The idea that it should be possible to capture legislative rules as code and that good things might result from doing so is not a new one. It sounds as though it should be simple: the re-expression of what has already been captured in one structured language in another. It turns out though not to be at all simple, partly because of what John Sheridan calls the intertwingling of law: the idea that law often takes effect through reference and amendment and that the precise effect of its doing so can be hard to discern.
There is interesting work going on in New Zealand experimenting with the idea of law and code in some limited domains, and this post is prompted by that work. What makes it distinctive is that it is written from a policy perspective, asking questions such as whether the discipline of producing machine consumable rules is a route to better policy development. It’s still unclear how far this approach might take us – but the developments in New Zealand are definitely worth keeping an eye on.
