The question of independent CP-violating phases is analyzed within the framework of left-right--symmetric SU(2)/sub R/ x SU(2)/sub R/ x U(1) gauge theories. Constraints on the cP-violating phases resulting from particular choices of symmetry breaking are discussed. Their implications for the CP-violation model suggested earlier by Mohapatra and Pati are noted. It is pointed out that in models with more than four quarks, the relation between the magnitudes of the CP-violating parameter eta/sub +/- and parity-violation parameter (M/sub W/ +- L/M/sub W/ +- R)/sup 2/ noted in the above paper can be maintained provided there is no mixing between heavier and lighter quarks. This leads to an island of stable and quasistable high-mass hadrons.
