At a World Jewish Congress conference in Jerusalem, the organisation's president Ronald Lauder challenged Israel's foreign minister Gideon Sa'ar.
"I'm not sure that a sanction of 12 months in this case - if we'd have forced the tribunal into that position - or a case of 'no fault' would have been a good outcome," said Wenzel."One would have compromised an important principle under the code. The other one, in our view, would have been an unduly harsh sanction."
Case resolutions have been allowed since 2021, and Wenzel said Wada had since struck 67 agreements.The code is set to change from 2027, meaning cases where players have failed tests but were deemed not to be at fault - like Sinner - could be punished from a reprimand to a two-year ban."In two years, Sinner would simply have had a slap on the wrist," one source from an anti-doping organisation told BBC Sport.
Some top players continue to believe Sinner has been given preferential treatment because of his status.Both the International Tennis Integrity Agency (ITIA) and Wada flatly reject any suggestion that is the case.
But it is clear Sinner - and five-time women's major champion Iga Swiatek, who received a one-month suspension last year after testing positive for heart medication trimetazidine - have benefitted from being able to pay top lawyers to act quickly.
"A majority of the players don't feel that it's fair," said 24-time Grand Slam champion Novak Djokovic.That was handed over on 31 January, and in early February the first "concrete discussions" began after the second approach.
But with Sinner always sure of his innocence and confident he would face no ban, would he accept a three-month suspension?His lawyer Singer said it was "quite tricky" to convince Sinner to take the offer.
"When I was saying 'well, look, maybe we should settle for three months', he was saying 'well, why would we do that if the first independent tribunal found it was no ban at all, why would I accept three months now?'," Singer said."My advice was 'one never knows what's going to happen at a hearing, we know that Wada are pushing for a year, if we don't accept their offer then they will go to court looking for a year and who knows what those three judges could do'.
