1. Dagan uses the term ‘self-determination’ interchangeably with ‘autonomy’ and ‘self-authorship’ (41), so I shall use ‘self-determination’ except in cases of direct quotation where the other terms are used. I discuss the differences between Dagan’s notion of self-determination and Raz’s notion of autonomy in James Penner, “Taking Raz Seriously: On the Value of Autonomy and its Relation to Private Law” in Paul B Miller & John Oberdiek, eds, Oxford Studies in Private Law Theory: Volume 2 (Oxford University Press) [forthcoming in 2022].

See JE Penner, “Property” in Andrew S Gold etal, eds, The Oxford Handbook of the New Private Law (Oxford University Press, 2021) 277; JE Penner, “The (True) Nature of a Beneficiary’s Equitable Proprietary Interest Under a Trust” (2014) 27:2 Can JL & Jur 473 at 488-89; JE Penner, Property Rights: A Re-Examination (Oxford University Press, 2020) at 14 [Penner, Property Rights].

5. Irit Samet-Porat suggests (in personal correspondence) that Dagan may be working with an ordinary language definition of property, but if that means a layperson’s definition, I think a fair reading of the text suggests otherwise. Dagan is clearly addressing lawyers and legal theorists, not the lay public. The thought could be modified to suggest Dagan is working with the common definition of property as understood by lawyers and legal scholars, but the whole point of this paragraph is that there is no such common definition of property amongst lawyers, letalone property scholars.

6. Now extended to encompass the law of trusts: see Hanoch Dagan & Irit Samet-Porat, “The Beneficiary’s Ownership Rights in the Trust Res in a Liberal Property Regime” [unpublished, on file with the author]; Hanoch Dagan & Irit Samet-Porat, “Express Trust as the Missing Piece in the Property Jigsaw” in S Degeling, J Hudson & I Samet (eds), Philosophical Foundations of Express Trust (Oxford University Press, forthcoming 2022); Hanoch Dagan & Irit Samet-Porat, “What’s Wrong with Massively Discretionary Trusts?” Law Q Rev (forthcoming 2022).

7. More accurately, the right that non-owners exclude themselves.

8. Clear exceptions are Tom Merrill and Henry Smith. See e.g. Thomas W Merrill & Henry E Smith, “The Property/Contract Interface” (2001) 101:4 Colum L Rev 773. For what it is worth, I have dipped my toe in these waters; see James Penner, “Ownership, Co-ownership, and the Justification of Property Rights” in Timothy Endicott, Joshua Getzler & Edwin Peel, eds, Properties of Law: Essays in Honour of Jim Harris (Oxford University Press, 2006) 166. The one thing I failed to do in that piece was make clear that my social, ‘sharing’ model of co-ownership did not align with the positive law. The common law model of co-ownership is hardly one of sharing: see the text accompanying note 9, below.

11. See also Dagan & Heller, supra note 3 at 60-61, 96.

12. Dagan and Heller favourably compare the provisions of other jurisdictions to US law, but I think they would agree that none of the alternative regimes of rules give full effect to liberal community. See Dagan & Heller, supra note 9 at 613-22. Matthew Harding suggests (in personal correspondence) that a bit of the spirit of liberal community might be found in the Australian High Court’s judgment in The Trustees of the Property of John Daniel Cummins, A Bankrupt v Cummins, [2006] HCA 6 at paras 71-73. The court refused to apply the equitable purchase contribution presumed resulting trust rules to a married couple, favouring instead the idea that the relationship of marriage is one of equal sharing. Thus an equal ownership, plus the right of survivorship, i.e. a joint tenancy, was presumed.

16. I have also recently argued that essential to understanding the nature of property rights is to make sense of the concept of ‘title,’ and I have argued that with respect to tangible property title has a tripartite structure, consisting of a right, the right to immediate exclusive possession, plus two powers, a power to license what would otherwise be a trespass and a power to transfer title to another. See Penner, Property Rights, supra note 4 at ch 1.

17. See e.g. JE Penner, The Idea of Property in Law (Clarendon Press, 1997) at 74-75.

18. I thank Andrew Simester and Irit Samet-Porat for pressing me on the points I make concerning this example.

19. For an illuminating discussion see Leslie Green, “Sexuality, Authenticity, and Modernity” (1995) 8:1 Can JL & Jur 67.

20. ‘Expressing one’s race’ is a much more problematic idea.

21. By which I mean things like holding hands, or hugging, or discussing their wedding plans, which display the bigot would not find objectionable if done by a heterosexual couple.

22. In extreme cases what he does can amount to a denial of that person’s very humanity, which is a distinct wrong, and one which can lead to horrific wrongs, some of which may count as injustices. For the difference between a denial of humanity and an injustice, see JE Penner, “Property, Community, and the Problem of Distributive Justice” (2009) 10:1 Theor Inq L 193 at 205, n 22; PMS Hacker, The Moral Powers: A Study of Human Nature (Wiley Blackwell, 2021) at 53.

23. And for an instrumentalist of my ilk, one of the important considerations that would have to be considered before proscribing in law this sort of discrimination would be whatever knock-on effects that it would have; it might, for example, lead to more bigotry, some responding to the proscription as a violation of their freedom of speech. Irit Samet-Porat (in private correspondence) astutely raises a corollary of my position, which is roughly that where the conditions of widespread discrimination no longer obtain, the relevant anti-discrimination law should be abolished. So, for example, where the humanity and dignity of gay people is widely respected, and their self-determination cannot really be said to be in any significant way thwarted by a few remaining bigots, should the law depart from the scene? I would say ‘yes,’ subject to a couple of ‘empirical’ caveats. If the abolition of the law would in fact lead to the status quo ante the legislation, and bigoted behaviour would once again become widespread, then of course the law must not be abolished. Secondly, for some (many?) people the law has a symbolic value, and having such a law in place would be symbolic of our society’s commitment to human dignity, so should be retained even if now, thank heavens, the law is desuetudinous. This consideration opens up a huge can of worms, since it is not at all clear that people should accord the law significant, or indeed any, symbolic value. In a genuinely free and flourishing society I think the starting point should be to accord it none whatsoever. For an interesting discussion on a related issue, see Simon Keller, The Limits of Loyalty (Cambridge University Press, 2007) at chs 3, 4, 8.

24. This treatment of the issue draws upon Ripstein’s consideration of the same issue. See Ripstein, supra note 13 at 80, 82-86.

25. Dagan pursues this sort of example further at 133-35, but I don’t think anything he says there detracts from what I have said. Dagan does say that he sees no difference between the “uneducated bigot and the misguided but sincere religious believer” for his treatment of the issue. I do, but as the example I am discussing concerns bigots and Dagan distinguishes the two (though does not find the distinction relevant for his purposes), I shall not pursue the matter here. But see further the text accompanying note 36, below.

28. The situation is obviously more complicated with respect to workplace relationships. On one side we have Gardner, for whom occupations and the meanings they generate for people are first and foremost governed by social, cultural norms. These the law can either support or undermine. A significant undermining, he feels, is going on right now, under the spectre of what he calls ‘contractualisation’; see John Gardner, “The Contractualisation of Labour Law” in Hugh Collins, Gillian Lester & Virginia Mantouvalou, eds, Philosophical Foundations of Labour Law (Oxford University Press, 2018) 33. Dagan has replied, arguing roughly that a non-independence, self-realisation account of contract would not undermine the important social and cultural aspects of employment relationships; see Hanoch Dagan, “The Liberal Promise of Contract” in Haris Psarras & Sandy Steel, eds, Private Law and Practical Reason: Essays on John Gardner’s Private Law Theory (Oxford University Press) [forthcoming]. I shall not adjudicate the dispute here.

36. Of course this case is a very special one, and the principle would not cover most of what we understand to be anti-discrimination law, as Ripstein emphasizes in Ripstein, supra note 13 at 83-85. In particular it would not cover unintentional discrimination (83-84), as where an employer sets up a work schedule which inhibits the religious observances of its employees; it would also require Dagan to distinguish the case of the bigot from the sincere religious believer (see supra note 25).

51. I am not here denying that there is a conceivable regime of rights to resources under which no one has any exclusive rights, and that if such regime were in place poverty would ipso facto be eradicated. But since Dagan’s view is that, suitably adjusted, a liberal property regime can be justified, that needn’t be gone into here.
