Generally speaking, any judgment issued by the trial court can be appealed. Sometimes there will be a partial judgment that does not dispose of all aspects of a case; those can be appealed only under special circumstances.

Some orders (i.e., rulings made by the trial court before the trial is completed) are also appealable, but most orders cannot be appealed until there is a judgment. Sometimes orders can be challenged by a special appellate procedure called a Writ Petition. The major difference between an appeal and a writ petition is that the Court of Appeal can - and usually does - deny the Writ Petition without considering the issues raised.
