How long have you got to challenge the adjudicator’s decision? The English Court of Appeal has decided: 1) the claimant who considers the adjudicator awarded too little must challenge before the original limitation period for his claim expires; and 2) the defendant who considers he paid too much has a new limitation period starting on the day he paid the adjudicator’s decision. Is it unfair that the loser may have years longer than the winner? That question will soon be answered by the Supreme Court of the United Kingdom. Their decision will be of interest to anyone involved with FIDIC DABs anywhere in the world.
