Manchester City have been found guilty of 114 of the 115 Premier League charges brought against them following an independent commission’s investigation into alleged financial-rule breaches, in a landmark ruling that could reshape English football’s regulatory landscape.

The Premier League confirmed the outcome on Tuesday, ending years of uncertainty around the most significant disciplinary case in the competition’s history. However, the matter is far from concluded: City have until Friday, October 2, to formally lodge an appeal against the commission’s findings, while a separate process will determine the sanctions, if any, to be imposed on the club.

The commission’s decision relates to allegations spanning a near-decade from the 2009-10 season to 2017-18, a period in which Manchester City established themselves as one of English football’s dominant forces. The club was initially referred to an independent commission by the Premier League in February 2023 following a four-year investigation, although the allegations covered financial reporting and cooperation issues over a much longer timeframe.

According to reports on the Premier League’s formal announcement, City were found guilty of all financial charges and all but one allegation related to the club’s failure to cooperate with the league’s investigation. The ruling found that City had breached rules concerning financial information, including spending limits, the accuracy of accounts and reported revenue. The findings also included allegations involving contracts and sponsorship arrangements.

Premier League chief executive Richard Masters described the ruling as a defining moment for the competition and its ability to regulate clubs.

“The core decision establishes the facts of what happened at Manchester City during this period,” Masters said in the Premier League’s statement. “It details how the club systematically broke Premier League Rules for nearly a decade.”

Masters added that the verdict vindicated the Premier League’s decision to pursue the case and underlined its duty to uphold regulations designed to ensure competitive balance.

“It is a key responsibility of the Premier League to ensure that the rules, approved by the clubs themselves, are upheld to protect the integrity of the competition,” he said. “It is paramount that the League remains competitive and fair for all clubs and for the fans. We take that role extremely seriously.”

The Premier League chief executive called the case and its outcome “the most significant in Premier League history”, while stressing that an important phase remains unresolved: the decision on punishment.

“There are elements of the case that remain to be decided, including, importantly, what sanction must follow for these breaches,” Masters said. “Now we have the Commission’s decision, we are committed to moving swiftly through the remainder of the process, to provide certainty for the league, our clubs and fans.”

That distinction is crucial. The independent commission has ruled on the allegations, but no sporting or financial sanction has yet been imposed. The possible range of penalties under Premier League rules is broad and could include fines, points deductions, transfer restrictions or, in the most severe scenario, expulsion from the competition. Any final punishment would be subject to further legal and regulatory scrutiny.

Manchester City have responded forcefully to the verdict, maintaining their innocence and confirming their intention to use the available appeal process.

“The club is innocent of the accusations made by the Premier League and a comprehensive body of irrefutable evidence exists in support of all of its positions, relating to this case,” City said in their statement. “The Club will therefore be relentless, and where necessary proactive, in any and all appropriate regulatory and legal forums.”

The reigning English champions said they would challenge the decision because they believe the independent commission’s opinion contains “clear material errors, of law, principle and fact” and is therefore “unsafe”. City also said they remain restricted in what they can say publicly while proceedings continue.

“Manchester City FC will now pursue the appeal avenues open to it,” the club said. “The Premier League process remains ongoing, with significant elements uncompleted.”

City further questioned the Premier League’s conduct, reiterating concerns they had raised when the charges were first announced in February 2023.

“The Club has diligently respected due process for eight years on the basis that the Premier League Board and Executive would behave as an independent, impartial and fair-minded regulator, free from partisan influence,” City said.

The original case centred on allegations that City failed to provide accurate financial information giving a “true and fair view” of income, particularly sponsorship revenue, and operating costs over several seasons. The Premier League’s referral also included accusations of non-cooperation with the investigation. City have consistently denied wrongdoing.

The hearing itself began in September 2024 and concluded in December after nearly three months, with the case heard by a three-person independent commission. The length and complexity of the process have fuelled intense debate across English football, with rival clubs, supporters and football-finance experts waiting for clarity over the consequences.

City’s success on the pitch during the period covered by the investigation adds another layer to the case. Between 2009 and 2018, the club won three Premier League titles, three League Cups and an FA Cup, beginning a sustained era of domestic dominance following the 2008 takeover by Abu Dhabi United Group. Since then, City has won eight Premier League titles, as well as the UEFA Champions League, four FA Cups and seven League Cups.

The club has previously successfully challenged a major financial ruling. In 2020, UEFA imposed a two-year Champions League ban on City after finding that sponsorship income had been overstated between 2012 and 2016. That ban was overturned by the Court of Arbitration for Sport, although City were fined for failing to cooperate with UEFA’s investigation.

The Premier League case is separate and is being handled within its own judicial framework. The immediate focus now is on whether City submit their appeal before Friday’s deadline. The appeal process could determine which of the 115 original charges remain upheld and influence the next stage of the sanction proceedings.

Other Premier League clubs are also closely monitoring developments. Reports indicated that some clubs had already sought legal advice over whether compensation claims could arise from the outcome, though any such action would depend on how the appeal and sanction processes develops.

For Manchester City, the verdict represents an unprecedented challenge to a club whose modern era has been defined by trophies, elite recruitment and sustained performance. For the Premier League, it is a major test of whether its rules can be enforced consistently against its biggest and most powerful members.

The commission’s finding has delivered a historic verdict, but it has not delivered a final resolution. City’s expected appeal, the decision on sanctions and the possibility of further legal action mean the consequences of the case will continue to hang over English football long after Friday’s filing deadline.
