             Appeal from the United States District Court for the
                          Western District of Texas


Before BARKSDALE, HIGGINSON, and DUNCAN, Circuit Judges.
STEPHEN A. HIGGINSON, Circuit Judge:
      This appeal asks the court to determine the limits of an arbitrator’s
powers to reconsider a previously issued decision. Communications Workers of
America, AFL-CIO (“CWA”), a union representing employees of Southwestern
Bell Telephone Company (“the Company”), filed a grievance against the
Company in May 2015. Though the arbitrator initially sided with CWA and
found that the Company had violated the parties’ collective bargaining

                                 No. 19-50686
agreement (“CBA”), he later vacated his earlier decision and issued a modified
decision. The district court upheld the arbitrator’s actions, holding that his
interpretation of his powers was consistent with the CBA.
        Guided by the “extraordinarily narrow” standard of review that applies
to our consideration of arbitration awards, see Rain CII Carbon, LLC v.
ConocoPhillips Co., 674 F.3d 469, 471–72 (5th Cir. 2012) (citation omitted), we
AFFIRM.
                                       I.
        CWA and the Company are parties to a CBA. Under the terms of the
CBA, the parties agreed to resolve all disputes by arbitration. The CBA
provides that arbitrations “shall be conducted under the then obtaining rules
of the Voluntary Labor Arbitration Tribunal of the American Arbitration
Association”—also known as the AAA Rules. Decisions rendered by the
arbitrator “shall be final, and the parties agree to be bound and to abide by”
them.
        In May 2015, CWA filed a grievance against the Company. It argued that
the Company had violated the CBA by assigning cable-splicing activities to
Premises Technicians (“Prem Techs”), a group of workers employed by the
Company. CWA argued that these activities had not been explicitly assigned
to Prem Techs in either the parties’ settlement agreements or in the position’s
official job description. By contrast, the official job descriptions for Customer
Service Technicians and Cable Splicing Technicians, two other groups of
Company employees, included “[s]plic[ing] wires” on the list of “essential
functions” for those roles.
        The Company argued that its actions complied with the CBA and with
the parties’ mutual understandings. It observed that a settlement agreement
reached by the parties during their 2009 collective bargaining process granted
the Company the right to “[a]ssign Premises Technicians all work from and
                                       2

                                       No. 19-50686
including the Serving Terminal up to and including the customer premises for
IP enabled products and services.” 1 In 2013, the parties reached a new
settlement agreement that retained the same “all work” language. Because
this expansive language encompassed cable splicing activities, the Company
argued that it had not strayed from the CBA when it assigned these tasks to
Prem Techs.
       On October 18, 2017, Samuel Nicholas, Jr. (“the arbitrator”), presided
over a hearing to resolve this dispute. Over the Company’s objections, the
arbitrator allowed CWA to introduce Union Exhibit 4 into evidence. The
exhibit detailed specific agreements between AT&T Midwest and a CWA
bargaining unit located in the Midwest—District 4. Union Exhibit 4 revealed
that fusion splicing had been specifically excluded from the list of tasks
assigned to Prem Techs in District 4. 2 During the hearing, Charlie Torres, the
President of the Union, admitted that there was no similar document excluding
splicing tasks from Prem Techs’ responsibilities in District 6—the district at
issue in this arbitration.
       The arbitrator issued his first decision on January 19, 2018 (“the
January award”). He sustained CWA’s grievance and held that the Company
had violated the parties’ CBA by assigning cable-splicing tasks to Prem Techs.
The arbitrator explained that the broad “all work” language in the Settlement
Agreement supported the Company’s argument that it was entitled to assign
these tasks to Prem Techs. Nevertheless, he concluded that the “past practice”
of the parties compelled a different conclusion. He found that “Union Exhibit



       1The “Serving Terminal” is a green pedestal or cylinder located in a customer’s yard.
       2 The parties do not explain the distinction, if any, between “fusion splicing” and the
cable splicing at issue in this arbitration. However, according to CWA, the fact that Union
Exhibit 4 specifically identifies “fusion splicing” demonstrates that the parties knew how to
negotiate regarding specific job tasks, suggesting that their failure to do so here demonstrates
that they did not intend for these activities to be assigned to Prem Techs.
                                               3
    Case: 19-50686     Document: 00515368555     Page: 4   Date Filed: 04/01/2020



                                  No. 19-50686
4 reveals the established method . . . which the parties utilize to make changes
to a Premises Technician’s job duties.” Because the parties had never formally
negotiated to have cable splicing added to the job duties of Prem Techs, the
arbitrator concluded that the Company violated the CBA and the parties’
agreed-upon practice when it assigned this work. Even though he found a
violation, however, the arbitrator noted that he “would be inclined to find that
no violation of the Agreement occurred” if not for his reliance on Union Exhibit
4, which demonstrated the “clear practice that the parties have chosen to abide
by.” He ordered the parties to negotiate any further changes to the job
description for Prem Techs, and “retain[ed] jurisdiction [over] the award.”
      A few days later, the Company filed a motion for reconsideration. It
argued that the arbitrator’s reliance on Union Exhibit 4 was misplaced because
that exhibit “was a different union’s summary of a . . . different bargaining unit
having a different collective bargaining agreement.” Given the arbitrator’s
explicit statement that he would have found in favor of the Company if not for
the “clear practice” established by Union Exhibit 4, the Company argued that
the arbitrator should reconsider his earlier decision.
      Though the Union argued that the Company’s requested relief was
outside the scope of the arbitrator’s powers, the arbitrator agreed with the
Company and issued a new decision on February 23, 2018 (“the February
award”). In the February award, the arbitrator explained that he had
incorrectly relied upon Union Exhibit 4 in reaching his earlier decision.
Consistent with his reasoning in the January award, he found that he was now
compelled to conclude that no violation had occurred, and he sided with the
Company. The arbitrator held that the AAA rules empowered him to make this
modification because they permitted him to correct a “clerical, typographical,
technical, or computational error[]” contained in an earlier award. Though the
Union observed that AAA Rule 40 prohibited an arbitrator from modifying his
                                        4
    Case: 19-50686    Document: 00515368555     Page: 5   Date Filed: 04/01/2020

award in a manner that “re-determine[d] the merits of a[] claim already
decided,” the arbitrator classified his earlier reliance on Union Exhibit 4 as a
“technical error” that could be corrected without violating this prohibition.
Thus, he found that his actions were supported by the rules and by the parties’
CBA, and he found in favor of the Company.
      CWA filed suit to enforce the January award and vacate the February
award. The Company filed a counterclaim seeking enforcement of the February
award, and the parties cross-moved for summary judgment. The district court
referred the motions to a magistrate judge, who issued a Report and
Recommendation (R&R) advising the district court to grant summary
judgment to the Company. The district court adopted the R&R over CWA’s
objections and confirmed the February award. This appeal followed.
                                       II.
      “We review the district court’s confirmation of an arbitrator’s award de
novo, but our review of the arbitrator’s award itself . . . is very deferential.”

omitted), and “severely limited,” Manville Forest Prods. Corp. v. United
Paperworkers Int’l Union, AFL-CIO, 831 F.2d 72, 74 (5th Cir. 1987)—one of

      Courts are not permitted “to reconsider the merits of an [arbitration]
award.” Misco, 484 U.S. at 36. Instead, we must affirm an arbitral award “as
long as the arbitrator is even arguably construing or applying the contract and
acting within the scope of his authority.” Id. at 38. Even if an arbitrator
committed serious error, we may not reverse the arbitrator’s judgment if the
decision “draw[s] its essence from the contract.” Id.; see also Oxford Health

of an arbitrator’s error—even his grave error—is not enough” to justify

                                        III.
      This uniquely deferential standard of review compels us to affirm the
district court and uphold the arbitrator’s February award.
      CWA argues that the arbitrator exceeded his authority when he
rescinded the January award and issued the February award. An arbitrator
exceeds his authority when he “ignore[s] the plain language of a contract.”

2018) (citations omitted); see id. (distinguishing between an arbitrator’s role in
“applying or interpreting the agreement” and “rewriting it”). “[A]n arbitrator
is confined to interpretation and application of the collective bargaining
agreement; he does not sit to dispense his own brand of industrial justice.”
United Steelworkers of Am. v. Enter. Wheel & Car Corp., 363 U.S. 593, 597
(1960). To determine whether an arbitrator exceeded his authority, courts
apply the “essence test,” evaluating whether the arbitration award “ha[s] a
basis that is at least rationally inferable, if not obviously drawn, from the letter
or purpose of the collective bargaining agreement.” Executone Info. Sys., Inc. v.
Davis, 26 F.3d 1314, 1325 (5th Cir. 1994) (citation omitted).
      The arbitrator’s decision is consistent with “our expansive reading of the
‘essence’ test.” Id. When he issued the February award, the arbitrator relied

upon the language in the parties’ agreement, situating his decision and his
interpretation of his authority within the rules that governed their dispute
resolution process. Specifically, he held that Rule 40 of the AAA rules
permitted him to reconsider his previous decision and issue a substitute
opinion. In their CBA, the parties agreed that they would be bound by the AAA
rules. When a CBA explicitly refers to the AAA rules, those rules become
“incorporated” into the agreement between the parties. See Petrofac, Inc. v.
DynMcDermott Petroleum Operations Co., 687 F.3d 671, 675 (5th Cir. 2012).
      Rule 40 permits an arbitrator to modify his award under certain
circumstances. It provides, in relevant part:
      Within 20 days after the transmittal of an award, any party, upon
      notice to the other parties, may request the arbitrator, through the
      AAA, to correct any clerical, typographical, technical, or
      computational errors in the award. The arbitrator is not
      empowered to redetermine the merits of any claim already
      decided.
      The arbitrator found that he had committed a “technical error” when he
relied upon Union Exhibit 4, and he therefore held that Rule 40 allowed him
to vacate the January award and issue the February award. Though he did not
explain why his error was “technical” and why it did not violate Rule 40’s
prohibition   against    “redetermin[ing]   the   merits”   of   a   dispute,   his
interpretation is entitled to deference. Rule 47 of the AAA rules authorizes an
arbitrator to “interpret and apply [the AAA] rules insofar as they relate to the
arbitrator’s powers and duties.” This rule binds the parties to the arbitrator’s
interpretation as long as it is “within reasonable limits.” See Koch Oil, S.A. v.
Transocean Gulf Oil Co., 751 F.2d 551, 554 (2d Cir. 1985). Indeed, even where
“reasonable judges and arbitrators could interpret the AAA rules differently
from the way that [the arbitrator] did in this case,” that is “beside the point.”

dispute and bear on its final disposition are presumptively not for the judge,
but for an arbitrator, to decide.” (internal quotation marks and citation
omitted)).
        The terms “technical” and “merits” are not defined in the AAA Rules or
in the CBA. We have held that it “is the arbitrator’s charge” to “explicat[e]
broad CBA terms . . . when left undefined by [the] contract.” Albemarle Corp.
v. United Steel Workers ex rel. AOWU Local 103, 703 F.3d 821, 826 (5th Cir.
2013)    (citation   omitted).   When    evaluating    whether    an   arbitrator’s
interpretation of a CBA withstands scrutiny, it is not our role to determine
whether the arbitrator’s interpretation is correct. “[T]he sole question [before]
us is whether the arbitrator (even arguably) interpreted the parties’ contract,
not whether he got its meaning right or wrong.” Oxford Health, 569 U.S. at
569. Though an arbitrator’s decision must be vacated if it is completely
disconnected from the language of a CBA, an award may not be overturned
because the arbitrator’s reasoning is lacking. See id. at 571. Indeed, “among
the powers of an arbitrator is the power to interpret the written word, and this
implies the power to err; an award need not be correct to be enforceable.”
Trustmark Ins. Co. v. John Hancock Life Ins. Co. (U.S.A.), 631 F.3d 869, 874
(7th Cir. 2011) (citation omitted); see also Misco, 484 U.S. at 38 (“Courts . . . do
not sit to hear claims of factual or legal error by an arbitrator as an appellate
court does in reviewing decisions of lower courts.” (emphasis added)).
        Here, the arbitrator’s determination that he had committed a “technical”
error was an arguable interpretation of the contract. Though the arbitrator did
not explain his reasoning, “[i]t has long been settled that arbitrators are not
required to disclose or explain the reasons underlying an award.” Antwine v.
Prudential Bache Sec., Inc., 899 F.2d 410, 412 (5th Cir. 1990); see also United
Steelworkers of Am., 363 U.S. at 598. We can discern a possible rationale from

the arbitrator’s actions, demonstrating that his decision “must stand.” See
Oxford Health, 569 U.S. at 569 (“[A]n arbitral decision even arguably
construing or applying the contract must stand, regardless of a court’s views of
its (de)merits.” (internal quotation marks and citation omitted)). As the
Company argues, the arbitrator’s correction did not alter the “merits
framework from his first award.” The February award was consistent with the
arbitrator’s earlier reasoning, in which he had stated that he would have found
in favor of the Company if not for his reliance on Union Exhibit 4. When the
arbitrator concluded that it was technically erroneous for him to rely on Union
Exhibit 4, his February award retained the same framework as his earlier
award. Given the arbitrator’s broad powers under the AAA rules, we cannot
say that this interpretation of the undefined terms in the CBA “was so
unfounded in reason and fact, so unconnected with the wording and purpose of
the collective bargaining agreement as to manifest an infidelity to the
obligation of an arbitrator.” Executone, 26 F.3d at 1325 (internal quotation
marks and citation omitted).
      To support its position, CWA relies upon a set of cases in which we have
vacated an arbitrator’s decision because it ignored a clear term in a contract—
a defect that does not exist here. See, e.g., Hous. Lighting & Power Co. v. Int’l
Bhd. of Elec. Workers, Local Union No. 66, 71 F.3d 179, 184 (5th Cir. 1995)
(holding that arbitrator exceeded his authority where he conducted de novo
review of employee’s qualifications, even though this was prohibited by the
CBA); Delta Queen Steamboat Co. v. District 2 Marine Eng’rs Beneficial Assoc.,
889 F.2d 599, 604 (5th Cir. 1989) (holding that arbitrator exceeded his
authority where he ignored the definition of “proper cause” for employee
discipline in the parties’ CBA). Unlike these cases, the arbitrator here did not
ignore the language of Rule 40 or any other relevant term in the parties’

agreement. 3 To the contrary, he cited Rule 40, classified his error as a
“technical” one capable of correction, and held that his correction did not
violate Rule 40, notwithstanding the Union’s argument that he was “re-
determin[ing] the merits” of CWA’s claim against the Company. Even if the
arbitrator made a mistake in reaching his conclusion, “[t]he potential for . . .
mistakes is the price of agreeing to arbitration. . . . The arbitrator’s
construction holds, however good, bad, or ugly.” Oxford Health, 569 U.S. at
572–73; see also Manville, 831 F.2d at 74 (“The parties bargained for an
arbitrator who would determine facts and interpret the contract; there is no
injustice in holding them to this bargain.” (citation omitted)).
       This conclusion is further supported by our decision in Rain CII Carbon,
LLC v. Conoco-Phillips Company. In that case, the arbitrator initially awarded
a judgment of nearly $18 million to Rain, a purchaser of products sold by
Conoco. 674 F.3d at 471. However, the arbitrator’s award also included two
errant sentences that complicated this result, suggesting that Rain owed
money to Conoco, and that there was additional interest—exceeding
$200,000—that Conoco owed to Rain. See id. The combination of these
inconsistent statements led to uncertainty regarding the final award. See id.
After Rain filed a motion for clarification, the arbitrator classified the inclusion



       3 CWA argues that the arbitrator’s actions ignored the “finality” provision in the
parties’ CBA and the common law doctrine of functus officio. This argument misapprehends
the purpose of Rule 40. While it is true that the doctrine of functus officio “bars [the]
arbitrator from revisiting the merits of an award once the award has been issued,” Brown v.
Witco Corp., 340 F.3d 209, 218 (5th Cir. 2003 (citation omitted)), Rule 40 “essentially codifies
the common law doctrine of functus officio,” Int’l Bhd. of Elec. Workers, Local Union 824 v.
Verizon Fla., LLC, 803 F.3d 1241, 1248 (11th Cir. 2015) (citation omitted). Though the CBA
provided that the decision of an arbitrator “shall be final,” the CBA also authorized the
arbitrator to reconsider his decision as long as it complied with Rule 40. Given the
interlocking nature of these provisions, CWA’s argument that the arbitrator violated the
doctrine is a restatement of its argument that the arbitrator violated Rule 40—not an
additional basis for relief. Because the arbitrator did not ignore Rule 40 in issuing his
decision, he also did not ignore the CBA’s finality provision or the functus officio doctrine.

of these sentences as a “clerical error[].” Id. The corrected award retained the
nearly $18 million judgment but removed any additional information
regarding interest or off-set fees. Id.
      Like the Company, Conoco objected to the arbitrator’s interpretation of
his authority under the parties’ CBA. It argued that the initial inclusion of
those two errant sentences was actually intentional and “not a clerical error.”
See id. at 473. We disagreed and affirmed the district court’s confirmation of
the arbitrator’s second award. See id. at 474. We held that the arbitrator was
empowered to remove these sentences under the AAA Rules and rejected
Conoco’s attempt to classify the arbitrator’s actions as improper. Id. at 473–74.
In doing so, we observed that “Conoco has cited to no case holding that an
arbitrator’s correction of an award for clerical errors was not genuine or
credible.” Id. at 473.
      Rain CII confirms that our deferential standard of review requires us to
affirm an arbitrator’s modified decision as long as the arbitrator’s actions relied
on a reasonable interpretation of the parties’ agreement. Because the
arbitrator in Rain CII classified his error as “clerical,” that classification was
entitled to deference unless there was reason to believe that the arbitrator’s
classification was “not genuine or credible.” Id.; see also Martel v. Ensco
Offshore Co., 449 F. App’x 351, 352–56 (5th Cir. 2011) (affirming the correction

declaring certain language in an award to be a clerical error must be upheld .

was somehow improper.”).

      CWA distinguishes Rain CII by arguing that the arbitrator’s
modification resulted in a minor numerical adjustment—not a new finding of
liability. It is true that the arbitrator’s actions in this case go a step beyond
altering the amount of a money judgment, see Martel, 449 F. App’x at 354, or
deleting stray text from an arbitration award, see Rain CII, 674 F.3d at 473.
But we have never measured an arbitrator’s powers by the magnitude of the
change created by the arbitrator’s corrections. Instead, our decision in Rain
CII acknowledged the extreme deference afforded to an arbitrator’s
determination that his earlier error is capable of correction under the parties’
agreement. See id. (“Conoco has cited to no case holding that an arbitrator’s
correction of an award for clerical errors was not genuine or credible.”); see also
AP Seating, 2014 WL 3420805, at *3 (upholding the arbitration panel’s
determination that it had committed a “clerical error” because of the
“extraordinary level of deference afforded to arbitration awards”). The
arbitrator’s actions here—which stemmed from his interpretation of Rule 40—
fit within this framework, and are therefore entitled to deference.
      We are similarly unpersuaded by CWA’s citation to two out-of-circuit
cases: International Brotherhood of Electrical Workers, Local Union 824 v.
Verizon Fla., LLC, 803 F.3d 1241 (11th Cir. 2015) [hereinafter IBEW], and
Lindland v. United States Wrestling Association, Inc., 227 F.3d 1000 (7th Cir.
2000). In those cases, the Eleventh Circuit and the Seventh Circuit refused to
confirm modified arbitration decisions, holding that the arbitrators had
exceeded their powers when they issued the new decisions. IBEW, 803 F.3d at
1251; Lindland, 227 F.3d at 1004. In IBEW, the arbitrator justified his actions
under a Florida statute that authorized a court—not an arbitrator—to modify
a previously-issued decision. IBEW, 803 F.3d at 1245, 1250 n.12. The
arbitrator made no attempt to justify his actions under Rule 40 or to classify
his earlier error as “technical” or “clerical.” Id. Likewise, in Lindland, the
                                        12

Seventh Circuit held that an arbitrator who ignored “the contracts and other
rules” that governed the parties’ arbitration agreement exceeded his authority
under the agreement. 227 F.3d at 1004 (citation omitted). The arbitrator in
Lindland “thr[ew] aside [the AAA] rules” entirely, “implement[ing] his own
brand of industrial justice” and “overstep[ping] his powers.” Id. (internal
quotation marks and citations omitted). The opinion noted that this was not
an instance in which an arbitrator had erred in his interpretation of the
parties’ agreement; instead, the arbitrator in Lindland completely ignored the
rules that guided the parties’ decision-making process, and he therefore
strayed from his obligations under the parties’ CBA. See id. (“Arbitrator
Campbell did not misinterpret [the AAA Rules]; he decided to ignore [them]
utterly.”).
      In this case, the arbitrator grounded his modification within the rules
that governed the parties’ agreement. Though his interpretation of his powers
is debatable, “the question for a judge is not whether the arbitrator construed
the parties’ contract correctly, but whether he construed it at all.” Oxford
Health, 569 U.S. at 573. Because the February award stemmed from a
colorable interpretation of the parties’ CBA, the arbitrator drew the “essence”
of his decision from the parties’ agreement, and he did not exceed his authority.
See Misco, 484 U.S. at 38; Executone, 26 F.3d at 1325.
                                      IV.
      For the foregoing reasons, the judgment of the district court is
AFFIRMED.
