N2 - We present a necessary condition on the solar oscillation amplitude for CP violation to be detectable through neutrinoless double beta (0νββ decay. It depends only on the fractional uncertainty in the νe-νe element of the neutrino mass matrix. We demonstrate that even under very optimistic assumptions about the sensitivity of future experiments to the absolute neutrino mass scale, and on the precision with which nuclear matrix elements that contribute to 0ββ decay are calculable, it will be impossible to detect neutrino CP violation arising from Majorana phases.
