I concur in the denial of certiorari in this case, but solely out of considerations of timing. Questions of great importance to the Washington D.C., area are presented by the petition, not the least of which is whether the Court of appeals has, for a second time, unjustifiably frustrated the efforts of the Executive Branch to comply with the will of Congress as rather clearly expressed in § 23 of the Federal-Aid Highway Act of 1968, 82 Stat. 827. If we were to grant the writ, however, it would be almost a year before we could render a decision in the case. It seems preferable, therefore, that we stay our hand. In these circumstances Congress may, of course, take any further legislative action it deems necessary to make unmistakably clear its intentions with respect to the project, even to the point of limiting or prohibiting judicial review of its directives in this respect.
