Under the WIDP Contract (Clause 37.5), the Contractor must ensure that all Personnel involved in providing the Service are required to disclose Convictions and that where any are in fact disclosed, the Authority must be informed without delay. The Authority can ask for copies of any unspent Convictions and require the removal of the relevant Personnel if the Authority considers their Convictions make them unsuitable for involvement in the Services (see Section 5.10.7 below on Unsuitable Persons).
The Contract Manager should check the terms of the Authority's Contract, which may have been further developed on a project specific basis depending on the services / facilities to be provided and the people involved.
