R v Secretary of State for the Home Department, Ex parte Pierson (John David)

Maintaining the same penal tariff after abandoning material aggravating assumptions may amount in substance to an increase in punishment. The general statutory discretion to release mandatory life prisoners did not authorise the Home Secretary, in these circumstances, to increase a tariff already fixed and communicated merely because the appropriate punishment had been reconsidered.

General statutory powers are construed against fundamental common-law principles unless Parliament uses clear language. The majority nevertheless reached its conclusion by different routes: the applicable policy precluded an increase; the principle of legality constrained retrospective aggravation; and substantive fairness governed a decision concerned solely with punishment. Whether exceptional circumstances could justify an increase was left open.

R v Secretary of State for the Home Department, Ex parte Pierson (John David) concerned the penal element of a mandatory life sentence for two murders. The judiciary recommended 15 years, but the Home Secretary initially fixed 20 years on assumptions including premeditation and the aggravating effect of two separate offences.

That decision was quashed in earlier proceedings reported as Regina v Secretary of State for the Home Department, Ex parte Doody [1994] 1 AC 531. On reconsideration, the Home Secretary accepted that the murders were unpremeditated and formed one short incident, but again fixed 20 years. Turner J quashed that decision. The Court of Appeal allowed the Home Secretary’s appeal: [1996] 3 WLR 547.

The central issue was whether the statutory release discretion or the 1993 policy permitted what was substantively an increase in the previously fixed tariff.

1. Disposition. The House allowed the appeal by a majority of three to two and quashed the Home Secretary’s decision to re-fix the penal element at 20 years. All five Law Lords accepted that retaining 20 years after removing the material aggravating assumptions amounted in substance to an increase.
2. Lord Goff of Chieveley. The policies applicable when the tariff was originally fixed stated that it would not be increased, apart from a specified circumstance which did not apply. The 1993 policy referred naturally to an initial view taken at the beginning of a sentence. It did not retrospectively alter tariffs fixed under the earlier policy. The Home Secretary therefore misconstrued the policy and should have reduced the tariff after accepting that its original factual basis was mistaken.
3. Lord Steyn. Fixing the punitive tariff was closely analogous in substance to sentencing. Under the principle of legality, the general language of section 35(2) of the Criminal Justice Act 1991 was presumed to operate consistently with the fundamental principle against retrospectively increasing a lawfully fixed punishment. Parliament had not conferred a general power to increase a fixed and communicated tariff. The unlawful reservation of such a power in the 1993 policy was severable from the otherwise lawful tariff policy.
4. Lord Hope of Craighead. The Home Secretary retained broad flexibility over release and could change policy. A narrower rule applied, however, when his decision was concerned purely with punishment rather than wider policy. Substantive fairness then required observance of the constraints governing judicial punishment. A communicated minimum period could not be increased merely because the Home Secretary later considered it inadequate. Lord Hope and Lord Steyn left open whether exceptional circumstances, such as material deception, might justify an increase.
5. Dissent. Lord Browne-Wilkinson and Lord Lloyd of Berwick would have dismissed the appeal. They considered that no universal common-law rule prohibited an increased punishment and that a mandatory-life tariff was not a judicial sentence. In their view, the broad statutory discretion permitted the 1993 policy, subject to rationality and procedural fairness.

1. House of Lords: By a majority of three to two, allowed the prisoner’s appeal and quashed the Home Secretary’s decision: R v Secretary of State for the Home Department, Ex parte Pierson (John David) [1998] AC 539.
2. Court of Appeal: Allowed the Home Secretary’s appeal from Turner J and held that the statutory discretion permitted an upward revision of the penal term: [1996] 3 WLR 547.
3. High Court: Turner J allowed the application for judicial review and quashed the decision maintaining the penal element at 20 years.
