A court has a duty to disallow a question which is not relevant to the proceedings; but a question which is relevant can freely be put to a witness and must be answered, although the weight to be attached to the answer is an entirely different matter. Thus relevance and admissibility are closely knit together while the question of weight appertains to the province of evaluation and should, as always, be kept in separate compartment.
