Thе petitions for review in this case arise out of an adjudicatory proceeding before the Nuclear Regulatory Commission (“NRC” or “Commission”) concerning proposed amendments to the license of Nuclear Fuel Services, Inc., a facility in Erwin, Tennessee (“NFS-Erwin”) that produces a special nuclear fuel used by the Navy. Petitioner Natural Resources Defense Council, Inc. (“NRDC”) requested a full adjudicatory hearing on the license amendments, as provided for in the NRC regulations at that time. In response, the Commission promulgated, without notice and comment, an immediately effective rule authorizing the use of alternative hearing procedures for matters involving “military and foreign affairs functions.” The Commission simultaneously issued an order granting NRDC’s hearing request but providing, under the new “military functions” rule, only a “legislative” type of hearing with limited procedural rights.
NRDC has petitioned for review of both the Commission’s adoption of the “military functions” rule and its simultaneous application of thе rule to the NFS-Erwin proceeding. NRDC contends that: (1) the “military functions” rule is invalid because it was initially promulgated without notice and comment; (2) the rule cannot be applied to the ongoing NFS-Erwin proceeding because it would substantially prejudice NRDC by eliminating its rights to, inter alia, cross-examination and discovery; and (3) the rule cannot properly be applied to *812 the NFS-Erwin proceeding because that proceeding does not involve “military or foreign affairs functions.” As explained in greater dеtail below, we conclude that none of these issues is properly before the court at this time. The first issue is now moot because the NRC has repromulgated the “military functions” rule in accordance with the notice and comment requirements of section 553 of the Administrative Procedure Act (“APA”), 5 U.S.C. § 553 (1976). The remaining two issues concern interlocutory actions by the Commission that are not yet subject to judicial review. Consequently, we dismiss the petitions so that the Commission may conclude the NFS-Erwin proсeedings and reach a final decision on the proposed license amendments.
I. HISTORY OF THE PROCEEDINGS
Operating under a license issued by the NRC, the NFS-Erwin facility produces a special, highly enriched uranium fuel that is used in the nuclear reactors that power Navy nuclear vessels. Historically, NFS-Erwin has had difficulty meeting certain requirements in its license and in the NRC regulations for maintaining control over and accounting for special nuclear material. See 10 C.F.R. § 70.51-.59 (1981). On more than one occasion the Commission has rеquired the facility to shut down in order that a reinventory of its special nuclear materials might be conducted. This case has its genesis in a 1979 shutdown and reinventory of NFS-Erwin stemming from the inability of officials at the facility to account for amounts of nuclear material in excess of the limits specified in its license. After conducting an inquiry into the problems at NFS-Erwin, the Commission issued an order on January 21, 1980, J.A. 24, 109-11, authorizing the facility to resume operations under revised physical security measures and material control and accounting requirements. The order also amended the NFS-Erwin license by relaxing its reinven-tory and shutdown requirements, thereby increasing the permissible amounts of “unaccounted for” nuclear material in the facility.
On February 6, 1980, petitioner NRDC requested a hearing on the proposed license amendments, as provided for in the Atomic Energy Act of 1954 1 and in the NRC regulations. J.A. 29-64. At that time, the Commission regulations provided for full hearing procedures that included discovery and cross-examination. See 10 C.F.R. § 2.740-.744 (1981). On Junе 26, 1980, however, the Commission promulgated, without notice and comment, an immediately effective rule allowing the agency to use alternative hearing procedures for matters involving “military and foreign affairs functions.” J.A. 178-89; 45 Fed.Reg. 45,-253 (July 3, 1980). 2 Essentially, the new rule incorporated the language of the “military and foreign affairs” exception to the formal adjudication requirements in the APA. 5 U.S.C. § 554(a)(4) (1976). 3 The Commission then issued an Order and a Notice of Hearing that granted NRDC’s hearing request but provided only a limited, “legislative” type hearing pursuant to the new “military functions” rule. J.A. 174-77, 190-93.
*813 NRDC filed two petitions for review in this court. The petition in No. 80-1864 challenged the adoption and application by NRC of the “military functions” rule on the grounds that (1) it was unlawfully promulgated without the notice and comment procedures required by the APA, 5 U.S.C. § 553 (1976), and (2) it could not lawfully be applied to the ongoing NFS-Erwin proceeding because it would substantially prejudice NRDC by eliminating its rights to, inter alia, cross-examination and discovery. The petition in No. 80-1863 challenged the NRC order invoking the “military functions” rule to limit the procedures available to NRDC in the NFS-Erwin proceeding on the ground that the proceeding did not involve “military or foreign affairs functions” within the meaning of both section 554 of the APA and the NRC rule. 4 On September 29, 1980, a motions panel of this court granted NRDC’s motion in No. 80-1864 for a stay of both the “military functions rule” and the order granting NRDC a limited hearing under that rule. 5
On September 30,1981, the NRC initiated informal rulemaking proceedings to reconsider the “military functions” rule and its application tо the NFS-Erwin proceeding. The Commission proposed a “military functions” rule that was essentially the same as the one it had previously issued. It asked for comments on whether the rule should be adopted in that form and on whether it should apply to ongoing proceedings in which a hearing already had been requested. 46 Fed.Reg. 47,799 (Sept. 30,1981). On January 26, 1982, the Commission adopted the “military functions” rule as proposed, with a section specifically making it applicable to ongoing proceеdings. Supp.J.A. 91-106; 47 Fed.Reg. 4490 (Feb. 1, 1982) (to be codified at 10 C.F.R. § 2700a). 6
This court postponed consideration of the case while the NRC conducted its rulemak-ing. 7 Now that the Commission has completed that rulemaking, the NRDC petitions for review are once again before the court. As hereafter explained, we conclude that considerations of mootness and finality prevent us from reaching the issues raised in those petitions.
II. MOOTNESS
NRDC continues to press its argument that the NRC promulgated its “military functions” rule in violаtion of the notice and comment requirements of section 553 of the APA. In light of the Commission’s repromulgation of the rule after providing notice and opportunity for comment, we conclude that this issue is now moot.
The “judicial Power” under Article III extends only to “Cases” and “Controversies.” U.S.Const. art. Ill, § 2. We therefore lack jurisdiction to pass upon a question in the absence of a “justiciable” controversy. The Supreme Court has made it clear that “no justiciable controversy is presеnted . . . when the parties are asking for an advisory opinion, [or] when the ques
*814
tion sought to be adjudicated has been mooted by subsequent developments .... ”
Flast v. Cohen,
NRDC has maintained that the promulgation by NRC of the “military functions” rule was unlawful because it deprived NRDC and other members of the public of the right to participate in the rulemaking process by not providing notice and an opportunity to comment on the rule. The Commission undeniably provided that opportunity, howеver, when it repromulgated the rule in accordance with the requirements of section 553 of the APA. Petitioner does not contend that there was any infirmity in the Commission’s repromulgation of the rule; rather, it continues to focus its attack on the initial adoption of the rule without notice and comment. Even if this attack was originally well-founded, we can hardly order the NRC at this point to do something that it has already done. As to this issue, NRDC
has obtained everything that it could recover ... by a judgment of this court in its fаvor. The duty of this court, as of every judicial tribunal, is limited to determining rights of persons or of property, which are actually controverted in the particular case before it. . . . But the court is not empowered to decide moot questions or abstract propositions, or to declare, for' the government of future cases, principles or rules of law which cannot affect the result as to the thing in issue in the case before it.

III. FINALITY
NRDC vigorously presses its arguments that the NRC cannot apply the new “military functions” rule in the NFS-Erwin proceeding because no military functions are involved and because applying it in that proceeding would substantially prejudice NRDC. Our jurisdiction to review the NRC actions, however, is limited. Section 189(b) of the Atomic Energy Act of 1954, 42 U.S.C. § 2239(b) (1976), provides only for judicial review of “[a]ny final order” entered by the NRC in any proceeding “for the granting, suspending, revoking, or amending of any license .. .. ”
Id.
§ 2239(a). Under the corresponding jurisdictional provision, 28 U.S.C. § 2342(4) (1976), the court of appeals has exclusive jurisdiction to review “all final orders of the Atomic Energy Commission [now the Nuclear Regulatory Commission] made reviewable by section 2239 of title 42 ....”
10
Consequently, even if the parties agree that the issues raised are properly before the court, these review provisions mandate a jurisdictional inquiry into the finality of the agency actions being challenged.
Citizens for a Safe Environment v. Atomic Energy Commission,
Courts exercising jurisdiction under 28 U.S.C. § 2342 have narrowly construed the term “final order.” An order is final if it “imposes an obligation, denies a right, or fixes some legal relationship, usually at the consummation of an administrative process.”
Honicker v. NRC,
Essentially, NRDC’s arguments challenge the decision of the Commission to limit the procedures available in the NFS-Erwin proceeding by invoking the “military functions” rule.
13
Ordinarily, however, “[a]n agency’s procedural or evidentiary rulings in the course bf a proceeding do not constitute a final order justifying judicial review except in extreme instances where the action is held to constitute an effective deprivation of appellant’s rights.”
Thermal Ecology Must Be Preserved v. Atomic Energy Commission,
Most importantly, the availability of relief on review of a final order in the license proceeding dictates against judicial review at this time.
E.g., Ecology Action,
Moreover, while deferring review until the NRC issues a final order entails á risk of requiring additional administrative proceedings, it nonetheless has significаnt practical advantages. First, it is possible
*817
that NRDC will obtain the relief it seeks from the agency, thereby avoiding judicial review entirely.
See Western Union International, Inc. v. FCC,
Similarly, the court will benefit from a more developed factual record in deciding whether the NFS-Erwin proceeding actually involves military functions. Indeed, it would be foolhardy for this court to reach out to decide this issue of virtual first impression on the basis of an incomplete factual record. 18 We are unpersuaded by NRDC’s contention that the hearing will produce little additional relevant information on the “military functions” question. In our view, the opposite result is more likely because the agеncy has every incentive to develop a sound factual record to support whatever final judgment it may reach in this case.
For the reasons set forth above, we conclude that the NRC determination that the NFS-Erwin proceeding involves “military functions” and its decision to limit the procedures in that adjudication pursuant to the “military functions” rule do not constitute final agency action that is subject to judicial review. 19
IV. CONCLUSION
NRDC’s contention that the “military functions” rule was invalidly promulgated has been mooted by the agency’s repromul-gation of the rule in accordance with the requirements of section 553 of the APA. *818 NRDC has also challenged the application of the rule by NRC to limit the procedures available in the NFS-Erwin proceeding. That decision, however, is not final agency action subject to judicial review. Consequently, we dismiss both petitions for review. 20
So ordered.
Notes
. Section 189 of the Atomic Energy Act of 1954 provides that
[i]n any proceeding under this chapter, for the granting, suspending, revoking, оr amending of any license . .. the Commission shall grant a hearing upon the request of any person whose interest may be affected by the proceeding.
42 U.S.C. § 2239(a) (1976).
. The new rule provided:
Consistent with due process requirements the Commission may provide alternative procedures in adjudications to the extent that there is involved the conduct of military or foreign affairs functions.
J.A. 182; 45 Fed.Reg. at 45,254.
. The relevant provision of the APA states:
(a) This section applies, according to the provisions thereof, in every case of adjudication required by statute to be determined on the record after opportunity for an agency hearing, except to the extent that there is involved—
(4) the conduct of military or foreign affairs functions....
5 U.S.C. § .554(a)(4) (1976).
. In the petition in No. 80-1863, NRDC also contended that the NRC order violated the hearing requirement in § 189(a) of the Atomic Energy Act, 42 U.S.C. § 2239(a) (1976). See note I supra.
. In No. 80 -1863, the motions panel held in abeyance as not yet ripe for decision NRDC’s motion for a stay and NRC’s motion to dismiss.
. The final rule provided:
(a) Consistent with 5 U.S.C. 554(a)(4) of the Administrative Procedure Act, the Commission may provide аlternative procedures in adjudications to the extent that there is involved the conduct of military or foreign affairs functions.
(b) This rule shall apply to proceedings in progress where hearings have already been requested or ordered as well as to future proceedings.
Supp.J.A. 106; 47 Fed.Reg. at 4493.
. The NRC notified the court on September 25, 1981 that it was reconsidering the “military functions” rule pursuant to notice and comment proceedings. After soliciting the parties’ views on whether this rulemaking rendered the case moot, the court issued an order on October 14, 1981 that postponed oral argument pending final action by the NRC in the rule-making, consolidated the petitions in Nos. 80-1864 and 80-1863, and ordered that the previously issued stay of September 29, 1980 remain in effect pending a final decision by the court. The records in both review proceedings were remanded to the NRC. to be returned after completion of the rulemaking.
. We recognize that, ordinarily, “ ‘voluntary cessation of allegedly illegal cоnduct does not deprive the tribunal of power to hear and determine the case,
i.e.,
does not make the case moot.’ ”
County of Los Angeles v. Davis,
Similarly, although there is an established exception to the mootness doctrine for cases “capable of repetition, yet evading review,”
Southern Pac. Terminal Co. v. ICC,
. Petitioner relies on
Dow Chem. Co. v. EPA,
. The Energy Reorganization Act of 1974, which transferred the licensing and related regulatory functions of the Atomic Energy Commission to the NRC, 42 U.S.C. § 5841(f) (1976), made the judicial review provisions of 28 U.S.C. § 2342 applicable to “[fjinal orders and actions" of the NRC. 42 U.S.C. § 5871(g).
. In
Port of Boston Marine Terminal Ass’n v. . Rederiaktiebolaget Transatlantic,
. For example, the court in
Ecology Action
noted that an order denying intervention is reviewable as a final order.
. The “military functions” rule, as repromul-gated by the NRC, does contain a provision specifically allowing the rule to be applied to ongoing proceedings. See note 6 supra. NRDC did not, however, file a new petition сhallenging this provision as facially invalid. Rather, aside from its “notice and comment” argument, NRDC’s challenge focuses on the NRC’s decision to apply the rule to the particular, ongoing proceeding in this case, a decision which is embodied in the agency’s June 26, 1980 Order and Notice of Hearing.
. The example given by the court in
Thermal Ecology
of an order constituting an effective deprivation of rights is an order denying intervention.
. The court in
Ecology Action
suggested a possible exception for rulings that are “so flagrantly wrong and demonstrably critical as to makе” reversal a virtual certainty if the petitioner were to lose at the administrative level.
. For the same reason, the “collateral order” exception to the finality rule does not apply.
See Community Broadcasting of Boston, Inc. v. FCC,
. NRDC does not contend that, as a matter of law, an agency can never apply new procedural rules in a pending proceeding. Such application is unlawful only if it would cause injury' or substantial prejudice.
See Pacific Molasses Co. v. FTC,
. There is another reason for declining to review the NRC conclusion that the NFS-Erwin proceeding involves military functions. Under the NRC “military functions” rule, any time a party requests a hearing in a license proceeding (or in any adjudication for that matter), the NRC must determine whether a military or foreign affairs function is involved. That determination will invariably be made at the outset of the adjudication, when the NRC selects the procedures to be used. If every such “military functions” determination were immediately ap-pealable, judicial review would generally be required twice whenever the NRC applied the rule: once to review the agency’s decision concerning military functions and once to review the agency’s final decision on the merits of the adjudication. Such a bifurcated system of judicial rеview conflicts with principles of judicial economy and with the finality requirement of 28 U.S.C. § 2342(4) (1976).
. We also conclude that these issues are not “ripe” for judicial review. The Supreme Court has stated that a determination of ripeness depends on the fitness of the issues for judicial review and the hardship to the parties of withholding court consideration.
Abbott Laboratories v. Gardner,
. In dismissing both petitions, we grant the NRC’s motion to dismiss No. 80-1863 for lack of jurisdiction. We also hereby dissolve the stay granted on September 29, 1980 and extended on October 14, 1981.
