Abstract
The relativistic semi-classical approximation for a free massive parti cle is studied using the Wigner-Weyl formalism. A non-covariant Wiper function is proposed using the Newton-Wigner position operator. The pe rturbative solution for the time evolution is found. Causality is foun d to be perturbatively respected.
