The documents also confirm that in March 2020 nine Premier League clubs filed an application for intervention to Cas "opposing any possible application by City" to be allowed to play in Europe next season pending an appeal decision.
The Court of Arbitration for Sports admitted that Manchester City had shown "blatant disregard" for UEFA's investigation into alleged Financial Fair Play beeches and did not produce enough evidence.
However, CAS found in City's favour that the seven emails had been taken out of context, thereby reversing the sanction handed by the football body.
But noting that the charges of alleged concealment of equity funding were more significant violations, the CAS said "based on the evidence, the panel can not reach the conclusion that disguised funding was paid to City".
The former Premier League champions have always firmly denied the allegations, saying that the claims are part of a "clear and organised" assault on the club's reputation, before adding that the latest allegations are part of "a cynical attempt to publicly re-litigate".
Manchester City's two-season ban from European competitions was overturned on appeal by the Court of Arbitration for Sport.
"The majority of the panel finds that MCFC's failure to cooperate with the CFCB's investigation is a severe breach and that MCFC is to be seriously reproached for obstructing the CFCB's investigations", Cas said referencing Uefa's CFCB.
The club were accused of deliberately inflating the value of income from Emirati sponsors Etisalat and Etihad Airways to meet Uefa's FFP regulations, which limits losses clubs can incur to spend on player transfer fees and wages.
Manchester City's fortunes have been turned drastically since a takeover from Shiekh Mansour, a member of the Abu Dhabi royal family, in 2008.
City did not supply Uefa's investigation with the original emails related to the leaked documents but CAS also noted that Uefa did not "pursue" that evidence before the hearing.
Explaining the decision to overturn the ban, CAS said that the charge of "dishonest concealment of equity", which was unproven, was more serious than the failure to co-operate with UEFA's investigation.
