Judicial review is the High Court's power to examine the legality, fairness and rationality of a decision taken by an administrative authority — here, the Commissioner-General of the Zimbabwe Revenue Authority (ZIMRA) or a customs officer acting under the Customs and Excise Act [Chapter 23:02] (the "C&E Act") — and to set that decision aside, or compel its proper exercise, where the authority has acted unlawfully, unfairly or unreasonably. It is the constitutional backstop of the entire customs appeal system, and it is the final node on the dispute-resolution map we have been building across the last two modules. Having studied the Customs Appeals routing map (which decision goes to which forum) and then descended into the Fiscal Appeal Court (the specialised tribunal for classification disputes), we now arrive at the remedy that catches everything the dedicated appeal routes cannot reach: judicial review of customs administrative action in the High Court.
The single most important idea in this lesson is the distinction between appeal and review. An appeal asks: was the decision right? — it re-opens the merits, substitutes a correct answer for a wrong one, and is available only where a statute grants it (for example, classification to the Fiscal Appeal Court under Section 87 of the C&E Act, or valuation to the High Court under Section 119 after payment). Review, by contrast, asks a narrower and more fundamental question: was the decision lawfully and fairly made? — it scrutinises the process and the power, not the wisdom of the outcome, and it is available as of constitutional right against virtually every administrative decision, even those the C&E Act declares "final". Judicial review does not ask whether the Commissioner classified the goods correctly; it asks whether the Commissioner had the power to decide, heard the affected party, gave reasons, took into account only relevant considerations, and reached a decision a reasonable authority could reach.
The governing law sits in three layers. At the apex is Section 68 of the Constitution of Zimbabwe (Amendment (No. 20) Act, 2013), which guarantees every person the right to administrative conduct that is lawful, prompt, efficient, reasonable, proportionate, impartial and procedurally fair, and the right to be given written reasons for administrative action that adversely affects them. Beneath the Constitution, the Administrative Justice Act [Chapter 10:28] (the "AJA") codifies those duties and gives the High Court an express statutory power to grant relief by way of review. Beneath the AJA, the High Court Act [Chapter 7:06] preserves the Court's long-standing common-law review jurisdiction and its established grounds of review, and the High Court Rules, 2021 prescribe the court-application procedure by which a review is brought. Because the precise section and rule numbers of these non-customs statutes are not contained in the customs source set used for this lesson, the load-bearing provisions are stated and flagged for verification where their exact numbering is asserted.
The reviewable terrain in customs is large, and it is defined by what the dedicated appeal routes leave behind. Where the C&E Act provides a tailored remedy, the trader must normally use it and review is excluded: classification goes to the Fiscal Appeal Court (Section 87, excise mirror Section 96); valuation goes to the High Court on appeal after payment (Section 119); an admission fine imposed by a junior officer is appealed to the Commissioner (Section 200(8)); a court-ordered forfeiture is appealed "as if it were a conviction" (Section 209(6)); and a seizure is challenged by instituting proceedings within three months (Section 193(12)). But a great many customs decisions have no dedicated appeal — and these are the natural home of judicial review: a refusal of a new licence, which the Act routes to the President and declares "final" (Section 133); a refusal to renew or a cancellation of a licence, routed to the Minister and likewise declared "final" (Section 134(3)); a suspension of a licence (Section 135); a refusal, suspension or revocation of Authorised Economic Operator status (Section 216B); a post-clearance audit redetermination of origin, preference or rebate entitlement and the penalties that follow it (Section 223A); a discretionary remission or refusal of remission of duty (Section 120(3)); and the daily exercise of discretion in risk-targeting, detention and release. The word "final" in Sections 133 and 134(3) bars a further appeal on the merits — it does not oust the High Court's constitutional review jurisdiction, because under the supremacy of the Constitution no ordinary statute can immunise administrative action from review for legality and fairness.
The grounds of review are conventionally grouped into the three families crystallised in the leading (and, in Zimbabwe, persuasive) English authority Council of Civil Service Unions v Minister for the Civil Service [1985] AC 374 — the "GCHQ" case: illegality (the authority misunderstood or exceeded its powers — ultra vires, error of law, improper purpose, irrelevant considerations, unlawful sub-delegation, fettering of discretion); irrationality (the decision is so unreasonable that no reasonable authority could have reached it — the Wednesbury standard from Associated Provincial Picture Houses v Wednesbury Corporation [1948] 1 KB 223); and procedural impropriety (breach of the rules of natural justice — audi alteram partem, the right to be heard, and nemo iudex in causa sua, the rule against bias — and failure to observe a mandatory procedure, including the duty to give reasons). Section 68 of the Constitution and the AJA gather these into the modern Zimbabwean formula of lawful, reasonable and procedurally fair administrative conduct, supplemented by the doctrine of legitimate expectation.
Three procedural gateways are decisive and frequently fatal if missed. First, the doctrine of exhaustion of domestic remedies: a litigant who has an adequate internal or statutory remedy (an objection to the Commissioner, an appeal to the Fiscal Appeal Court, an appeal to the Minister) must ordinarily exhaust it before seeking review; the courts will entertain review despite an unexhausted remedy only in exceptional cases (a clear want of jurisdiction, gross irregularity, or where the statutory remedy is not adequate). Second, Section 196 of the C&E Act erects a notice-and-limitation barrier in front of any litigation against the State, the Commissioner or an officer: no civil proceedings may be instituted until sixty days after notice has been given under the State Liabilities Act [Chapter 8:15] (Section 196(1)), and the proceedings must be brought within eight months after the cause of action arose (Section 196(2)), failing which they are time-barred and the unsuccessful litigant faces a full-indemnity costs exposure. Third, review itself must be brought without undue delay: even within the eight-month window, an unexplained or unreasonable delay is itself a discretionary bar to relief.
The remedies are equally distinctive. On review the High Court does not generally substitute its own decision for the Commissioner's — it sets the decision aside and refers the matter back to be taken again, lawfully and fairly (the same "refer-back" posture we saw the Fiscal Appeal Court adopt for classification under Section 18(7) of the Fiscal Appeal Court Act [Chapter 23:05]), reflecting the principle that the administrator, not the judge, is the chosen decision-maker. The Court may also grant a declarator (declaring the legal position), a mandamus (a mandatory order compelling the authority to perform a duty — for example, to decide an application it has unlawfully sat on, or to furnish reasons), a prohibitory interdict (restraining unlawful action), and, crucially in customs, an interim interdict staying enforcement, sale of seized goods, or collection while the review is heard — because customs operates on a pay-now-argue-later logic and a review does not automatically suspend the duty demand. This lesson walks each of these layers clause by clause, traces the end-to-end procedure of mounting a customs review in the High Court, works the quantum at stake in a post-clearance audit dispute to show why and when review is worth pursuing, and closes the Customs Appeals trilogy by tying the whole dispute-resolution architecture together.
