The rules applicable to appeals define how to review judgments in order to find errors of law. A court of appeal reviews a judgment to see whether it infringes on any procedural or material law provisions. A particularly important procedure is an appeal to the first criminal division as this is the sole remedy against a sentence which is available to an affected person in this context.
In addition to practical experience, successfully lodging an appeal requires precise knowledge of procedural rules and, in particular, of the stringent formal requirements to be met and the high number of supreme court rulings.
