Vacated and remanded by published opinion. Judge DAVIS wrote the opinion, in which Judge NIEMEYER and Judge Shedd Joined.
OPINION
In this appeal, we address the interpretation of a provision of the Sarbanes-Oxley Act of 2002, 18 U.S.C. § 1514A, governing the filing of whistleblower lawsuits in federal district court. The parties acknowledge that the Sarbanes-Oxley Act expressly provides a United States District Court jurisdiction to entertain a whistleblower action. However, they disagree as to whether a whistleblower plaintiff, during the pendency of an administrative appeal of an Administrative Law Judge’s (“ALJ”) ruling, has the right to a de novo proceeding in district court. In the absence of guidance from this Court, or other circuit courts, the district court granted the defendants’ motion to dismiss the district court action in favor of remand to the appropriate administrative body for further proceedings. In light of the language of the statutory provisions at issue, we *241 reverse the district court and remand for further proceedings consistent with this opinion.
I.
David Stone (“Stone” or “Appellant”) was employed by Instrumentation Laboratory Company (“ILC”) from 1999 through 2006. ILC is in the business of developing, manufacturing, and distributing critical care and diagnostic instruments, as well as other related products and services, for use primarily in hospital laboratories. Stone began as an ILC Sales Representative in 1999, was promoted to Sales Manager in 2002, and was again promoted in 2005 to Director of National Accounts. During his employment at ILC, Stone received numerous accolades for his performance. 1
As Director of National Accounts, one of Stone’s responsibilities was working with Group Purchasing Organizations (“GPOs”), which are strategic affiliations of hospitals that concentrate buying power in order to negotiate lower prices. ILC had contracts with various GPOs requiring that, among other things, ILC maintain a GPO membership database, offer contractually negotiated prices and terms to GPO members, and pay administrative fees to GPOs equal to three percent of sales revenue generated from member purchases. ILC has acknowledged in public disclosures to shareholders that GPOs are a critical part of its distribution strategy.
After assuming his role as Director of National Accounts, Stone learned that Brian Durkin (“Durkin”), one of Stone’s superiors at ILC, was not accurately tracking, reporting, and paying the required administrative fees to GPOs. Durkin’s omissions resulted in a multi-year cumulative liability of at least half a million dollars and threatened ILC’s ability to sell products to most of its customers. Stone’s Complaint asserts that Durkin’s failure to maintain adequate internal controls and track administrative fees resulted in ILC “misrepresenting its financial condition to shareholders.” (Comply 70.) Stone’s discovery regarding administrative fees prompted him to perform additional investigation into ILC’s internal controls, and such investigation revealed numerous weaknesses.
From September of 2005 until March of 2006, Stone repeatedly voiced his concerns about deficient internal controls and unpaid GPO fees to Durkin and two other ILC managers. 2 Stone’s efforts were repeatedly met with resistance and even unequivocal refusals to correct the problems. Stone contends that Appellees retaliated against him after he brought such deficiencies to light, and that such retaliation culminated in Stone’s termination in March of 2006.

A.
On June 19, 2006, pursuant to the Sarbanes-Oxley Act, Stone filed a retaliation claim with the Occupational Safety and Health Administration (“OSHA”), which hears such claims on behalf of the Secretary of Labor (“the Secretary”). OSHA issued its preliminary findings on January
*242 3, 2007, more than 180 days after Stone’s claim was filed. Pursuant to the governing regulations, Stone timely objected to OSHA’s findings and requested a hearing before an ALJ. On March 1, 2007, Appellees filed a motion for summary decision before the ALJ. In response, Stone moved to delay consideration of such motion to permit him to take discovery. Stone’s motion for discovery was denied, 3 and the ALJ granted Appellees’ motion for summary decision on September 6, 2007. Stone thereafter successfully petitioned the Administrative Review Board (“ARB”) for review of the ALJ’s order. On October 1, 2007, the ARB established a briefing schedule, which was thereafter modified by the ARB on Stone’s motion.
On November 8, 2007, more than a month before Stone’s initial brief was due under the modified briefing schedule, Stone filed a notice with the ARB stating his intention to bring a de novo action in federal district court. The ARB then issued an order to show cause why the administrative appeal should not be dismissed. After Appellees failed to respond, and after receiving notice from Stone that he had in fact filed suit in federal court, the ARB dismissed the administrative appeal. Such dismissal was not based on the merits, but appears to be an acknowledgment that, no “bad faith” having been alleged by ILC, the ARB lost jurisdiction over the matter once Stone’s complaint was filed in district court.
B.
Stone’s Sarbanes-Oxley Act whistle-blower suit was filed in the United States District Court for the District of Maryland on November 26, 2007. On March 27, 2008, Appellees timely filed a motion to dismiss pursuant to Federal Rule of Civil Procedure 12(b)(6). After the matter was fully briefed, on July 1, 2008, the district court granted such motion based on preclusion principles, finding that the ALJ’s ruling was a “final judgment on the merits” for purposes of collateral estoppel. (J.A. 168-69.) In so ruling, the court rejected Stone’s claim that he did not have a “full and fair opportunity to litigate his claims before the ALJ” and indicated that permitting Stone to pursue relief in federal district court would be “wasteful.” (J.A. 169.) The district court did, however, “issue a mandamus to the [Department of Labor] to re-instate proceedings” and further ordered the ARB “to rule on the merits of Stone’s appeal within 90 days.... ” (J.A. 169.)
Although the district court granted the motion to dismiss and ordered further administrative proceedings, it did not dismiss the civil action before it, opting instead to stay the proceedings. Stone thereafter sought certification to file an appeal to this Court, but that motion was ultimately denied. Stone declined to further prosecute his administrative appeal before the ARB because he believed that the filing of his complaint in district court divested the ARB of jurisdiction. Based on Stone’s failure to prosecute, the ARB entered a final order of dismissal and Stone thereafter obtained a final judgment from the district court on his dismissed whistleblower claim. Stone now appeals the dismissal of his district court action.

The Sarbanes-Oxley Act provides employees of publicly traded companies with whistleblower protection, prohibiting employers from terminating, or otherwise retaliating against, such employees when they report “potentially unlawful conduct” that has occurred or is in progress,
Welch v. Chao,

see also Welch,
(A) filing a complaint with the Secretary of Labor; or
(B) if the Secretary has not issued a final decision within 180 days of the filing of the complaint and there is no showing that such delay is due to the bad faith of the claimant, bringing an action at law or equity for de novo review in the appropriate district court of the United States, which shall have jurisdiction over such an action without regard to the amount in controversy.
18 U.S.C. § 1514A(b)(l) (emphasis added).
The Department of Labor’s (“DOL”) regulations implementing § 1514A set forth the procedure governing the administrative review process for such whistle-blower claims as well as the procedure for notifying the DOL of a complainant’s intent to file suit in federal court for lack of a “final” administrative decision within 180 days. To the extent that such regulations fill in procedural gaps left by the statute and do not conflict with statutory language, we afford them deference.
See Yashenko,
The first DOL administrative ruling on a Sarbanes-Oxley whistleblower claim takes the form of preliminary OSHA findings, which can thereafter be challenged before an ALJ. 29 C.F.R. § 1980.106(a). The ALJ’s decision on such a challenge “will contain appropriate findings, conclusions, and an order ....’’Id. § 1980.109(a). A complainant can further challenge an adverse ALJ ruling through the filing of a “petition for review” with the ARB. Id. § 1980.110(a). If the ARB does not accept the petition for review, then the “decision of the [ALJ] will become the final order of the Secretary....” Id. § 1980.110(b). If, however, the ARB accepts a complainant’s petition for review, “the decision of the administrative law judge will be inoperative unless and until the Board issues an order adopting the decision ...” Id. (emphasis added). 5
*245 After the Secretary issues a final decision, the Act provides that such decision can be appealed directly to the appropriate circuit court of appeals. See 18 U.S.C. § 1514A(b)(2)(A); 49 U.S.C. § 42121(b)(4). However, if a “final” administrative decision has not been timely issued and a complainant desires de novo review in district court, the DOL regulations provide that a complainant must file a “notice of his or her intention to file such a [federal] complaint.” 29 CFR § 1980.114(b). The notice must be provided fifteen days in advance of filing the federal suit, and should be filed with “the [ALJ] or the [ARB], depending on where the proceeding is pending.” Id. (emphasis added).
With the above statutory and regulatory backdrop, we now turn to the central question before us — whether the district court had authority to dismiss Stone’s complaint by applying preclusion principles.
C.
The relevant portion of the Sarbanes-Oxley whistleblower statute states that an aggrieved individual may bring “an action at law or equity for de novo review in the appropriate district court of the United States” if a final decision has not been issued by the Secretary of Labor within 180 days after the filing of an administrative complaint. 18 U.S.C. § 1514A(b)(l)(B). Starting, as we must, with the text of the statute, we find the above quoted language to be plain and unambiguous. It is undisputed that, here, the Secretary did not issue a final decision within 180 days and that Stone followed the procedure set forth in the regulations to exercise his statutory right to seek relief in district court.
Although the action in district court was properly filed and the court acknowledged its jurisdiction over the suit, in granting Appellees’ motion to dismiss, the district court relied on its inherent power to apply preclusion principles, issue a mandamus, and order the DOL to re-instate administrative proceedings. (J.A. 168-69.) The district court explained that because Stone had “a full and fair opportunity to litigate his claims before an ALJ, which resulted in a final judgment on the merits, it would be wasteful to relitigate the[] claims” in district court. (J.A. 169.) In reaching such conclusion, the district court relied in part on the Secretary’s public comments on § 1514A, as well as on a similar finding by an out of circuit district court in Allen v. Stewart Enterprises, Inc., No. 05-4033 (E.D.La. Apr. 6, 2006) (unpublished).
In applying preclusion principles, the district court strayed from the plain and unambiguous meaning of § 1514A(b)(l)(B). The district court need not have reached any DOL interpretive regulations, or the Secretary’s comments to such regulations, to define a complainant’s right to a de novo review in district court. The text of the statute is clear — if the DOL has not reached a final decision within the time period established by Congress, a complainant has the statutory right not merely to undefined relief in another forum, but to “de novo review” in federal district court. 18 U.S.C. § 1514A(b)(l)(B). A plaintiffs right to pursue such relief is not circumscribed in any manner by the statute.
Appellees argue, however, that although the statute does not preclude a
*246
plaintiff from seeking such relief, nothing in the text of the statute, its procedural regulations, or its legislative history, “abrogated] the District Court’s long-recognized power to prevent needless duplicative litigation by applying collateral estoppel.” (Appellees’ Brief 17.) Although we agree that district courts generally have the ability to give preclusive effect to final administrative rulings,
Collins v. Pond Creek Mining Co.,
To further clarify the import of Congress’s establishment of a right to
“de novo
review,” we have previously discussed in detail the difference between preclusive findings of state ALJs on § 1983 claims, and non-preclusive findings of state ALJs on Title VII claims.
Rao v. County of Fairfax, Va.,
Here, the controlling statute does not provide that a district court give any
deference
to prior administrative findings but instead requires performance of a
de novo
*247
review.
7
Accordingly, deferring to the administrative agency, even if more efficient, is in direct conflict with the unambiguous language of the Sarbanes-Oxley Act.
Astoria Federal Sav. & Loan Ass’n v. Solimino,
D.
As the plain language of § 1514A(b)(l) mandates a
de novo
review by the district court which will, if an ALJ has already issued a ruling, likely result in some duplication of efforts, we next consider whether such literal interpretation of the statute leads to an “absurd result.”
Chesapeake Ranch Water Co.,
In support of the contention that it would be “absurd” to permit de novo review in district court following a full hearing before an ALJ, Appellees rely in part on the Secretary of Labor’s comments to the regulations implementing § 1514A(b)(l). After explaining that the text of the Sarbanes-Oxley whistleblower provisions is “unique” because it creates the possibility that a complainant will turn to a district court while an appeal is pending before the ARB, the Secretary opines:
The Secretary believes that it would be a waste of the resources of the parties, the Department, and the courts for complainants to pursue duplicative litigation. The Secretary notes that the courts have recognized that, when a party has had a full and fair opportunity to litigate a claim, an adversary should be protected from the expense and vexation of multiple lawsuits and that the public interest is served by preserving judicial resources by prohibiting subsequent suits involving the same parties making the same claims.... Therefore, the Secretary anticipates that Federal courts will apply [preclusion] principles if a complainant brings a new action in Federal court following extensive litigation before the Department that has resulted in a decision by an administrative law *248 judge or the Secretary. Where an administrative hearing has been completed and a matter is pending before an administrative law judge or the Board for a decision, a Federal court also might treat a complaint as a petition for mandamus and order the Department to issue a decision under appropriate time frames.
Procedures for the Handling of Discrimination Complaints Under Section 806 of the Corporate and Criminal Fraud Accountability Act of 2002, Title VIII of the Sarbanes-Oxley Act of 2002, 69 F.R. 52104, 52111-12 (Aug. 24, 2004) (emphasis added). The Secretary goes on to note that although public comments to the regulations suggested that the DOL “specifically incorporate preclusion principles” into the regulations, such step was not taken because “there is no statutory basis for including preclusion principles in the[ ] regulations ....” Id.
Notwithstanding the Secretary’s “anticipation” on how courts will interpret and apply § 1514A(b)(i), the Secretary’s invitation to transform a right to
de novo
review in district court into a request for mandamus cannot be squared with the statutory language chosen by Congress. Although, in the eyes of the Secretary, Congress’s decision to permit duplication of efforts is problematic, neither Appellees nor the Secretary present a compelling argument as to why such duplication is “absurd.” Congress unquestionably chose an aggressive timetable for resolving whistleblower claims and reasonably created a cause of action in an alternative forum should the DOL fail to comply with such schedule.
8
A natural result of the aggressive timeframe is that efforts will be duplicated when the DOL engages in a thorough, yet administratively non-“final”, process that fails to resolve the administrative case within the prescribed time-frame. Neither the Secretary nor the courts have the authority to engage in creative interpretation of the statute to avoid duplication of efforts, even if the goal for doing so is laudable.
See Lamie v. U.S. Trustee,
Regardless of whether the DOL has, in practice, found it unrealistic to comply with Congress’s aggressive timetable,
9
Congress plainly has the authority, in balancing speed against resources, to rationally weigh timeliness as a more compelling concern and provide that proceedings begin anew in district court if the DOL is unable to reach a final decision within 180 days.
See Elliott,
We therefore find that a literal interpretation of the statute does not lead to an “absurd result.” In so finding, we reject as contrary to the statute the Secretary’s “suggestion” that district courts apply preclusion principles to effectuate a goal of efficiency. First, as noted above, the plain text of the statute expressly provides a complainant the right to
de novo
review. Second, the DOL’s own regulations acknowledge that a district court action may be filed while an appeal is pending before the ARB.
See
29 CFR § 1980.114(b) (requiring that the ARB be notified of intent to file a federal suit if an ALJ’s ruling is on appeal to the ARB). Third, even though preclusion principles are
generally
favored, “[e]ourts do not, of course, have free rein to impose rules of preclusion” if it was not intended by the legislature.
Astoria,
IV.
In summary, the plain language of § 1514A(b)(l)(B) unambiguously establishes a Sarbanes-Oxley whistleblower complainant’s right to de novo review in federal district court if the DOL has not issued a “final decision” and the statutory 180-day period has expired. Here, regardless of whether the ALJ conducted a hearing or issued findings, it is undisputed that: (1) the administrative process did not yield a “final decision” for purposes of § 1514A(b)(l)(B) at the time Stone exercised his right to file suit in district court; and (2) the 180-day period established by Congress expired prior to Stone filing suit. Therefore, notwithstanding the Secretary’s view on the soundness of Congress’s decision to create a framework allowing for duplication of efforts, such framework is precisely what Congress reasonably and unambiguously provided for in the controlling statute.
Accordingly, even if the 180-day statutory period is arguably both overly aggressive and not the most efficient use of administrative and judicial resources, Stone was entitled to de novo review in the court below. In the absence of any guidance from this court, or any other circuit court, *250 as well as in the face of the Secretary’s comments inviting district courts to remand cases to the ARB, the district court understandably erred in applying preclusion principles. As stated above, we reject the Secretary’s interpretation and invitation to district courts to apply preclusion principles because Congress expressly provided for de novo non-deferential review in district court. A literal interpretation of the statute’s plain language does not lead to an absurd result since Congress unquestionably has the right to create a complainant-friendly statutory scheme that affords no deference to non-final agency findings.
For the reasons stated herein, we reverse the district court’s order granting Appellees’ motion to dismiss, vacate the entry of final judgment, and remand to the district court for further proceedings consistent with this opinion.
VACATED AND REMANDED
Notes
. As the instant appeal challenges the district court's dismissal under Federal Rule of Civil Procedure 12(b)(6), "we accept as true all well-pleaded allegations and view the complaint in the light most favorable to [Stone].”
Venkatraman v. REI Systems, Inc.,
. Stone's Complaint names all three superiors as defendants: Brian Durkin, Ann DeFronzo, and Ramon Benet. ILC and the individually named ILC managers are referred to herein collectively as "Appellees.”
. Stone had previously agreed, during a telephone status conference, that discovery would be stayed pending the ALJ's ruling on the motion for summary decision. Notwithstanding such inconsistent positions, there is no allegation that Stone acted in "bad faith” to delay the administrative process.
. The court below noted the lack of case law interpreting the relevant Sarbanes-Oxley Act provision and cited to two district court cases, one of which squarely addressed the question before the district court. (J.A. 166-68.)
See Allen v. Stewart Enters.,
No. 05-4033 (E.D.La. Apr. 6, 2006) (unpublished) (giving preclusive effect to the ALJ’s ruling on the plaintiff’s administrative whistleblower claim and granting a petition for mandamus that effectively remanded the case to the ARB for further proceedings);
Hanna v. WCI Cmtys., Inc.,
. We defer to the DOL’s established procedure for processing and ruling on an adminis
*245
trative whistleblower claim, and such procedure necessarily defines what constitutes a "final decision” of the Secretary. Such deference to the DOL’s reasonable implementation of the Sarbanes-Oxley Act is appropriate regardless of whether the court views the DOL’s procedural scheme as merely “filling explicit gaps in the statute” or "clarifying” the phrase "final decision” as used in the statute.

See E.I. Du Pont de Nemours & Co. v. Richmond Guano Co.,
. The benefit of the aggressive timetable established by Congress does not inure solely to the benefit of complainants, as § 1514A presents complainants an extremely limited window to file a claim, providing that a whistle-blower action "shall be commenced not later than 90 days after the date on which the violation occurs.” 18 U.S.C. § 1514A(b)(2)(D). The fact that the statute requires both the DOL and the complainant to act swiftly further evidences the weight Congress placed on the timely resolution of whistleblower claims.
. The ARB noted in a footnote to its November 15, 2007 Order to Show cause that: "As is the usual case, by the time the Board received the petition for review, the 180-day period for deciding the case had already expired.” (J.A. 105.)
