Uganda Commercial Court: Revisor Holds Copyright in Derivative Works; Unauthorized Publica

The Commercial Court of Uganda, in the case of Yusuf Kiwanda v Prof. Dr. George Wilson Kanyeihamba (Civil Suit No. 510 of 2021) [2026] UGCommC 526, ruled on October 29, 2026, that a reviser of an earlier work holds copyright in their original derivative contributions, and that unauthorised publication of such work infringes both copyright and moral rights.

This decision is profoundly significant for intellectual property law in Uganda, particularly for authors, publishers, and legal professionals dealing with derivative works. It clarifies and reinforces the principle that even when building upon existing material, a reviser's original creative input is independently protectable under copyright law. This encourages the creation of new editions, adaptations, and updates of works, while simultaneously providing robust protection against their unauthorised exploitation. For businesses, this ruling underscores the critical importance of securing explicit permissions and licenses for any revised or adapted content, as failure to do so can lead to liability for both economic and moral rights infringement.

The legal context for this ruling is primarily the Copyright and Neighbouring Rights Act of 2006, which governs intellectual property rights in Uganda. The Act defines what constitutes a copyrightable work, including derivative works, and outlines the economic rights (such as reproduction and distribution) and moral rights (such as the right of attribution and integrity) of authors. The Commercial Court, as a division of the High Court, is empowered to hear and determine commercial disputes, including those pertaining to intellectual property. Its pronouncements, like this one, serve as important precedents within the Ugandan legal system, guiding future interpretations and applications of copyright law, subject to potential appeals to higher courts.

The key parties involved in this specific litigation were Yusuf Kiwanda and Prof. Dr. George Wilson Kanyeihamba, whose dispute led to this clarification of copyright principles by the Commercial Court of Uganda. While the excerpt does not detail the specific roles of the parties or the full factual matrix of their disagreement, it establishes the legal principle that was at the heart of their case. The outcome of this specific matter beyond the stated legal principle is not reported in the excerpt.

Practitioners should advise clients, especially those in publishing, academia, and creative industries, to meticulously document all original contributions made to derivative works and to ensure that all contractual agreements clearly delineate ownership and licensing terms for such contributions. Businesses must conduct thorough due diligence and intellectual property audits before publishing or distributing any revised content to mitigate the risk of infringement claims. Furthermore, attorneys should be prepared to litigate or defend claims involving both economic and moral rights in derivative works, understanding that a reviser's original input is afforded distinct legal protection under Ugandan law.
