The Zimbabwe Stock Exchange v The Zimbabwe Revenue Authority

In May 2006, a dispute arose regarding the liability of stockbrokers to pay Value Added Tax (VAT). The Zimbabwe Stock Exchange brought an application seeking a declarator that stockbrokers are exempt from paying VAT in terms of section 11(a) of the Value Added Tax Act [Chapter 23:12] for services rendered in the normal course of their business. As a result of this dispute, stockbrokers ceased trading and the bourse came to a complete halt. Trading only resumed on 30 May 2006 when an agreement was reached between stockbrokers and government that accrued tax would not be collected pending court determination. The applicant (Zimbabwe Stock Exchange) itself was not a stockbroker and was not liable to pay VAT, but brought the application on behalf of stockbrokers. Stockbrokers were not members of the Zimbabwe Stock Exchange, nor were they joined as parties to the application.

• Whether the applicant had locus standi to bring the application on behalf of stockbrokers
• Whether stockbrokers are exempt from paying VAT under section 11(a) of the Value Added Tax Act
• Whether the application was opposed
• Whether the matter was lis pendens before another tribunal (the fiscal court)

The application was dismissed with costs awarded to the respondent.

In private interest litigation, an applicant seeking to bring an action on behalf of others must demonstrate: (1) a direct and substantial interest in the subject matter; (2) a legal interest (not merely a factual or commercial interest) in the subject matter; and (3) that such legal interest will be prejudicially affected by the court's decision. A general interest in the resolution of a dispute or sympathy with one party's position is insufficient to confer locus standi. The test for locus standi in private interest litigation is narrower and more stringent than in public interest litigation.

The court made several obiter observations: (1) A distinction should be made between public interest litigation (protecting public rights affecting large numbers of people) and private interest litigation (settling private disputes), with potentially different tests for locus standi applicable to each. (2) While the court is generally inclined to widen rather than constrict access to justice, this should not distort the time-tested principles that apply to private interest litigation. (3) The court left open the question of whether a requirement that the applicant's legal interest be prejudicially affected is necessary in public interest litigation. (4) The court noted that the Stock Exchange Act does not provide that the applicant can bring an action on behalf of stockbrokers. (5) The court observed that in cases where the Supreme Court took a "broad view" of locus standi, additional considerations were present, and affected parties were joined to the applications.

This case is significant in Zimbabwean jurisprudence for its comprehensive analysis of locus standi principles in private interest litigation as distinguished from public interest litigation. The judgment clarifies that in private interest litigation, a party seeking to bring an action on behalf of others must demonstrate a direct and substantial legal interest that will be prejudicially affected by the court's decision. The case reinforces that mere sympathy with a cause or general interest in an outcome is insufficient to confer standing. It also provides useful guidance on when courts will take a "broad view" of locus standi and distinguishes between different categories of litigation (constitutional applications under section 24, public interest litigation, and private interest litigation). The judgment serves as an important reminder that procedural requirements such as joinder of affected parties remain important even where courts are generally disposed to widening access to justice.
