(1) The decisions of the examining section are to be reasoned and a copy served on the parties ex officio; the copy need not be certified. Execution copies are made only upon application by one of the persons concerned and only in paper form. The decisions may also be delivered at the end of a hearing; sentences 1 and 2 remain unaffected. The decision need not be reasoned if only the applicant is party to the proceedings and the request is granted.
(2) Upon service of the decision, the parties are also to be instructed about the appeal which is available from the decision, about the authority with which the appeal is to be filed, the time limit for filing of the appeal and the fee payable. The time limit for filing the appeal (section 73 (2)) only begins to run if the parties have been instructed in accordance with sentence 1. If the instruction has not been given or was given incorrectly, filing of the appeal is only admissible within one year following service of the decision, except in cases where instruction was given in writing that an appeal was not available; section 123 applies accordingly.
