144.Section 33 provides that a contract which is entered into by the NDA is not invalidated by conduct of the NDA which is outside its powers or contravenes the duties imposed on the NDA by section 7(6) or 9 or a direction given by the Secretary of State under the Act. The section also stipulates that contractors are not required to enquire or see whether the transaction being entered into constitutes or involves such conduct or contraventions. Potential contractors will not therefore have to concern themselves with checking whether the Act has been complied with by the NDA before entering into a contract.
