Can a panel refer to the European Court of Justice in an ADR .eu procedure?

On the ADR decisions.eu Wiki, Thomas Schafft mentions a German language case over flights.eu.
For the first time (and amazingly), the Panel issues an interim injunction in which it refers to the ECJ... first to ask if the Arbitration Center for .eu Disputes is allowed to do so, and two other questions.
A case worth watching!
