  We present a new method to analyze upcoming results in the search for CP
violating neutrino oscillations. The CP violating amplitudes
$\mathcal{A}_{\alpha\beta}^{kj}$ provide parametrization independent
observables, which will be accessible by experiments soon. The strong
prediction of a unique $\mathcal{A}_{\alpha\beta}^{kj}$ (the Jarlskog
invariant) in case of the standard three neutrino model does not hold in models
with new physics beyond the Standard Model. Nevertheless there are still
correlations among the amplitudes depending on the specific model. Due to these
correlations it is possible to reject specific new physics models by
determining only 3 of the CP violating amplitudes.
