MAJORITY (Goldstone J):
1. On Constitutional Interpretation: Courts should be "astute not to lay down sweeping interpretations at this stage but should allow equality doctrine to develop slowly and, hopefully, surely. This is clearly an area where issues should be dealt with incrementally and on a case by case basis with special emphasis on the actual context in which each problem arises." (citing Prinsloo v Van der Linde)
2. On Dignity and Equality: The prohibition of unfair discrimination recognizes that "the purpose of our new constitutional and democratic order is the establishment of a society in which all human beings will be accorded equal dignity and respect regardless of their membership of particular groups." Dignity is "a notoriously elusive concept" that "cannot, by itself, bear the weight of s.15's task on its shoulders. It needs precision and elaboration."
3. On Non-Constitutional Remedies: The principle that constitutional issues should be avoided where possible does not apply where the only remedy available to challenge the vesting would require using the very statutory provisions being challenged as unconstitutional.
4. On the Purpose of Section 21: Beyond preventing collusion, section 21 serves the wider purpose of assisting trustees in complex determinations of property ownership where honest spouses may not have kept accurate records of their respective contributions to jointly acquired property.
5. Assumption of Good Faith: "In the consideration of the effect of section 21 one must assume that Masters and trustees will act reasonably and honestly and not wish to claim for insolvent estates that which solvent spouses are able to establish belongs to them."
MINORITY (O'Regan J):
1. On Marital Status as a Ground: Marital status is a ground analogous to those specified in section 8(2) because "it is a matter of significant importance to all individuals, closely related to human dignity and liberty. For most people, the decision to enter into a permanent personal relationship with another is a momentous and defining one."
2. On Historical Discrimination Based on Marital Status: Such discrimination historically occurred in two ways: (a) denying benefits to unmarried couples; (b) discriminating against married women based on assumptions about gender roles and household responsibilities, entrenching inequalities between men and women.
3. On the Invasiveness of Section 21: The South African Law Commission and the Cork Committee (UK) both concluded that automatic vesting provisions constitute "an unjustified interference with individual property rights" and "an anachronism" inconsistent with modern matrimonial property law concepts.
4. On Comparative Law: The absence of provisions equivalent to section 21 in the United Kingdom, Canada, Australia, New Zealand and (to a large extent) Germany "suggests that such provisions are not an essential component of insolvency law." Most jurisdictions rely on voidable transaction mechanisms with heightened scrutiny for transactions between spouses.
5. On Over-breadth and Under-inclusiveness: Section 21 "catches within its net all spouses of insolvents, even those spouses innocent of collusion, and even those whom the trustee and creditors accept to be innocent of collusion" while failing to "affect a range of people who may be in a similarly questionable relationship with the insolvent, such as other close family members, personal friends or business associates."
SACHS J (separate concurrence with minority):
1. On Stereotypes and Dignity: Section 21 is "manifestly patriarchal in origin" and "promotes a concept of marriage in which, independently of the living circumstances and careers of the spouses, their estates are merged." Its "underlying premise is that one business mind is at work within the marriage, not two. This stems from and reinforces a stereotypical view of the marriage relationship which, in the light of the new constitutional values, is demeaning to both spouses."
2. On Patterns of Disadvantage: "An oppressive hegemony associated with the grounds contemplated by section 8(2) may be constructed not only, or even mainly, by the grand exercise of naked power. It can also be established by the accumulation of a multiplicity of detailed, but interconnected, impositions, each of which, de-contextualised and on its own, might be so minor as to risk escaping immediate attention, especially by those not disadvantaged by them."
3. On Marriage and Constitutional Values: "Being trapped in a stereotyped and outdated view of marriage inhibits the capacity for self-realisation of the spouses, affects the quality of their relationship with each other as free and equal persons within the union, and encourages society to look at them not as 'a couple' made up of two persons with independent personalities and shared lives, but as 'a couple' in which each loses his or her individual existence."
4. On Contextual Analysis: Equality jurisprudence requires examining "the larger social, political and legal context" and searching "for disadvantage that exists apart from and independent of the particular legal distinction being challenged" to evaluate "how the legal underpinnings of social life reduce or enhance the self-worth of persons identified as belonging to such groups."
