If a case goes to court and the factual instances produce inadequately reasoned results, the appeal remains the last possibility for correction. The admissibility requirements are strict; the argumentation on the merits requires profound knowledge of procedural law, substantive law and especially the law of appeal. Procedural and substantive objections can only be raised with some chance of success by those who know how to read and challenge judgments.

If legal recourse is exhausted, there is exceptionally another possibility: that of a state constitutional complaint or an appeal to the Federal Constitutional Court. This option must always be examined if fundamental rights or rights equivalent to fundamental rights are violated, whether by judgements of the court of last instance, incorrect searches, detention decisions or other coercive measures, or by criminal laws.
