“In order to decide whether a person carries on business on his own account it is necessary to consider many different aspects of that person’s work activity. This is not a mechanical exercise of running through items on a check list to see whether they are present in, or absent from, a given situation. The object of the exercise is to paint a picture from the accumulation of detail. The overall effect can only be appreciated by standing back from the detailed picture which has been painted, by viewing it from a distance and by making an informed, considered, qualitative appreciation of the whole. It is a matter of evaluation of the overall effect of the detail, which is not necessarily the same as the sum total of the individual details. Not all details are of equal weight or importance in any given situation. The details may also vary in importance from one situation to another.”
“The question for the court or tribunal is whether, judged objectively, the parties intended when reaching their agreement to create a relationship of employment. That intention is to be judged by the contract and the circumstances in which it was made. To be relevant to that issue any circumstance must be one which is known, or could be reasonably be supposed to be known, to both parties (emphasis added).”
