Arabic to English Law/Patents Law (general) criminal

The term appears in a Jordanian court document as the person who has objected to a verdict made against him.

One translator translated this term as "objector," which doesn't seem like the appropriate legal terminology, but I could be wrong.

A related term is الحكم المعترض , which was translated as "objected verdict."

I would very much appreciate any advice on this matter as to the correct translation of these legal terms. Thank you!
