THE NEW THINGS: PROPERTY RIGHTS IN DIGITAL FILES?

Published online by Cambridge University Press:  12 April 2022

Abstract

This paper looks at the property status of digital files, such as electronic documents, under English law. We argue that, while mere information is rightly not considered property, digital files are not mere information. Instead, they are distinct virtual objects that exist at the logical – or software – layer of a computer system. Property law could recognise digital files as a new, third kind of thing, alongside things in possession and in action. Doing so might help resolve disputes over access to digital files, by providing proprietary remedies similar to those available for paper documents.

64 See e.g. Bridge et al., Law of Personal Property, [8-016] noting that a “transfer in the law of property … immediately deprives the transferor of the thing transferred rather than potentially doing so over time depending on whether new information is written over the ‘deleted’ file”.

65 Cf. ibid., at [8-012] noting that digital copying can cause degradation of quality in case of errors, especially when large quantities of data are copied at the same time.

66 This analysis becomes more complicated where digital files are stored in the cloud and the cloud service user interface permits multiple users to access and edit the file at the same time, as with Google Docs or Office 365.

132 Although the server might still be fully functional, it could be argued that in obtaining unlawful access to B's server and deleting the file, Charles has reduced the server's usefulness to Bill, thereby damaging his property.

133 For a similar argument, see Fairfield, “Virtual Property”, 1081.

134 Admittedly, Alice might have alternative legal remedies against Charles, such as in tort law, as well as against D, such as a request to access personal data under data protection law or an order for delivery up of an infringing copy under copyright law. As discussed above, such alternative remedies would apply only in certain cases, such as when the file contains a protected work and Alice holds the relevant copyright. In any event, in our view, the availability of alternative remedies in some cases does not justify restricting the analysis under property law to the physical layer only.

151 In Elena Vorotyntseva v Money-4 Ltd. [2018] EWHC 2596 (Ch), the High Court issued a proprietary injunction preventing the removal of certain cryptocurrency holdings. The defendant had not disputed the property status of cryptocurrency and the court did not further discuss this issue. In Ion Science Ltd. v Persons Unknown and others (unreported), 21 December 2020 (Commercial Court), the High Court also applied a proprietary injunction to bitcoin. Butcher J. accepted that bitcoin were property, without determining the type of property involved. For cases from the Supreme Court of British Columbia, see Copytrack Pte Ltd. v Wall [2018] BCSC 1709 and Shair.Com Global Digital Services Ltd. v Arnold [2018] BCSC 1512. In both cases, the court applied proprietary remedies of preservation and recovery to cryptocurrencies, without explicit discussion of property rights.
