Observing CP violating MSSM Higgs bosons at hadron colliders?

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 VHi 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 direct indication of the CP violation. The observability of the Higgs signals are discussed.
