Several methods proposed to measure the anglein the KM unitarity triangle assumed that the tree contribution tois purely due to annihilation contributions and is negligibly small. This assumption has to be tested in order to have a correct interpretation of the experimental data. In this paper we show that using SU(3) symmetry, the smallness of the tree contribution can be tested in a dynamic model-independent way. We also derive several relations betweenCPviolating rate differences fordecays without assuming the smallness of the annihilation contributions. These relations provide important tests for the standard model ofCPviolation.
