In the course of the proceedings, the parties shall be free to raise new grounds in support of their
claims.
They may also file fresh claims, whether counter claims or not if the said claims are within the
limits of the arbitration agreement, and unless the arbitrator considers that he does not have to
authorise such an extension of his mission, due in particular, to the delay in filing the claim.
