According to the court, the "default" position on costs is that the CMA should not be liable for other parties' costs when it brings or defends proceedings acting purely in its regulatory capacity. The court decided there was a public interest in encouraging public bodies to exercise their public function of making reasonable and sound decisions without fear of exposure to undue financial prejudice even when such decisions are successfully overturned.
That "default" position "may be departed from for good reason; but the mere fact that the regulator has been unsuccessful is not enough", the court said. A good reason will include unreasonable conduct on the part of the regulator, or substantial financial hardship likely to be suffered by the successful party if a costs order is not made. There may be additional factors, specific to a particular case, which might also permit a departure from the starting point, the court said.
"Apportioning costs for an appeal of a CMA decision on this basis is problematic as it indicates the CMA is in a position of 'tails I win, heads I win'," Vidal said. "If the CMA wins an appeal it can claim very significant costs from the losing appellant. For example, Ping Europe was recently forced to pay over £800,000 of the CMA’s costs following its unsuccessful appeal to the CAT. It appears Ping will have had to pay well over £2 million in legal costs when the total fine issued by the CMA in the case was £1.25 million. This judgment by the Court of Appeal would mean that even where the CMA loses an appeal it would be immune, as parties would find it very difficult to claim back the costs incurred defending themselves from what are quasi-criminal penalties. It will be interesting to see if this judgment is now appealed to the Supreme Court."
"It is difficult to understand why the Court of Appeal felt the state, with its significant enforcement powers and much deeper pockets, needed to be further advantaged in this way. If the judgment is allowed to stand it will undoubtedly exert a significant chilling effect on companies that are considering an appeal of a poor CMA decision. The fact the CMA is currently seeking to increase its legal powers and further narrow the scope of future appeals does not bode well," he said.
