[16] Finally, the applicant suggested, summary disposition of the application would in any event be inappropriate until disclosure had been given and all material constituting the whole road infrastructure program had been put in evidence. It was possible, it was said, that "documents will be turned up, which will identify, maybe, a different source by which the decisions were made". But the content of the Standard Specifications Manual, on which the applicant relies as encapsulating the relevant program, is known; it is not suggested that there is anything uncertain or yet to be ascertained in that regard. Although the Roads Implementation Program is not fully in evidence, it is a matter of construction whether it is a statutory or non-statutory program. If it is the former, and if the decision was made under it, the decision will not be amenable to review, whatever else might emerge about the program's compass. I do not think that resolution of the questions posed here can properly be deferred on the off chance that something else might turn up, particularly when there is no hint of anything further involved in the decision making process.
