The American judicial system is pure theater. You used to be able to appeal forever. Then the government decided that was too expensive, so they changed it to like 7 days. Then that was too extreme of a limit from 'forever' so they compromised on 14 days. Your right to appeal expires in 14 days in the US. Also during those 14 days you are most likely in a detention center, or being transferred across the nation to a prison, so good luck researching/writing an appeal in those 14 days.
