No. Appeals are not an opportunity to have your entire case re-heard or re-tried by the appeal court. Only in very rare cases, where you make a special application, will you be allowed to present new evidence to the appeal court.
When you appear in appeal court, you must speak about the legal errors that you are alleging the judge made when initially hearing your case, using all the information and facts of the initial hearing. You must give legal reasons and make technical legal arguments about the errors you believe were made.
This process is very difficult to do, especially for those who do not have legal training. Decisions to file an appeal should be made with the help of legal advice. Remember that you may have to pay costs to the other person if the appeal is not successful.
