In a game described as the 'Deduction Derby' courtesy of both teams having received points penalties for breaching the Premier League's Profit and Sustainability regulations, goals from Idrissa Gueye and Dwight McNeil earned the Toffees a potentially-pivotal three points at Goodison Park.
As a result, 16th-placed Everton have moved four points clear of Forest who are a position lower, the East Midlands outfit remaining a point above the relegation zone.
During the contest on Merseyside, three penalty appeals went against Forest, all for incidents involving Everton's Ashley Young.
What happened?
The veteran wide player appeared to clip Giovanni Reyna inside the penalty area during the first half, only for VAR to deem that not enough contact had been made to overrule the initial decision made by the referee.
Moments before half time, Callum Hudson-Odoi's volleyed cutback hit the outstretched arm of Young, only for the close proximity to lead to no overrule occurring.
After half time, Young again became involved with Hudson-Odoi, the on-field referee and VAR both ruling that he had made a fair challenge despite a tangling of legs.
Once the full-time whistle had gone, it took Forest's social media account just five minutes to post their frustration over the aforementioned incidents.
While the official in question was not mentioned in Forest's statement, Stuart Attwell was the VAR official for this particular game.
As it stands, the PGMOL are yet to react to Forest's comments, but they come just a month after former Premier League referee Mark Clattenburg was appointed as the club's referee analyst.
