A criminal appeal is a formal request to rehear a case that has already been decided -- a request that a new court reconsider the decision of the first court. When one or both sides of a case that has already been decided think there was a mistake made at trial, they can file an appeal. An appeal is entirely different than a jury trial. There is no testimony taken. The court of appeals decides the case entirely upon the written briefs filed by your attorney and the offie of the Attorney General who represents the prosecution and asks that the conviction be upheld.
Garrett Park is a town in Montgomery County, Maryland. It was named for a former president of the Baltimore and Ohio Railroad, but whether specifically for John Garrett or Robert W. Garrett is a matter of some disagreement between sources. The population was 917 at the 2000 census. Garrett Park is home to Garrett Park Elementary School, just outside the town proper.
