that example has an objective answer, same for puck did go in, or offside, was it goaltender interference, that can become quickly subjective, without an actual answer that exist to be found by a scientific process.
Ok, since you clearly do not know how anything works in real live, here is a short explanation for you:
When we (humans) need to establish an objective fact we use several ways. Most common once - numbers and / or experts.
So, facing the problem of high speed of NHL games we established an expert body - the situation room in Toronto.
Therefore, a decision made by refs in the room is
an established objective fact.
What you think about it - is
your subjective personal opinion. And it is irrelevant since the fact is already declared by the experts.
In order to overcome any objective fact established by group of experts - you would need a bigger group of experts or better experts or noticeable advancement in science and technology.
Do you have any of these things? Obviously not.
