A test to identify a key fact is to ask the question, "If this fact is changed, would the outcome of the application of the law be affected or changed?"

Key facts are the ones that affect a process in a way that they cannot be assessed to change.

IF it is fundamentally affected then it is evident that it is one of the key facts.
