Won Three Times, Sent Back to Square One: A Twenty-Year Inheritance Fight Undone by a Missing Signature: Katsayel v. Abdullahi [2026] 12 NWLR (Pt. 2053) 1 — Supreme Court of Nigeria


Won Three Times, Sent Back to Square One: A Twenty-Year Inheritance Fight Undone by a Missing Signature

Katsayel v. Abdullahi [2026] 12 NWLR (Pt. 2053) 1 — Supreme Court of Nigeria

Imagine winning your case at the trial court. Then winning again on appeal. Then winning a third time at the next appeal. And then, on the fourth attempt by your opponent, losing everything — not because the merits changed, but because nobody could prove that two extra people were sitting on the bench alongside the judge. Katsayel v. Abdullahi is a stark reminder that in some courts, procedural form can outweigh even three consecutive wins on the substance — and it produced a rare and forcefully argued dissent from one Supreme Court Justice who thought the whole thing was, in his words, most unfortunate.

The Facts

Two sisters, Hafsatu and Saida Katsayel, sued their brother, Auwalu Abdullahi, at the Sharia Court, Sandamu, in Katsina State, seeking the distribution of four farmlands and a house their late father had left behind. Their brother admitted inheriting property from their father but insisted that only two of the farmlands and the house were part of the shared estate — the other two farmlands, he claimed, had been gifted to him personally by their father during his lifetime.

The trial Sharia Court found that the brother produced no credible evidence to back up his claim of a personal gift, and it distributed all four farmlands and the house among him and his sisters, including the two appellants. The dispute began in 2006.

The Journey Through the Courts

The brother appealed to the Upper Sharia Court, which dismissed his appeal. He appealed again to the Sharia Court of Appeal, which also dismissed it. Undeterred, he took the case to the Court of Appeal — and there, for the first time, he raised an entirely new argument that had nothing to do with who owned what: he argued that the trial Sharia Court had never been properly constituted in the first place, because Katsina State law requires a Sharia Court to sit with an Alkali (judge) plus two members, and the record didn't clearly show all three present at every sitting. The Court of Appeal agreed, set aside the Sharia Court of Appeal's judgment, declared the entire trial process a nullity, and ordered the case retried from scratch at the Upper Sharia Court.

The sisters, having now lost after three straight wins, appealed to the Supreme Court.

The Court's Reasoning

A properly constituted court is not optional — it's one of the four pillars of jurisdiction. The Court restated the classic test for whether any court has the competence to hear a case: it must be properly constituted as to the number and qualifications of its members; nothing must legally bar it from exercising jurisdiction; every condition precedent to that jurisdiction must be fulfilled; and the case must have been brought by due process. Miss any one of these, and the court simply lacks the power to decide anything at all.

Under Katsina's Sharia Court Law, all three seats on the bench have to be filled — every time. Section 4(1) of the Sharia Court Law of Katsina State requires a Sharia Court to be presided over by an Alkali sitting with two members. The Supreme Court majority read this as meaning all three must be present at every sitting, not merely appointed to the court in general — with the Alkali playing the indispensable role of presiding, but the two members' presence being no less mandatory.

Missing evidence of attendance is treated as missing attendance. This was the decisive finding. Reviewing the trial record, the majority found that aside from the very first sitting on 10 July 2006 — where all three members were recorded as present — none of the seven subsequent sittings, right through to the delivery of judgment, carried any endorsement showing the two lay members were actually there. The Court held it could not simply assume or speculate that they had attended based on silence in the record. Where the law requires proof of proper constitution, the absence of that proof meant the requirement wasn't met.

A word not in the statute can't be read into it. The sisters had tried to argue that section 4(1) should be understood to include "assessors" as an alternative to the two named members — an argument the Court rejected outright as an impermissible attempt to import language the legislature never used. Statutes are to be interpreted as written, not rewritten to fit a party's preferred outcome.

Variation in a panel's membership isn't a technicality — it voids the whole proceeding. Where a statute requires a court to sit as a panel, the Court held, every member of that panel must be present at every sitting; any departure renders the proceeding a nullity, not merely irregular. On that basis, the seven defective sittings — including the one at which judgment was actually delivered — could not stand.

The Dissent

One member of the panel, Abiru, J.S.C., disagreed sharply enough to write a full dissent — and it's worth understanding why, because it shows just how differently the same trial record can be read.

Abiru, J.S.C. pointed to an entry in the concluding part of the Sharia Court's own judgment, where the presiding Alkali recorded that he had sat "with 2 members" in confirming the distribution of the inheritance. For Abiru, J.S.C., this entry was direct evidence, in the court's own words, that the two members were present when the case was actually decided — and courts reviewing native, customary, area, and Sharia court proceedings are supposed to look past questions of form (like whether every page carries three signatures) and focus on the substance of what the record actually shows happened.

Abiru, J.S.C. went further still, comparing the original Hausa-language record against its English translation, and found that the Hausa original named the two members who sat with the Alkali — M. Sa'idu Garba and M. Ahmed — names that had simply been dropped from the English version relied on by the Court of Appeal. Reading the document as a whole, rather than in isolated fragments, he concluded the trial court had, in fact, been properly constituted throughout.

He added two further points. First, that the presumption of regularity — the common-law principle that official and judicial acts are presumed to have been done correctly unless proven otherwise — should have applied in the trial court's favour, and that presumption can only be displaced by real evidence, not by assumption or conjecture, especially where nobody had even raised the quorum issue at any of the first three levels of the case. Second, and more pointedly, he stressed that Sharia law exists to achieve substantive justice, not to enforce rigid technical formality, and that courts sitting in Sharia matters ought to set aside common-law habits of prioritising form over substance. In his view, unwinding a twenty-year-old inheritance dispute on a technicality that had nothing to do with the actual rights and wrongs of the case was, in his own words, most unfortunate.

The Verdict

By a majority of four to one, with Abiru, J.S.C. dissenting, the Supreme Court dismissed the sisters' appeal, upholding the Court of Appeal's decision that the trial Sharia Court had not been properly constituted and that the case must be tried afresh at the Upper Sharia Court.

Key Takeaways

  • A statutorily required panel — judge plus lay members — must be shown to be fully present at every single sitting, not just appointed to the court in general. Silence in the record on a member's attendance can be treated as evidence they were not there.
  • Improper constitution of a court renders the entire proceeding a nullity, not a mere irregularity — even where the outcome on the merits was never in doubt.
  • Courts will not read words into a statute that the legislature didn't use, however sympathetic the argument for doing so might be.
  • How a court's record is read — form versus substance, translation versus original language — can decide a case. The same trial record produced opposite conclusions from the majority and the dissent.
  • The presumption of regularity of judicial acts is not automatic protection. Even where it exists, it must be argued and applied — and different judges can reasonably disagree on whether the record rebuts it.
  • A dissent, even when it doesn't carry the day, matters. It can preserve a different reading of the law and the facts for future courts to weigh — and here, it stands as a pointed reminder that procedural rules exist to serve justice, not the other way around.

Test

  1. What was the primary legal issues addressed by the Supreme court regarding the constitution of the sharia court?
  2. What was the basis of the dissenting opinion by Justice Habeeb Adewale Olumuyiwa Abiru, J.S.C?
  3. How did the Supreme court reconcile the interpretation of statutory panel requirements with the presumption of regularity?
