Key legal question
Whether the EBK could grant international administrative assistance to the Greek market regulator despite objections based on confidentiality, speciality, and the long-hand principle.
Extracted holding
Yes. The HCMC was the competent foreign supervisory authority, gave sufficiently clear assurances of exclusive supervisory use, secrecy, and no onward transmission without Swiss consent; the appellants showed no concrete reason to distrust compliance.
Extracted reasoning
Art. 38(2) BEHG requires supervisory use, secrecy, and no onward transmission absent Swiss consent. The court held that a written assurance from the competent foreign authority is enough; a treaty-level guarantee is not required. Possible national reporting duties in Greece did not preclude assistance.
