The Pragmatic Sanction of Materials: Notes for an Ethnography of Legal Substances.

How is the law bound to the material world? This article examines the production of reference materials, artefacts that incarnate legally relevant measurements and serve as a transitional object for the law in its approximation to the stuff of the world. The argument, an opening for an ethnographic investigation into the life of legal materials, is based on a study of the work conducted at the Institute for Reference Materials and Measurements (IRMM), an agency that, for over fifty years, has fabricated official versions of the objects and substances mentioned in European law.
