  We report on the possibility of observing Higgs sector CP violation of the
minimal supersymmetric standard model at a hadron machine. The CP phase
dependent cross-sections for the $VH_i$ associated production processes are
given for the Fermilab Tevatron and CERN LHC. Substantial production
cross-sections for channels of all three Higgs bosons simultaneously are shown
to be possible, giving a drect indication of the CP violation. The
observability of the Higgs signals are discussed.
