The structure and foundation of our court system is grounded that every person is entitled to a fair and swift trial. However, there have been those cases in which the law wasn't upheld and the defendant felt they didn't receive a just trial (often based on evidence, jury, court actions, or law). Furthermore, it's the person's right to appeal the outcome of a trial court's decision provided there's just cause. Regardless of the person's crime, it's their Constitutional right to receive fair treatment in the court of law based on the laws.

Critically discuss the legal basis that a person can appeal to a trial court's decision. Additionally, discuss the legal basis for pursuing a case in appeals court and how it differs from the legal basis for a case in the trial court.
