Misc. Civil Cause No. 33 of 2020, High Court of Tanzania at Dar es Salaam
The petition arose from the retirement of the then Chief Justice of Tanzania, Hon. Prof. Ibrahim Hamis Juma, who attained the age of 65 years on 15 June 2023.
Humphrey Simon Malenga petitioned the High Court challenging the continued tenure of the Chief Justice. His argument was essentially that Article 118(2) of the Constitution required the Chief Justice to leave office upon reaching the retirement age applicable to a Justice of Appeal, which he understood to be 65 years, and that the presidential powers under Article 120(2) and (3) to suspend retirement or extend the tenure of a Justice of Appeal did not apply to a Chief Justice.
The Attorney General opposed the petition, arguing that Articles 118 and 120 had to be read together. Since the Chief Justice is appointed from among persons qualified to be Justices of Appeal, the retirement provisions and exceptions in Article 120 also applied to the Chief Justice.
The principal issues before the Court were:
Whether Article 118(2) provides an independent retirement age for the Chief Justice or refers to the retirement framework applicable to a Justice of Appeal.
Whether Article 118(2) is a stand-alone constitutional provision, such that Articles 120(2), (3) and (4) cannot be relied upon when determining the tenure of the Chief Justice.
Whether the President's constitutional powers to suspend the retirement age or extend the tenure of a Justice of Appeal under Article 120(2) and (3) apply where that Justice of Appeal is also the Chief Justice.
Whether the extension/suspension of the Chief Justice's tenure was constitutional.
The High Court dismissed the petition for want of merit.
The Court held that the Chief Justice is, constitutionally, also a Justice of Appeal. Therefore, Article 118(2) cannot be interpreted in isolation from Article 120.
The Court adopted a harmonious and purposive approach to constitutional interpretation, holding that the Constitution must be read as an integrated whole so that its provisions sustain rather than contradict one another.
Consequently, the presidential powers contained in Article 120(2) and (3) could apply to a Chief Justice who is also a Justice of Appeal. The Court therefore found no constitutional basis for declaring the extension of the Chief Justice's tenure unlawful.
The petition was accordingly dismissed, with no order as to costs.
The case is important for constitutional interpretation and separation of powers in Tanzania.
First, the Constitution must be read as a whole. The Court rejected an interpretation that treated Article 118(2) as an isolated provision. It applied the established principle that constitutional provisions should be interpreted harmoniously and purposively.
Second, the case clarifies the constitutional status of the Chief Justice. The Court's reasoning establishes that, for purposes of the relevant retirement provisions, the Chief Justice is also a Justice of Appeal. This was central to the application of Article 120.
Third, it recognizes the scope of presidential constitutional powers. Where the Constitution gives the President power to suspend retirement or extend the tenure of a Justice of Appeal, those powers are not automatically excluded merely because the Justice concerned also occupies the office of Chief Justice.
Fourth, the decision reinforces the judiciary's constitutional role in interpretation. The Court emphasized that while Parliament legislates and the Executive implements government functions, the Judiciary has the responsibility of interpreting the law and Constitution.
Fifth, the case illustrates the importance of purposive constitutional interpretation. The Court relied, among others, on the reasoning in Julius Francis Ishengoma Ndyanabo v Attorney General [2004] TLR 14, as well as the Mtikila authorities, emphasizing that the Constitution should not be interpreted narrowly or technically in a manner that defeats its broader constitutional purposes.
The lasting principle from Malenga v Attorney General is that a constitutional provision concerning an office cannot necessarily be interpreted in isolation where another constitutional provision supplies the substantive mechanism governing that office. Articles 118 and 120 must therefore be read together.
In practical terms, the case is a useful authority for the proposition that constitutional interpretation requires harmony, context, purpose and the Constitution as a whole, rather than mechanically applying one Article while disregarding related provisions.
