  We study the simplest Two-Higgs-Doublet Model that allows for CP
nonconservation, where it can be parametrized by only one parameter in the
Higgs potential. Different concepts of maximal CP-nonconservation in the
gauge-Higgs and the quark-Higgs (Yukawa) sectors are compared. Maximal CP
nonconservation in the gauge-Higgs sector does normally not lead to maximal CP
nonconservation in the Yukawa sector, and vice versa.
