The perception of first court procedure faults in the revision is only possible in a narrow frame. The supreme court has to pick up nullities of the first authority, if the court of appeal has not denied the presentation of nullities, and also no other decision about the relevant nullity exists. The fact that from the appeal court denied first instance lacks can not be checked by the supreme court is due to § 519 Code of civil procedure. These rules also find application in procedures, which are dominated from the investigation principle and in working/social-judicial procedures.Since § 519 Code of civil procedure is immediately applicable only on nullities, the jurisprudence and a part of the apprenticeship draw the following extent-conclusion: If already a nullity can not checked by the supreme court, after the court of appeal has denied the concerned nullity, this must count more than ever for less serious simple procedure faults. A great part of the apprenticeship tried to disprove this maxim; admittedly unsuccessfully, because the supreme court sticks to this jurisdiction.Simple procedure lacks caused by the first instance are not discernible in the third authority furthermore when they were not asserted in appeal proceedings. This also counts in working- and socials-judicial procedures. In procedures, which are dominated from the investigation-principle, procedure lacks caused by the first instance can be apprehended by the supreme court, although they were not claimed in appeal proceedings or the court of appeal has denied them.
