Key legal question
Whether the award was tainted by impermissible prior involvement because the head of the drafting committee worked for the successful bidder.
Extracted holding
The appearance of unequal treatment was sufficient to undermine fair competition; participation in drafting the tender documents by an employee of the winning firm was incompatible with equal treatment.
Extracted reasoning
A bidder who helped prepare the project or tender documents gains a knowledge advantage and creates at least the appearance that not all bidders were on equal terms; actual advantage need not be proven.
