The maximal CP violation hypothesis is applied to a simple lepton mixing matrix form U=V^\ifmmode†\else\textdagger\fiUTB, Vand UTB are the quark mixing matrix and the so-called tribimaximal mixing matrix, respectively, which has recently been speculated under an ansatz that U becomes an exact tribimaximal mixing UTB in the limit of the quark mixing matrix V\ensuremath→1. The prediction tan2\ensuremathθ12=1/2 in the case of the exact tribimaximal mixing U=UTB is considerably spoiled in the speculated mixing U=V^\ifmmode†\else\textdagger\fiUTB. However, the application of the hypothesis to the lepton sector can again recover the spoiled value to tan2\ensuremathθ12\ensuremath≃1/2 if the original Kobayashi-Maskawa phase convention for V is adopted.
