This comparison of United States v. Nixon and the Pentagon Papers case finds the greatest similarity and significance shared by the two cases was the anti-climactic nature of their conclusions. While both cases concerned constitutional questions of the highest order, centered around the scope of the executive power, both cases were drawn on such narrow grounds that there was hardly any effect on constitutional law doctrine.
