Ministry of Defence: Joint Personnel Administration System
Lord Garden asked Her Majesty's Government:
What arrangements they have made for compensating members of the Royal Air Force who have not received correct payments on time since the introduction of the joint personnel administration system. [HL6437]
The Parliamentary Under-Secretary of State, Ministry of Defence (Lord Drayson): Any claims for compensation as a result of incorrect payments following the introduction of the JPA system will be considered in accordance with government accounting procedures. The general principle adopted is that the individual may be recompensed where it can be shown that a financial loss has occurred through maladministration.
