Question juridique clé
Whether the EBK properly granted mutual assistance to BaFin in the insider trading inquiry
Solution extraite
The appeal failed; the request met the threshold of an initial suspicion and the assistance was proportionate.
Motifs extraits
The court held that the merits of the insider-trading suspicion are for the foreign authority to assess. An initial suspicion suffices when transactions coincide with unusual price movements, and the appellant did not clearly refute that suspicion.
