Preamble: Setting the Legal Investigative Parameters

The conviction of Mazi Nnamdi Kanu by the Federal High Court (FHC) on 20 November 2025 [7] presents Nigerian jurisprudence with a moment of critical self-assessment. This Article is not merely a critique; it is an investigation into whether the court’s authority to impose punishment persisted after the foundational penal statute was repealed. The core investigative hypothesis is that the conviction suffers from an incurable jurisdictional defect, rooted in the court's reliance on the defunct Terrorism (Prevention) Act, 2013 (TPAA) [1], a law explicitly terminated by the Terrorism (Prevention and Prohibition) Act, 2022 (TPPA) [2]. Our objective is to guide the reader through the constitutional and statutory landscape to demonstrate why this error renders the entire judgment void ab initio [5, 6], thereby compelling a nullification on appeal. We shall transition from the general principles of legislative repeal to the specific, fatal misinterpretation of the TPPA’s savings clauses by the FHC.

I. The Foundational Jurisdictional Defect: An Incurable Crisis of Lex Fori

The judgment delivered by Justice J. K. Omotosho [7] is legally vulnerable because it fundamentally failed to satisfy the most elementary condition for judicial competence in criminal law: the requirement of a live, operative penal statute.

A. The Doctrine of Statutory Obliteration and Legislative Supremacy

At the heart of this investigative piece lies the legislative action of the National Assembly. By enacting Section 98(1) of the TPPA [2], the Assembly executed an express repeal of the TPAA [1]: "The Terrorism (Prevention) Act, No. 10, 2011 and the Terrorism (Prevention) (Amendment) Act, 2013 are hereby repealed." [2]

Under the constitutional doctrine of Legislative Supremacy, as affirmed by the Supreme Court in cases like A.G. Federation v. Sode [14], this clear, unambiguous command must be given full effect. The question then becomes: what is the legal effect of an express repeal on a pending criminal trial? The common law principle, incorporated into Nigerian jurisprudence, dictates that unless the repealing Act contains an explicit clause saving ongoing prosecutions, the repealed law ceases to exist for all forward-looking purposes, including the power to sustain a criminal charge at the point of judgment [6]. This is the essence of statutory obliteration.

B. The Collapse of the Lex Fori Pillar

Criminal law jurisdiction rests upon the concurrent satisfaction of two temporal conditions. The investigative focus here is on the second:

1. Tempus Delicti (Law at Time of Offence): The act must have been criminal when committed. (Satisfied by the TPAA [1] in 2016/2017).
2. Lex Fori (Law at Time of Conviction): The court’s authority to impose a sentence must be derived from a law in force at the date of judgment. (Failed catastrophically: The TPAA [1] was dead in 2025 [2]).

The failure of the Lex Fori test renders the proceedings fundamentally incompetent [5]. The FHC’s penal power is a delegated authority from the legislature; when the TPAA [1] was repealed, that delegation of power was withdrawn. The imposition of a penalty in 2025 was thus an exercise of power without a legal source, constituting a jurisdictional defect of the most serious kind, as established in Madukolu v. Nkemdilim [5].

II. The Legal Odyssey: Tracing the Jurisdictional Vulnerability

To understand the severity of the FHC's final error, one must trace the key legal milestones that made the case susceptible to the jurisdictional flaw.

A. The Contextual Legality of Flight (2015–2017)

The FHC's subsequent charges included ‘bail jumping.’ However, this charge must be viewed through the lens of the factual and legal context established by the Abia State High Court [8]. The judicial finding that the military operation targeting Kanu's residence was an illegal invasion and a violation of his fundamental rights [8] provides powerful legal justification for his flight. Jurists must investigate whether a person can be penalized for escaping a proven, unconstitutional threat to life and liberty. This contextual illegality provides a strong mitigating factor, undermining the moral and legal weight of the 'bail jumping' indictment.

B. Extraordinary Rendition and the Limits of Judicial Forgiveness (2021–2023)

The Supreme Court's decision to remit the case for trial following the illegal extraordinary rendition [7] was based on the doctrine that subject-matter jurisdiction survives illegal arrest [5, 18]. While this common law principle prevents the courts from rewarding illegal arrests with automatic acquittals, it did not—and could not—grant the FHC immunity from future statutory errors. The Supreme Court's ruling, focused on the legality of the arrest, left the legality of the statute open for investigation, creating the necessary conditions for the final, fatal error under the repealed law.

C. The Point of Legislative Override: Act of Repeal

The critical moment was the enactment of the TPPA in 2022 [2]. When the case was remitted to the FHC, the court had a mandatory duty to re-evaluate the charge sheet against the new, operative law (TPPA) [2]. Its failure to recognize that the Tempus Delicti (time of offence) was severed from the Lex Fori (law at time of judgment) by the 2022 repeal is the investigative focus, leading directly to the ultimate nullity in 2025 [6].

III. The Fatal Interpretative Fallacy: Misreading the Savings Clause

The primary defense for the conviction relies on the FHC’s contention that the TPPA [2] implicitly saved the criminal prosecution. Our investigation must now dissect why this argument fails, focusing on the strict rules of statutory construction.

A. The Failure to Find a Penal Savings Clause

We must first confirm the most obvious point: the TPPA [2] contains no explicit penal savings clause. Had the National Assembly intended to save ongoing criminal trials, it would have used clear language preserving "all pending prosecutions, liabilities, penalties, forfeitures, or punishments incurred" [6, 12]. The strategic omission of this standard, explicit language in the TPPA [2] is not an oversight; it is a binding act of legislative intent. Jurists are required to interpret penal statutes strictly; the absence of a savings clause must be construed in favour of the accused [5]. B. The Judicial Overreach: Stretching the Personnel Clause (S. 98(3)) The FHC’s reliance on Section 98(3) of the TPPA [3] is the clearest instance of judicial overreach: "A person appointed, employed, or engaged under the repealed enactment shall be deemed to have been appointed, employed, or engaged under this Act." [3]

This clause is purely administrative—a Personnel Transition Clause—intended to secure the jobs and salaries of civil servants moving from the old counter-terrorism framework to the new NCTC [3]. Our investigation reveals three critical interpretive errors in the FHC’s approach:

1. Strictissimi Juris and Purpose Limitation: The doctrine of strictissimi juris demands that a clause relating to penal liability must be interpreted narrowly. The FHC engaged in an expansive interpretation, forcing an administrative clause to perform a penal function. This is an impermissible conflation of distinct legal categories [5]. The saving of a prosecutor's employment cannot be legally equated with the saving of the indictment he carries.
2. Hierarchy Inversion: The court allowed a narrow, specific, non-penal clause (S. 98(3)) to override the explicit, general command of the repeal clause (S. 98(1)) [2]. This constitutes an inversion of the rules of statutory hierarchy and a violation of the separation of powers [9, 13].
3. Conflict with Interpretation Act (S. 6): Even under Section 6 of the Interpretation Act [12], general savings are precluded if a contrary intention appears. The FHC overlooked that the TPPA [2] contains substantial institutional changes (NCTC), which indicate a legislative intent to supersede the old regime entirely, thus creating the necessary contrary intention to defeat a general saving of criminal proceedings.

IV. TPAA vs. TPPA: Investigating Substantive Discontinuity

The counter-argument—that the TPPA [2] was a mere technical re-enactment of the TPAA [1]—must be rigorously tested against the textual evidence of the statutes themselves. If the laws are substantively different, the FHC’s continuity argument collapses.

A. Substantive Change I: The Exemption for Fundamental Rights

Our investigation reveals a critical substantive change that fundamentally differentiates the two Acts:

* The TPAA [1] was silent on the protection of fundamental rights in the context of terrorism definitions.
* The TPPA [2] explicitly includes a protective proviso in Section 2(3) stating that an act done in the exercise of peaceful assembly, association, or expression shall not constitute an act of terrorism.

This is a legislative shield directly relevant to Kanu’s charges, which often relate to broadcasts and mass mobilization [7]. By convicting under the TPAA [1], the FHC denied Kanu the benefit of this clearer, more protective legislative mandate.

B. The Mandate to Apply the Favorable Law (Nyame Principle)

The established principle in Nigerian law, affirmed in Nyame v. Federal Republic of Nigeria [11], is that where a penal law changes between the commission of the offence and conviction, the accused must be given the benefit of the more favourable provision of the new law. The TPPA's [2] explicit protection for free expression is undeniably more favourable. The FHC's insistence on using the dead TPAA [1] was a direct violation of the Nyame principle [11], confirming the judicial error was one of both jurisdiction and miscarriage of justice.

C. Institutional and Definitional Overhaul

The TPPA’s [2] identity as a new law is confirmed by institutional and definitional expansion:

1. NCTC Centralization: The TPPA [2] formally creates the National Counter-Terrorism Centre (NCTC), centralizing operational authority and signifying a definitive break from the previous framework managed primarily by the ONSA [2].
2. FATF Compliance: The TPPA [2] includes detailed new provisions on proliferation financing and enhanced requirements for anti-money laundering compliance to meet international FATF standards [2]. This comprehensive expansion into international financial crime demonstrates that the TPPA [2] is a distinct, new penal regime.

The cumulative weight of these differences conclusively proves that the FHC could not assume seamless continuity between the TPAA [1] and the TPPA [2].

V. The Constitutional Hammer: Investigating the Violation of Section 36(8)

Beyond the statutory defect, our investigation must demonstrate how the FHC’s action breached the constitutional guarantee against arbitrary punishment.

A. The Principle Against Retroactivity: Section 36(8)

Section 36(8) of the 1999 Constitution [4] states: "No person shall be held to be guilty of a criminal offence... that did not, at the time it took place, constitute such an offence; and no penalty shall be imposed for any criminal offence heavier than the penalty in force at the time the offence was committed." [4] The critical phrase for juristic investigation is "penalty in force." Once the TPAA [1] was repealed by the legislature in 2022 [2], its penalties ceased to be "in force". The FHC’s attempt to impose them in 2025 gave the defunct law retrospective effect to cover the period between the repeal and the judgment. This judicial resurrection of a dead statute for penal purposes is precisely the mischief Section 36(8) [4] is designed to prevent, making the punishment arbitrary and unconstitutional.

B. The Usurpation of the Legislative Function (Lakanmi Principle)

The FHC’s act of defying the express repeal (S. 98(1)) [2] and enforcing the dead TPAA [1] constitutes a judicial invasion of the legislative domain [13]. If the judiciary can selectively ignore a repeal when it suits the ends of a specific prosecution, the constitutional allocation of power, where the National Assembly makes the law and the judiciary applies the law, collapses. This is not merely an error of law; it is a constitutional crisis concerning the separation of powers [9]. .

C. Breach of the Right to Certainty (Section 36(1))

A central component of the right to a fair hearing (Section 36(1)) [10] is the guarantee of certainty in penal law (Lex Certa). The FHC’s reliance on the repealed TPAA [1] introduced fatal legal vagueness. The accused was tried and convicted under a statute that was not part of the current, enforceable corpus juris—a law that the public and the legal profession could not definitively confirm as "in force." This uncertainty is antithetical to the rule of law and constitutes a profound denial of justice [10].

VI. Comparative Jurisprudence: The Doctrine of Actio Personalis Moritur Cum Statuto

To further educate the reader, we must place the Nigerian FHC’s error within the broader context of common law jurisprudence regarding repealed statutes.

A. The Common Law Rule of Extinction

The common law doctrine, actio personalis moritur cum statuto (a personal action dies with the statute), confirms that the repeal of a penal statute terminates the pending prosecution unless expressly saved [16]. This rule is a long-established pillar of legal stability, preventing courts from prosecuting actions based on obsolete legislative policy. The FHC's failure to adhere to this principle places the Nigerian justice system outside the established legal norms of the Commonwealth [16]. B. True Savings Clauses vs. Administrative Transition Clauses Legal treatises across jurisdictions consistently differentiate between the clauses relied upon:

* Penal Savings Clauses are explicit, detailed provisions focusing on preserving legal effects (e.g., "Any offence committed... may be punished") [12].
* Administrative Transition Clauses (like TPPA S. 98(3) [3]) are focused on practical continuity (e.g., staff, contracts, assets).

The FHC’s error was failing to apply this crucial distinction. It confused a clause focused on personnel (who works) with a clause focused on jurisdiction (what law governs punishment), resulting in a profound category error.

VII. Appellate Mandate: The Inviolable Authority of Nullity

Our investigative conclusion is that the error is jurisdictional, meaning the appellate court's discretion is severely limited. It is mandated to declare the proceedings null.

A. The Binding Authority of Ogundimu v. The State
The most authoritative legal precedent guiding the appellate court is the Supreme Court’s ruling in Ogundimu v. The State [6]. This case holds unequivocally that a conviction pronounced under a law that has been repealed at the time of judgment is a legal nullity that must be set aside. This precedent is binding on all lower courts, including the Court of Appeal, under the doctrine of stare decisis [20].

B. The Non-Curable Defect of Void Ab Initio

The FHC's judgment is not merely voidable (capable of being reversed due to error) but void ab initio (deemed to have never existed due to fundamental lack of competence) [5]. A defect of jurisdiction, such as the absence of a live penal statute, cannot be cured by the appellate court [19]. The appellate court cannot simply amend the conviction to read the TPPA [2] because this would violate the accused's right to be tried specifically on the new charge [6].

C. The Prohibition Against Oppressive Retrial

While the appellate court retains discretion to order a retrial, such an order would be contrary to justice in this case. A retrial is barred where: (a) the original trial was a nullity; (b) the order would lead to oppression or a miscarriage of justice [6]. Given the foundational nullity (dead law), the prior procedural abuses (illegal rendition [7]), and the protracted nature of the case, ordering Kanu to face a trial under the correct, subsisting TPPA [2] now would be seen as punitive rather than corrective. The only constitutional remedy is to quash the conviction and order final discharge.

VIII. Conclusion and Public Education Imperative

This investigative article has demonstrated, through rigorous legal analysis and reference to binding authorities, that the conviction of Mazi Nnamdi Kanu rests on a fatal jurisdictional flaw: the judicial application of a legislatively repealed statute [2, 6]. The Federal High Court’s error—the transmutation of an administrative jobs-saving clause into a penal conviction-saving instrument—constitutes an unconstitutional act of judicial legislation [13].

The implication extends far beyond this individual case: the failure to quash this conviction would signal that the judiciary is willing to undermine the separation of powers and sacrifice the certainty of Nigerian penal law for the sake of securing a state conviction [9]. The appellate court's duty is clear: to adhere to the mandate of Ogundimu [6], enforce the principle of Nullum Poena Sine Lege [4], and ensure that justice is delivered only under the living, operative law of the land.

THE OFFICIAL NARRATIVE: LEGAL POSITION AND PROCESS

According to official statements, the prosecution approach relied on continuity between the repealed TPAA and the TPPA, emphasizing public safety and administrative savings clauses to justify ongoing trials. Authorities frame the repeal as an institutional transition rather than a bar to pending prosecutions, citing national security imperatives and the need to avoid gaps in counter-terrorism enforcement. Critics counter that no explicit penal savings clause exists to preserve jurisdiction.

KEY QUESTIONS FOR NIGERIA'S LEADERS AND PARTNERS

How will future repeals specify the treatment of pending prosecutions to avoid jurisdictional voids? What safeguards ensure courts verify operative law at judgment before convictions are entered? How will prosecutorial guidelines be updated to refile under current statutes when laws change? What transparency will accompany legislative transitions to prevent administrative clauses from being stretched into penal savings?

TOWARDS A GREATER NIGERIA: WHAT EACH SIDE MUST DO

If the National Assembly drafts repeal clauses with explicit language on pending prosecutions, then courts and prosecutors can avoid nullities; if not, convictions risk collapse. If prosecuting authorities re-audit charges upon statutory change and lay fresh counts under the operative law, then defendants’ fair-trial rights and public confidence improve; failure sustains legal uncertainty. If the judiciary applies strict construction to penal savings and rules early on repeal effects, then legal certainty increases; delay perpetuates inconsistency.
