Under section 340A(1) and (2) of the Armed Forces Act 2006 (c. 52) (“the Act”), a person subject to service law, or who has ceased to be subject to service law, who thinks they have been wronged in any matter relating to their service, may make a service complaint about the matter. Under section 340H(1) of the Act the complainant may apply to the Service Complaints Ombudsman to investigate their complaint or related maladministration. The Armed Forces Act 2021 (c. 35) amended the date from which the minimum period to apply to the Service Complaints Ombudsman for an investigation under section 340H(1)(a) or (b) of the Act is calculated.
