  In a more general electroweak theory, there could be Higgs particles that are
odd under $CP$. Correlations among momenta of the initial electron and
final-state fermions are in the Bjorken process sensitive to the $CP$ parity.
Monte Carlo data on the expected efficiency demonstrate that it should be
possible to verify the scalar character of an intermediate-mass Standard Model
Higgs boson after three years of data taking at a future linear collider. This
is most likely not possible at LEP2. Signals of possible presence of $CP$
violation in the Higgs sector are briefly discussed.
