Referee John Beaton initially declined to give a spot-kick during stoppage time at Fir Park while the game was tied 2-2.
VAR Andrew Dallas intervened, prompting Beaton to review the pitchside monitor and reverse his decision.
Kelechi Iheanacho converted the 99th-minute penalty to secure a 3-2 victory for Celtic.
The outcome meant Celtic needed only a victory of any margin against Hearts on the final day to clinch the league title.
The panel confirmed that Beaton's initial on-field decision was correct and the VAR intervention was erroneous.
This marked the second reviewed decision that went against Hearts, following a previous unawarded penalty against Motherwell.
The penalty decision sparked intense backlash across Scottish football.
Hearts manager Derek McInnes voiced his strong displeasure regarding the late refereeing call, calling it "disgusting."
Motherwell player Elliot Watt expressed disbelief, describing it as "the worst VAR decision in history."
Former England striker Gary Lineker added his perspective, saying it "might be the worst VAR decision I've seen."
In contrast, Celtic manager Martin O'Neill defended the referee's final assessment, stating it "looks as if it's a pretty clear cut" decision.
O'Neill explained his view on what transpired during the aerial challenge: "he's given it for the handball, and also an elbow on top of that there as well."
