The constitutive relations of a spatially and temporally non-local linear medium are shown to be constrained by the structure of modern electromagnetic theory. A constraint reflecting this fact is derived by resorting to the Lorentz covariance of the Maxwell postulates as well as by using Occam's razor to arrive at a parsimonious description of general linear media.
