The hypothesis of a real Cabibbo-Kobayashi-Maskawa matrix has been considered and found to be disfavoured by present measurements even when neglecting results from CP violation in neutral kaon decay. The Best Linear Unbiased Estimator has been used as a statistical approach to compute the confidence level. This result agrees with most of the previous literature but contradicts statements reported in a recent paper.
