Questão jurídica principal
Whether the precautionary account freeze was lawful as a confiscation measure.
Decisão extraída
The freeze was lawful because a concrete suspicion and a sufficient connection to potentially tainted assets existed, and confiscation or substitute-claim security could still be considered.
Fundamentação extraída
The court held that precautionary confiscation only requires a sufficiently substantiated concrete suspicion and compliance with proportionality. The disputed account contained unexplained inflows and transfers, so the authorities could not exclude illicit proceeds or substitute-claim security. The freeze did not prejudge the merits.
