The effect of the nonequilibrium electron distribution functions in the superconductors on the properties of a tunneling junction is investigated. The state of nonequilibrium gives rise to a sharp increase in the effective temperature of the junction and an increase in the decay probability for the metastable current state. When the state of nonequilibrium is at a level higher than the threshold level, the effective temperature is negative. In this case phase and voltage oscillations arise in the junction at a current value lower than the critical value.
