Key legal question
Whether the appeal was admissible and whether the subsidiary request for a declaration of illegality was still open despite no contract having been signed.
Extracted holding
The public-law appeal was in principle admissible, but the subsidiary request for a declaration of illegality was inadmissible because no contract had been concluded.
Extracted reasoning
Without a contract, there was no need to limit review to damages under the market-internal-law rule; the declaratory request therefore lacked admissibility.
