Holding

The Constitutional Court held that the petition properly raised questions of constitutional interpretation. It found that the Supreme Court, by declining to apply its Rwabugande interpretation of Article 23(8) to the Petitioner's appeal while applying it to the materially comparable Wamutabanewe appeal, accorded unequal treatment in violation of Articles 21(1), 28(1), 44(c), 126(1) and 2(1). The Court ruled that a new constitutional rule in criminal procedure applies quasi-retroactively only to cases pending final determination, not to finally concluded cases. It therefore declined to set aside the sentence or order re-sentencing, but awarded the Petitioner 70% of his costs.

Outcome

Petition allowed in part; declarations granted, but the Petitioner's sentence was not set aside and re-sentencing was declined; 70% costs awarded to the Petitioner.

Facts

The Petitioner, a Kenyan national, was convicted of murder and sentenced by the High Court to 45 years' imprisonment. The Court of Appeal upheld the sentence on 25 August 2015 and the Supreme Court upheld it on 21 December 2018. On 3 March 2017 the Supreme Court in Rwabugande v Uganda held that Article 23(8) requires the period spent on remand to be arithmetically deducted from a sentence, departing from earlier authority. In the Petitioner's appeal the Supreme Court restated Rwabugande but declined to apply it, reasoning that the Court of Appeal had ruled before Rwabugande was decided. In the comparable Wamutabanewe appeal, however, the Supreme Court had deducted an extra year of remand time, reducing that sentence. The Petitioner contended that this differential treatment was discriminatory and unfair, and challenged the constitutionality of his sentence and of the selective, non-retroactive application of the Rwabugande interpretation of Article 23(8).

Issues

  1. Whether the petition raises any question or issue as to the interpretation of the Constitution.
  2. Whether the allegedly selective application by the courts of the interpretation of Article 23(8) of the Constitution as pronounced in Rwabugande v Uganda is fundamentally unfair and discriminative, and thus inconsistent with and in contravention of Articles 1, 2, 20, 21, 28(1), 44(c), 50, 126(1) and 127 of the Constitution.
  3. What remedies are available to the parties.

Orders

  • The petition is allowed in part.
  • Declaration that the Supreme Court's omission to determine the Petitioner's criminal appeal (Duke Mabeya Gwaka v Uganda, Criminal Appeal No. 59 of 2015) consistently with its determination of Wamutabanewe Jamiru v Uganda [2018] UGSC 8 constitutes a violation of Articles 2(1), 21(1), 28(1), 44(c) and 126(1) of the Constitution.
  • Declaration that a new constitutional rule in the realm of criminal procedure applies only quasi-retroactively to criminal cases and appeals pending final determination, and does not apply retroactively to cases that have been finally concluded.
  • 70% of the costs are awarded to the Petitioner.

Rules and key headnotes

Constitutional Law — Jurisdiction — Article 137 — Distinction between Constitutional Interpretation and Enforcement of Rights
The Constitutional Court's interpretative jurisdiction under Article 137 is engaged only where the determination of the question before it depends on the interpretation or construction of a provision of the Constitution; a claim that merely seeks redress for an infringed right, without calling for interpretation, must be pursued under Article 50 before another competent court.
Constitutional Law — Stare Decisis — Article 132(4) — Departure from Previous Supreme Court Decisions
Under Article 132(4) the Supreme Court may depart from its own previous decisions only where the previous decision is distinguishable, was overruled by a higher court, or was reached per incuriam; where a controversial departure is contemplated the apex court should sit en banc rather than allow one panel to overturn a precedent set by another.
Constitutional Law — Retroactivity of New Constitutional Rules — Quasi-Retroactivity in Criminal Procedure
A new constitutional rule in the realm of criminal procedure applies quasi-retroactively, that is, equally to all criminal cases and appeals pending final determination at the time the rule is enunciated, but does not apply with true retroactivity to cases that have already been finally concluded.
Human Rights — Equality and Fair Hearing — Articles 21(1) and 28(1) — Differential Treatment of Comparable Cases
Differential treatment of two cases by the courts is constitutionally justified only where the cases differ in some material respect; according unequal treatment to materially comparable appeals violates the right to equality before and under the law, equal protection of the law, and the non-derogable right to a fair hearing under Articles 21(1) and 28(1).
Criminal Law & Procedure — Sentencing — Article 23(8) — Taking Remand Period into Account
Article 23(8) requires a sentencing court to take into account the period a convict spent in lawful custody before completion of trial; following Rwabugande v Uganda this is to be done by arithmetic deduction of the remand period from the sentence, that decision now representing the applicable law on sentencing under Article 23(8).
Constitutional Law — Costs — Public Interest Litigation
A litigant who advances important constitutional questions of public interest should not ordinarily be condemned in costs even where unsuccessful; where such a litigant achieves partial success, the court may, applying the rule that costs follow the event, award partial costs in indemnification of expenses incurred.
