               SELYA, Circuit Judge.                Arbitral awards are nearly

impervious to judicial oversight.                  See Advest, Inc. v. McCarthy,

914 F.2d 6, 8-9 (1st Cir. 1990) (describing exceptions); Maine

Cent. R.R. Co. v. Brotherhood of Maintenance of Way Employees,

873 F.2d 425, 428 (1st Cir. 1989) ("Judicial review of an

arbitration award is among the narrowest known in the law.").

Accordingly, disputes that are committed by contract to the

arbitral       process     almost    always        are   won    or    lost    before     the

arbitrator.          Successful         court      challenges        are   few     and   far

between.

               Undaunted by this bleak prospect, Local Union No. 42

(Local    42    or   the    union),      a   Teamsters         affiliate,        invited    a

federal district court to vacate a labor arbitrator's award in

favor of Supervalu, Inc. (Supervalu or the employer).                            The court

refused the invitation.             Because we agree that the arbitrator,

regardless of whether his decision was right or wrong, acted

within    the     realm     of    the    authority        vested      in     him   by    the

applicable collective bargaining agreement, we affirm.

I.   BACKGROUND

               Supervalu is a large wholesale grocer that operates a

regional       facility      in     Andover,        Massachusetts.               Local     42

represents all the warehouse workers and truck drivers at that

site.    The parties' current collective bargaining agreement (the


                                             -2-
CBA) took effect in May of 1994.           Among other things, the CBA

designates Local 42 as the exclusive bargaining agent for its

members, lays out wage rates for the multi-year period covered

by the pact (distinguishing, in the process, between "present"

and "new" full-time employees), and sets out guidelines for the

allocation of benefits.

            About two months before the CBA took effect, Supervalu

acquired the business of a competitor, Sweet Life Foods (SLF),

which operated a grocery warehouse in Northboro, Massachusetts.

As part of that transaction, Supervalu assumed the collective

bargaining agreement then in effect between SLF and Teamsters

Local 170 (which represented workers at the Northboro facility).

Supervalu    soon   decided   to    move   all   the   Northboro    work   to

Andover, transferring some of the crew and discharging the rest.

To that end, it commenced negotiations with Local 170 anent

transfer and severance terms, but failed to reach an accord.

            In August of 1994, Supervalu made a so-called "final

and best offer" to Local 170 in the form of a memorandum that,

among other things, laid out anticipated terms of engagement

(including    compensation)        for   those   workers   who     would   be

redirected to Andover.        Supervalu informed a representative of

Local 42 about the proposal (or so the arbitrator supportably

found), but it never bargained with Local 42 anent the terms and


                                     -3-
conditions of the transferees' employment.                      In all events,

neither Local 170 nor Local 42 ever formally accepted the offer.

Supervalu, acting unilaterally, nonetheless started shifting

workers from Northboro to Andover in late August and September.

Upon       reporting   for     duty      at    Andover,        the   transferees

automatically became members of Local 42.

              Supervalu applied the wage rate and conditions of

employment      specified     in   the    memorandum      to   the   transferred

workers.        Overall,     these    terms    were   a   compromise     between

treating them like veteran employees and treating them like

neophytes.1      This hermaphroditic status sowed the seeds for an

horrific harvest.

              The first poisonous plant bloomed when the union,

acting on the transferees' behalf, grieved the allocation of

bonus days (i.e., extra personal days), charging that under

Article 25 of the CBA the transferees' entitlement to bonus days

should be determined in light of their years of service with



       1
      To offer a few illustrations, the transferred workers were
treated like experienced hands in that they were exempted from
the 60-day probationary period for new hires imposed by Article
2 of the CBA and received credit toward vacation eligibility for
the time they had worked with SLF.     They were, however, paid
less than veteran workers (although their starting wage — $13.23
per hour — was    substantially above the minimum rate set for
beginners in the CBA), and their eligibility for bonus days was
calculated as if they had begun work on the date the CBA took
effect.

                                         -4-
SLF.   In mounting this challenge, the union brushed aside the

CBA's definition of seniority as "the period of employment with

[Supervalu]   in    the   work   covered   by   this   Agreement,    at    the

terminal (or terminals) within the jurisdiction of the Local,"

and posited that "years/service" — the critical integer in the

bonus days equation — was a broader term that could include

periods in the employ of SLF.       Supervalu rejected the grievance,

asserting that years of service, like seniority, had to be

calculated from     the date it hired an employee to work full time

at Andover.

          The parties submitted the case to arbitration.                   The

arbitrator, Greenbaum, observed that some workers who came to

the Andover facility from acquired companies had been permitted

to carry over years of service (as well as seniority).              She then

determined that, from and after 1989, the terms "years/service"

and "seniority" had developed distinct meanings.             Beginning at

that time, the CBA made provision for "casual employees," i.e.,

part-time workers hired, as needed, to toil in the Andover

warehouse,    and   those   employees,     collectively,    had     come   to

constitute the pool from which most new full-time workers were

recruited.    Arbitrator Greenbaum noted that when a casual worker

became a regular full-time employee, Supervalu figured his years

of service from his original date of hire as a casual employee,


                                    -5-
even though he accrued no seniority in respect to the time spent

in casual work.

           The arbitrator found additional support for the theory

that years of service and seniority were independent variables

in the differing uses of those terms within the four corners of

the CBA:

           A review of [the terms'] uses in the
           Agreement shows that where the intent is to
           provide an employee with a benefit that is
           non-competitive, i.e., does not impact on
           any other employee, such as bonus days and
           entitlement to vacation days, the parties
           used the synonymous terms of date of hire or
           years of service or length of service or
           "the period of employment with the Company"
           and "in the Company's employ" all meaning
           essentially the same thing.    In contrast,
           the term "seniority" is generally used where
           competitive rights are involved.     This is
           the   case  in   bidding   for   promotions,
           preferences    for    vacation    schedules,
           preference for work assignments, . . . .

She also found that this dichotomy characterized the treatment

of the transferees (at least to some degree), inasmuch as their

vacation   entitlement   —   a   non-competitive   benefit   —   was

determined in light of the years they had worked at SLF, while

preference in vacation scheduling — a competitive benefit — was

allocated strictly in accordance with seniority.

           Based on these facts, the arbitrator found that, as

used in the CBA, "years/service" was broader than "seniority"

and sometimes included work other than full-time Local 42 work

                                 -6-
at the Andover warehouse; and that the transferees' previous

service at SLF should have informed the calculation of their

bonus days.       The fact that the SLF transferees were not treated

generically       as   new    hires          (unlike      another      group     that    had

previously joined the work force from an acquired company)

contributed       heavily         to   her    conclusion       that       Supervalu      had

breached the CBA in computing the transferees' entitlement to

bonus days without regard to "years/service" (including time

spent at SLF).2

            The     battleground          then       shifted      to     wages    and,   in

particular, to Article 13 of the CBA (governing "minimum hourly

wages").      Article        13    sets      out    separate      wage    schedules      for

"present" and "new" full-time workers, and lists wage rates for

casual (part-time) workers in a separate chart.                          Both before and

after the CBA took effect, Supervalu's prevailing practice was

to   pay   former      casual      workers         who   became    regular       full-time

employees at the rate specified by the controlling CBA for new



      2
     Arbitrator Greenbaum found Supervalu's breach of the CBA
especially flagrant because it had allowed transferees to
receive bonus days as early as May 1995, even though they had
not yet been working at Andover for a full year.         In the
arbitrator's words, "[t]he Company created a fiction for them by
changing their date of hire from September or October 1994 to
May 1994 [when the CBA had taken effect], which certainly was
not in accordance with its agreement with Local 42."        This
approach both ignored the transferees' years of service at SLF
and defied the CBA's rules anent new hires.

                                             -7-
hires.   When Supervalu began to integrate SLF personnel into its

Andover work force, it paid them at a rate of $13.23/hr. — one

that fell somewhere between the rate for new recruits and the

rates applicable to present workers.

          Buoyed by Arbitrator Greenbaum's award, Local 42 filed

a second grievance.       This time, it argued that the starting

wages paid to erstwhile casual employees and SLF transferees

were too stingy and placed Supervalu in breach of Article 13.

The union asseverated that wages, like bonus days and vacation

eligibility,   were   a   non-competitive   benefit   and   should   be

determined by years of service, not seniority, in accordance

with Arbitrator Greenbaum's construct.        If this were so, the

union's thesis ran, workers who had accumulated years of service

could not properly be deemed "new," and Supervalu's praxis of

paying them differently than "present" employees transgressed

the CBA because Article 13 contained no classification for full-

time workers other than "new" and "present."

          This second grievance was heard by Arbitrator Cooper.

He adopted Arbitrator Greenbaum's extensive findings of fact and

acknowledged that Local 42 had never agreed to a specific wage

scale for the transferees.      The question for the transferees,

then, was whether the wages unilaterally imposed by the employer

breached the CBA.     Noting that Article 13's wage-rate provision


                                 -8-
did not state whether the wage progression limned thereby was to

be based upon "seniority" or "years/service," Arbitrator Cooper

concluded that the article was thus ambiguous as to whether the

transferees and former casual employees — who had accrued years

of service but no seniority — were to be regarded as "new" or

"present" workers for purposes germane to this article.                            The

arbitrator proceeded to explore the perceived ambiguity.

              He first examined the historical development of the

wage provisions.             Doing so revealed to his satisfaction that

paying       former    casual    workers    as     "present"      workers        (i.e.,

according to their original dates of hire) would create some

obvious anomalies.           For example, the CBA dictated that "all new,

full       time    employees"    would     reach    the    top    rate      in   their

classification          after    seven     years,    but,        on   the     union's

interpretation, some casual workers would receive the top rate

simultaneous          with    their   engagement      as    regular         full-time

employees, leapfrogging more senior members of Local 42 in the

process.3         The arbitrator expressed grave doubt that the parties




       3
     This would create a stark inequity in regard to workers who
had been recalled after forced layoffs. When reinstated, such
workers are paid at the rates they were earning when furloughed,
not at the current rates for "present" workers.        They are
nonetheless entitled, under Article 27 of the CBA, to a
preference over casual workers when positions open up.

                                         -9-
intended the CBA to produce such eccentric results "without a

single word in the [text]."

            Arbitrator Cooper also found that longstanding practice

suggested    that   the   parties    "did   not   consider   [a   casual

employee's] date of hire as the point for measuring his or her

progression on the salary scale."           In this vein, he observed

that the employer had paid former casual workers who became

regular full-time workers at the rate for "new" hires ever since

the casual employee category had been established in 1989.

Coupling this evidence of prior practice with the language of

the CBA, Arbitrator Cooper concluded that Supervalu had not

contravened the intention behind Article 13 by paying former

casual employees according to the schedule for new hires.4

            Arbitrator Cooper then turned to the issue of whether

the wages paid to workers transferring from SLF should have been

based on years of service or seniority.            He found that his

resolution of the earlier question — involving the entry-level

rate for former casual employees who converted to full-time

status — was decisive:


    4This aspect of the arbitral award is not before us.
Although the union's complaint prayed for vacation of the entire
award, its arguments before this court have dealt exclusively
with the rates paid to transferees.      We limit our analysis
accordingly and deem forfeited all arguments about the wages for
former casual employees. See Sheinkopf v. Stone, 927 F.2d 1259,
1263 (1st Cir. 1991).

                                    -10-
            Unless there is some compelling aspect of
            Article   13    which   demonstrates   that
            notwithstanding the narrow definition of
            "seniority," wages were to be determined by
            time in service including time spent with
            the Company at the former Sweet Life
            facility, the Union does not have a valid
            contractual claim.    Arbitrator Greenbaum
            relied upon the fact that for employees who
            served as casual employees and later became
            regular full-time employees, the Company
            counted their service time from their
            initial date of hire, not their seniority
            date, to measure their entitlement to bonus
            days. The opposite is true in the current
            case, the Company never counted from the
            date of hire to determine the appropriate
            wage rate for casual employees. Given this
            circumstance, Arbitrator Greenbaum's Award
            requires a different outcome.

Thus, Supervalu had not violated Article 13 of the CBA by

declining     to    pay   SLF   transferees    the   wages   guaranteed     to

"present" employees.

            In resolving the second grievance favorably to the

employer, the arbitrator gave short shrift to the union's claim

that Supervalu was in breach because it had paid the transferred

workers more than the wages stipulated in Article 13 for "new"

employees.     In his view, Article 13 established "only a minimum

wage   rate   and    therefore    if    the   Company   seeks   to   pay   the

employees more than is required, it is permitted to do so."                 He

bolstered this finding by noting the transferees' acquiescence

in the rates paid and concluding that "the general acquiescence

by the employees involved should be inferred to the Union."

                                       -11-
             Displeased with Arbitrator Cooper's award, Local 42

filed suit for vacation in the federal district court.                         See 29

U.S.C.   §    185.      After     weighing      cross-motions         for     summary

judgment,     the     court    determined       that   the    union's       jeremiad

amounted to no more than a litany of factual and legal errors

allegedly made by the arbitrator, and concluded that it lacked

authority     to     intercede.      Consequently,           it    granted     brevis

disposition in Supervalu's favor.               This appeal ensued.

II.   STANDARD OF REVIEW

             In an action to vacate an arbitral award, this court

reviews the district court's grant of summary judgment de novo,

applying     the     same     standard     as   did    that       tribunal.       See

Wheelabrator Envirotech Operating Servs. Inc. v. Massachusetts

Laborers Dist. Council Local 1144, 88 F.3d 40, 43 (1st Cir.

1996).     In this type of case, the district court's authority

(and, hence, our authority) is very tightly circumscribed:

             The courts are not authorized to reconsider
             the merits of an award even though the
             parties may allege that the award rests on
             errors of fact or on misinterpretation of
             the contract. . . .        As long as the
             arbitrator's award "draws its essence from
             the collective bargaining agreement," and is
             not merely "his own brand of industrial
             justice," the award is legitimate.

United Paperworkers Int'l Union v. Misco, Inc., 484 U.S. 29, 36

(1987) (quoting United Steelworkers v. Enterprise Wheel & Car


                                         -12-
Corp., 363 U.S. 593, 597 (1960)).         This standard has been

described in different ways over time.     See Advest, 914 F.2d at

9 (citing examples).    Whatever words are used, however, all the

formulations reflect the idea that a court ought not to vacate

an arbitral award "as long as the arbitrator is even arguably

construing or applying the contract and acting within the scope

of his authority."      Misco, 484 U.S. at 38; see also Labor

Relations Div. of Constr. Indus. v. Int'l Bhd. of Teamsters,

Local #379, 29 F.3d 742, 743 (1st Cir. 1994) (concluding that

"courts must resist the temptation to substitute their own

judgment about the most reasonable meaning of a labor contract

for that of the arbitrator and avoid the tendency to strike down

even   an    arbitrator's   erroneous   interpretation    of   such

contracts").

            In a case in which the arbitrator purports to interpret

the language of a collective bargaining agreement, a party who

seeks judicial review ordinarily must demonstrate that the award

is contrary to the plain language of the CBA and that the

arbitrator, heedless of the contract language, preferred instead

to write his own prescription for industrial justice.    See Kraft

Foods, Inc. v. Office & Prof'l Employees Int'l Union, Local

1295, 203 F.3d 98, 100 (1st Cir. 2000); Challenger Caribbean

Corp. v. Union General de Trabajadores, 903 F.2d 857, 861 (1st


                                -13-
Cir. 1990).        Put another way, a successful challenge to an

arbitral award in such circumstances necessitates a showing that

the award is "(1) unfounded in reason and fact; (2) based on

reasoning so palpably faulty that no judge, or group of judges,

ever    could    conceivably   have   made     such   a   ruling;    or   (3)

mistakenly based on a crucial assumption that is concededly a

non-fact."      Local 1445, United Food and Commercial Workers Int'l

Union v. Stop & Shop Cos., 776 F.2d 19, 21 (1st Cir. 1985).

III.    ANALYSIS

           Local 42 maintains that Arbitrator Cooper committed

four fundamental mistakes.       First, the union asserts that the

arbitrator       impermissibly   relied        upon   the     transferees'

acquiescence in regard to their wage rate (reliance which, in

the    union's    view,   contradicts    the    union's     status   as   the

transferees' exclusive bargaining representative in respect to

wages).    Second, the union contends that, whereas Article 13

created only two classifications of regular full-time employees,

the arbitrator took it upon himself to rewrite the agreement and

construct another category.       Third, the union charges that the

arbitrator departed from his proper province when he allowed

Supervalu to pay the transferees more than the minimum hourly

wage for new workers specified in the CBA.            Finally, the union




                                  -14-
raises a claim of procedural error.                   We find none of these four

arguments persuasive.

                                            A

            Local     42   calumnizes       the       arbitrator's    comment       that

"[w]hile the Union did not agree to [the transferees'] wage

rate, the general acquiescence by the employees involved should

be inferred to the Union."            The union claims that acquiescence

is    irrelevant,     and     that    the       arbitrator's       reliance    on     it

effectively     rewrote       the     CBA       and    frustrated     the     union's

prerogative as the exclusive negotiating agent for all the

employees      in    the    bargaining          unit     (including        those     who

transferred from SLF).          As a subset of this argument, the union

claims that glorifying the effect of acquiescence inserted into

the CBA a brand-new timeliness requirement for union grievances.

            This argument is a red herring.                   We do not agree with

the    union   that    Arbitrator          Cooper       premised     his    award     on

acquiescence.       As the passage quoted supra at 10 makes manifest,

the arbitrator understandably determined that "new," as used in

Article 13, must mean "without seniority" in order to make sense

of the overall payment scheme vis-à-vis former casual employees.

Based on this determination — one which the union does not

challenge,     see    supra    note    4    —    he    then   concluded     that     the

transferees (whom the union concedes had no seniority) likewise


                                       -15-
must       be   deemed   "new"    employees    for    purposes     of   the   wage

provision.5 This reasoning depended on the contract language and

the arbitrator's discernment of the parties' mutual intent.                      It

did not "ignore the plain language of the contract," Misco, 484

U.S. at 38, because "new" plausibly could mean "new to Local 42

and the Andover warehouse."               Nor did it depend in any way,

shape, or form on a finding of acquiescence.

                We hasten to add that Arbitrator Cooper's rendition of

the wage provision seems reasonable — especially since the

parties knew, when the CBA was signed, that the category of

"new"      employees     under   the   previous   CBA    had   been     deemed   to

include former casual employees for wage purposes.                    Indeed, the

only way to avoid the conclusion that he reached (after deciding

that "new" meant "without seniority") would have been to decide

that "new" had different meanings for different categories of

workers.        We cannot fault the arbitrator for his reluctance to

engage in that type of linguistic microsurgery.                   In all events,

what       counts   is   that    the   arbitrator's     reading    of   the   wage



       5
     Arbitrator Cooper was not precluded from reaching this
result by Arbitrator Greenbaum's conclusion that the parties
typically used years of service to quantify non-competitive
benefits. Earlier holdings of a previous arbitrator do not bind
a new arbitrator to read a collective bargaining agreement in a
way that he determines is contrary to the parties' intent. See
Boston Shipping Ass'n v. International Longshoremen's Ass'n, 659
F.2d 1, 3 n.4 (1st Cir. 1981).

                                        -16-
provision, right or wrong, had a plausible basis in the language

and structure of the CBA.            A reviewing court can go no further.

See Coastal Oil of New Engl., Inc. v. Teamsters Local A/W, 134

F.3d 466, 469 (1st Cir. 1998); Challenger Caribbean, 903 F.2d at

863-64.

              If more were needed — and we doubt that it is — we note

that       Local    42     wrests   the    arbitrator's            statements       about

acquiescence from their contextual moorings, thus distorting

their meaning.           Placing the remarks in context clarifies their

possible role in the decisional calculus.6                      Toward the beginning

of Arbitrator Cooper's discussion, he wrote that "[o]nce the

facts are determined, an arbitrator's first step is to look at

the    parties'         Agreement   and,       if    the   clear       and    unambiguous

language of that Agreement does not answer the question posed,

the parties' conduct should be used to help decipher their

intent."           He    then   seems     to        have   used    the       transferees'

acquiescence (and that of Local 42) to cast light upon the

parties' initial understanding that the transferees' wage rate

was    acceptable.           That   understanding           —     as   the     arbitrator

suggested in the very next sentence — could reflect that the



       6
     Neither the arbitrator's factual finding of acquiescence
nor his legal determination that acquiescence could be imputed
to the union are susceptible to review in this proceeding. See
Misco, 484 U.S. at 36, 38.

                                          -17-
union knew all along that the CBA established a minimum wage

rate and thus permitted the employer to pay more than the

minimum if it so desired.    Applying this original understanding

to what was done vis-à-vis the transferees lends support to his

holding.

           To be sure, the arbitrator's decision is not entirely

a model either of consistency or clarity.    But we do not review

arbitral decisions for style points, and the arbitrator's core

message — that the CBA, as drafted, permitted the employer

unilaterally to pay classes of employees more (but not less)

than the agreed minimum wage — comes through with sufficient

precision.    To cinch matters, although rational minds can differ

about whether the arbitrator accurately divined the parties'

intent, the standard of review does not allow an inquiring court

to second-guess the correctness of that determination.        See

Enterprise Wheel, 363 U.S. at 599; Labor Relations Div., 29 F.3d

at 745.      Nor does the arbitrator's use of acquiescence as

relevant evidence open the award to judicial nullification.

Even if his usage is susceptible to the union's charge that he

impermissibly read a timeliness provision into the CBA, "[a]

mere ambiguity in the opinion accompanying an award, which

permits the inference that the arbitrator may have exceeded his




                                -18-
authority, is not a reason for refusing to enforce the award."

Enterprise Wheel, 363 U.S. at 598.

            We add a postscript of sorts.       An arbitrator has no

duty   to    set    forth   the    reasons   underlying       his     award.

Consequently, a reviewing court may "uphold[] the arbitrator's

decision on grounds or reasoning not employed by the arbitrator

himself."     Labor Relations Div., 29 F.3d at 747.                 For that

reason, we see no problem in approving the instant decision

based on the arbitrator's plausible construction of the terms

"new" and "minimum hourly wages," without more.

                                     B

            This brings us to Local 42's contention that Arbitrator

Cooper arbitrarily engrafted a hybrid category of regular full-

time workers — transferees        — onto Article 13.    This contention,

too, stems from an insensitive reading of the arbitrator's

decision.    We explain briefly.

            The    arbitrator's   award,   whether     or   not   mistaken,

resulted directly from his interpretation of two terms set forth

in Article 13 of the CBA ("new" and "minimum hourly wages").              On

that basis, he determined that the employer was entitled as a

matter of contract to pay more (but not less) than the rates

listed as "minimum hourly wages."          This determination did not

create a third category of full-time employees.             Rather, under


                                   -19-
the arbitrator's plausible construction, the transferees were

members of the CBA's new-worker category who were being paid

more than the minimum wage, as the CBA permitted. 7                 Viewed in

this light, the arbitral decision did not amend the CBA, but,

rather, derived its essence from the CBA.          No more is exigible.8

See Misco, 484 U.S. at 36; Kraft Foods, 203 F.3d at 102, 103.

                                     C

           Local   42   makes   a    last-ditch    assertion        that   the

arbitrator exceeded his authority because "[n]othing in the

[CBA] provided Supervalu with the right to pay more than the

contractually stated terms without Local 42's agreement."                  In

its estimation, the CBA is not a "minimum standards contract,"

and thus deprives the employer of the freedom to pay more than

the stipulated wages.       This is the same whine — a protest

against   the   arbitrator's    construction      of   the   term    "minimum


    7We note in passing that, for much the same reason, the
higher wages did not contravene Article 9(C) (which barred
"attempt[s] to arrange other conditions [of employment] with any
of its employees than are set forth in this Agreement").
    8Although the workers who had been transferred from SLF did
not comprise a third category of regular full-time employees
within the meaning of Article 13 of the CBA, the separate
definitions of "years/service" and "seniority" described by
Arbitrator Greenbaum plainly allowed for three classes of full-
time workers overall, namely, workers with years of service and
seniority; workers with neither years of service nor seniority;
and workers with years of service but no seniority.         This
taxonomy does no violence to the CBA — and it was the union that
urged the taxonomy on Arbitrator Greenbaum in the first place.

                                    -20-
hourly wages" — in a new bottle, and it is equally unpalatable.

See Misco, 484 U.S. at 38.          Put another way, to the extent that

the arbitral award properly can be characterized as embodying a

conclusion that the CBA functioned like a minimum standards

contract, that is a legal conclusion which falls outside the

narrow confines of judicial review.              See id.    Moreover, there is

no sign that Local 42 ever argued this point to the arbitrator,

and it is therefore procedurally defaulted.                     See Dorado Beach

Hotel    Corp.    v.     Union     de    Trabajadores       de        la     Industria

Gastronomica Local 610, 959 F.2d 2, 5-6 (1st Cir. 1992).

           The    related     argument         that     federal       law     requires

employers to negotiate wages with union representatives, see 29

U.S.C. § 159(a), also comes too late in the day.                           The union's

contention before the arbitrator was simply that "the Company is

in   violation    of     Article    13    of     the    collective          bargaining

agreement between the parties."                The statutory argument was,

therefore, waived.

           At any rate, because arbitrators acquire their power

from the parties' agreement to submit to their decisions, they

generally lack the authority, absent a contrary stipulation, to

consider laws external to the CBA.               See Barrentine v. Arkansas-

Best    Freight   Sys.    Inc.,    450    U.S.    728,    744     &   n.23     (1981);

Challenger Caribbean, 903 F.2d at 866.                 That being so, we cannot


                                        -21-
take the arbitrator to task for concentrating on the CBA's

language and not on federal labor law.                See Graphic Arts Int'l

Union Local 97B v. Haddon Craftsmen, Inc., 796 F.2d 692, 697-98

(3d Cir. 1986); cf. Alexander v. Gardner-Denver Co., 415 U.S.

36, 49-50 (1974) (explaining that contractual rights under a CBA

and   statutory   rights    are   "distinctly         separate"   and   may    be

enforced "in their respectively appropriate forums" without

inconsistency).

          The authorities cited by the union do not convince us

otherwise.     In Leed Architectural Products, Inc. v. United

Steelworkers of America, Local 6674, 916 F.2d 63 (2d Cir. 1990),

the   court   affirmed    the   vacatur    of    an    arbitral   award      that

required an employer to pay aggrieved workers the same wage that

it had agreed to pay a new employee.            In that case, however, the

CBA specified a maximum as well as a minimum wage, and the

awarded rate of pay exceeded the cap.            See id. at 64.      Here, the

CBA only sets forth a minimum, and the wage rate paid to the

transferees    (and      sanctioned   by    the        arbitrator)      is    not

inconsistent with it.

          The arbitral decisions cited by Local 42 are beside any

relevant point.       While they suggest that Arbitrator Cooper

interpreted the CBA         differently than other arbitrators in

kindred situations, that suggestion misses the mark.                    Because


                                   -22-
"an    arbitrator's      refusal      to    follow    a    previous   arbitrator's

interpretation of a specific contractual provision does not

expose   an    ensuing       award   to    judicial       tinkering,"     El    Dorado

Technical Servs., Inc. v. Union General de Trabajadores, 961

F.2d 317, 321 (1st Cir. 1992), these citations afford the union

no traction.



                                            D

              Local 42's procedural argument need not detain us.                    It

complains      that,    at    the    arbitration      hearing,     the    arbitrator

denied its representative the opportunity to present evidence.

We    have    perused    the    record       with    care    and   find    that    the

arbitrator merely declined to hear the witness's elucidation of

the contents of certain items of documentary evidence.                           Thus,

the union's claim of error fails.

              Generally speaking, documents are the best evidence of

their contents.         See, e.g., Fed. R. Evid. 1002.                Consequently,

an arbitrator, like a trial judge, usually acts within his

rights in admitting documents into evidence without permitting

external elaboration.           Nothing about this case removes it from

the sweep of this general rule.                   We add only that any error in

this    regard    would      have    been       benign;    the   union    had    ample




                                           -23-
opportunity to explain the significance of the documents in its

post-hearing brief and took full advantage.

IV.    CONCLUSION

            We need go no further.             The arbitral award at issue

here    stemmed      rationally,    if      not      inevitably,            from   the

arbitrator's      construction     of    the    CBA.       It     is    founded     in

reasoning     that    can   be   questioned,         but    not       dismissed     as

chimerical.     It does not depend on invented or imagined facts.

Because this is so, and because the union's claim of procedural

error is jejune, the award must stand.                 When all is said and

done, "courts must confine themselves to determining whether the

arbitrator's      construction     of    the    contract        was    in    any   way

plausible,"    Labor    Relations       Div.,   29   F.3d    at       743,   and   the

decision here passes that undemanding test.



Affirmed.
