[2007] UKSSCSC CAF_857_2006 (02 April 2007)

Factual and Procedural Background

This case concerns an appeal by a former service member ("Appellant") against a tribunal decision dismissing his appeal under section 5A(1) of the Pensions Appeal Tribunals Act 1943. The tribunal had upheld a review decision made by the Secretary of State on 5 July 2004, which specified 1 February 1976 as the commencement date of a pension award for a condition described as "depressive episode". The Appellant contended that the award should have commenced on the date his service ended, 2 February 1965.

The Appellant joined the Royal Air Force on 24 February 1959 and served until his medical discharge on 1 February 1965 due to a condition diagnosed as "simple schizophrenia". This diagnosis followed treatment for mental health issues during and after service in Kenya under stressful conditions. Despite his discharge and deemed pension claim for "psychosis" in 1965, the claim was rejected.

In 2004, the Appellant submitted a claim described as "mental injury caused by unreasonable unfair conditions of service" and "memory and reaction injury caused by the treatment I received". This was treated as a review of the 1965 decision, resulting in acceptance of a "depressive episode" attributable to service, with disablement assessed from 1 February 1976.

The procedural history includes an oral hearing on 7 September 2006, and the appeal was heard by a Commissioner who ultimately found the tribunal's decision legally erroneous and referred the case for re-determination by a differently constituted tribunal.

Legal Issues Presented

1. Whether the tribunal erred in law by failing to provide adequate reasons for choosing 1 February 1976 as the commencement date of the pension award.
2. Whether the Secretary of State's review decision was correctly based on a change in medical opinion justifying backdating of the award.
3. Whether the original 1965 refusal of pension entitlement resulted from official error, permitting backdating of the award to the date of medical discharge.
4. The proper application of Schedule 3 to the 1983 Service Pensions Order in determining the commencement date of the award.

Arguments of the Parties

Appellant's Arguments

• The pension award should commence on 2 February 1965, the date of medical discharge, not 1 February 1976.
• The original refusal of pension was based on a misdiagnosis and failure to consider the impact of service conditions.
• The delay in claiming was due to a mistaken belief that no basis existed to challenge the refusal.

Secretary of State's Arguments

• The commencement date of 1 February 1976 was justified by a change in medical opinion, consistent with established policy and legal precedent.
• The tribunal's dismissal of the appeal was appropriate given the evidence and prevailing medical understanding at the time.
• The backdating of awards is limited by statutory provisions, including a three-year maximum period before the review application.
• The original refusal did not constitute official error under the relevant legal standards.

Precedent	Rule or Principle Cited For	Application by the Court
R v. Secretary of State for Social Security ex parte Edwards (1992)	Clarification of the date from which pension awards could be backdated based on reliable medical evidence rather than medical consensus.	Used to justify the Secretary of State's discretion in selecting 1 February 1976 as the commencement date linked to evolving medical opinion.
R v. Secretary of State for Social Security ex parte Foe (1995)	Lawfulness of backdating awards by up to five years when original refusal was reasonable on the information then available.	Referenced to explain the discretionary framework prior to codification in Schedule 3 of the 1983 Service Pensions Order.
R(SB) 2/93	Definition of "clear and obvious mistake" for official error in social security adjudication.	Applied to interpret the concept of official error under Schedule 3 paragraph 1(6A) concerning erroneous medical advice.
R(H) 2/04	Application of the "clear and obvious mistake" test in housing benefit regulation cases.	Reinforced the approach to official error, supporting consistency in interpreting similar statutory language.

Court's Reasoning and Analysis

The Court found the tribunal's reasons for selecting 1 February 1976 as the commencement date manifestly inadequate, primarily because the tribunal did not explain the development of medical opinion or provide relevant scientific material. This deficiency warranted setting aside the tribunal's decision.

The Court analysed the legal framework governing pension awards, focusing on Schedule 3 to the 1983 Service Pensions Order and the Secretary of State’s review powers under regulation 67. It distinguished between reviews based on changes in medical opinion and those based on official error, noting that the latter requires a "clear and obvious mistake" assessed against medical knowledge at the time of the original decision.

The Court expressed doubt that the change in medical opinion related to schizophrenia was relevant to the Appellant’s accepted condition of depressive episode. It emphasized that misdiagnosis alone does not establish official error; rather, the original decision must be shown to have been clearly mistaken in light of contemporary medical standards.

Given the complexity of the medical issues and the inadequacy of the tribunal's reasons, the Court declined to substitute its own decision and instead referred the case for rehearing before a differently constituted tribunal. The new tribunal was instructed to consider the original diagnosis, contemporaneous medical records, the Appellant's evidence of service conditions, and relevant medical knowledge as of 1965.

The Court also noted that any increase in the Appellant's disablement assessment could affect the practical benefit of the appeal and recommended that the Secretary of State review the assessment if the appeal succeeded.

Holding and Implications

The Court's final decision was to SET ASIDE the tribunal's decision and to refer the case for re-determination by a differently constituted tribunal under section 6A(4) of the Pensions Appeal Tribunals Act 1943.

The direct effect is that the Appellant’s case will be reconsidered with a proper and detailed examination of the medical and factual issues relevant to the commencement date of the pension award. No new legal precedent was established by this decision; rather, it reaffirmed the necessity for tribunals to provide adequate reasons and to properly apply statutory provisions governing pension awards and official error.
