ALHAJI BASHIR ZUBAIRU USMAN V. KADUNA STATE HOUSE OF ASSEMBLY & ORS. (2007)

Background

Alhaji Bashir Zubairu Usman was a member of the Kaduna State House of Assembly representing Sabon Gari Constituency. He had previously served as Speaker of the House, but after his removal from that office in December 2005, he continued as an ordinary member. On 9 August 2006, the then Speaker announced that his seat had become vacant, purportedly pursuant to section 109(1)(f), (2) and (3) of the 1999 Constitution. The stated basis was the belief that Usman had been absent from sittings for an aggregate period exceeding one-third of the total number of sitting days in the legislative year.

Usman challenged the action before the Kaduna State High Court. He sought declarations that his expulsion and the declaration of his seat as vacant were unconstitutional, null and void; that he remained a member of the House until lawfully removed; injunctions restraining further interference with his membership; and damages for the alleged violation of his constitutional rights. His central complaint was that the respondents had acted without giving him an opportunity to be heard and without producing evidence demonstrating the constitutionally required level of absence.

During the proceedings, the trial Judge initially ruled on 12 September 2006 that the High Court possessed jurisdiction, stating that the action concerned fundamental rights and fair hearing rather than an election dispute. The case proceeded to trial, and both sides called evidence. However, in the final judgment delivered on 31 October 2006, the same Judge reversed that position, held that the High Court lacked jurisdiction, and struck out the suit. Usman appealed.

Issues

1. Whether the trial Judge could reverse an earlier ruling in the same proceedings which had determined that the High Court had jurisdiction.
2. Whether the State High Court had jurisdiction over a claim challenging the constitutionality of the declaration of a legislative seat as vacant and alleging denial of fair hearing.
3. Whether the evidence established that the respondents had breached sections 36 and 109 of the 1999 Constitution.
4. Whether the appellant’s grounds of appeal were competent, particularly those alleged to be argumentative, vague or unrelated to the judgment.

Ratio Decidendi

The Court of Appeal held that a court which has delivered an effective ruling or judgment on an issue cannot reopen that issue and substitute a contrary decision merely because it later changes its mind. The proper method of challenging the earlier decision is through appellate jurisdiction. Once the trial court delivered its ruling on jurisdiction, it became functus officio in relation to that determination, subject only to limited powers to correct accidental slips, omissions or mathematical errors and to make ancillary orders. The subsequent “judgment” reversing the ruling was therefore incompetent.

The Court further held that jurisdiction is determined primarily by the plaintiff’s claim and the reliefs sought. Section 285 of the Constitution confers exclusive jurisdiction on election tribunals in specified electoral matters, including questions concerning whether a person was validly elected. The present action did not challenge an election or the validity of Usman’s election. It challenged an administrative and constitutional act of expulsion and the declaration of vacancy, together with an alleged denial of fair hearing. Those claims fell within the general civil jurisdiction of the State High Court under section 272 and included matters concerning constitutional rights and interpretation of section 109.

The Court also reaffirmed that fair hearing is fundamental. It requires that a person affected by a determination of civil rights or obligations be given a real opportunity to present his case before an impartial decision-maker. The respondents could not validly declare Usman’s seat vacant without first presenting satisfactory evidence to the House that the constitutional condition of absence exceeding one-third of the relevant sittings had been met.

Court Findings

The Court rejected the preliminary objection to grounds of appeal 1, 2 and 3. A ground is not incompetent merely because it alleges both error in law and misdirection in fact, provided it clearly informs the respondent of the complaint and complies with the rules. Particulars of error must identify the specific reasoning, finding or observation challenged, but they may, in appropriate circumstances, be incorporated within the ground itself. Ground 4, the omnibus complaint that the judgment was against the weight of evidence, was struck out because the trial court had not evaluated the evidence or determined the case on its merits.

On the merits, the appellate court examined the record under section 16 of the Court of Appeal Act. It noted that the trial Judge had failed to evaluate the evidence, making it permissible for the Court of Appeal to act in the place of the trial court because witness credibility and demeanour were not in issue. The appellant testified that he had not been absent for the required period and had not been invited to answer the allegation. The respondents’ own witness confirmed that the relevant documents did not identify the period of absence, that Usman had not been queried, and that the available figures did not establish absence exceeding one-third of the sittings. Because the respondents did not treat their witness as hostile, the evidence supporting the appellant’s case operated as an admission or further reinforcement of it.

Conclusion

The appeal was allowed. The High Court judgment of 31 October 2006 was set aside and declared null for want of competence. The Court of Appeal held that the Kaduna State High Court had jurisdiction to hear and determine the action. It entered judgment for Usman on the principal declarations: his purported expulsion and the declaration that his seat was vacant were unconstitutional, null and void, and he remained a member of the House until legally or constitutionally removed. The remaining injunctive and damages claims were refused and dismissed. Costs of N10,000 were awarded to the appellant in the Court of Appeal and N5,000 in the court below.

Significance

The decision is significant for Nigerian constitutional and appellate procedure. It confirms the limits of a trial court’s power to revisit its own concluded rulings and emphasises that a court cannot sit on appeal over itself. It also clarifies that legislative disputes do not automatically become election matters merely because they concern a seat in a legislative house. The substance of the reliefs, not the political context, determines jurisdiction. Finally, the case demonstrates that constitutional safeguards concerning fair hearing and proof of legislative disqualification must be respected before a member’s seat can be declared vacant.
