Article 34
Annulment and revocation
A visa shall be annulled where it becomes evident that the conditions for issuing it were not met at the time when it was issued, in particular if there are serious grounds for believing that the visa was fraudulently obtained. A visa shall in principle be annulled by the competent authorities of the Member State which issued it. A visa may be annulled by the competent authorities of another Member State, in which case the authorities of the Member State that issued the visa shall be informed of such annulment. A visa shall be revoked where it becomes evident that the conditions for issuing it are no longer met. A visa shall in principle be revoked by the competent authorities of the Member State which issued it. A visa may be revoked by the competent authorities of another Member State, in which case the authorities of the Member State that issued the visa shall be informed of such revocation. A visa may be revoked at the request of the visa holder. The competent authorities of the Member States that issued the visa shall be informed of such revocation. Failure of the visa holder to produce, at the border, one or more of the supporting documents referred to in Article 14(3), shall not automatically lead to a decision to annul or revoke the visa. If a visa is annulled or revoked, a stamp stating ‘ANNULLED’ or ‘REVOKED’ shall be affixed to it and the optically variable feature of the visa sticker, the security feature ‘latent image effect’ as well as the term ‘visa’ shall be invalidated by being crossed out. A decision on annulment or revocation of a visa and the reasons on which it is based shall be notified to the applicant by means of the standard form set out in Annex VI. A visa holder whose visa has been annulled or revoked shall have the right to appeal, unless the visa was revoked at his request in accordance with paragraph 3. Appeals shall be conducted against the Member State that has taken the decision on the annulment or revocation and in accordance with the national law of that Member State. Member States shall provide applicants with information regarding the procedure to be followed in the event of an appeal, as specified in Annex VI. Information on an annulled or a revoked visa shall be entered into the VIS in accordance with Article 13 of the VIS Regulation.
Eftersom du inte har informerats om viseringens återkallande och viseringen inte har stämplats eller korsats, kan du dra slutsatsen att viseringen är giltig.
