Preamble: Setting the Legal Investigative Parameters

The comprehensive legal dissection of the FRN v. Kanu case now turns to the most fundamental geographic limitation on state power: territorial jurisdiction [I.12, I.13]. The prosecution’s case hinges significantly on the actus reus—the criminal act—of broadcasts and statements made by Mazi Nnamdi Kanu while he was physically resident in foreign countries, such as the United Kingdom and Israel [I.2, I.11]. The core investigative question for Article IV is: Does the Nigerian criminal justice system possess the legal competence, under the Constitution and extant statutes, to prosecute a citizen for a political offence where the act of commission (the speech/broadcast) occurred entirely outside Nigeria's territorial sovereignty? This article will rigorously dissect the tension between the common law principle of strict territoriality and the state's assertion of jurisdiction based on the Protective and Effects Doctrines, guiding the reader to the appellate conclusion that these charges, pertaining to foreign acts, are legally unsustainable due to a lack of explicit legislative sanction.

I. The Foundational Mandate: Strict Territoriality in Nigerian Criminal Law

The bedrock of criminal jurisdiction in Nigeria, inherited from the English common law tradition, is the principle of strict territoriality. Our investigation must establish the parameters of this foundational rule.

A. The General Rule: Locus Delicti within the Sovereign State

Nigerian criminal law operates under a strong presumption that a crime is triable only where the prohibited act or omission (actus reus) took place [I.12].

1. Section 12 of the Criminal Code Act: This statute is the primary expression of the territorial rule, generally confining the application of the Criminal Code to offences committed wholly or substantially within Nigerian land, waters, or airspace [I.12]. The judiciary has traditionally enforced this rule to respect the sovereignty of other nations, acknowledging that the place where the accused is physically located determines the proper jurisdiction [I.17].
2. The Actus Reus of Words: In the context of Kanu's charges—Treasonable Felony and acts of Terrorism—the actus reus often involves the utterance, publication, or broadcast of words intended to incite or facilitate the commission of the offence [II.4]. Where Kanu’s words were spoken, recorded, and transmitted from a foreign jurisdiction, the locus delicti (place of the crime) for the act of speaking is fundamentally extraterritorial [I.11]. The challenge for the Nigerian state is to bridge this jurisdictional chasm.

B. The Constitutional Imperative of Defined Jurisdiction

Beyond statutory limitations, the Constitution itself demands that the jurisdiction of any court must be clearly defined by law [I.5, I.7].

1. Statutory Interpretation: The principle of strict construction dictates that penal statutes (laws defining crimes and punishments) must be interpreted narrowly in favour of the citizen [I.17]. Where a statute is ambiguous regarding its territorial reach, the court must lean against the assertion of extraterritorial jurisdiction.
2. Protecting Citizens: This strict interpretation is a constitutional safeguard, preventing the Executive from subjecting a citizen to Nigerian penal law for acts that were legally permissible in the foreign jurisdiction where they occurred, thus protecting the fundamental right to liberty and fair trial [I.4].

II. The State’s Assertion of Jurisdiction: Protective and Effects Doctrines

The Federal Government of Nigeria (FGN) sought to circumvent the strict territorial rule by invoking established exceptions in international criminal law, specifically the Protective Principle and the Effects Doctrine [I.14, I.15]. Our investigative lens must analyze the viability of these doctrines in Nigerian municipal law.

A. The Protective Principle and Crimes Against State Security

The Protective Principle asserts that a state can claim jurisdiction over acts committed anywhere in the world, by anyone, if those acts pose a direct and serious threat to the security, integrity, or fundamental sovereign interests of the state [I.15, I.16].

1. Application to Kanu: The FGN argued that Treasonable Felony [II.4] and Terrorism [I.19]—crimes that challenge the very existence of the state—fall squarely under this principle. The state cannot rely on foreign governments to prosecute acts that threaten its core existence [I.17].
2. The Case of Treason (Section 37): Critically, the Criminal Code itself grants explicit extraterritorial jurisdiction for the offence of Treason (the most severe security crime) by criminalizing conspiracy with any person, "either within or without Nigeria," to levy war against the state [I.13, I.18]. This explicit legislative sanction for Treason contrasts sharply with the lack of such explicit provision for Treasonable Felony or most acts of Terrorism under the pre-2022 law.

B. The Objective Territoriality Principle (Effects Doctrine)

The Effects Doctrine, or Objective Territoriality, asserts jurisdiction based on the location of the result of the crime, not the location of the act [I.14].

1. The FGN’s Argument on Broadcasts: The prosecution argued that Kanu’s broadcasts, even if initiated abroad, were intended to be and were in fact received and heard in Nigeria [I.14, I.20]. Furthermore, they claimed the broadcasts caused their essential harm—incitement to violence, disruption of public order, and the enforcement of "sit-at-home" orders—within Nigeria [I.20]. Therefore, a necessary component of the crime, the effect, occurred within the court’s territorial limits.
2. Evidential Burden: While conceptually powerful, the Effects Doctrine places a heavy evidential burden on the prosecution to prove, beyond a reasonable doubt, the direct, material, and causal link between the foreign words and the specific criminal acts within Nigeria [I.14, I.20]. This is often a significant hurdle in political speech cases.

III. The Jurisprudential Verdict: The Requirement for Explicit Statutory Sanction

The key to resolving the jurisdictional conflict over Kanu's foreign actus reus lies in the judiciary's role as the guardian of the principle of legality (nullum crimen sine lege).

A. The Court of Appeal’s Ruling on Territoriality

The Court of Appeal’s 2022 judgment did not just focus on the rendition; it fundamentally addressed and struck out the charges relating to foreign acts [I.13, I.17].

1. Lack of Enabling Statute: The Appellate Court held that the prosecution had failed to identify clear, unambiguous provisions in the relevant statutes (the Criminal Code or the Terrorism Prevention Act) that explicitly granted the Federal High Court extraterritorial jurisdiction for the specific crimes charged, especially Treasonable Felony [I.17].
2. Rejection of Wholesale Importation: The court refused to sanction the wholesale importation of the Protective or Effects Principles merely because the state asserted a security threat. Such a crucial expansion of criminal jurisdiction must come from the Legislature—the representative body of the people—and not be created by judicial fiat, particularly where the liberty of a citizen is at stake [I.17]. The court insisted on legislative clarity to prevent executive overreach.

B. The Doctrine of Expressio Unius Est Exclusio Alterius

The specific provision in the Criminal Code that grants extraterritorial jurisdiction for Treason (S. 37\) [I.18] works against the FGN’s argument on the other charges.

Legal Rationale: The legal maxim expressio unius est exclusio alterius (the expression of one thing is the exclusion of others) applies here: the fact that the legislature explicitly included "within or without Nigeria" for Treason (S. 37\) suggests that, by omission, they deliberately excluded* this extraterritorial reach for the lesser but related offence of Treasonable Felony (S. 41\) and other parts of the Criminal Code [II.4].
The Judicial Mandate: The judiciary cannot fill this legislative gap to the detriment of the accused. The failure of the National Assembly to explicitly provide for global jurisdiction in the charge of Treasonable Felony is a fatal flaw in the prosecution’s case against the foreign actus reus*.

IV. Conclusion: The Inevitable Nullity of Foreign Acts Charges

Our investigation concludes that the charges against Mazi Nnamdi Kanu rooted in a foreign actus reus—words spoken in a foreign country—are structurally defective and must be quashed for lack of territorial jurisdiction.

1. The Absence of a Clear Law: The state’s reliance on the general Effects or Protective Doctrines fails because Nigerian criminal jurisprudence mandates that an expansion of territorial jurisdiction must be enshrined in an explicit, unambiguous enabling statute [I.17].
2. Judicial Consistency Required: The appellate court must uphold its own precedent, which already struck out these charges [I.13]. The trial court’s subsequent re-assertion of jurisdiction, absent a clear legislative amendment or a definitive Supreme Court directive specifically sanctioning the Protective Principle for the lower charges, represents a judicial overreach.

The final remedy on appeal for these specific counts must be the permanent termination and discharge of the accused, based on the principle that the Nigerian State cannot prosecute political dissent using methods that violate the geographic limits of its own criminal law [I.17]. This re-affirmation of territoriality is vital to maintain legal certainty and protect Nigerian citizens from the arbitrary application of penal statutes abroad.

THE OFFICIAL NARRATIVE: JURISDICTION AND SECURITY

According to official statements, the state asserts jurisdiction over foreign-origin broadcasts by invoking security imperatives and the effects within Nigeria. Authorities frame the charges as necessary to prevent destabilization and argue that protective and effects principles justify action when core state interests are threatened. Critics note that without explicit legislative authorization, such reliance stretches beyond clear statutory limits.

KEY QUESTIONS FOR NIGERIA'S LEADERS AND PARTNERS

How will statutes be amended to clearly define when extraterritorial jurisdiction applies to political-speech-related offences? What evidentiary standards will link foreign speech to domestic harm beyond temporal correlation? How will courts ensure early review of territorial competence to avoid prolonged defective trials? What safeguards will prevent overbroad application of security doctrines to political dissent abroad?

TOWARDS A GREATER NIGERIA: WHAT EACH SIDE MUST DO

If the legislature codifies explicit extraterritorial reach for specified offences with narrow criteria, then prosecutors and courts can avoid jurisdictional reversals; if not, cases will remain vulnerable. If prosecutors demonstrate clear causal links and avoid generic appeals to effects, then confidence in convictions improves; failure invites quashment. If courts enforce strict construction on territorial reach at arraignment, then legal certainty rises; delay perpetuates uncertainty.
