Mooney was booked on video evidence by the league's video reporting officer Ian Robinson but had controlling field umpire Michael Vozzo to thank for his acquittal.
Vozzo, who paid a free kick and a 50 metre penalty against Mooney at the time of the incident against St Kilda's Leigh Montagna which led to a goal for the Saints, told the tribunal on Tuesday night that even after watching video footage of the incident he still would not have laid a report.
When asked whether he felt the incident was reportable by tribunal chairman Brian Collis; Vozzo replied: "Certainly not."
"I don't believe the contact was forceful and I don't believe contact was made to the head of the player," Vozzo said.
The tribunal accepted Vozzo's evidence and wasted little time clearing the in-form Mooney, who is now free to continue to help Geelong's bid for a top four finish.
