How long do you have to challenge an adjudicator’s decision? Controversially, the English Supreme Court has now ruled as follows: If you were the loser and required to pay monies, you will have the full limitation period, typically six years, to bring your claim to recover those monies starting from when you were required to make payment to the winner; whereas If you were the winner, your right to seek an improvement of the result will come to an end at the same time as the limitation period for the original claim.
