The Constitutionalization of Administrative Justice: The Application of the Audi Alteram Partem Rule in Tax and Social Security Law in Zimbabwe
Overview
The audi alteram partem rule (“hear the other side”) is a foundational pillar of natural justice and the rule of law. Historically conceptualized as a common law constraint on arbitrary decision-making, it has undergone a profound transformation in Zimbabwe. Since the promulgation of the Constitution of Zimbabwe Amendment (No. 20) Act, 2013, natural justice is no longer merely an interpretative aid or a residual common law remedy; it has been elevated to a supreme, non-derogable constitutional right.
This article explores the application of the audi alteram partem rule to statutory public bodies, focusing specifically on the National Social Security Authority (NSSA) and the Zimbabwe Revenue Authority (ZIMRA). Through an examination of the Constitution, the Administrative Justice Act [Chapter 10:28], statutory tax and pension frameworks, and Zimbabwean case law, this treatise analyzes how the right to be heard acts as a critical check on state authority, even where fiscal preservation is prioritized.
Introduction: The Nature and Origin of Audi Alteram Partem
The maxim audi alteram partem—literally meaning “hear the other side” or “no person should be condemned unheard”—is of ancient origin. It dictates that any decision-maker, when exercising public or statutory power that may prejudicially affect the rights, interests, or legitimate expectations of an individual or corporate entity, must afford that party a fair and reasonable opportunity to present their case before a final decision is made.
In the administrative sphere, the rule comprises three essential components:
- Adequate Notice: The subject must be given clear and timely notice of the proposed administrative action, the grounds on which it is based, and the potential consequences.
- A Fair Hearing: The subject must be allowed to make representations, submit evidence, and counter any adverse allegations.
- Duty to Consider: The decision-maker must genuinely and open-mindedly consider the representations made before exercising their statutory power.
In the realms of taxation and social security administration, statutory bodies such as ZIMRA and NSSA are granted extraordinary coercive powers. They can unilaterally raise assessments, impose penalties, demand immediate payment, and even issue third-party garnish orders against bank accounts. In this high-stakes environment, the audi alteram partem rule serves as a critical constitutional shield, ensuring that “fiscal discipline” and “administrative efficiency” do not descend into administrative tyranny.
The Constitutional Framework of Administrative Justice in Zimbabwe
Section 68 of the Constitution: The Supreme Mandate
Prior to 2013, the right to a fair hearing in administrative matters was primarily protected by common law, supplemented by ordinary acts of Parliament. The 2013 Constitution altered this landscape by codifying administrative justice as a fundamental human right.
Section 68(1) of the Constitution of Zimbabwe provides:
“Every person has a right to administrative conduct that is lawful, prompt, efficient, reasonable, proportionate, impartial and both procedurally and substantively fair.”
Section 68(2) mandates that any person whose rights, freedom, interest, or legitimate expectation has been adversely affected by administrative conduct has the right to be given prompt, written reasons for the action.
The constitutionalization of this right has profound legal implications:
- Supremacy over Statutes: By virtue of Section 2 of the Constitution, any statutory provision, regulation, or administrative practice that purports to deny a person the right to be heard before an adverse decision is made is unconstitutional and void to the extent of its inconsistency.
- Broader Scope: The constitutional right applies not only to vested “rights” (e.g., property or freedom) but also to “interests” and “legitimate expectations.” This is crucial for businesses whose commercial operations or financial planning may be disrupted by a sudden penalty assessment.
The Administrative Justice Act [Chapter 10:28] (AJA)
The AJA is the enabling legislation enacted to give effect to the constitutional right to administrative justice. Under Section 3(1) of the AJA, an administrative authority that takes administrative action which may indeed affect the rights, interests, or legitimate expectations of any person must:
- Act lawfully, reasonably, and in a procedurally fair manner;
- Give the affected person adequate notice of the nature and purpose of the proposed action;
- Afford the person a reasonable opportunity to make representations; and
- Give adequate reasons for its action.
Where an authority fails to comply, Section 4 of the AJA empowers the High Court to review the decision, set it aside, or direct the administrative authority to act in accordance with the law.
Applying the Rule to the National Social Security Authority (NSSA)
NSSA is established under the National Social Security Authority Act [Chapter 17:04]. It is a statutory body corporate tasked with administering national social security schemes. To enforce compliance, NSSA is armed with powerful statutory instruments, notably Statutory Instrument 169 of 2021 and Statutory Instrument 64 of 2022, which govern the electronic submission of payroll data (Form P4) and the payment of contributions.
An employer who fails to submit a monthly P4 return or pay contributions on time is subject to severe statutory penalties, including daily compounding Level 3 fines.

Strict Constitutional Statutory Right
Requirement (Sec 68) under AJA (Sec 3)
How Audi Alteram Partem Restricts NSSA’s Penalty Regimes
NSSA frequently seeks to impose late-submission penalties automatically via its online portal. When the portal crashes or experiences systemic downtime, preventing employers from uploading their P4 forms, NSSA’s automated systems have historically still generated daily penalty fees.
Under the audi alteram partem rule, NSSA cannot lawfully enforce these automated assessments without affording the employer procedural fairness:
- The Right to Dispute the Factual Basis: Before a penalty can be legally recorded as a final, recoverable debt, the employer must be notified of the proposed penalty and allowed to submit evidence showing that the failure was caused by NSSA’s own portal failure (lex non cogit ad impossibilia—the law does not compel the impossible).
- Strict Compliance with Audits: Under Section 24 of the NSSA Act, inspectors have the power to enter premises and audit books. If an inspector identifies arrears and imposes penalties, they must present their preliminary audit findings to the employer first. The inspector cannot simply draft an assessment and issue a garnish order without allowing the employer to review, dispute, or reconcile the figures.
- The Exercise of Discretionary Waiver: The NSSA Act grants the Authority the discretion to waive penalties in “special circumstances.” If NSSA adopts a blanket policy of refusing to hear waiver applications, it violates the audi alteram partem rule. An administrative body must hear representations on why a waiver should be granted in each individual case; failing to do so constitutes a failure to exercise a statutory discretion, which is a grounds for review under the AJA.
The Rule in Tax Administration: ZIMRA and the Tax Laws
The relationship between the taxpayer and the Zimbabwe Revenue Authority (ZIMRA) is primarily governed by the Income Tax Act [Chapter 23:06], the Value Added Tax (VAT) Act [Chapter 23:12], and the Revenue Authority Act [Chapter 23:11].
Taxation is inherently coercive. To ensure the uninterrupted flow of state revenue, tax statutes contain provisions that appear to limit the audi alteram partem rule—often referred to as the “pay now, argue later” principle. However, the courts have consistently maintained that these statutory mechanisms must still yield to constitutional standards of administrative justice.
The “Pay Now, Argue Later” Principle vs. Natural Justice
In tax law, the “pay now, argue later” rule (reflected in provisions such as Section 69 of the Income Tax Act) dictates that once ZIMRA issues an assessment, the obligation to pay the tax is not suspended by the taxpayer filing an objection or an appeal to the Fiscal Appeal Court.
On its face, this principle appears to conflict with the audi alteram partem rule because the state takes the taxpayer’s property before a final determination is made by a court. However, the courts have reconciled this conflict by distinguishing between prior administrative hearings and post-decisional judicial reviews:
- The Temporary Limitation: The limitation on the right to be heard is deemed constitutionally permissible under Section 86 of the Constitution (the General Limitation Clause) because it serves a compelling public purpose: preventing taxpayers from using frivolous appeals to delay paying their taxes, which would paralyze the state fiscus.
- The Procedural Lifeline: Even under “pay now, argue later,” ZIMRA is not exempt from the audi alteram partem rule. Before ZIMRA issues an assessment resulting from an audit, it must send the taxpayer a “Letter of Audit Findings” or a “Notice of Intent to Assess.” The taxpayer must be given a reasonable timeframe (usually 14 to 30 days) to respond, explain their tax positions, and dispute the auditor’s interpretations. Only after considering these representations can ZIMRA lawfully issue a final assessment.
The Legality of Third-Party Garnish Orders
Under Section 58 of the Income Tax Act, the Commissioner-General of ZIMRA has the power to appoint any person (typically the taxpayer’s bank) to be the taxpayer’s agent and pay outstanding taxes directly from the taxpayer’s funds.
Historically, ZIMRA routinely issued these “garnish orders” silently, freezing corporate bank accounts without any prior notice to the taxpayer. This practice has been heavily litigated and declared unlawful precisely because it violates the audi alteram partem rule. The courts have established that:
- ZIMRA must first notify the taxpayer of the outstanding liability.
- ZIMRA must give the taxpayer an opportunity to show cause why a garnish order should not be issued or to propose an alternative payment plan.
- A sudden, unannounced garnish order that paralyzes a business without prior administrative recourse is a gross violation of Section 68 of the Constitution and the AJA.
Landmark Zimbabwean Case Law Analysis
The development of the audi alteram partem rule within Zimbabwean tax and administrative law has been defined by several key judgments from the High Court and the Supreme Court.

1. Metcash Trading (Zimbabwe) (Pvt) Ltd v Commissioner of Taxes (HH 179-02)
In this case, the High Court dealt with a situation where the Commissioner had issued garnish orders against the taxpayer’s bank accounts without affording them an opportunity to contest the underlying assessments.
- The Ruling: The court held that while the state has a legitimate interest in collecting revenue, the unilateral and secret issuance of garnish orders violates the common law audi alteram partem rule.
- Significance: The court confirmed that the newly enacted Administrative Justice Act applied to tax administrators. ZIMRA could not bypass the requirement to give notice and receive representations before taking drastic recovery measures that could shut down a business.
2. Bindura Nickel Corporation Ltd v Zimbabwe Revenue Authority (HH 30-08)
Although this case is widely known for establishing that the in duplum rule does not apply to tax debts, it also contains vital lessons on procedural fairness and administrative engagement:
- The Facts: ZIMRA had engaged in extensive bilateral meetings and communication with BNC regarding the tax audits of its subsidiaries. ZIMRA subsequently sought to argue that BNC had no standing and that the administrative arrangements were unilateral.
- The Ruling: Chatukuta J observed that because ZIMRA had actively engaged BNC, held meetings with its management, and accepted BNC’s proposal to hold back its VAT refunds, ZIMRA was bound by the representations and procedural agreements made during those meetings.
- Significance: The judgment shows that when a tax administrator engages in administrative dialogue, it cannot unilaterally alter the rules of that engagement without violating procedural fairness. The courts will hold administrators to the standards of mutual engagement.
3. Chirimuta v National Social Security Authority (HH 291-17)
In this matter, an employer challenged NSSA’s practice of automatically generating penalties and taking recovery action without allowing the employer to raise objections regarding systemic failures in the NSSA portal.
- The Ruling: The High Court ruled that NSSA’s automatic penalty generation system, which did not provide a mechanism for manual human review of genuine employer grievances, violated the right to administrative justice.
- Significance: The court emphasized that technology cannot be used as an excuse to bypass the Constitution. If NSSA uses electronic portals (such as the P4 portal), it must provide a clear, fair administrative channel for employers to raise objections and have those objections heard before penalties are enforced.
Procedural Guidelines for Challenging NSSA and ZIMRA Assessments
When an employer or taxpayer is faced with a penalty, surcharge, or tax assessment that has been raised without proper adherence to the audi alteram partem rule, they have specific legal remedies under Zimbabwean law.
Step 1: File a Formal Objection / Representation
The taxpayer must immediately file a formal objection in writing.
- For ZIMRA: This is done in terms of Section 62 of the Income Tax Act or Section 32 of the VAT Act. The objection must clearly state the grounds of the dispute, highlighting any procedural failures (such as a lack of a Letter of Audit Findings).
- For NSSA: The employer should submit a written representation to the General Manager or the regional compliance office, requesting a formal review of the penalty and attaching evidence of the portal failure or compliance obstacle.
Step 2: Request the Suspension of the Debt / Penalty
Because of the “pay now, argue later” rule, the taxpayer must formally apply for a suspension of the obligation to pay pending the determination of the objection.
- Under Section 69 of the Income Tax Act, the Commissioner has the discretion to suspend payment. The taxpayer must argue that forcing immediate payment would cause irreparable financial harm (such as insolvency) and that ZIMRA’s failure to afford them a proper prior hearing makes the assessment prima facie invalid.
Step 3: Invoke the Administrative Justice Act (AJA)
If NSSA or ZIMRA ignores the objection, refuses to provide written reasons, or proceeds to garnish bank accounts without responding, the business can approach the High Court for an Urgent Chamber Application.
- The application should seek an interdict to stay the garnish order or penalty enforcement on the grounds that the authority has violated Section 68 of the Constitution and Section 3 of the AJA.
- The court will look at whether the applicant was given:
- Adequate notice.
- A reasonable opportunity to make representations.
- Prompt, written reasons.
Step 4: Appeal to Specialized Tribunals
If the administrative authority formally rejects the objection, the taxpayer can appeal to:
- The Fiscal Appeal Court (for tax matters under ZIMRA).
- The High Court (for administrative decisions under NSSA).
Comparative Analysis: Zimbabwean Legislation on Administrative Hearings
The table below outlines how different Zimbabwean tax and social security laws incorporate, limit, or interact with the audi alteram partem rule:
| Legislation / Statute | Key Section | Impact on Audi Alteram Partem | Legal Recourse for Failure to Hear |
| Constitution of Zimbabwe | Section 68 | Elevates procedurally and substantively fair administrative conduct to a non-derogable constitutional right. | Urgent Chamber Application to the High Court for constitutional relief. |
| Administrative Justice Act [Chapter 10:28] | Section 3 & 4 | Dictates the mandatory steps for a fair hearing (notice, representation, duty to provide reasons). | Application for Judicial Review in the High Court to set aside the decision. |
| Income Tax Act [Chapter 23:06] | Section 58 (Garnish) & Section 62 (Objections) | Authorizes third-party garnish orders; however, common law dictates that these cannot be executed silently without prior warning. | Filing of an objection; appeal to the Fiscal Appeal Court; AJA review of garnish orders. |
| NSSA Act [Chapter 17:04] | Section 24 & SI 169/2021 | Allows inspectors to raise assessments and penalties for late P4 returns; requires human review of portal-based errors. | Written appeal to the NSSA Board/General Manager; Judicial Review in the High Court. |
| VAT Act [Chapter 23:12] | Section 32 | Establishes the right to object to assessments; requires ZIMRA to issue written determinations on objections. | Appeal to the Fiscal Appeal Court. |
Conclusion
The evolution of Zimbabwean law has made one reality clear: public administrative bodies are not above the law. While the state has protected itself from commercial defenses like the in duplum rule to preserve the public fiscus, it has simultaneously bound its administrators to the highest standards of constitutional fairness.
For businesses operating in Zimbabwe, the audi alteram partem rule is the most potent legal weapon against arbitrary, punitive, or technologically flawed assessments issued by ZIMRA and NSSA. An automated system cannot unilaterally declare an employer a defaulter without providing a human forum to dispute the facts.
To safeguard their operations, corporate executives must:
- Document Everything: Maintain meticulous records of system failures, email correspondence with help desks, and proof of attempt to file returns.
- Act Decisively: The moment a penalty is proposed, initiate the audi alteram partem process by filing a formal objection. Do not wait for a garnish order.
- Assert Constitutional Rights: If NSSA or ZIMRA acts arbitrarily, utilize the Administrative Justice Act to compel these authorities to act lawfully, reasonably, and fairly. The fiscus must be preserved, but never at the expense of the Constitution.
