  The laws of nature have come a long way since the time of Newton: quantum
mechanics and relativity have given us good reasons to take seriously the
possibility of laws which may be non-local, atemporal, `all-at-once,'
retrocausal, or in some other way not well-suited to the standard dynamical
time evolution paradigm. But many extant realist approaches to lawhood are
based on the paradigm of Newtonian laws, and thus they face significant
challenges when we try to apply them to laws outside the time evolution
picture. In light of these developments, we are in need of a new approach to
lawhood which is better suited for laws outside the time evolution paradigm. In
the present paper, we argue that this can be achieved within an approach which
conceptualizes lawhood in terms of modal structure, and we set out a general
framework in which the modal structure associated with a wide class of possible
laws can be expressed and studied.
