From the presentations at the review it was clear that no technical showstoppers had so far been identified, although some aspects of the mission remained inadequately defined for a definite conclusion to be possible. However, it was also the impression that the mass and, to some extent, power requirements left too little margin for the further development. Also, it was felt that the complexity and likely cost might exceed what was realistic within the limits of a small satellite programme. Further discussion, and recommendations from the international panel taking part in the review, formed the basis for the final decision, taken by Eigil Friis-Christensen, the director of the Danish Space Research Institute. This link contains a note, in pdf form written by Eigil Friis-Christensen to discuss the considerations leading to the final decision.
