Constitutional Court judgment: Adonisi and Others v Minister for Transport and Public Works, Western Cape and Others; Minister of Human Settlements and Another v Minister for Transport and Public Works, Western Cape and Others [2026] ZACC 29 (2 July 2026) (“Adonisi”)
Transactional Risk
Private-sector investment in state-owned land underpins many of South Africa’s largest infrastructure and property developments, from logistics hubs and renewable energy projects to mixed-use precincts and urban regeneration initiatives. The Constitutional Court’s recent decision in Adonisi, although arising from a dispute concerning affordable housing in Sea Point, has important implications for these transactions.
For the commercial property sector, the judgment fundamentally changes how investors, developers, financiers and public authorities should assess risk when dealing with state-owned land. Constitutional compliance has now become an intrinsic part of a commercial due diligence consideration.
The Judgment in Context
The dispute arose from the Western Cape Provincial Government’s decision to dispose of the Tafelberg property despite earlier consideration of the site for affordable housing. Although the sale ultimately failed, the Constitutional Court exercised its jurisdiction to clarify important principles governing the disposal of public land.
The Constitutional Court considered issues including the timing of public participation, compliance with the Government Immovable Asset Management Act No. 19 of 2007 (GIAMA), consultation between different spheres of government, and whether statutory planning and housing processes alone satisfy the State’s constitutional obligations.
While these questions arose in a public law context, the commercial implications are significant. The judgment broadens the matters that purchasers, developers, financiers and lenders alike should investigate before acquiring or financing state-owned land, reinforcing the fact that constitutional compliance forms part of commercial due diligence rather than an issue reserved for litigation.
Why This is Important
concerns the governance framework regulating the management and disposal of public land- a framework that supports many of South Africa’s major commercial developments.
Modern infrastructure projects depend on coordinated public assets and investment. Industrial parks require utility networks, logistics developments rely on transport infrastructure, renewable energy projects depend on transmission corridors, and mixed-use developments frequently require public investment in roads, water and electricity. Public-private partnerships similarly often involve the redevelopment or disposal of strategically located state-owned land.
Commercial viability is underpinned by legal certainty. Investors and financiers need confidence that government decisions affecting land have been lawfully made and are capable of withstanding judicial scrutiny. Where uncertainty exists, financing may be delayed, transaction costs may increase, project timelines may be disrupted, and investment decisions may be reconsidered.
Viewed in this context, Adonisi reinforces that sound governance of public land is not merely a constitutional imperative- it is also a prerequisite for investment certainty and successful project delivery.
A New Due Diligence Framework
Historically, due diligence for acquisitions of state-owned property focused on title, zoning, environmental approvals and statutory compliance. Following Adonisi, that approach is no longer sufficient.
Developers acquiring state-owned land, whether through public tender, negotiated disposal or public-private partnerships, should now consider whether meaningful public participation occurred before the disposal decision, whether the property was properly identified as surplus under GIAMA, whether the necessary intergovernmental consultation took place, and whether the land had previously been identified for affordable housing or another public purpose that could expose the transaction to constitutional challenge.
The judgment also has important financing implications. Constitutional litigation may delay or even unwind projects after commercial agreements have been concluded, affecting financial close, drawdowns, project timelines and the value or enforceability of security.
Transaction documentation may therefore require stronger contractual protections, including enhanced warranties regarding constitutional and statutory compliance, conditions precedent linked to the completion of public law processes, appropriately calibrated long-stop dates, and carefully drafted risk allocation mechanisms.
Banks and development finance institutions should likewise consider whether conventional property due diligence sufficiently addresses constitutional risk, particularly where security is taken over recently acquired state-owned land.
Implications for Public Authorities
For organs of state, the judgment confirms that statutory compliance alone will not necessarily satisfy constitutional requirements.
Public participation must be meaningful and appropriately timed. GIAMA processes must be properly documented, intergovernmental consultation obligations fulfilled where required, and decisions involving well-located public land must demonstrate that constitutional housing obligations have been properly considered before alternative uses are pursued.
The judgment therefore raises the governance standard applicable to future land disposals and reinforces the importance of transparent, well-documented decision-making capable of withstanding judicial scrutiny.
Conclusion
South Africa’s infrastructure pipeline increasingly depends on private capital being deployed through transactions involving state-owned land. Adonisi makes it clear that statutory compliance alone no longer provides sufficient commercial certainty. Constitutional considerations now form part of the legal framework within which these transactions must be structured, financed and implemented.
Investors, developers, lenders and public authorities alike now need to recognise that constitutional compliance is no longer merely a public law issue to be addressed if litigation arises.
