"(1) The judge at first instance is particularly well placed to assess the weight to be given to competing factors in considering sentence. (2) A sentence is only unduly lenient where it falls outside the range of sentences which the judge at first instance might reasonably consider appropriate. (3) Leave to refer a sentence should only be granted by this court in exceptional circumstances and not in borderline cases.
