During fiscal year 1973, President Nixon ordered the impoundment of about 18 billion dollars in Federal funds for domestic programs. A large portion of that amount was used to slash federal funding for education programs. The entire impoundment controversy revolves around the doctrine of separation of powers. Insofar as the President has refused to spend funds appropriated by Congress, he has acted unlawfully, in violation of the legislation which directs how the appropriations are to be spent. He has also acted unconstitutionally, in violation of his obligation to faithfully execute the laws passed by Congress. (Author/JF)
