OPINION OF THE COURT
The Secretary of Labor (“Secretary”) petitions for review of a final order of the Occupational Safety and Health Review Commission (“Commission”). The Commission’s order affirmed the order of an Administrative Law Judge (“ALJ”) vacat
I.
In December 2003, a representative of the Occupational Safety and Health Administration (“OSHA”) inspected the Charles Harwood Medical Complex project, one of Roy’s Construction’s work sites in the Virgin Islands. As a result of this inspection, on April 15, 2004 OSHA mailed citations to Roy’s alleging violations of OSHA safety standards at the site and proposing total penalties of $40,600.00. On April 17, someone signed for the citations on Roy’s behalf; a Roy’s office administrator later testified before the ALJ that the signer was not a Roy’s employee but rather an employee of a private mail company used by Roy’s. Under Section 10(a) of the Occupational Safety and Health Act of 1970 (“OSH Act”), an employer has fifteen working days from receipt of a citation and assessment of penalty to notify the Secretary of its intent to contest them. 29 U.S.C. § 659(a) (2000). If the employer has not provided such notice within fifteen working days, the proposed citation and assessment “shall be deemed a final order of the Commission and not subject to review by any court or agency.” Id. Roy’s did not notify OSHA of its intent to contest the citations within the statutory fifteen-working-day period, which expired on May 7, 2004. Accordingly, in June 2004 OSHA sent a letter to Roy’s requesting payment of the penalties plus interest. Roy’s attempted to reopen discussion of the citations with OSHA by telephone and eventually received a reply that the citations were final and that the only recourse available was an appeal to the Commission. In August 2004, OSHA sent a debt collection letter to Roy’s. Subsequently, Roy’s sent letters to OSHA (on August 17) and the Commission (on August 23) announcing its intent to contest the citations.
The Secretary moved before the Commission’s ALJ to dismiss Roy’s challenge to the citations as untimely. After holding an evidentiary hearing on April 13, 2005, the ALJ issued a Decision and Order on July 5, 2005 denying the Secretary’s motion to dismiss. The ALJ invoked Federal Rule of Civil Procedure 60(b), which states that a court may relieve a party from a final judgment or order resulting from,
inter alia,
“excusable neglect.”

See
Rule 60(b)(1). In
George Harms Construction Co. v. Chao,
Instead of filing a complaint, the Secretary sent a letter to the ALJ on August 24, 2005, informing him that “the Secretary hereby declines to file a Complaint to proceed on the merits because the Secretary believes that Your Honor’s decision to allow defendant’s [sic ] to file a late notice of contest was clearly erroneous.” The Secretary explained that her decision was intended “to preserve her right to appeal” and “is not characterized by bad faith, nor is it intended to prejudice the respondent in this case.” The ALJ responded on September 8, 2005 by ordering the Secretary to show cause “why the contested citation) should not be vacated for failure to file a complaint.” On September 16, the Secretary informed the ALJ again by letter that she would not file a complaint because she sought to “put this matter in a posture suitable for appeal.” Consequently, on October 13 the ALJ vacated the citations. 4 On November 1, the Secretary petitioned the full Commission for discretionary review of the ALJ’s decision granting Rule 60(b)(1) relief to Roy’s and his subsequent order vacating the citations. In her petition, the Secretary acknowledged that if the Commission ruled in Roy’s favor regarding the propriety of Rule 60(b)(1) relief, the ALJ’s vacatur order would stand and the Secretary would be precluded from litigating the citations on the merits.
The Commission issued its decision on June 1, 2006. Noting that ALJs have discretion under Commission Rule 101(a), 29 C.F.R. § 2200.101(a), to rule against “any party [who] has failed to plead or otherwise proceed as provided by these rules or as required by the Commission or Judge,” the Commission found that the ALJ had not abused his discretion by vacating the citations.
See Sec’y of Labor v.
The Secretary has filed a petition with this Court, asking us to review the Commission’s decision not to reach the merits of the Rule 60(b)(1) claim and to reverse the ALJ’s grant of Rule 60(b)(1) relief. We have jurisdiction under 29 U.S.C. § 660(b) (2000), which allows “[a]ny person adversely affected or aggrieved by an order of the Commission” to obtain review “in any United States court of appeals for the circuit in which the violation is alleged to have occurred or where the employer has its principal office.” The Secretary’s petition presents two questions: 1) whether the Commission erred by affirming the ALJ’s vacatur order solely on the ground that the Secretary failed to file a complaint, without reviewing the Secretary’s argument that the ALJ improperly excused Roy’s untimely NOC; 2) if we rule in the Secretary’s favor on the first issue, whether Roy’s filed its motion to excuse the untimeliness of its NOC “within a reasonable time” as required by Rule 60(b). Because we rule against the Secretary on the first issue, we need not reach the second question.
II.
Before addressing the Secretary’s contention that the Commission erred in its decision, we must address Roy’s arguments that the Secretary is barred from attacking the ALJ’s vacatur order at all. We find these arguments to be without merit.
First, Roy’s argues that the Secretary is barred from attacking the vacatur order as an unwarranted sanction because she did not raise this issue before the Commission. Our reading of the Secretary’s Brief before the Commission indicates otherwise. The Secretary’s Brief argued that the ALJ’s vacatur order should be reversed, that the Commission should not treat the order as a sanction for misconduct, and that the order is reversible even though the ALJ “appropriately entered it” at the Secretary’s request.
See
Opening Brief of the Secretary at 23-27,
Sec’y of Labor v. Roy’s Constr., Inc.,
Second, Roy’s contends that the Secretary is “judicially estopped” from arguing that the ALJ’s vacatur order was “in any manner improper” because she made the allegedly inconsistent argument before the Commission that she had actively solicited the order. We reject Roy’s contention because we do not view the Secretary’s arguments as inconsistent. The Secretary’s position all along has been that she sought the vacatur order solely as a means to obtain immediate review of the ALJ’s Rule 60(b) decision. She has never taken the position that the order was justified as a sanction for any alleged misconduct, and she has always made clear that her ultimate goal was to obtain a reversal of the order. Moreover, even if we believed that the Secretary’s positions have been inconsistent, we would not exercise our discretion to apply judicial estoppel because
Finally, Roy’s claims that if we reach the merits of the ALJ’s July 5, 2005 decision without setting aside the ALJ’s October 13, 2005 vacatur order, we would be rendering an advisory opinion. Roy’s argues further that we should not set aside the vacatur order because the Secretary is foreclosed from challenging it and because it is based on grounds independent from the July 5 decision. We have already rejected Roy’s arguments that the Secretary is foreclosed from challenging the vacatur order. As for Roy’s contention that we should not set aside the vacatur order because it stands on independent grounds, this is essentially a restatement of the Commission’s reasoning for affirming the vacatur order without considering the July 5 order. Accordingly, our discussion of the Commission’s decision in the next section will address this argument.
III.
Under Section 706 of the Administrative Procedure Act (“APA”), 5 U.S.C. § 706 (2000), a reviewing court shall set aside agency action that is “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.” We apply this standard to our review of the Commission’s decision. The Secretary presents two arguments in support of her contention that the Commission acted in an arbitrary and capricious manner by affirming the ALJ’s vacatur order without reviewing the ALJ’s earlier Rule 60(b) decision. First, she contends that the Commission’s action arbitrarily and capriciously flouted the federal “merger rule,” which provides that “interlocutory” orders issued before a final judgment are reviewable at the same time as the final judgment. By reviewing the ALJ’s final order vacating the citations without reviewing the interlocutory Rule 60(b) order, the Secretary argues, the Commission departed from the merger rule without a reasoned explanation. Second, she contends that the Commission arbitrarily and capriciously departed from its previous practice of allowing the Secretary to obtain immediate review of an order by refusing to proceed and thereby inducing the ALJ to issue a final appealable order.
A.
The Secretary’s first argument is that the Commission’s action arbitrarily
Whether Bethel and similar cases are distinguishable is beside the point, however, because nothing compels the Commission to follow federal merger rule precedents in the first place. The federal statute governing Commission procedure states simply: “The Commission is authorized to make such rules as are necessary for the orderly transaction of its proceedings. Unless the Commission has adopted a different rule, its proceedings shall be in accordance with the Federal Rules of Civil Procedure.” 29 U.S.C. § 661(g) (2000). Similarly, Commission Rule 2(b) provides: “In the absence of a specific provision, procedure shall be in accordance with the Federal Rules of Civil Procedure.” 29 C.F.R. § 2200.2(b) (2007). Nothing in the Commission Rules specifically addresses the merger rule, but the Federal Rules of Civil Procedure are also silent about it. Thus, we conclude that the Commission may depart from federal merger rule case law in its adjudications.
The Commission is more tolerant of interlocutory appeals than the federal court system. Under Commission Rule 73, the Commission has discretion to grant a petition for immediate interlocutory review of an ALJ’s ruling if it “involves an important question of law or policy about which there is substantial ground for difference of opinion” and immediate review “may materially expedite the final disposition of the proceedings,” or if the challenged ruling might result in the release of allegedly privileged information. 29 C.F.R. § 2200.73 (2007). The only comparable provision for interlocutory appeals in federal courts is 28 U.S.C. § 1292(b), which permits an appellate court to grant immediate interlocutory review when a district judge states in writing that an interlocutory order “involves a controlling question of law as to which there is substantial ground for difference of opinion and that an immediate appeal from the order may materially advance the ultimate termination of the litigation.... ” See 28 U.S.C. § 1292(b) (2000). Although much of the language of § 1292(b) is similar to that of Commission Rule 73, the two provisions differ significantly because § 1292(b) allows an appellate court to grant interlocutory review only when a district judge grants permission, whereas Commission Rule 73 allows the Commission to grant interlocutory review without an ALJ’s permission. In light of its greater discretion to hear interlocutory appeals, the Commission could reasonably conclude that the merger rule should have less force in appeals of an ALJ’s final judgments, at least when those final judgments are directed against a party that refused to proceed and made no attempt to seek interlocutory review. 9 Thus, Commission Rule 73 bolsters our conclusion that the Commission is not bound by federal precedent regarding the merger rule.
Finally, we emphasize that the Commission’s decision did not depart altogether from the merger rule. Instead, it declined to apply the merger rule in a situation where the Secretary obtained dismissal by declining to file a complaint. Many federal courts have held that “interlocutory rulings do not merge into a judgment of dismissal for failure to prosecute, and are therefore unappealable.”
See John’s Insulation, Inc. v. L. Addison & Assocs., Inc.,
B.
The Secretary’s second argument is that the Commission arbitrarily and capriciously departed from its
own
past precedent that permitted the Secretary to obtain immediate appeal of an ALJ’s “interlocutory” order by refusing to proceed and thereby obtaining a dismissal. Specifically, she points to past Commission decisions, such as
Northwest Conduit Corp.,

We conclude that the Commission has departed from its established precedent. Below, we discuss the most significant cases cited by the Secretary to illustrate the extent to which the Commission’s decision in the present case was a departure.

In
Northwest Conduit Corp.,

Having established that the Commission has excused the Secretary’s refusal to file a complaint in several past cases involving Rule 60(b) orders, we now turn to the question of whether the Commission adequately distinguished these cases or articulated principled reasons for departing from them. If not, we must deem its decision to be arbitrary and capricious. Although we think that the Commission certainly could have provided better explanations for its decision not to follow these cases, we conclude that they are sufficient to escape classification as arbitrary and capricious.
Of the cases discussed above, the only one that the Commission discusses in depth in its opinion is
Northwest Conduit.
While the Commission in [.Northwest Conduit ] set aside the judge’s vacatur order, excusing the Secretary’s failure to file a complaint, the case before us differs from Northwest Conduit in two key respects. First, in Northwest Conduit, the Secretary could not have successfully petitioned for interlocutory review under Commission Rule 73, 29 C.F.R. § 2200.73, because there was only one Commissioner when the judge ordered the Secretary to file a complaint.... Here, the Secretary could have petitioned for such review because there were two Commissioners at the relevant time. Second, in contrast to Northwest Conduit, the Secretary has foreclosed the possibility of litigating the merits of this case: if we were to reach the Rule 60(b) issue and decide in favor of the Secretary, the NOC would be dismissed and Roy’s Construction would be required to pay the penalty without the benefit of a hearing on the merits; if, upon reaching the Rule 60(b) issue, we were to decide in favor of Roy’s Construction, there would still be no such hearing because the Secretary has waived her right to litigate the merits of the case. In addition to these factual distinctions, we emphasize that the Commission in Northwest Conduit warned the Secretary that “ ‘any party who fails to comply with a Commission order, does so at its peril.’ ”... In light of this warning and the two distinguishing factors, we find that Northwest Conduit does not compel us to set aside the vacatur order.
Sec’y of Labor v. Roy’s Constr., Inc.,
We agree with the Commission that a valid distinction of the present case from
Northwest Conduit
is that interlocutory review was not readily available in the latter case. The specific reference in the
Northwest Conduit
opinion to the absence of the necessary quorum suggested that later decisions may consider this factor when deciding what method the Secretary should use to appeal an unfavorable order. That said, we also recognize that
Northwest Conduit
cited a second factor in support of its conclusion that the Secretary was not obliged to seek interlocutory review: that interlocutory review is generally disfavored.
See Northwest Conduit,
Although the existence of interlocutory review is by itself an adequate reason for the Commission to treat the Secretary’s refusal to file a complaint differently here than in
Northwest,
the Commission’s second factual distinction of
Northwest
provides additional support for its decision. In
Northwest,
the Commission had already affirmed the ALJ’s Rule 60(b) order, so the only obstacle to a hearing on the merits was the ALJ’s belated decision to punish the Secretary for her initial refusal to file a complaint. In the instant case, because the Secretary had renounced any intention of proceeding on the merits if she successfully challenged the Rule 60(b) or
Finally, the Commission in
Northwest
suggests that its holding was intended to be limited to the “unusual circumstances” of the case.
See
The Commission provides a less convincing distinction of the pre-Northwest cases such as Jackson and Byrd that permitted the Secretary to obtain Commission review of an ALJ order after refusing to file a complaint. It does not mention Byrd, and all it says about Jackson is the following:
Although these cases [Northwest Conduit and Jackson ] demonstrate that the Commission has not always treated the Secretary’s failure to file a complaint as a barrier to reaching the merits of the Rule 60(b) issue, the Commission has never affirmatively stated that the Secretary may refuse to file a complaint in order to obtain Commission review. Indeed, only Northwest Conduit was analyzed through the lens of Commission Rule 101(b).

A separate line of cases consists of those in which an ALJ dismisses citations after the Secretary refuses to comply with the ALJ’s discovery order on the ground that the requested information is privileged.

is not extensive. Referring specifically to Braasch’s statement that failure to comply
IV.
Because we have found that the Commission’s decision to uphold the ALJ’s va-catur order without addressing the ALJ’s Rule 60(b) order was not arbitrary, capricious, or an abuse of discretion, we need not address the Secretary’s argument that Roy’s NOC was not filed “within a reasonable time” for Rule 60(b) purposes. We will affirm the judgment of the Commission.

. The ALJ decided that Roy's failure to file a timely NOC before mid-June was the result of “excusable neglect.” He found that Roy’s delay after mid-June was “not due to excusable neglect” but that Roy's was “nonetheless entitled to Rule 60(b) relief” because of Roy's good faith and lack of prejudice to the Secretary. In context, the ALJ's meaning appears to be that although the "control” factor (i.e., Roy's lack of control over the delay due to the move) explains only part of the delay, good faith and lack of prejudice justify a finding of excusable neglect anyway for Rule 60(b) purposes. But the literal meaning of his words is that Rule 60(b) relief should be granted despite the absence of "excusable neglect,” which makes little sense because “excusable neglect” was the only available ground for Rule 60(b) relief. As we explain below, however, our holding does not depend on the qualify of the ALJ’s explanation for granting relief.

Even if the Commission had excused the Secretary's failure to file a complaint, review on the merits would not have occurred if the Commission had reversed the ALJ's Rule 60(b) order. Nonetheless, it is possible to read the Commission's opinion as saying that it will require at least a possibility of a hearing on the merits before excusing the Secretary’s disobedience.

For example, if the Commission allowed the Secretary to obtain review in this manner on a regular basis, we might require a more detailed explanation for a reversal of course. The Secretary cites only a few cases in addition to Jackson, Byrd, and Northwest Conduit, suggesting that this situation arises relatively infrequently and that the precedent was not firmly established.
.The dissenting Commissioner relied largely on the fact that the Secretary had failed to pursue interlocutory review before flouting the ALJ's orders.
