Article 10 Time limits for action 1.

The interested parry may, within the provided time limit, submit his/her application or other document by mechanical means, if such means leaves an imprint that renders the identification of the forwarding and receipt machine as well as the date and time of forwarding and receipt unquestionable. However, the interested party should submit, in accordance with the provisions of articles 3 and 11, within five (5) days after the expiry of the time limit, a document with his/her signature, having the same content as the document received by the service by the mechanical means. The interested party may submit his/her document by registered mail if allowed by the relevant special provisions. In such cases, the date of submission is the date of delivery of the letter to the mail service. If the provisions require the joint submission of certificates, supporting documents or other public documents and if such documents are not jointly submitted for reasons that concern the administrative authority that is competent for their issuance, the timely submission of the document of the interested party is sufficient In such case, the document submitted by the interested party should state the reason for the non Joint submission of the public documents which, in any case, should be submitted by the interested party when the reason that made their joint submission impossible ceases to exist. The time limits for Administration are indicative, unless the provisions that determine them state that they are exclusive. The time limits for the issuance of individual administrative deeds, unfavourable for the person immediately concerned, are exclusive. The excess of the time limits is excused in cases of force majeure. For the calculation of the time limits, if not otherwise stipulated by special provisions, the provisions of articles 241-246 of the Civil Code are applied. 2. 3. 4. 5. 6. 7.
