as they can.”
