Opinion per curiam.
The pivotal question before us is whether regulations of the Federal Communications Commission initially promulgated to facilitate the enactment of new copyright legislation can, once that purpose has been fully exploited, subsist without a fresh determination that they serve the public interest in some other manner. We answer that question in the negative.
I
After years of inconclusive effort to define a satisfactory relationship between broadcasting and cable 1 in the provision of television programming, 2 the Commission in 1971 issued a “Letter of Intent” 3 incorporating a “summary of the Commission’s proposals for the near-term regulation of cable television.” 4 This pronouncement adverted to a careful three-year revision of the Commission’s earlier cable policies, and declared that “[t]he policies put forward here result from an intensive study of the issues, balancing all the equities, and represent our best judgment on the regulatory course that should be followed.” 5 The letter of intent expressed the view that new copyright legislation was needed 6 in order to insure “the continued economic health of those who create program material,” a matter deemed “crucial to both broadcasting *975 and cable.” 7 The Commission felt, however, that cable regulation and copyright protection could be separately considered, 8 and “that copyright policy is most appropriately left to Congress and the courts.” 9 The Commission “note[d] the present efforts of the principals [in the controversy] to reach an agreement,” and “hope[d] that these efforts [would] be fruitful.” 10
Subsequently, the three major groups to be affected by the contemplated rules— broadcasters, cable operators and copyright owners — entered into a consensus agreement 11 proposing three modifications in regulations envisioned in the letter of intent with respect to cable carriage of television broadcast signals. 12 The Commission, in turn, “believe[d] that adoption of the consensus agreement [would] markedly serve the public interest.” 13 This belief was founded on the expectation that adoption of the proposed modifications would facilitate the passage of new copyright legislation and the realization of the benefits anticipated therefrom. 14 On this public-interest ground the Commission in 1972 chose the specifications of the consensus agreement in lieu of differing provisions of the letter of intent. 15 Late in 1976, *976 Congress revised the copyright laws extensively. 16
Meanwhile, in 1974, Henry Geller, the petitioner here, asked the Commission to reexamine portions of the cable television rules and to revamp them suitably, 17 in significant part by returning to particular regulatory provisions of the letter of intent that had been supplanted in the preference for the consensus agreement. 18 Prominent among Geller’s complaints were contentions “that the Commission’s 1972 cable television rules were in important respects not based on the Commission’s judgment as to what would best serve the public interest, but rather on the need to adhere to the “Consensus Agreement,” 19 and “that the Commission can no longer validly adhere to provisions that do not, in its judgment, best serve the public interest in view of ‘the undisputed fact that the agreement is now a dead letter.’ ” 20 These arguments did not impress the Commission however. While, stating that it was “open to proposals for changes in [its] cable television rules,” 21 and that “[additional changes in the rules [could] be anticipated in response to properly documented petitions for rulemaking or as part of [its] own continuing review of the rules,” 22 the Commission concluded that Geller’s petition did not “provide[] an appropriate vehicle for initiating further changes.” 23 Although it emphasized that past rulings clearly established that the consensus agreement interposed no barrier to modification of rules emanating from it, 24 the Commission perceived no occasion to reassess their validity on the basis of Geller’s petition:
It was the Commission’s judgment in 1972 that it would be in the overall public interest to adopt rules that closely followed the “Consensus Agreement” — that such rules not only served to protect the television broadcaster serving the public receivers but held forth the best prospect of fostering cable television growth within an appropriate and fair regulatory and legal context. The question for us now is whether all of the regulations adopted at that time remain justified. Although we are not prepared at this time to say they are contrary to the public interest, all of the rules are under review as part of our continuing re-regulation efforts. The petitions before us do not contain any evidence that aids us in making that judgment. We will, therefore, not institute the requested rulemaking proceedings at this time. Our overall review will continue, however, and we will remain receptive to properly documented suggestions for rule changes. 25
Then followed the petition for review now before us. 26
*977 II
[I] We are confronted at the threshold by a jurisdictional problem. In this court Geller contends for the first time that the Commission erred when in 1972 it translated the regulatory modifications urged in the consensus agreement into rules for the governance of cable television. Geller charges that in so doing the Commission baldly adopted the compromise reached by the three involved industries on the controversy long besetting cable television, without providing other segments of the interested public with any opportunity for input into the decision to be made. 27 Geller argues further, again for the first time, that the Commission’s acceptance of the industry compact could not have been justified by the supposed need to facilitate the passage of new copyright legislation. 28 Not only are these arguments inappropriate for judicial consideration in the first instance 29 but they are also grossly untimely. Direct review of Commission orders must be initiated within a period of 60 days; 30 here the interval between finality of the rulemaking order and the instant petition for judicial review was almost five years. 31 Resultantly, we lack jurisdiction to consider so much of Geller’s presentation. 32
It does not follow, however, that Geller is completely out of court, for his challenge to the continuing vitality of the Commission’s public-interest justification remains. The claim that the 1972 rule changes had fully served their stated purpose did not ripen until the new copyright legislation was enacted — just six weeks pri- or to the order denying Geller’s request for additional rulemaking. 33 Moreover, in *978 Functional Music, Inc. v. FCC, 34 we found jurisdiction to consider, in a proceeding not begun until late 1957, the validity of Commission regulations formulated in 1955. We explained:
As applied to rules and regulations, the statutory time limit restricting judicial review of Commission action is applicable only to cut off review directly from the order promulgating a rule. It does not foreclose subsequent examination of a rule where properly brought before this court for review of further Commission action applying it. For unlike ordinary adjudicatory orders, administrative rules and regulations are capable of continuing application; limiting the right of review of the underlying rule would effectively deny many parties ultimately affected by a rule an opportunity to question its validity. 35
Had the Commission applied one or more of the 1972 regulations to the detriment of some individual, he would clearly have been in a position to complain of the order doing so. Had Geller emulated Functional Music in an unsuccessful petition to eliminate specific regulations on demonstrable grounds of invalidity, his right to judicial review seemingly would be unquestionable. Although, in this case, Geller asked the Commission to commence a new rulemaking proceeding, 36 the same result must follow. Functional Music makes clear that the period statutorily prescribed for judicial review of an administrative order governs only direct review of that order. 37 Geller’s petition in this court is for review, not of the 1972 order promulgating the contested rules, but of the 1976 order refusing to reexamine their continuing validity. 38 To this extent, we have jurisdiction to entertain his complaint. 39
Ill
In denying Geller’s petition for new rule-making, the Commission stated, very accurately in our view, that “[t]he question for [decision was] whether all of the regulations *979 adopted [in 1972] remained] justified.” 40 Although the Commission was “not prepared at [that] time to say they [were] contrary to the public interest,” 41 it plainly was equally unprepared to say that the regulations were then consistent with the public interest. 42 Nonetheless, the Commission declined to conduct an inquiry in that regard because “[t]he petitions before [it did] not contain any evidence that aid[ed it] in making that judgment.” 43
Undeniably, an agency normally possesses a generous measure of discretion respecting the launching of rulemaking proceedings. 44 But though the discretion typically is broad, its exercise is reviewable if plainly misguided. 45 Already this court has twice applied that principle to vacate agency orders rejecting requests for rulemaking on the mistaken ground that the agency lacked jurisdiction to promulgate the regulations proposed. 46 And it goes without saying that the agency cannot sidestep a reexamination of particular regulations when abnormal circumstances make that course imperative. 47 That, we think, was the situation here. While the procedural vehicle Geller utilized was a petition for rulemaking, the far more important fact was that its allegations served to alert the Commission to the possibility that the regulations imported from the consensus agreement lacked a nexus with the public interest once the sought-after revision of the copyright laws was accomplished. 48
The relevant circumstances were rather clear to all. In 1972, the Commission had stated what from its viewpoint the public interest demanded in several aspects of cable television policy. 49 Some of the regulations that were to effectuate this public-interest determination were sacrificed to modifications proposed by the consensus agreement in a bid to facilitate the passage of copyright legislation. 50 From late 1976 onward, however, once that objective was achieved, 51 this rationale could no longer support the rules derived from the agreement. Yet the Commission, despite previous assurances to the contrary, 52 continues to adhere to the rules adopted on the basis of the consensus agreement — rules that it *980 has never found to serve the public interest in any other way.
What we have, then, are cable television rules that may or may not presently square with the public interest. Even assuming that the rules in question initially were justified by the aid the Commission expected them to afford to enactment of the copyright legislation — a question we do not decide 53 — it is plain that that justification has long since evaporated. The Commission’s general rulemaking power is expressly confined to promulgation of regulations that serve the public interest; 54 it “must place the public interest above private interests in carrying out its duties.” 55 And, as the Second Circuit has so well put it, “[t]he Commission may reach compromises, . . but it may not simply compromise between the interests of different broadcasting groups and gloss over the more fundamental public interest.” 56 Even a statute depending for its validity upon a premise extant at the time of enactment may become invalid if subsequently that predicate disappears. 57 It can hardly be supposed that the vitality of conditions forging the vital link between Commission regulations and the public interest is any less essential to their continuing operation. 58 We hold that the Commission is statutorily bound to determine whether that linkage now exists. 59
*981 The order under review is vacated, and the case is remanded to the Commission for further proceedings in light of the principles articulated herein.
So ordered.

Cable Television Report & Order,
. The modifications proposed in the consensus agreement dealt with television broadcast signal carriage, the subject of Part I of the Commission’s letter of intent. The suggested changes were described by the Commission as follows:
(i) Exclusivity. For syndicated programming, the agreement provides for extensive exclusivity in the top 50 markets, and more limited exclusivity in markets 51-100. For network programming, it substitutes simultaneous for same-day protection.
(ii) Local signals. The agreement changes the significant viewing standard applied to out-of-market independent stations in overlapping market situations from a one percent share of viewing hours to a two percent share; it does not alter the standard applied to network affiliates.
(iii) Leapfrogging. The agreement retains a UHF priority where a third distant signal is carried but changes the requirements for the first two signals. There is no restriction on these signals as to point of origin, except that if either is taken from any of the top 25 markets it must be from one of the two closest such markets. In the August 5 Letter these signals were, in effect, channels of independent programming (conceivably a blend of several distant stations); now they are restricted to specified distant stations except during exclusivity protection periods.
Id. at 166.
. Id.
. In its entirety, the Commission’s exposition on this score was as follows:
(i) First, the agreement will facilitate the passage of cable copyright legislation. It is essential that cable be brought within the television distribution market. There have been several attempts to do so, but all have foundered on the opposition of one or more of the three industries involved. It is for this reason that Congress and the Commission have long urged the parties to compromise their differences.
(ii) Passage of copyright legislation will in turn erase an uncertainty that now impairs cable’s ability to attract the capital investment needed for substantial growth. The development of the industry, at least with respect to assessing copyright costs, would be settled by the new copyright legislation and its future no longer tied to the outcome of pending litigation.
(iii) Finally, the enactment of cable copyright legislation by Congress — with the Commission’s program before it — would in effect reaffirm the Commission’s jurisdiction to carry out that program, including such important features as access to television facilities. It is important to emphasize that for full effectiveness the consensus agreement requires Congressional approval, not just that of the Commission. The rule will, of course, be put into effect promptly. Without Congressional validation, however, we would have to re-examine some aspects of the program. Congress, we believe, will share our conclusion that implementation of the agreement clearly serves the public interest.

Revision of Cable Television Rules Regarding Leapfrogging, Carriage of Local Independent Signals, and Non-Network Programming Exclusivity,

There remains the question of the effect of the consensus agreement on the Commission’s flexibility to shape cable’s evolution. Our judgment is, to repeat, that the agreement serves the public and should thus be reflected in the rules here adopted. The legislation that we believe must follow will limit the number of distant signals to which compulsory copyright licenses apply. In all other respects — for example, the details of network and syndicated programming exclusivity protection, leapfrogging, the significant viewing standard, the definition of signals that must be carried — the Commission retains full freedom and, indeed, the responsibility to act as future developments warrant.

E. g., Chastleton Corp. v. Sinclair,
. Compare WAIT Radio v. FCC, supra note 54, where, speaking of the occasional need for rule waivers, we admonished:
The Commission is charged with administration in the “public interest.” That an agency may discharge its responsibilities by promulgating rules of general application which, in the overall perspective, establish the “public interest” for a broad range of situations, does not relieve it of an obligation to seek out the “public interest” in particular, individualized cases. A general rule implies that a commission need not re-study the entire problem de novo and reconsider policy every time it receives an application for waiver of the rule. On the other hand, a general rule, deemed valid because its overall objectives are in the public interest, may not be in the “public interest” if extended to an applicant who proposes a new service that will not undermine the policy, served by the rule, that has been adjudged in the public interest.
. We do not mean to imply that this inquiry must necessarily be conducted in a new rule-making proceeding, as requested by Geller, so long as it is promptly pursued in some suitable manner. The Commission has made reference to ongoing investigations addressing segments of the challenged regulations,
