The prediction of vanishing reactor angle was thought to be a signature of 2-3 symmetry of neutrino mass matrix. But the present study addresses certain interesting facts related with 2-3 symmetry which are not addressed so far. The investigation highlights that θ₁₃=0, corresponds to a very special case in association with 2-3 symmetry and to engender a non-zero θ₁₃, the breakdown of 2-3 symmetry is not essential.
