The use and abuse of taxonomy

The late Professor Birks made an immense contribution to the study and development of the common law in devising his taxonomy, derived from the Roman classification of Justinian's Institutes. The utility of the taxonomy has always been the subject of controversy and its value has been increasingly questioned since his untimely death. Some of the criticisms are undoubtedly valid but it is seriously arguable that the pendulum has swung too far in the other direction. This paper seeks to highlight the common abuses of the taxonomy and demonstrate that, even taking account of its limitations, the taxonomy continues to be a useful device for our study and development of the common law.
