Abstract:

Institutional sustainability is assessed through financial stability, managerial efficiency, technological innovation, and strategic planning. While these factors are significant, they do not fully capture the foundational importance of legality in underpinning institutional endurance, legitimacy, and adaptability. Here, 'institutional sustainability' refers to an organisation's capacity to persist, fulfil its mandate, and maintain public trust over time. For the purposes of this article, 'internalisation of legal limits' is defined as the process by which institutions consciously embed constitutional, statutory, and administrative boundaries into their core operations, leadership practices, and organisational culture.

This article contends that sustainability is intrinsically linked to the internalisation of legal limits, understood as the deliberate integration of constitutional, statutory, and administrative boundaries into the core routines, culture, and decision-making processes of institutions. The real-world consequences of failing to embed legality are stark: for example, the suspension of several South African university councils in recent years, caused by allegations of maladministration and unlawful governance practices, illustrates how institutions that neglect legal boundaries risk crisis intervention, reputational damage, and public mistrust.

Legal limits are frequently misinterpreted as external controls triggered only by litigation or oversight. By contrast, sustainable institutions embed these boundaries within their governance systems, regarding legality as a proactive guiding principle that shapes leadership, accountability, and institutional culture. As an initial step, council members can begin internalising legal limits by collectively reviewing the relevant legal frameworks that govern their institution, establishing a standing agenda item on legal compliance for their meetings, and seeking regular briefings from legal advisors to better inform their governance decisions. Employing a mixed-methods approach, this article combines doctrinal legal analysis with comparative governance and international policy research to examine how legality, rationality, procedural fairness, and accountability function as structural conditions for sustainable institutional governance.

The article further asserts that institutional sustainability cannot be achieved solely through managerial reforms or policy initiatives. Sustainable institutions are governed by law, with constitutional and legal limits forming the foundation of governance principles. Embedding legality within governance, leadership, and organisational culture is essential for the long-term legitimacy, adaptability, and resilience of public institutions, including those in higher education. For example, consider a university senate meeting in which the academic board must decide whether to exclude students for academic underperformance. In a legally grounded institution, the board meticulously consults the university's enabling legislation and procedural rules before making a decision. Members pause to ensure that all affected students have received proper notice, been offered an opportunity to respond, and that the decision-making process aligns with constitutional fairness requirements. This conscious adherence to legal norms, even in routine matters, not only prevents future legal challenges but also promotes trust and integrity within the academic community.
