On January 1st, 2014, the system of administrative jurisdiction in Austria was amended considerably (Federal Gazette I 2012/51) within the field of legal protection. This modification manifested itself in the establishment of a new structure of administrative jurisdiction. Many institutions, e.g. the court of asylum or the independent senates of administration in the provinces, have been abolished and their areas of responsibilities have been undertaken by the federal and provincial administrative tribunals. This diploma thesis focuses mainly on how the amendment has changed the dealings with administrative and judicial delay relating to the legitimisation of petitions and legal standing respectively. To show the differences, a comparison is made between the old and new legal status of the delay complaints procedure by elaborating on the procedural requirements necessary for the admissibility of the complaints. As part of this analysis, the now limited scope of devolution application will be further described. Moreover, the newly created instrument for legal protection against judicial delay, the petition for setting a deadline, is illustrated. At the end of the thesis, both procedures will be analyzed starting from the premise that more than just one party is included in the proceedings.
