  Recent CLEO results on the search for CP violation in decays of B and D
mesons and tau lepton are reviewed. New data on ``wrong-sign'' D decays and B
to K(*)l+l-$ FCNC transitions are presented. As possible Standard Model
contribution to many of studied processes is tiny, described efforts constitute
the search for physics beyond the Standard Model. Future CLEO-c efforts on the
subject are also outlined.
