Answer ... No specific provision allows or prohibits the tribunal from consolidating separate arbitration proceedings. Therefore, the general principles of the Greek Code of Civil Procedure apply, according to which consolidation is feasible if the disputes at stake have similar legal and factual elements, and a high correlation exists between the different claims pursued through the separately initiated arbitration proceedings.

Answer ... In the absence of a relevant provision under Greek law imposing such a restriction, third parties may participate in the arbitration by submitting a joinder or a third-party notice, provided that the parties to the dispute and the tribunal have expressed their consent.

Answer ... The tribunal cannot assume jurisdiction over parties that are not bound by the arbitration agreement, unless they have joined the arbitration proceedings or are legally linked to the contracting parties (eg, successor or assignee).
