that might occur by 2020 [^7], claim to have shown “once and for all that it is impossible to detect CP-violation from -decay in the foreseeable future.” We have strong doubts that it is possible to foresee with certainty all the scientific and technological developments relevant to the problem of interest, which will take place in the next $\sim (10 - 18)$ years. Correspondingly, the approach we follow in the present work is “orthogonal” to that adopted in [@BargerSNO2bb]: here we make an attempt to determine the conditions under which CP-violation might be detected from a measurement of and $m_{\bar{\nu}_e}$ (or $\Sigma$), or of and a sufficiently stringent upper limit on $m_1$ or $\Sigma$.

The Neutrino Mass and Oscillation Data and the Predictions for the Effective Majorana Mass 
===========================================================================================

1.0cm As we have seen, the predicted value of depends in the case of 3-neutrino mixing of interest on: i) the value of the lightest neutrino mass $m_1$, ii) $\Delta m^2_{\odot}$ and $\theta_{\odot}$, iii) ${\mbox{$\Delta  m^2_{\mathrm{atm}}$}}$, and iv) the lepton mixing angle $\theta$ which is limited by the CHOOZ and Palo Verde experiments [@CHOOZ; @PaloV]. Given the indicated parameters, the value of depends strongly on the type of the neutrino mass
