As in several other Austrian procedural laws, the calculation of deadlines in administrative matters varies depending on the means of filing. Due to an amendment (BGBl. Nr. 44/2019) to the Federal Administrative Court Law (Bundesverwaltungsgerichtsgesetz), submissions filed electronically with the Federal Administrative Court shall be deemed to have been filed timely, even if they are filed after office hours. As recently as in 2015, the Supreme Administrative Court ruled that if electronic submission were received on the last day of a deadline outside office hours, they could be rejected.
