Key legal question
Whether the Federal Supreme Court could enter into the state-law appeal against the arbitral jurisdiction decision
Extracted holding
The Court could not enter because the case was a domestic arbitration matter, not an international one within Art. 176 IPRG.
Extracted reasoning
Under Art. 176(1) IPRG, the decisive factor is whether at least one party to the arbitration agreement had its domicile or seat abroad at the time of conclusion. Only the procedural parties matter; foreign non-party signatories do not internationalize the arbitration.
