Both the plaintiff and the defendant are entitled to file an appeal if they think that there was in error in the original judgment. All rules regarding when and how the appeal is filed must be adhered to. For this reason, it is not a good idea to attempt an appeal without the assistance of an attorney.
If a review on appeal is granted, the judge will decide either to enforce the original judgment or not. If it is not enforced, it may be reversed or the case may be sent down for a new hearing. The outcome depends on the reason(s) forwarded for the appeal, and the judgment of the court regarding those reasons.
I hope this answers your questions.
