Let me jump to the conclusion - you use the wrong form in most of the case.
The term "Outside the jurisdiction of the tribunal (審裁處的司法管轄權範圍)" means the magistrate judge's award or order is made beyond his/her authority by the law.
For example - You are sued for $45,000. However, upon the trial, the fact presented showing the amount in dispute should be $55,000. The magistrate judge orders you to pay $55,000 and court fees. In this case, you will have 2 reasons for Form 9:
a. The magistrate judge's award is more than the limit of the Small Claim Tribunal ($50,000);
b. The magistrate judge's award is more than what the plaintiff (the person suing you) asks for.
In that case, the Court of First Instance (of the High Court), if accepted you appeal, can order a new trial or a modification of the award.
You should use Form 9 if there is a clearly legal error. Otherwise, you should use:
Form 8C - for the appeal of judgment other than the law; or
