We won't know the outcome yet, but the club/legal team have clearly walked away feeling very confident that their evidence has dismissed the charges.
I'd imagine it was something along the below lines, but dragged across the other charges and over a few days/weeks (clearly I'm exaggerating slightly).
PL: They submitted false accounts based on inflated revenues, see emails provided as evidence.
City: Here are the emails, with context and here are the people referenced in the emails who can confirm that the allegation isn't true.
PL: That's all we've got.
Lawyers: I think we're okay on that group of charges.
