Article 10.6 (Suspension by arbitral proceedings)

The running of the limitation period is suspended when the obligee performs any act, by commencing arbitral proceedings or in arbitral proceedings already instituted, that is recognised by the law of the arbitral tribunal as asserting the obligee's right against the obligor. In the absence of regulations for arbitral proceedings or provisions determining the exact date of the commencement of arbitral proceedings, the proceedings are deemed to commence on the date on which a request that the right in dispute should be adjudicated reaches the obligor.

Suspension lasts until a binding decision has been issued or until the proceedings have been otherwise terminated.
