For current purposes, the facts in the case are far less important than the result. While the disputes, misunderstandings and accusations between the parties gave rise to enough issues for the judge to fill an entire law exam, it need only be understood as a dispute about the ownership and handling of an amount of bitcoin.
The key question the learned judge had to answer, therefore, was whether the common law as applied in Australia should recognise bitcoin as personal property.
As we have explained in a previous briefing, there is now an increasing number of cases, across a range of common law jurisdictions, that have had to deal with this question. In broad terms (and as the Law Commission recognised in its Final Report), there is an emerging and deep consensus that crypto-tokens and similar digital assets are capable of being the objects of personal property rights.
However, the way in which judges reach that answer has not been wholly consistent. Specifically, they have had to grapple with the long-held principle that the common law recognises only two types of personal property:
- choses (things) in possession; and
- choses (things) in action.
This has required a decision to be made as to which of these categories relevant digital assets belong or whether a new "third category" of personal property should now be recognised to accommodate them. As intangible property that are not capable of being possessed, digital assets cannot be things in possession (as expressly recognised by Attiwill J).
Some judges have described their struggle to recognise crypto-tokens as things in action, because of a view that this can only refer to rights enforceable against a person or persons by legal action or proceedings – a limited conception of a "thing in action" that does not generally apply to crypto-tokens. In some cases, the judges (especially at interlocutory stages) have largely avoided reaching a view on the issue. The Law Commission has, however, thrown its weight behind the "third category" approach.
Re Blockchain is exceptionally helpful in its review and approval of the relevant cases and academic commentaries across Singapore, New Zealand, and England and Wales, as well as Australia. After doing so, it reaches a decisive conclusion (our emphasis added):
"As a result, I find that a person’s interest in Bitcoin is property. It is not a chose in possession as it is intangible. It cannot be possessed. It is a chose in action. As I have already said, it is well established in Australia that a chose in action comprises a heterogeneous group of rights which have only one common characteristic in that they do not confer the present possession of a tangible object. That is the case with Bitcoin."
Aligning Australian jurisprudence to that of Singapore and New Zealand, Attiwill J has concluded that bitcoin is capable of being personal property, and it is so because it is a thing in action.
We are unsurprised by this conclusion.
Apart from its consistency with the Singapore and New Zealand positions, another distinguished Australian judge in the digital assets space, Jackman J, has made two important interventions in the debate in 2024. He delivered a speech in June 2024 entitled 'Is Cryptocurrency Property?', in which he also surveyed the common law cases, as well as academic and juristic commentaries (including those under English law). He returned to the topic in his United Nations Day Lecture in October 2024, 'What Has Taxonomy Ever Done for Us?'
Directly considering the Bill, he very firmly reached the same conclusion as Re Blockchain and expressed the view:
"[T]he bill seeks to impose on the common law what I will seek to show is a misconception as to the nature of choses in action which, if it is enacted, will stultify the proper development of the common law. In short, the proposal is based on a remarkably ill-informed understanding of the common law in this area."
Importantly, he grounded his conclusion in what he referred to as Cain's Case, a 1954 decision of the High Court of Australia (Australia's highest court), which (as he compellingly outlined) is already binding authority for the proposition that things in action are not limited to rights which can only be enforced in legal proceedings.
Once that principle is accepted, two consequences follow entirely naturally:
- Cryptocurrency can be a thing in action.
- As a thing in action, it is capable of being the object of personal property rights.
