The parties entered into a JCT With Contractor鈥檚 Design contract for the construction of 114 residential apartments in Manchester. This case concerns the enforcement of an adjudicator鈥檚 decision. During the adjudication, Crosby Homes raised three jurisdictional challenges:

1 There was no jurisdiction under the 鈥渟ide agreements鈥

2 If there was an agreement it was not in writing

3 If there was a written agreement then it was not a construction contract.

Two main issues arose at trial. First, under the main contract, does the adjudicator have jurisdiction in respect of disputes arising 鈥渦nder the contract鈥, or does his jurisdiction extend to disputes 鈥渦nder, out of or in connection with the contract鈥. Second, were the disputes referred to the adjudicator arising 鈥渦nder鈥 and/or 鈥渙ut of or in connection with鈥 the contract?
