The power to determine compliance with the essential requirements of an Adjudication Application could lie with the authorised nominating authority (to whom the application is made), the adjudicator (to whom the application is referred) or the Court exercising its supervisory jurisdiction.
The structure of the Act might suggest that it would be inappropriate to refer an invalid Adjudication Application to an adjudicator; there would then be an implied obligation on the authorised nominating authority to consider the validity of the application made to it. Arguably the duty to refer an application to an adjudicator (see s 17(6)) is limited to a valid Adjudication Application. However, as no party before this Court argued for that construction, it may be put to one side.
The second possibility is that power to determine the validity of an Adjudication Application lies with the adjudicator. In a practical sense, there is much to recommend the view that the adjudicator is able to determine whether the application complies with provisions such as s 17(2)(a), as the adjudicator sought to do in the present case. However, there are factors which support a contrary view. First, s 22(1), identifying that which the adjudicator is to determine, makes no reference to the validity of the Adjudication Application. Secondly, s 22(2), limits the matters which the adjudicator is entitled to consider to the Act, the provisions of the construction contract, the payment claim, the payment schedule, submissions in support of either and the results of any inspection. In a provision which renders the consideration of any other material impermissible, the absence of any reference to the circumstances in which the Adjudication Application was made is highly significant.
Thirdly, the descriptions of the matters to which payment claims and payment schedules must relate and hence (at least implicitly) the matters to which the submissions in support can properly refer, do not expressly identify any aspect of the circumstances in which the Adjudication Application was made.
For these reasons, the proper construction of the Security of Payment Act is that it does not permit the adjudicator to determine the validity of the Adjudication Application. The challenge in the present case must therefore be determined on the basis of facts found by the Court. [63]
