We reexamine the constraints implied by SN 1987A observations on the decay rate of a multi-MeV [nu][sub [tau]] decaying into the visible channel [nu][sub [tau]][r arrow][ital e][sup +][ital e[minus]][nu][sub [ital e]], if its lifetime is more than 10 sec. We discuss its implication for the minimal left-right symmetric model with the seesaw mechanism for neutrino masses.
