A sufficient condition for optimality, involving a solution to the HamiltonJacobi equation, is well known. We provide here a modification of such a condition. This is expressed in terms of a sequence of locally Lipschitz-continuous functions which are extended solutions of the Hamilton-Jacobi equation. The condition is necessary as well as sufficient for optimality for a large class of problems, including nonnormal ones. The optimality condition admits simple constructive proofs in contrast to earlier, related conditions.
