An appeal is a special written application asking to have a higher court determine if errors were made in a decision or order issued by a lower court or in the way the hearing or trial was heard at the lower court. An appeal can be filed if a party believes that the judge who heard their case applied the wrong law to the case or applied the law in the wrong way to the facts of the case. In very rare circumstances, you may be able to argue that the judge made an error in deciding the facts of the case, but this kind of error must be extreme (palpable and overriding).
Only certain kinds of errors can be appealed.
You do not file an appeal simply because you didn’t like the decision that was made. You also do not file an appeal to have another chance to present your case or do a better job of presenting your case.
