Remarks on a challenge to the relation between $CPT$ and Lorentz violation

Abstract

The objection [arXiv:1103.0168] to my theorem [arXiv:hep-ph/0201258] that violation of CPTCPT symmetry implies violation of Lorentz covariance is based on a nonlocal model in which time-ordered products are not well defined. I used covariance of time-ordered products as the condition for Lorentz covariance; therefore the proposed objection is not relevant to my result.
