14According to ZUBERBÜHLER, group of companies doctrine is often used as an umbrella term for all the non-signatory scenarios where the fact of a corporate relationship among signatory and non-signatory parties plays an important role. He further adds that decisions show that the finding of an (implied) consensus remains key in binding non-signatories to an arbitration clause (ZUBERBÜHLER, Non-Signatories and the Consensus to Arbitrate, in ASA Bulletin, 2008, Vol. 26, p. 25).

17PCA Case No. 2011-09, Decision on Jurisdiction, 25.07.2012, Arbitrator Intelligence Materials, para. 331: “The Respondents insist that Mongolian law does not recognize the socalled ‘group of companies doctrine’. In this respect, the Tribunal observes that the Claimants do not rely on this doctrine. The Tribunal further notes that no clear submissions have been made as to the content of any such doctrine. In the Tribunal’s view, the mere existence of a group of companies cannot affect the scope of the arbitration clause. As stated above, the relevant inquiry is into the common intention of the Parties, as manifested through their conduct in the negotiation, performance, and termination of the contract”.
