Question juridique clé
Whether the appeal had to be admitted despite the unpaid court advance and the appellant's ambiguous letter.
Solution extraite
No. The letter of 2 July 2010 was not a clear and unequivocal withdrawal, and the cost advance remained unpaid even after the grace period.
Motifs extraits
Because the advance was not paid within the extended deadline, Article 62(3) BGG required non-entry in simplified proceedings under Article 108(1)(a) BGG.
