Instantaneous interactions violate causality only if you assume that
boost transformations are universal and independent on interactions.
In the previous thread "Lorentz transformations are not universal and
not exact" I explained that usually assumed universality of boost
transformations contradicts the Poincare group properties, and,
therefore, it contradicts the relativistic invariance. In a relativistically
invariant theory of interacting particles both time translations and
boosts must depend on interactions. In the version of QED I proposed in
yet another thread, the Coulomb and magnetic forces are instantaneous,
but due to the interaction dependence of boosts they are instantaneous
in ALL frames of reference. Therefore, the effect never precedes the cause.
