The scope of the service is based on realistic calculations. There is, however, a certain uncertainty regarding the scope within the sub-contracts that the Norwegian Patient Injury Compensation (NPE) will need. NPE reserves the right therefore to change the estimated number of hours and the number of contracts within the sub-contracts if the need changes in the contest phase. If the need for a sub-contract ceases, for example, due to a significant decline in the number of cases, NPE reserves the right to cancel the contest for the sub-contract.
