The effects of parity and time reversal violating potential, in particularthe tensor-pseudotensor electron nucleus interaction are studied. We establishthat selected terms representing the interplay of these effects and theresidual Coulomb interaction in the coupled-cluster method are equivalent tothe coupled perturbed Hartree-Fock. We have shown that the {\em normal} CPHFdiagrams have a one-one correspondance in the coupled-cluster theory, but theCPHF pseudo diagrams are present in a subtle way. We have studied the {\empseudo} diagrams in great detail and have shown explicitly their origin incoupled-cluster theory. This is demonstrated by considering the case of thepermanent electric dipole moment of atomic Hg and our results are compared withthe results of an earlier calculation.
