By use of unitarity of the Kobayashi-Maskawa matrix, the rephasing-invariant measure delta/sub KM/ of CP nonconservation is evaluated in terms of the modulus squared of four matrix elements, which are taken as the four independent parameters. The striking feature of such a formulation is that the positivity of delta/sub KM//sup 2/ gives both upper and lower bounds on the matrix elements chemically bondV/sub c//sub d/chemically bond, chemically bondV/sub c//sub s/chemically bond, chemically bondV/sub t//sub d/chemically bond, and chemically bondV/sub t//sub s/chemically bond.
