Well, the charges were only made on 25th July 2023.
Joe Lewis ceased to be a "Person with significant control" of Spurs in October 2022 - some time before the charges were made.
He bought a controlling interest in Spur in 2001, the crimes he has pleaded guilty to took place between 2013 and 2021.
In this instance, I'm not sure it's fair to criticise the Premier League for something he did 12 years after acquiring the football club.
