We establish a Langrange multiplier rule, in terms of Clarke generalized gradient, that characterizes ϵ-efficiency of a nondifferentiable multiobjective programming problem on a real Banach space. This rule is then utilized to establish relationship between ϵ-efficient solution of multiobjective program and generalized saddle point of an appropriate vector-valued Lagrangian under invexity hypothesis.
