Questão jurídica principal
Whether the civil-law complaint remained admissible after the advance payment was made.
Decisão extraída
No current and practical interest remained, so the complaint could not be heard.
Fundamentação extraída
Appeal standing under Art. 76 BGG requires a current practical interest at the time of the Federal Supreme Court judgment. That interest disappeared once the advance was paid, because the challenged rulings only conditioned continuation of the appeal on that payment.
