After a four-year investigation, the Premier League has charged Manchester City with more than 100 financial rule violations.
Between 2009 and 2018, it reported the club to a separate body for suspected rule violations.
Additionally, it charged City with failing to cooperate ever since the investigation's opening in December 2018.
After being acquired by the Abu Dhabi United Group in 2008, City won the Premier League for the sixth time last season.
The commission has the authority to penalize clubs by kicking them out of the Premier League, fining them, or deducting points from their standing.
The Premier League said in a statement that City had broken the regulations by failing to present "accurate financial information that gives a truthful and fair view of the club's financial position."
This data was about the club's revenue, which included sponsorship money and running expenses.
Additional alleged violations include regulations mandating full disclosure of manager compensation during Roberto Mancini's tenure as manager from 2009–10 to 2012–13 and player compensation from 2010–11 to 2015–16.
The Premier League claimed that from 2013–14 to 2017–18, City violated both Premier League rules on sustainability and profitability as well as Uefa laws, particularly Financial Fair Play (FFP).
Uefa, the organization that governs European football, determined in 2020 that City had violated FFP rules "seriously" between 2012 and 2016.
The Court of Arbitration for Sport (Cas) reversed a two-year suspension from European tournaments later that year.
After German tabloid Der Spiegel released stolen papers in November 2018 indicating the club had overstated the worth of a sponsorship arrangement, Uefa launched its inquiry against City.
The panel, which is led by Murray Rosen KC, will conduct its hearings in secrecy.
