Key legal question
Whether the seizure of the appellants' bank relations was admissible and proportionate.
Extracted holding
The seizure was sufficiently grounded in suspicion, linked to the suspected offences, and proportionate; the challenge failed.
Extracted reasoning
Early-stage criminal proceedings require only plausible suspicion. The Grisons investigative order and the file showed enough links between the company liquidation, B., and A. to justify examining the appellants' accounts over a longer period.
