But the referee can also see/change where a mistake by OTHERS can be reversed. There is no OTHERS when Fidel makes his decisions...which depending on whether someone pissed on his corn flakes or not that morning, he change his mind.
So there is apples and oranges.
...but the referee also gets to pass judgement on his own calls too... To have a problem with one and not the other is hypocritical. Just because the referee also can overturn the decisions of others on the field to does not make it 'apples to oranges'.
