¹ Ar­bit­ra­tion may be ini­ti­ated by or against joint parties if:

a.

all the parties are con­nec­ted among them­selves by one or more cor­res­pond­ing ar­bit­ra­tion agree­ments; and

b.

the as­ser­ted claims are identic­al or fac­tu­ally con­nec­ted.

² Fac­tu­ally con­nec­ted claims between the same parties may be joined in the same ar­bit­ra­tion pro­ceed­ings if they are the sub­ject of cor­res­pond­ing ar­bit­ra­tion agree­ments between these parties.

³ The in­ter­ven­tion of a third party and the join­der of a per­son no­ti­fied as a party to an ac­tion re­quire an ar­bit­ra­tion agree­ment between the third party and the parties to the dis­pute and are sub­ject to the con­sent of the ar­bit­ral tribunal.
