A {mu}{sup +}{mu}{sup {minus}} collider is an appealing machine to probe resonant {ital CP}-violating transitions of a {ital CP}-even Higgs particle into the {ital Z} boson or into another {ital CP}-odd Higgs scalar. These phenomena are studied within a manifestly gauge-invariant approach implemented by the pinch technique. The {ital CP} invariance of an extended Higgs sector motivated by supersymmetric E{sub 6} models is assumed to be broken radiatively by the presence of heavy Majorana fermions. {ital CP} violation originating from Higgs-{ital Z} mixing is found to be very modest, whereas {ital CP}-number-violating transitions involving Higgs scalars only can be resonantly enhanced up to order of unity. {copyright} {ital 1996 The American Physical Society.}
