Knowledge Check
Joint ventures, contractual parties and adjudicator jurisdiction

This Knowledge Check examines Darchem Engineering Limited's application to enforce an adjudicator's award of GBP 23,944,012. The subcontract connected two unincorporated joint ventures involved in stainless-steel works for Hinkley Point C.

Darchem commenced adjudication alone, although the subcontractor joint venture, EDEL, comprised Darchem and Framatome. The main-contractor joint venture, BYLOR, challenged jurisdiction because Darchem was not itself the defined subcontracting Party.

The court construed the agreement, conditions and subcontract data as a whole. It held that the contract was bilateral between the two joint ventures, joint and several liability did not make each member a separate Party, and Darchem could not invoke the adjudication clause in its own right.

This Knowledge Check covers
  • The two unincorporated joint ventures
  • The three adjudications commenced by Darchem
  • The defined Contractor, Subcontractor and Parties
  • The dispute-resolution provisions in Option W
  • The bilateral drafting of the subcontract conditions
  • The joint and several liability provision
  • The notified-leader machinery in clause 12.6
  • The order-of-precedence argument
  • The risk of parallel adjudications
  • The refusal of summary enforcement
