Fair rationing is essentially local: an argument for postcode prescribing.
In this paper I argue that resource allocation in publicly funded medical systems cannot be done using a purely substantive theory of justice, but must also involve procedural justice. I argue further that procedural justice requires institutions and that these must be "local" in a specific sense which I define. The argument rests on the informational constraints on any non-market method for allocating scarce resources among competing claims of need. However, I resist the identification of this normative account of local justice with the actual approach to local decision-making taken within the UK National Health Service. I illustrate my argument with reference to the case of provision of In Vitro Fertilisation within the UK NHS.
