LARSEN, Circuit Judge. Rieth-Riley Construction Company has several jobsites
throughout Michigan. After its unionized employees went on strike in 2018, Rieth-Riley filed
unfair labor practice charges under the National Labor Relations Act (NLRA) against the union
representing the employees. When those charges faltered, Rieth-Riley filed the instant suit in
federal court, challenging then-President Biden’s removal of the National Labor Relations Board’s
(NLRB) General Counsel and the authority of the Acting General Counsel to dismiss Rieth-Riley’s
charges thereafter. Finding the former argument foreclosed by precedent and the latter lacking
merit, we AFFIRM. No. 24-1690, Rieth-Riley Construction Co., Inc. v. Kerwin, et al.
I.
Rieth-Riley is a construction business operating in Indiana and Michigan. Local 324,
International Union of Operating Engineers, AFL-CIO (the Union) is the exclusive collective
bargaining representative for Rieth-Riley’s operating engineers based in Michigan. Michigan
Infrastructure & Transportation Association (MITA) represents Rieth-Riley in collective
bargaining. The Union and MITA have agreed to multiple collective bargaining agreements over
the years, the last ending in June 2018. But in early 2018, the Union refused to bargain with MITA
or Rieth-Riley over a successor agreement. The Union relented slightly in October 2018, agreeing
to bargain with Rieth-Riley only. But the Union subsequentially went on strike at all Rieth-Riley
jobsites throughout Michigan.
Due to alleged incidents of strike misconduct, Rieth-Riley brought an unfair labor practice
charge against the Union in 2019. Unfair labor practice charges “are filed in the first instance with
one of the Board’s . . . Regional Directors, to whom the General Counsel has delegated the initial
power to decide whether or not to issue a complaint.” NLRB v. Sears, Roebuck & Co., 421 U.S.
132, 139 (1975). On May 21, 2020, Regional Director Terry Morgan issued a decision, rejecting
all Rieth-Riley’s allegations except one: that the Union violated § 8(b)(1)(A) of the NLRA by
condoning the physical assault of a truckdriver leaving a Rieth-Riley facility. Rieth-Riley
appealed that decision to the General Counsel’s Office of Appeals. At that time, Peter Robb was
the NLRB’s General Counsel. The Office of Appeals ruled partially in favor of Riley, concluding
that the Union had “arguably violated Section 8(b)(1)(A) of the [NLRA] by engaging in picket
line misconduct, including blocking ingress and egress and impairing visibility at various
Employer facilities, and by engaging in vandalism against certain Employer property.” R. 1-2,
PageID 24. The Office of Appeals remanded the case to the Regional Director, ordering that
-2- No. 24-1690, Rieth-Riley Construction Co., Inc. v. Kerwin, et al.
“[a]bsent settlement, the Regional Director will issue a complaint and an administrative law judge
will holding a hearing.” Id. at 25. The Union didn’t seek reconsideration of the Office of Appeals’
decision.
On remand, Regional Director Morgan issued a formal complaint against the Union. The
complaint contained ten allegations of misconduct against the Union (nine new allegations plus
the original sustained allegation). The Union answered on August 13, 2020. A hearing on the
complaint was to be set for a later date.
On January 20, 2021, however, President Biden removed Robb from his position as NLRB
General Counsel. He appointed Peter Sung Ohr as Acting General Counsel five days later. Shortly
thereafter, the Union filed a request with Regional Director Morgan, asking her to withdraw the
charges in the complaint. Rieth-Riley responded that the request was an impermissible attempt at
reconsideration in violation of NLRB Rule 102.19, and that Acting General Counsel Ohr lacked
authority to withdraw or modify the complaint because he had not been properly appointed. On
March 2, 2021, Regional Director Morgan issued a decision withdrawing the nine new allegations
in the complaint, “[i]n view of the Acting General Counsel’s prosecutorial discretion and after
careful consideration of the evidence adduced during the underlying investigation.” R. 1-6,
PageID 41. That left only the initial allegation related to the assault of a truckdriver. Rieth-Riley
appealed to the Office of Appeals. The Office of Appeals denied the appeal. It rejected
Rieth-Riley’s claim that “the merits of the case should not have been reconsidered and that such
reconsideration reversed previous instructions from the General Counsel.” R. 1-7, PageID 46.
The Office of Appeals explained, “The Acting General Counsel simply exercised his unreviewable
final authority under Section 3(d) of the Act, which includes not only authority to decide whether
to issue unfair labor practice complaints, but also, in some circumstances, authority extending
-3- No. 24-1690, Rieth-Riley Construction Co., Inc. v. Kerwin, et al.
beyond the point at which a complaint has issued, including a purely prosecutorial decision to
withdraw a complaint, effectively a dismissal.” Id. The Office of Appeals additionally explained
that it had “determined that the evidence disclosed by the investigation was insufficient to establish
the merit of the allegations at issue herein.” Id.
Rieth-Riley then filed the instant lawsuit in federal district court, naming Regional Director
Morgan and Acting General Counsel Ohr as defendants.1 Rieth-Riley argued first that Morgan
and Ohr had violated the NLRB’s rules by reconsidering the merits of the case and dismissing the
nine new charges in the administrative complaint. In the alternative, Reith-Riley argued that
defendants lacked authority to act because General Counsel Robb had been improperly removed
from office. Defendants moved to dismiss the lawsuit.
Meanwhile, the administrative proceedings continued. The now-single-issue complaint
went forward against the Union, as part of a hearing consolidated with other related cases.
See Rieth-Riley Constr. Co. v. NLRB (Rieth-Riley I), 114 F.4th 519 (6th Cir. 2024). Rieth-Riley
sought to present evidence of the nine allegations that had been dismissed, but the ALJ and the
Board refused to consider those allegations. Id. at 535–36. The agency also rejected Rieth-Riley’s
argument that General Counsel Robb’s removal had been unlawful. Id. at 529.
Rieth-Riley petitioned for review of those rulings. A panel of this court denied the petition
for review and granted the Board’s cross-petition for enforcement. Id. The panel declined to
address the withdrawn allegations and agreed with the agency that Robb had been lawfully

Constr. Co v. NLRB, No. 24-767, 2025 WL 889152 (U.S. Mar. 24, 2025).
Back to the instant lawsuit. Before this court ruled in Rieth-Riley I, the district court
granted defendants’ motion to dismiss. The court concluded that it could not review whether the
General Counsel’s decision to withdraw the nine new allegations in the complaint violated NLRB
rules because the General Counsel had unreviewable discretion as to prosecutorial actions. For
the same reason, the district court declined to review the General Counsel’s denial of Rieth-Riley’s
appeal. It further concluded that it did not have jurisdiction to review the argument that General
Counsel Robb had been unlawfully removed from office. Rieth-Riley now appeals that decision.
II.
We review de novo a district court’s decision granting a motion to dismiss under Federal
Rule of Civil Procedure 12(b)(1) for lack of subject-matter jurisdiction or Rule 12(b)(6) for failure
to state a claim. Patton v. Fitzhugh, 131 F.4th 383, 391 (6th Cir. 2025); US Framing Int’l LLC
v. Cont. Building Co., -- F.4th --, 2025 WL 1024422, at *4 (6th Cir. 2025).
A.
Rieth-Riley argued below and in its opening brief to this court that then-President Biden
unlawfully removed General Counsel Robb from office and that any decisions by the Acting
General Counsel after that removal were taken without statutory authority. But, as Rieth-Riley
now acknowledges, binding precedent forecloses that argument. Rieth-Riley I held that “President
Biden lawfully removed former General Counsel Robb,” and that subsequent actions brought by
then-Acting General Counsel Ohr were “proper.” 114 F.4th at 531. As previously explained, the
en banc court denied review of that ruling, and so did the Supreme Court. We are bound by the
-5- No. 24-1690, Rieth-Riley Construction Co., Inc. v. Kerwin, et al.
panel’s holding. See Wright v. Spaulding, 939 F.3d 695, 700 (6th Cir. 2019). And it forecloses
Rieth-Riley’s argument regarding the propriety of General Counsel Robb ‘s removal.
B.
Rieth-Riley’s only remaining argument is that Regional Director Morgan and Acting
General Counsel Ohr violated agency regulations by dismissing the nine new allegations from the
complaint. According to Rieth-Riley, 29 C.F.R. § 102.19(c) provides the only mechanism for
overturning an appeal decision by the General Counsel. That regulation allows a party to move
for reconsideration of an appeal decision within fourteen days. 29 C.F.R. § 102.19(c). The Union
did not timely move to reconsider General Counsel Robb’s decision adding the nine new
allegations to the administrative complaint. So, Reith-Riley posits, when Regional Director
Morgan and General Counsel Ohr dismissed the new allegations on remand, they violated agency
regulations. And that gave the district court subject-matter jurisdiction under U.S. ex rel. Accardi
v. Shaughnessy, 347 U.S. 260 (1954). The district court disagreed, determining that it could not
review Rieth-Riley’s claim because the action was part of the General Counsel’s unreviewable
prosecutorial discretion.
The NLRA forbids employers and labor organizations from engaging in unfair labor
practices. 29 U.S.C. § 158. The General Counsel has “final authority, on behalf of the Board, in
respect of the investigation of charges and issuance of complaints . . . , and in respect of the
prosecution of such complaints before the Board.” 29 U.S.C. § 153(d). The General Counsel thus
operates in a “prosecutorial” capacity, whereas the Board operates an “adjudicatory” one. NLRB
v. United Food & Comm. Workers Union, Loc. 23, AFL-CIO, 484 U.S. 112, 124 (1987).
“[A]n agency’s decision not to prosecute or enforce, whether through civil or criminal
process, is a decision generally committed to an agency’s absolute discretion” and is not, generally,
-6- No. 24-1690, Rieth-Riley Construction Co., Inc. v. Kerwin, et al.
subject to judicial review. Heckler v. Chaney, 470 U.S. 821, 831 (1985). This is also true in the
specific context of the NLRA. The Supreme Court has examined the General Counsel’s
discretionary authority to prosecute or withdraw complaints. It has recognized that the NLRA
grants the General Counsel “‘final authority’ regarding the filing, investigation, and ‘prosecution’
of unfair labor practice complaints.” Loc. 23, AFL-CIO, 484 U.S. at 124. The Board’s role, by
contrast, is “the adjudication of complaints.” Id. General Counsel “decisions” regarding “whether
to file a complaint are prosecutorial.” Id. at 125. And “until a hearing is held the Board has taken
no action; no adjudication has yet taken place.” Id. So, the Court concluded, “until the hearing
begins, settlement or dismissal determinations are prosecutorial.” Id. at 125–26. And those
determinations are unreviewable. As the Court explained: “[W]e fail to see why the General
Counsel should have the concededly unreviewable discretion to file a complaint, but not the same
discretion to withdraw the complaint before hearing if further investigation discloses that the case
is too weak to prosecute.” Id. at 126.
That is exactly what happened here. No hearing before the Board had occurred. Instead,
after remand from the General Counsel’s Office of Appeals, Regional Director Morgan dismissed
the new allegations. Morgan made the decision “[i]n view of the Acting General Counsel’s
prosecutorial discretion and after careful consideration of the evidence adduced during the
underlying investigation.” R. 1-6, PageID 41. Consistent with caselaw, the Regional Director had
the “unreviewable discretion” to withdraw the complaint at that time. Loc. 23, AFL-CIO, 484 U.S.
at 126; see also Rieth-Riley I, 114 F.4th at 536 (“Because the decision not to prosecute certain
allegations was within the General Counsel’s prosecutorial discretion, it cannot be reviewed by
this court under the NLRA.”); Tensing v. NLRB, 519 F.2d 365, 365 (6th Cir. 1975) (per curiam)
(dismissing for lack of jurisdiction because “district courts may not review the refusal of the
-7- No. 24-1690, Rieth-Riley Construction Co., Inc. v. Kerwin, et al.
Board’s General Counsel to investigate or to file a complaint concerning unfair labor practice
charges”); Mayer v. Ordman, 391 F.2d 889, 889 (6th Cir. 1968) (per curiam) (The NLRA
“precludes District Court review of the manner in which the General Counsel . . . investigates
unfair labor practice charges and determines whether to issue a complaint thereon.”).
Rieth-Riley acknowledges that courts may not review a General Counsel decision on
“whether it [was] a good idea or a bad idea to prosecute or not any particular violation of the law.”
Reply Br. at 6. But it says that its claim instead focuses on defendants’ “disregard[] [for] the
procedural requirements for making that decision.” Id. at 7. This, according to Rieth-Riley, is
subject to judicial review under U.S. ex rel. Accardi v. Shaughnessy, 347 U.S. 260 (1954).
“Accardi has come to stand for the proposition that agencies may not violate their own rules and
regulations to the prejudice of others.” Battle v. F.A.A., 393 F.3d 1330, 1336 (D.C. Cir. 2005).
Rieth-Riley’s “Accardi-claim” is difficult to divorce from the General Counsel’s otherwise
unreviewable prosecutorial discretion, as the district court here seemed to recognize. But to the
extent that Rieth-Riley’s argument is focused solely on the Acting General Counsel’s failure to
hold the Union to the requirements of 29 C.F.R. § 102.19(c), we believe that Rieth-Riley
has nominally asserted a claim that the agency has failed to follow its own regulations. Id.
A hypothetical helps show why. Imagine that the NLRB had a rule that after the 14-day window
for reconsideration closes, the General Counsel is stripped of prosecutorial discretion and is bound
to prosecute each allegation of the complaint as determined by the Office of Appeals. If the
General Counsel declined to follow that rule and instead dismissed the complaint, surely the losing
party would have an Accardi claim. Likewise, Reith-Riley’s claim that the General Counsel
violated the requirements of § 102.19(c) comes within Accardi’s ambit. Nonetheless, we must
still affirm the district court because the claim here is meritless. See Angel v. Kentucky, 314 F.3d
-8- No. 24-1690, Rieth-Riley Construction Co., Inc. v. Kerwin, et al.
262, 264 (6th Cir. 2002) (stating that we may affirm the district court for any reasons supported
by the record).
Rieth-Riley stretches the alleged rule violation too far. Unlike the hypothetical regulation
discussed above, 29 C.F.R. § 102.19(c) does nothing to constrain the General Counsel’s discretion.
It merely sets limits on when a party may seek reconsideration. See 29 C.F.R. § 102.19(c) (“A
motion for reconsideration of the decision must be filed within 14 days of service.”). It does
nothing to limit the General Counsel’s unreviewable discretion to further investigate the alleged
“charges and determine[] whether to issue a complaint thereon.” Mayer, 391 F.2d at 889. After
all, no adjudicatory hearing before the NLRB had occurred here, meaning that the General Counsel
was free to change his mind. Loc. 23, AFL-CIO, 484 U.S. at 124; cf. NLRB v. O’Neill, 965 F.2d
1522, 1528 (9th Cir. 1992) (“The unions’ failure to appeal or file a motion for reconsideration does
not bar the General Counsel or the Regional Director from reinstating a complaint on their own
motion.”).
What’s more, the Regional Director rested her decision to withdraw the new allegations on
“the Acting General Counsel’s prosecutorial discretion and . . . careful consideration of the
evidence adduced during the underlying investigation.” R. 1-6, PageID 41. Perhaps that decision
was prompted by the Union’s request to reconsider the allegations (though the Regional Director’s
order doesn’t reflect this). But Rieth-Riley points to no language, whether it be statutory,
regulatory, or based in caselaw, limiting the Regional Director from making such a determination
on remand from the Office of Appeals, whether prompted by a party or issued sua sponte. After
all, the Regional Director’s authority stems directly from the General Counsel, see Sears, Roebuck
& Co., 421 U.S. at 139, who remained free to change his mind until a hearing before the NLRB,
see Loc. 23, AFL-CIO, 484 U.S. at 125–26. And if the Regional Director overstepped that
-9- No. 24-1690, Rieth-Riley Construction Co., Inc. v. Kerwin, et al.
authority on remand, there was a mechanism to correct it—another appeal to the Office of Appeals.
See Sears, Roebuck & Co., 421 U.S. at 140–41. Here, that body confirmed the Regional Director’s
decision, finding that it was within the Acting General Counsel’s prosecutorial discretion and also
appropriate on the merits. Rieth-Riley has failed to establish that the Acting General Counsel
violated agency rules in the process.
