Delta Beverages (Private) Limited v Zimbabwe Revenue Authority

Delta Beverages (the Applicant) challenged tax assessments issued by the Zimbabwe Revenue Authority (the Respondent) for the period March 2019 to October 2021. The Respondent had issued assessments requiring payment of tax obligations in foreign currency, and threatened to garnish the Applicant's bank accounts as a collection measure. The Applicant initially sought a provisional order interdicting the Respondent from instituting collection measures and garnishing accounts, and sought a declaration that the Respondent should complete the audit process taking into account all ZWL (local currency) transactions and payments, and thereafter issue final assessments. The matter was initially filed as an urgent application but was later removed from the urgent roll by consent on 21 June 2024 and referred to the opposed roll. The same issues regarding the validity of these tax assessments had previously been litigated in HH577/23 (where the High Court dismissed the Applicant's objections to the assessments) and subsequently in SC62/24 (where the Supreme Court dismissed the Applicant's appeal and confirmed the validity of the assessments requiring payment in foreign currency).

• Whether the doctrine of issue estoppel applied to bar the present application given that the same questions had been decided in prior judgments HH577/23 and SC62/24
• Whether the relief sought by the Applicant was competent
• Whether the Applicant failed to exhaust domestic remedies before approaching the court
• Whether tax assessments issued by the Respondent requiring payment in foreign currency were valid
• Whether the Applicant was entitled to have its local currency payments revalued and taken into account

A. The point in limine of issue estoppel be and is hereby upheld. B. Consequently, the application be and is hereby dismissed with costs.

Issue estoppel applies where: (1) the same question has been decided in prior litigation; (2) the judicial decision said to create the estoppel was final; and (3) the parties to the judicial decision are the same as the parties to the proceedings in which the estoppel is raised. Once these requirements are satisfied, a party cannot re-litigate the same issues, even if packaged differently in new relief sought. The doctrine of stare decisis requires lower courts to be bound by decisions of superior courts on points of law, and such decisions cannot be subjected to further examination by the same or lower courts. A party seeking to avoid issue estoppel bears the burden of showing good cause why the doctrine should not apply. Attempts to indirectly challenge the validity of matters already judicially determined through new applications constitute an abuse of court process and will be dismissed.

The court noted that issue estoppel is not part of Roman-Dutch law but was borrowed from English law, though it has been embraced by Zimbabwean courts in the wider application of existing law in light of current modes of thought. The court observed that the Applicant's arguments against issue estoppel were not merited because they sought to raise matters that were either already before the previous courts or arose as a consequence of the Applicant's own erroneous interpretation of tax legislation as found by those courts. The court commented that no submissions were made by the Applicant to persuade the court to depart from the usual practice of costs following the outcome. The court also noted it was unnecessary to determine the other points in limine raised by the Respondent once issue estoppel was upheld.

This case demonstrates the robust application of the doctrine of issue estoppel in Zimbabwean law to prevent re-litigation of matters already finally determined by competent courts. It affirms that parties cannot circumvent binding judicial decisions by repackaging the same disputes in different relief sought. The judgment reinforces the principles of finality in litigation and stare decisis, particularly emphasizing that lower courts are bound by decisions of superior courts (the Supreme Court) even where such adherence might work individual hardship. The case also confirms the proper application of the three-part test for issue estoppel derived from English law (Carl Zeiss Stiftung v Rayner & Keeler) as adopted in Zimbabwean jurisprudence. In the tax law context, it upholds the validity of assessments requiring payment in foreign currency where taxes are chargeable in foreign currency under the relevant legislation.
