Key legal question
Whether the appeal had to be dismissed as inadmissible for failure to pay the advance on costs.
Extracted holding
Yes. The appellant did not pay the advance within the final deadline, so the appeal was inadmissible under Art. 62 LTF.
Extracted reasoning
Art. 62 LTF requires the appellant to pay an advance on costs; if the second deadline expires without payment, the appeal must be declared inadmissible. The appellant's reliance on voting-rights character, Article 13 ECHR, and Article 29a FC did not justify an exemption or relieve him from payment.
