As I understand it after reading a bit about the background, it's taken 4 years for the PL to finally charge them because City have done absolutely everything to derail the investigation, ignoring requests for documents appealing through various courts claiming they won't get a fair hearing, various injuctions to keep it out of the public domain eventually ending up in the court of appeal in front of 3 of the UKs most senior judges who expressed dismay at how long the whole process has taken and ultimately ruled against City saying it was of considerable public interest.
They did exactly the same with UEFA,but this time there is no time barring and no appeal to CAS.No doubt they won't co operate taking it to the absolute limit legally and depending on the punishment appeal although that would mean a fresh panel not the courts.
I think they know their bang to rights on a lot of it,hence the constant delaying and secrecy tactics,so they'll just try and use every trick in the book to let it rumble on for years.
Horrible fake club.
