Key legal question
Whether the interlocutory decision was appealable under Art. 92 BGG as a decision on jurisdiction or recusal
Extracted holding
No. The appellant did not challenge the federal court's competence, but the committee's competence, which was itself still pending below; no recusal decision was shown either.
Extracted reasoning
A decision is appealable under Art. 92 BGG only if it concerns the deciding court's jurisdiction or a recusal motion. The committee's jurisdiction remained the subject of the pending case before the arbitration court.
