  It is commonly agreed that relativity requires that the descriptions of physical reality (i.e., the states of systems, their properties, dynamical laws, etc.) in different coordinate systems should be compatible with each other. In particular, descriptions of the state of systems in different foliations of spacetime into parallel spacelike hyperplanes, which correspond to different inertial reference frames, are to be related to each other by the Lorentz transformations. If this requirement is to reflect the structure of the Minkowski spacetime, these transformations must hold at the level of individual processes, and not only at the level of ensembles of processes (i.e., at the statistical level) or observed phenomena. Indeed, Bohm's theory, which is manifestly non-relativistic, satisfies the requirement that the Lorentz transformations obtain at the level of the observed phenomena.
