I would say that the most important finding was that for a variety of reasons, a number of decisions have been taken in recent years that fly in the face of the economic evidence to hand. One of those sets of issues—the most obvious set of issues of that kind—would be the frequent extension of the duration of copyright to a point where it is certainly not economically rational to take the actions that have been taken.
Of course, politicians have to take into account matters that are not economic. I would say that the general argument about if you want your IP system to do well for the economy and innovation you'd better make sure you gather the evidence and take the evidence fully into account in making political decisions is the single most important argument in the review, because it applies to all aspects of the review.
