As far as I know, anything going faster than the speed of causality violates causality. So what are you talking about?
But we don’t know that casualty is a law of physics, do we?
SR breaks down at both ends of the spectrum, at the event horizon of black holes and in Bose Einstein condensates. That proves that it is an emergent property of observations, statistical behavior of decoherent systems, and not a universal law.
