Kernrechtsfrage
Whether the Federal Supreme Court could revisit the advance-cost question decided in a prior final judgment.
Extrahierter Entscheid
The issue could no longer be reopened because it had already been finally decided in judgment 1B_132/2010.
Extrahierte Begründung
The appellant merely challenged the advance costs again; the matter was already res judicata at federal level, so no further review was possible.
