R v Morris [1984]

R v Morris [1984] AC 320, also referred to as R v Morris; Anderton v Burnside, is a joined case heard by the House of Lords that dealt with the interpretation of appropriation in the context of theft, establishing essential principles that clarified the scope of this legal concept.

The defendants engaged in the deceptive practice of switching labels on supermarket goods to pay a lower price than the actual value of the items. The pivotal legal question revolved around whether such actions constituted dishonest appropriation.

The defence argued that appropriation required the assumption of all rights of the owner, and since the defendants only assumed some rights by manipulating the labels, it did not amount to appropriation. The concession made by the defence laid the foundation for a significant legal debate.

In delivering the judgment, Lord Roskill elucidated that appropriation entails an adverse interference with or usurpation not expressly or impliedly authorised by the owner. Crucially, he clarified that the prosecution need only prove the assumption of any of the owner's rights, not necessarily all of them.

Lord Roskill emphasised that appropriation could manifest through a single act or a combination of acts. In this case, the removal of items from shelves or the label-switching, viewed in isolation, did not constitute appropriation. However, it was the amalgamation of these acts that constituted appropriation, irrespective of the order and interval between them.

A notable aspect of Lord Roskill's judgment was the acknowledgment that the simultaneous assumption of some rights of the owner suffices for appropriation. This interpretation departed from the defence's contention that all rights needed to be assumed.

Despite its significance in clarifying the concept of appropriation, Lord Roskill's judgment was later subject to criticism and modification. Subsequent cases, such as R v Gomez [1993], challenged and refined certain aspects of Lord Roskill's reasoning. For instance, it was observed that the idea that appropriation involves an adverse interference with the owner's rights was no longer universally applicable, especially in cases involving a valid transfer of property, as established in R v Hinks [2000].

In conclusion, R v Morris played a crucial role in shaping the understanding of appropriation in theft cases, setting a precedent that appropriation could be constituted by a combination of acts involving the assumption of some rights of the owner, as opposed to the assumption of all rights.
