Principle Statement

The court is required to examine thoroughly the grounds of appeal together with their particulars in order to see whether any of the grounds reveal a misunderstanding of the law by the lower court or a misapplication of the law to the facts already proved or admitted in which case it would be a question of law. Where, however, the ground is such that would require questioning the evaluation of facts by the lower court before the application of the law, that would amount to question of mixed law and fact.
