Newton's Third Law

Lisa Morris writes:
Are there limitations to Newton's Third Law and, if so, what are they?
In short, yes. Newton's third law (N3) ONLY applies in the non-relativistic
limit; it is, by definition, Newtonian. N3 is manifestly inconsistent with
interactions which are not propagated instantaneously across finite distances.
(Of Newton's laws, only his first one goes over unscathed into relativity.)
