Questão jurídica principal
Whether the administrative appeal against the incidental decision was admissible
Decisão extraída
Yes, because the decision could cause irreparable prejudice by allowing disclosure of confidential submissions, and the final decision on the takeover obligation would itself be appealable.
Fundamentação extraída
The order was incidental, but it was immediately challengeable since the appellant had a protectable interest in preventing transmission of confidential filings to the Edelman group; a later favorable decision would not fully cure the harm.
