City have denied the breaches, saying they are "simply not true".
The Euro 2020 championship, due to be staged in 12 cities across the continent, was postponed until June 11 to July 11 next year because of the novel coronavirus pandemic that shut down the sport in March. The organization's investigation determined City deliberately inflated a sponsorship value in order to break even under the regulations, with e-mails leaked to German outlet Der Spiegel revealing that club owner Sheikh Mansour's private-equity company covered almost £60 million of a £67.5 million deal.
CAS also said that the hearing is not open to the public and indicated it might be conducted via video conferencing because of the coronavirus-forced travel restrictions in place.
The UEFA is determined to complete the current Champions League 2019-20 season and is looking at August. The English champions have been accused of deceiving UEFA in order to comply with Financial Fair Play regulations.
An investigation was launched after leaked emails published past year by German magazine Der Spiegel as part of "Football Leaks".
Der Spiegel had reported that City created a shell company to hide tens of millions of dollars which they used for recruiting players.
Announcing its verdict three months ago, UEFA said the Abu Dhabi-owned club was guilty of "overstating its sponsorship revenue in its accounts and in the break-even information submitted to UEFA between 2012 and 2016".
City also failed to cooperate in the investigation.
With counted exceptions like France, Belgium and Scotland, the domestic leagues are still looking for a resumption date with the aim of ending the season as soon as possible and making room for the Champions League. They also face Newcastle United in the quarter-final of the FA Cup. However, if CAS stick to their original ruling, it would make for an intriguing sub-plot for the end of the Premier League season.
The draft calendar would see the Europa League start up on 6 August, with the Champions League getting underway again on Saturday 8 August.
