What court order can be appealed?

Answer

One of the mechanisms built into the U.S. justice system is a system to deal with appeals. Basically, any court order (except one by the Supreme Court) can be appealed. But it's an uphill battle. After all, one is seeking to have the order of a judge (or panel of judges) set aside. The basis for the appeal must have merit or an appellate court will reject it outright. If this happens, there's always another level of appeal, but the slope gets even steeper. (Remember, it's an uphill battle.)
