"In this case, there is no indication that Congress sought to prohibit judicial review and there is most certainly no 'showing of "clear and convincing evidence" of a ... legislative intent' to restrict access to judicial review. Abbott Laboratories v. Gardner, 387 U. S. 136, 141 (1967)....
"Similarly, the Secretary's decision here does not fall within the exception for action 'committed to agency discretion.' This is a very narrow exception.... The legislative history of the Administrative Procedure Act indicates that it is applicable in those rare instances where 'statutes are drawn in such broad terms that in a given case there is no law to apply.' S. Rep. No. 752, 79th Cong., 1st Sess., 26 (1945)." Overton Park, supra, at 410 (footnote omitted).
The above quote answers several of the questions raised by the language of § 701(a), although it raises others. First, it clearly separates the exception provided by § (a)(1) from the § (a)(2) exception. The former applies when Congress has expressed an intent to preclude judicial review. The latter applies in different circumstances; even where Congress has not affirmatively precluded review, review is not to be had if the statute is drawn so that a court would have no meaningful standard against which to judge the agency's exercise of discretion. In such a case, the statute ("law") can be taken to have "committed" the decisionmaking to the agency's judgment absolutely. This construction avoids conflict with the "abuse of discretion" standard of review in § 706—if no judicially manageable standards are available for judging how and when an agency should exercise its discretion, then it is impossible to evaluate agency action for "abuse of discretion." In addition, this construction satisfies the principle of statutory construction mentioned earlier, by identifying a separate class of cases to which § 701(a)(2) applies.
To this point our analysis does not differ significantly from that of the Court of Appeals. That court purported to apply
