While the estimated liability was increasing, the Department stuck with the figure of €127 million. Even when its calculations were showing liability could exceed €0.5 billion, it did not revise this figure. The Comptroller and Auditor General has stated that as additional information comes to hand it would be reasonable to expect that the full range of potential costs would be revised. This has not been done. In fact, no revision of the lower estimate of the potential cost was made despite evidence that the number of claimants was rising rapidly.
