Before BRISCOE, BARRETT, and MURPHY, Circuit Judges.

MURPHY, Circuit Judge.

In this appeal, Kennecott Utah Copper Corporation seeks to overcome one

of the most demanding standards in American law: that defining when a court

may vacate a labor-arbitration award. Kennecott appeals the district court’s

refusal to do so. The arbitrator issued an award upholding a grievance which

challenged a Kennecott rule that employees must report 20 minutes before their

shift to be transported to their work sites. After the arbitrator had issued the

award, a union representative contacted him ex parte. The arbitrator then sent the

parties a letter for the stated purpose of clarifying the award. Kennecott insists

that the letter was not a clarification, but a second award.

Kennecott attacks the arbitrator’s decision on four grounds: the grievance

was untimely; the award on the merits nullified and added to the contract’s plain

language; the arbitrator was functus officio, i.e., without further authority, after

issuing the first award and could not issue a new one; and, even if the letter came

within the clarification exception to the functus officio rule, the ex parte contacts

invalidate it. This court has jurisdiction under 28 U.S.C. § 1291 and AFFIRMS.

I. FACTS AND PROCEEDINGS

A. The Agreements

 Kennecott and the Union were parties to two collective bargaining

agreements (CBAs). One was a multi-site master agreement (MA), and the other

a site-specific supplemental agreement (SA). These CBAs ran from 1993 to 1996. 

The parties concur that the SA controls in case of any conflict or inconsistency,

and that the CBAs required workers to grieve disputes within fifteen days of the

incident at issue.

Two clauses, one from the MA and one from the SA, govern the merits. 

They provide in general that Kennecott will not pay for travel time to work sites;

that company-provided transportation to the sites will leave 15 minutes before

shifts start; and that, when employees report and work before their shifts,

Kennecott will pay them 20 minutes at a rate and a half. In particular, Article

11.E of the MA says that 

1. All employees will be at their work station and ready for work at

the start of their scheduled shift. . . . Time used in . . . travel to

and from the work station . . . will not be considered as time

worked and will not be compensated . . . .

2. The Company will [transport] employees to their . . . work

locations . . . . Transportation will leave designated points at

fifteen (15) minutes prior to shift starting time to deliver

employees to their work locations to relieve employees on shift. 

Employees transported back . . . will receive pay for all time spent

traveling in excess of fifteen (15) minutes after shift ending time

. . . .
-4-

The SA says that, “[i]n compensation for extended average work time . . .

employees designated by the Company who report and work prior to shift will be

paid 20 minutes at a rate and one half for each regularly scheduled work shift.”

Under prior CBAs, Kennecott paid for travel time to and from worksites. 

The 1986 CBA eliminated pay for travel to, but kept it for travel from, worksites. 

In the 1990 negotiations, Kennecott refused to resume pay for travel to the

worksite. As a compromise, it agreed to pay for the “variety of preparatory work

requirements” that precede a shift. Workers from the oncoming shift perform

those tasks before their shift begins so that they can replace the prior shift without

halting production.

B. The Dispute

After 1990, the arbitrator found, Kennecott sporadically announced that

employees must board vans 20 minutes before their shifts. Each time, employees

would protest, and the company would withdraw or not enforce the rule. In

summer 1994, however, the company disciplined an employee for not boarding a

van 20 minutes before his shift. This was the first instance of such discipline.

The union then filed a grievance. It noted, as Kennecott stresses, that the

“off and on” announcements of a 20-minute departure-time rule “ha[d] been going

on for four years, 1 month and 3 days.” The grievance requested back-pay for 4

years’ worth of the 5-minute increments by which Kennecott had required
-5-

employees to report early for transportation. The parties ultimately asked

arbitrator Garth Mangum to decide (1) whether the union had timely filed the

grievance, and (2) if so, whether Kennecott was violating the CBA “by paying

employees time and one-half for 20 minutes and requiring employees to [board]

vans at 20 minutes before the shift starting hour? If so, what is the remedy?”

While the parties awaited a chance to argue the grievance before an

arbitrator, they negotiated and signed new CBAs, which took effect in late 1996. 

The new CBAs are not in the record, but the parties seem to agree that they

include provisions identical to the disputed ones from the 1993 agreements. 

C. The Award

The parties argued the grievance before Mangum in early 1997, and he

issued a written decision on May 5, 1997. He found the grievance timely. On the

merits, he ruled that the CBA barred Kennecott from requiring employees to

board vans more than 15 minutes before a shift. He reasoned that the MA’s

“Transportation will leave . . . 15 minutes prior to shift” language was

controlling, because nothing in the SA “specif[ies] that [it] in any way modifies,

replaces, or supersedes” that clause. He then addressed the SA’s provision that

“employees . . . who report and work prior to the shift will be paid 20 minutes.” 

That passage, he noted, cannot be read to provide travel pay, as all parties

concurred that Kennecott had never agreed to reinstate such pay. Mangum
-6-

concluded, however, that the SA does “compensate the employees for showing up

for transportation to and beginning of activities long enough before the start of

each shift” to avoid halting production. He further concluded that the provision

does not, by mandating compensation of “20 minutes[’]” pay, affect the question

how many minutes before a shift Kennecott may require employees to report for

transportation to work sites: 

[The SA] does not specify any time of transportation departure as a

requirement for receipt of the added compensation. Why 20 minutes

time and one-half compensation, rather than 15 minutes or some

other pay period was chosen, is undoubtedly lost among the

compromises inherent in bargaining.

Mangum held that the two clauses are not inconsistent and that the parties must

adhere to both until they expired or the parties agreed to change them. 

“Requiring departure from designated reporting points prior to 15 minutes before

shift starting times,” he concluded, “is a violation of the [CBA].” He ordered as a

remedy that “[a]ny employees penalized by such requirement are to be made

whole immediately.” In explaining what he meant by making employees whole,

he noted only his “understanding that only warning notices have been thus far

issued,” and ordered Kennecott to rescind any such warnings.

D. The Ex Parte Contacts and the Clarification Letter

Soon thereafter, a union representative named Holland phoned Mangum ex

parte, either asking him or leaving a message asking him to include Holland in
-7-

any phone conversation initiated by Kennecott. Holland then suggested to

Kennecott that the parties ask Mangum to clarify whether he had meant to award

backpay; Kennecott declined. Holland then sent Mangum an ex parte letter on

May 12 seeking clarification on four points. He then “outlined” the four points,

in his words, or, in Kennecott’s view, argued them. Holland devoted the longest,

most argumentative passage of his letter to explaining why the union believed that

the award had included backpay, and urging Mangum to clarify that it had.

Mangum thought Holland’s request for clarification had been bilateral. 

Without contacting Kennecott, he responded on May 13 with a letter to both

parties. “Upon rereading my decision,” his letter began, “I can see the

possibilities for misinterpretation and hereby clarify that decision.” After briefly

summarizing his timeliness and merits rulings, he devoted a long paragraph to

explaining why he had not meant to award backpay. He then reiterated that

“[b]oth the [MA] and the [SA] provisions in question are valid and must be

obeyed. Management is to cease and desist its efforts to substitute any other

practice for the duration of this agreement.” 

E. Proceedings in District Court

Kennecott filed a complaint in the District of Utah seeking an order

vacating the award; the Union counterclaimed, seeking an order enforcing the
-8-

award. District Judge Campbell resolved the case by ruling orally after hearing

argument on cross-motions for summary judgment. 

The court readily concluded that the award drew its essence from the CBA:

“[t]he bulk of Kennecott’s arguments [comprise] simply an attempt to reargue the

merits.” The court held that the arbitrator had not made any “second award,”

because the May 13 letter was “either a clarification or a [completion of] the May

5th award.” The court also found no affirmative misconduct by Mangum, and no

evidence that the undisputedly ex parte contacts had harmed Kennecott. Finally,

the court held that the arbitrator had jurisdiction to decide the timeliness dispute,

and upheld his resolution. After orally explaining her reasoning at some length,

Judge Campbell issued a brief written order granting summary judgment, which

incorporated by reference her oral ruling.

II. DISCUSSION

A. Mootness

The CBAs under which this dispute arose expired in 1996, and the

arbitrator’s award specified that the clause which he found controlling “will

continue in force until either expired or bilaterally changed.” That clause had

already expired, along with the rest of the CBA, when the arbitrator issued his

award in 1997. The award nonetheless quoted and referred only to the expired

1993 CBAs, not the corresponding clauses in the extant 1996 CBAs. The parties
1The only reference to the 1996 agreements apparent in the severalhundred-page record is the Union’s assertion in its counterclaim that it and

Kennecott are parties to a CBA which succeeded the 1993 CBA and took effect in

October 1996. The Union noted only that the 1996 Agreement made final and

binding an arbitrator’s decision rendered pursuant to it. Kennecott admitted

without elaboration these terse allegations.

-9-

attached only the expired 1993 agreements to their filings in district court and,

with two brief exceptions, referred only to those agreements in their arguments to

that court and on appeal.1

This dispute nonetheless remains live, and satisfies the “case or

controversy” requirement of Article III. Part of the remedy ordered was that

“[a]ny employees penalized by such requirement are to be made whole” by

Kennecott’s rescinding any warning notices for failure to report for transportation

over 15 minutes before a shift. That provision for retrospective relief in the

original award plainly saves the disputes regarding the original award’s validity

from mootness.

The clarification letter did not affect that retrospective part of the award. 

Because it clarified and/or completed the award’s provision of prospective relief,

however, the disputes about its validity also remain live. The validity of the

award’s prospective provisions will significantly affect, as a practical matter, the

parties’ ongoing bargaining relationship. The core question in mootness inquiry

is whether “granting a present determination of the issues offered . . . will have
2Because this court concludes that the practical effect of the award’s

prospective provisions saves from mootness those parts of the controversy

concerning the clarification letter, it is unnecessary to determine what binding

legal effect, if any, the prospective relief in the arbitrator’s interpretation of the

1993 CBA has under the current or future CBAs.

-10-

some effect in the real world.” 13A Charles A. Wright et al., Federal Practice &

Procedure § 3533.1, at 226 (2d ed. 1984); see, e.g., New Mexico Env’t Dep’t v.

Foulston (In re L.F. Jennings Oil Co.), 4 F.3d 887, 889 (10th Cir. 1993) (finding

case moot because resolution “would have no practical significance”). In cases

arising from collective-bargaining relationships, courts have been aggressive in

determining that a dispute remains live because the disputed issue continues to

shape the parties’ periodic bargaining or day-to-day interaction. See, e.g.,

Jacksonville Bulk Terminals, Inc. v. International Longshoremen’s Ass’n, 457

U.S. 702, 704 n.1 (1982); Super Tire Eng’g Co. v. McCorkle, 416 U.S. 115,

121–25 (1974); International Bhd. of Teamsters v. Southwest Airlines Co., 875

F.2d 1129, 1132–33 (5th Cir. 1989) (en banc) (discussing courts’ readiness to

find, in labor cases involving “lapsed contracts,” that dispute affects ongoing

relations). In this case, as noted above, clauses in the current CBA recapitulate

verbatim the clauses in the 1993 CBA interpreted by the award. An order

enforcing the award, and the award itself, will thus at a minimum have persuasive

value and practical effect in any future dispute about those clauses.2
-11-

B. Standards of Review

This court reviews a summary judgment in a labor-arbitration case de novo.

Judicial review of labor-arbitration awards, however, “is among the narrowest

known to the law.” Champion Boxed Beef v. Local No. 7, 24 F.3d 86, 87 (10th

Cir. 1994). “The arbitrator’s factual findings are beyond review, and, so long as

the arbitrator does not ignore the plain language of the [CBA], so is his

interpretation of the contract.” Id. “[A]s long as the arbitrator is even arguably

construing or applying the contract and acting within the scope of his authority,

that a court is convinced he committed serious error does not suffice to overturn

his decision.” United Paperworkers Int’l Union v. Misco, Inc., 484 U.S. 29, 38

(1987).

C. Timeliness

1. Standard of Review

It is less clear, however, what standard governs review of the arbitrator’s

ruling on timeliness. This court’s precedents are in tension on that issue. We

need not resolve the tension in this case, however, because Kennecott has waived

any right to less deferential review of the arbitrator’s decision on timeliness by

agreeing to submit that issue to the arbitrator.

Urging this court to review the timeliness ruling nondeferentially,

Kennecott quotes our holding in Barnard v. Commercial Carriers, Inc. that the
-12-

timeliness of a grievance was a “jurisdictional requirement” under the CBA at

issue. 863 F.2d 694, 698 (10th Cir. 1988); cf. id. at 699–700 (Seymour, J.,

concurring) (declining to join “jurisdictional requirement” holding). The

Barnard majority did not specify the effect of the time limit’s “jurisdictional”

status on the standard of review, but its review of the arbitrator’s resolution of

that issue was not consistent with the very deferential standard for review of an

award’s merits. See id. at 697–98. In a pre-Barnard opinion, however, this court

held that “federal courts are to give even greater deference to an arbitrator’s

decision on matters of procedure . . . . The Supreme Court has stated quite

plainly that matters of procedure lie solely within the discretion of the arbitrator.” 

United Steelworkers of America v. Ideal Cement Co., 762 F.2d 837, 841 (10th Cir.

1985) (citing John Wiley & Sons v. Livingston, 376 U.S. 543, 557 (1964)). Two

months later, we held that a dispute over a clear failure to comply with a strictly

worded time limit in a grievance clause was arbitrable. See Denhardt v.

Trailways, Inc., 767 F.2d 687, 688–89 (10th Cir. 1985) (holding that time-limit

provision is “for the arbitrator alone to apply”).

This case does not require this court to determine whether Barnard created

an exception to the established rule of Ideal Cement and Denhardt, or whether it

was a subsequent deviation from that established rule, and thus created an intracircuit conflict. Cf. Morrison Knudsen Corp. v. Fireman’s Fund Ins. Co., 175
-13-

F.3d 1221, 1240 (10th Cir. 1999) (discussing such conflicts). Even if Barnard

did create an exception to the Wiley rule, this case does not fall within that

exception. The grievance in Barnard concerned seniority dates, and the CBA

specified that such dates, unless timely challenged, “‘shall be deemed correct.’” 

863 F.3d at 698. The CBA in this case does not specify the consequences of

filing a grievance late. More importantly, the employee who was harmed by the

untimely grievance in Barnard had never agreed to submit the question of

timeliness to an arbitrator instead of a court. See id. That employee, indeed, had

not even known of the grievance, which was filed by another employee. See id.

Kennecott, by contrast, expressly agreed to submit to arbitration the timeliness

dispute in this case, and argued its position to the arbitrator. Several circuits have

held that, if a party submits a question of procedural arbitrability to an arbitrator,

a court will not later review the issue de novo, but will instead defer to the

arbitrator’s resolution in the same way it defers to his or her ruling on the merits. 

See, e.g., Interstate Brands Corp. v. Chauffeurs, Teamsters, Warehousemen &

Helpers Local U. No. 133, 909 F.2d 885, 890 (6th Cir. 1990); George Day Constr.

Co. v. United Bhd. of Carpenters & Joiners, 722 F.2d 1471, 1476 (9th Cir. 1984);

United Steelworkers of Am. v. American Smelting & Refining Corp., 648 F.2d

863, 866–67 (3rd Cir. 1981). The Supreme Court recently set such a rule in a
3The Court was interpreting the Federal Arbitration Act, 9 U.S.C. § 1–16,

but there is no apparent reason why its conclusion should not apply equally to

review of a labor-arbitration award. Cf. Misco, 484 U.S. at 40 n.9 (using Federal

Arbitration Act as source of principles for federal common law of labor

arbitration).

-14-

commercial-arbitration case. See First Options of Chicago, Inc. v. Kaplan, 514

U.S. 938 (1995). A unanimous Court found it “fairly simple” to conclude that 

[j]ust as the arbitrability of the merits of a dispute depends upon

whether the parties agreed to arbitrate that dispute, so the question

‘who has the primary power to decide arbitrability’ turns upon what

the parties agreed about that matter. Did the parties agree to submit

the arbitrability question itself to arbitration? If so, then the court’s

standard for reviewing the arbitrator’s decision about that matter

should not differ from the standard courts apply when they review

any other matter that parties have agreed to arbitrate.

Id. at 943.3

This court readily concludes that such a rule should govern review of laborarbitration awards. Even assuming timeliness was a jurisdictional issue in this

case, Kennecott waived any right to de novo judicial review of that issue by

voluntarily submitting it to arbitration. Accordingly, as in our review of an

award’s merits, we will accept without review the arbitrator’s factual findings

bearing on timeliness. See Champion Boxed Beef, 24 F.3d at 87. We will review

his ruling on timeliness to determine whether, in deciding that issue, he was

“‘even arguably construing or applying the contract.’” International Bhd. of Elec.

Wkrs., Local U. No. 611 v. Public Serv. Co. of N.M., 980 F.2d 616, 618–19 (10th
-15-

Cir. 1992) (quoting Misco, 484 U.S. at 38)). Such review serves only to ensure

that any dubious interpretation or application of a CBA’s time limits was at worst

a “serious error,” and not evidence that the arbitrator completely disregarded the

CBA in order to “dispense his own brand of industrial justice.” United

Steelworkers v. Enterprise Wheel & Car Corp., 363 U.S. 593, 597 (1960).

2. Timeliness

The arbitrator found that, while the company sporadically announced a 20-

minute-report-time policy over a four-year period, it backed down each time

employees protested, until in August 1994 it warned an employee in writing for

failing to board a van over 15 minutes before a shift. The arbitrator then drew a

legal conclusion that 

[t]he instigating cause of a grievance is when an employee . . .

believes that [his or her] rights under the [CBA] have been violated. 

That occurred in this case when the Company’s interpretation of the

1990 changes was first enforced in application to one or more

specific employees. . . . [T]hat first occurred in August 1994 and was

timely grieved.

The CBA requires employees to submit grievances within 15 days “of the

incident giving rise to the grievance or of notice or knowledge of such incident, if

later.” Mangum’s award did not expressly find whether, during the four years

before the grievance, employees ever reported for transportation 20 minutes early;

he only said that “[e]mployees . . . would protest that requirement and it would
-16-

either not be enforced or would be withdrawn.” Mangum’s May 13 letter,

however, strongly implied that at least some employees did report 20 minutes

early some times: “It was my conclusion that it would be impossible to determine

which and how many employees would have been on those vans for how many

minutes prior to the contractual 15[-]minute[-]prior departure. Therefore, I

attempted no remedy for those additional minutes . . . .” And as Kennecott

stresses, the grievance itself also strongly suggests that at least some employees

did report for transport more than 15 minutes before their shifts in 1990–94. 

In finding that Kennecott consistently withdrew or did not enforce the 20-

minute rule, and ruling that there was no grievable “incident” until it disciplined

an employee for refusing to obey that rule, Mangum did one of two things. He

may have simply ignored, in making his factual findings bearing on timeliness,

the evidence that the rule did function for some periods of time. This possibility,

which Kennecott stresses, is simply irrelevant to this court’s review. It does not

matter that an arbitrator’s express factual finding may have ignored or

contradicted some or even all of the evidence; his or her factual findings are

beyond review. See Champion Boxed Beef, 24 F.3d at 87. Alternatively, Mangum

may have made an implicit finding that the rule did function for some periods, but

then drawn a legal conclusion that, when an employer sporadically applies a rule

that violates a CBA, and some employees comply with the rule for some period or
-17-

periods of time, no incident triggers the time limit to file a grievance until an

employee refuses to follow the rule and the company disciplines him or her rather

than withdrawing the rule. Kennecott has not shown that the CBA expressly

forbade Mangum to use such a theory of when a grievance arises. He was at least

arguably applying or interpreting the contract in so reasoning. It is thus irrelevant

whether his interpretation of the provision is the best one, plausible, or even

erroneous. See Misco, 484 U.S. at 38. 

D. Merits

Kennecott argues that Mangum’s award does not draw its essence from the

CBA. Kennecott does not suggest any material other than the CBA from which

the award drew its essence. Thus, the only way that it can show that Mangum

failed to interpret and apply the CBA in good faith would be to show that his

award wholly ignores the agreement’s plain language. The gist of Kennecott’s

argument is that Mangum ignored the rule that the SA trumps the MA in case of

conflict and wrongly required Kennecott to pay for travel time.

As for the first argument, Mangum never said that the MA controls over the

SA in case of conflict. Nothing in his award suggests that he did not recognize

that the SA controls in case of conflict. He simply interpreted the MA and SA so

that, in his view, they did not conflict. The award says that the MA clause

providing that transportation will depart from designated points 15 minutes before
-18-

shifts begin “remains the governing language in the [MA].” The award then

specifies that neither that clause “nor the language of [the SA] specify that the

latter in any way modifies, replaces, or supersedes [that clause] of the [MA].” 

Mangum sought to apply both clauses, and did not deny that the SA would control

if they did conflict; this court cannot review the merits of the interpretation

whereby he reconciled the two contractual provisions.

Kennecott also argues that the award requires it to pay for travel time. 

Noting the contract’s language and bargaining history, Mangum concluded that

the CBA “specifically prohibit[s]” travel pay. At first blush, however, his award

seems to require just that. He banned Kennecott from making employees board

vans more than 15 minutes before their shift. The SA says that employees who

“report and work prior to the shift will be paid 20 minutes at a rate and one half.” 

To “work prior to the shift,” Kennecott notes, employees must get to the worksite

prior to the shift. Kennecott must pay them 20 minutes, but can only make them

report 15 minutes before their shift begins. If they spend those 15 minutes on a

van, Kennecott will have to pay for travel time. 

If that were the only way to read Mangum’s award, it would contravene the

rule barring travel-time pay. This court would then have to decide whether such

an interpretation was merely a serious error, or was instead “‘so unfounded in

reason and fact, so unconnected with the wording and purpose of the . . .
-19-

agreement as to ‘manifest an infidelity to the obligation of the arbitrator.’” 

Mistletoe Express Serv. v. Motor Expressmen’s Union, 566 F.2d 692, 694 (10th

Cir. 1977) (quoting Brotherhood of R.R. Trainmen v. Central of Ga. Ry. Co., 415

F.2d 403, 415 (5th Cir. 1969) (quoting Enterprise Wheel, 363 U.S. at 597)). 

That inquiry is unnecessary, however, for this court does not read the award

to require pay for travel time. The award bars Kennecott from making employees

report for transportation more than 15 minutes before a shift, and says that this

rule coexists with the rule of 20 minutes’ pay for “employees . . . who report and

work prior to the shift.” But the award does not expressly require pay for

employees who report 15 minutes early and spend all 15 minutes in travel. The

only employees for whom the award necessarily requires 20 minutes’ pay are

those who, despite boarding vans no more than 15 minutes before their shift, get

to the work site and in fact do some work before the shift starts.

This court agrees with Mangum that the 20-minutes’-pay rule contemplates

payment of a set amount of money regardless of how many minutes an employee

works before any given shift. It says that “in compensation for extended average

work-time, employees . . . who report and work prior to the shift will be paid 20

minutes at a rate and one-half for each . . . shift” (emphases added). It does not

say, “employees will be paid for however many minutes they work before each

shift at a rate and one-half.” The clause explains that the 20 minutes’ pay
4This Latin term for “task performed” is shorthand for the common-law rule

that, once an arbitrator has issued a final award and thus discharged his or her

office, that arbitrator lacks any continuing power to revise the award or issue a

new one. See, e.g., Black’s Law Dictionary 673 (6th ed. 1990); Glass, Molders,

etc. Union v. Excelsior Foundry Co., 56 F.3d 844, 845 (7th Cir. 1995).

-20-

compensates for “extended average work time,” not for the actual number of

minutes of extended work by a given worker on a given shift. It requires

Kennecott to provide 20 minutes’ pay “for each . . . shift.” The amount of pay is

plainly unrelated to the number of minutes worked before any particular shift.

The arbitrator was thus at least arguably construing or interpreting the CBA,

and not wholly ignoring it, when he concluded that the disputed clause allows

employees to board a van 15 minutes before a shift; reach their work site 2, 5, or

10 minutes before their shift; work for those 2, 5, or 10 minutes; and receive 20

minutes’ pay at a rate and one-half. Kennecott’s other arguments merely allege

error in Mangum’s interpretation of the CBA, and are irrelevant.

E. The Clarification Letter/Second Award

Kennecott challenges Mangum’s May 13 letter, which he called a

“clarification” but which Kennecott describes as a second award. (This opinion

will refer to the May 5 initial award as “the award” and the May 13 letter as “the

letter.”) Kennecott bases its challenge on two overlapping grounds: the functus

officio doctrine,4 and the ex parte character of the union’s request to Mangum to

clarify his initial award.
5

Judge Campbell concluded that the letter had either clarified the award’s

ambiguous reference to making employees whole, or completed the award by

addressing the unresolved issue of back-pay. Cf. International Bhd. of Teamsters

v. Silver State Disposal Serv., Inc., 109 F.3d 1409, 1411 (9th Cir. 1997) (noting

without concern that some courts have commingled clarification and completion

exceptions to functus officio rule).

-21-

This court has expressly reserved the question whether the body of federal

common law governing review of labor-arbitration awards incorporates the State

common-law doctrine of functus officio, which bars an arbitrator from altering or

adding to a final award. See Ideal Cement, 762 F.2d at 841 n.3; see also Glass,

Molders, etc. Union v. Excelsior Foundry Co., 56 F.3d 844, 846 (7th Cir. 1995)

(“The doctrine originated in the bad old days when judges were hostile to

arbitration and ingenious in hamstringing it . . . . Today, riddled with exceptions,

it is hanging on by its fingernails and whether it can even be said to exist in labor

arbitration is uncertain.”). Many courts have limited the doctrine to allow

arbitrators “to correct mistakes, complete awards which were not final, and clarify

ambiguities.” Ideal Cement, 762 F.2d at 841 n.3. The clarification exception to

the doctrine is well settled, and Mangum labeled his letter a clarification.5

Kennecott argues that the May 13 letter does not satisfy that exception, as it

added to or altered the original award instead of just clarifying it. It also argues

that Mangum, by responding to Holland’s ex parte contacts, denied it a chance to

be heard. Kennecott relies on a Third Circuit opinion deeming it “axiomatic that
-22-

a district court may vacate an award if a party to an arbitration proceeding has not

been given notice and opportunity to present arguments and evidence.” Teamsters

Local 312 v. Matlack, Inc., 118 F.3d 985, 995 (3rd Cir. 1997). Matlack, however,

only says that courts “may” vacate awards because of ex parte contacts. Id. at

995. Matlack and several opinions from other circuits plainly state or necessarily

imply a rule that ex parte contacts must have prejudiced the party resisting

enforcment of an arbitral award. See id. (adopting rule developed under Federal

Arbitration Act that court “has the power to vacate an arbitration award where an

arbitrator receives ex parte information to the prejudice of one of the parties”);

Excelsior Foundry, 56 F.3d at 846; M & A Elec. Power Coop. v. Local U. No.

702, Int’l Bhd. of Elec. Wkrs., 977 F.2d 1235, 1237–38 (8th Cir. 1992); see also,

e.g., Employers Ins. of Wausau v. National U. Fire Ins. Co. of Pittsburgh, 933

F.2d 1481, 1490–91 (9th Cir. 1991) (requiring prejudice to vacate commercial

arbitration award because of ex parte contacts, and citing similar commercialarbitration precedents). Because this court agrees that there is no rule of per se

nonenforcement upon a showing of ex parte contact, we must determine whether

Kennecott has shown prejudice. 

The prejudice inquiry effectively merges in this case with the functus officio

inquiry. The one undisputed purpose of Mangum’s letter was to clarify the

award’s ambiguity regarding back-pay. Kennecott plainly benefitted from that
6Kennecott also argues that the letter did not merely clarify the back-pay

issue, because Holland’s ex parte letter had argued four separate points. 

Holland’s letter, however, only seems to significantly argue the backpay issue; it

merely restates the arbitrator’s initial rulings on the other three issues it discusses. 

But even assuming that Holland did “argue” the other points, the relevant

question is not what the union argued, but whether Mangum’s letter responding to

those improper arguments altered or augmented the initial award, and thus

prejudiced Kennecott. 

-23-

clarification. Kennecott must therefore show that the letter did more than clarify

the back-pay issue in order either to place the letter outside the clarification

exception, or to show that Holland’s ex parte contacts prejudiced Kennecott. 

Accordingly, this court must determine if the letter added anything adverse to

Kennecott that the award had not already said or necessarily implied. 

Kennecott claims several differences between the letter and the award.6

 The

first is the letter’s allegedly new “cease and desist” order. While the words

“cease and desist” are new, this court agrees with the district court that the

substantive message they convey is merely the necessary implication of the

original award’s finding of a violation. This court is no more able than the

district court was to understand how Mangum could merely have intended the

award to note the violation, leaving Kennecott free to continue it until he “added”

in the letter a requirement that Kennecott cease and desist from said violation.

Kennecott suggests several other differences between the letter and the

award, but all are plainly illusory. Kennecott asserts that the letter, unlike the
-24-

award, deprives it of its “contractual right to ‘designate’ employees to ‘report and

work prior to the shift.’” This is simply untrue: the letter only prohibits

Kennecott from designating employees to report for transportation more than 15

minutes prior to their shift. It also claims that the award allowed it to require its

employees to report to work more than fifteen minutes before shift starting time if

it compensated the employees with 20 minutes’ pay, but that the letter altered this

rule by flatly banning Kennecott from requiring employees to report more than 15

minutes early. To the contrary, the award carefully explained that the reportingtime and pay provisions are separate, and unqualifiedly held that “[r]equiring

departure from designated reporting points prior to 15 minutes before shift

starting times is a violation of the [CBA].” It did not say “. . . unless the

company provides 20 minutes’ pay.” Nothing in the award supports Kennecott’s

reading. 

Kennecott also argues that the award only addressed “departure time,” while

the letter introduced the purportedly separate concept of “reporting time.” The

award, however, repeatedly refers interchangeably to the question of when

employees must arrive at the designated transport-departure point in terms of

“reporting” and “departure.” This is clear in the sentence, “Article 11 E 2 is a

reporting provision and continues to govern departure of transportation”

(emphases added). Kennecott argues, finally, that the letter imposed a new rule
-25-

that it may not “substitute any other practice for the duration of this agreement.” 

Kennecott suggests that this language limits its options more sharply than had the

award. But the “any other practice” language follows the sentence, “Both the

[MA] and [SA] provisions in question are valid and must be obeyed.” It does not

specify any particular practice which Kennecott may not alter, or limit

Kennecott’s freedom any more than the award.

Kennecott has thus failed to demonstrate that the letter augmented or altered

the award in any way other than clarifying that Mangum had not awarded

backpay. The letter thus fell within the clarification and/or completion exceptions

to the functus officio doctrine. The undisputedly improper ex parte contacts did

not prejudice Kennecott, and thus did not warrant a refusal to enforce the award. 

F. The Order’s Alleged Lack of Adequate Findings or Conclusions

Kennecott acknowledges that Federal Rule of Civil Procedure 52(a) makes

findings of fact and conclusions of law unnecessary in a summary judgment. See

Viernow v. Euripides Dev. Corp., 157 F.3d 85, 792 n.13 (10th Cir. 1998). It

nonetheless urges this court to set aside the judgment because the district court

allegedly failed to explain its reasoning in sufficient detail to permit review. This

argument borders on the frivolous. The court explained the reasoning for its

decision cogently and at some length in its comments from the bench after ruling

orally. The court then noted that it would “prepare a very brief order” granting
-26-

summary judgment, which it did. Kennecott seems to suggest that the court was

required to reproduce its reasoning in the written order, but it cites no authority

for that novel proposition. Cf. Gomez v. American Elec. Power Serv. Corp., 726

F.2d 649, 654 n.4 (10th Cir. 1984) (deeming findings and conclusions helpful for

purposes of review). The court’s oral comments plainly suffice to explain the

basis of its judgment and permit review thereof.

IV. CONCLUSION

Kennecott has not overcome the deferential standard for judicial review of

the merits of labor-arbitration awards. Nor has it shown that the timeliness, ex

parte, or functus officio issues compel this court to apply a less deferential

standard of review and deny enforcement. This court thus AFFIRMS the order

enforcing the award.
