Appeals from appellate decrees

In any second appeal, the High Court may, if the evidence on the record is sufficient, determine any issue necessary for the disposal of the appeal,—

(a) which has not been determined by the lower Appellate Court or both by the Court of first instance and the lower Appellate Court, or

(b) which has been wrongly determined by such Court or Courts by reason of a decision on such question of law as is referred to in section 100.]
