We use a new weak basis invariant approach to classify all the observablephases in any extension of the Standard Model (SM). We apply this formalism todetermine the invariant CP phases in a simplified version of the MinimalSupersymmetric SM with only three non-trivial flavour structures. We proposefour experimental measures to fix completely all the observable phases in themodel. After these phases have been determined from experiment, we are able tomake predictions on any other CP-violating observable in the theory, much inthe same way as in the Standard Model all CP-violation observables areproportional to the Jarlskog invariant.Comment: 25 pages, 12 figure
