EDWARD ROBINSON,

Plaintiff-Appellant,

versus

ENSCO OFFSHORE COMPANY,

Defendant-Appellee.

Appeal from the United States District Court

For the Eastern District of Louisiana

(95-CV-19-C)

May 19, 1997

Before REYNALDO G. GARZA, EMILIO M. GARZA, and DeMOSS, Circuit

Judges.

EMILIO M. GARZA, Circuit Judge: *

Plaintiff Edward Robinson (“Robinson”) appeals the district

court’s dismissal of his action pursuant to Federal Rule of Civil

Procedure 52(c). We affirm.

I

Premiere, Inc., a subcontractor of the Kinlaw Oil Corporation1 Starting fluid dries moisture, thereby assisting in

ignition.

2 At oral argument, counsel for Ensco explained that the

“cage” is four beams that surround the hammer.

3 Section 1333 provides in relevant part:

The district courts shall have original jurisdiction,

exclusive of the courts of the States, of:

(1) Any civil case of admiralty or maritime

jurisdiction, saving to suitors in all cases

all other remedies to which they are otherwise

-2- (“Kinlaw”), employed Robinson as a diesel hammer operator on the

PENROD 90, a drilling vessel owned and operated by Defendant Ensco

Offshore Company (“Ensco”), formerly Penrod Drilling Company

(“Penrod”). On or before September 28, 1992, Penrod had entered

into a Domestic Day Work Drilling Contract-Offshore with Kinlaw.

On May 23, 1993, the Premiere hammer crew and the Penrod

drilling crew were working together to drive conductor pipe. They

had difficulty starting the diesel hammer because it had become

damp, so Robinson attempted to start the hammer by spraying

starting fluid (et her) into it. 1 Robinson was lifted in a “man

rider” by means of an air-hoist approximately forty feet above the

drill f loor to enable him to spray the starting fluid into the

intake port of the hammer. To do so, Robinson had to place his arm

insi de the hammer “cage.” 2 During this spraying process, the

hammer move d or was fired; Robinson sustained severe injuries to

his right arm when it was caught inside the cage and crushed.

Robinson thereafter filed suit against Ensco under the General

Maritime Law, 28 U.S.C. § 1333 3 and 33 U.S.C. § 905(b), 4 seekingentitled. . . .

4 Section 905(b) provides:

In the event of injury to a person covered under this

chapter caused by the negligence of a vessel, then such

person, or anyone otherwise entitled to recover damages

by reason thereof, may bring an action against such

vessel as a third party in accordance with the provisions

of section 933 of this title, and the employer shall not

be liable to the vessel for such damages directly or

indirectly and any agreeme nts or warranties to the

contrary shall be void. If such person was employed by

the vessel to provide stevedoring s e rvices, no such

action shall be permitted if the injury was caused by the

negligence of persons engaged in providing stevedoring

services to the vessel. If such person was employed to

provide shipbuilding, repairing, or breaking services and

such person’s employer was the owner, owner pro hac vice,

agent, operator, or charterer of the vessel, n o such

action shall be permitted, in whole or in part or

directly or indirectly, against the injured person’s

employer (in any capacity, including as the vessel’s

owner, owner pro hac vice, agent, operator, or charterer)

or against the employees of the employer. The liability

of the vessel under this subsection shall no t be based

upon the warranty of seaworthiness or a breach thereof at

t he time the injury occurred. The remedy provided in

this subsection shall be exclusive of all other remedies

against the vessel except remedies available under this

chapter.

-3- damages for the injury to his arm. Under Robinson’s theory of the

case, the accident occurred when the Ensc o driller, Robert Hall,

fired the hammer without warning and wi thout a signal from

Robinson.

D uring the bench trial, Robinson presented the testimony of

several witnesses, including four who had first-hand knowledge of

the accident: himself, Ronnie Thacker, Darrell Broussard, and

Gerald Stelly. Robinson himself was the only witness who was in a

position to see whether he gave a signal to Hal l to fire the5 Specifically, Thacker testified that only after he heard

Robinson shout subsequent to the accident did he walk around the

back of the hammer to look up at Robinson. Broussard testified

that he di d not look at Robinson prior to the accident and would

not have seen a signal if one were given.

6 Though the district court recited Broussard’s testimony

in its factual findings, it explained that Broussard’s testimony

contradicted his deposition testimony to such an extent that the

court did not think Broussard “remembered very much.” Thus, the

court stated that it was “not relying on his testimony either for

or against the plaintiff at this point.”

-4- hammer. Thacker and Broussard both testified that at the time of

the accident, they were not in positions to see a signal if one had

been given. 5 Stelly testified by deposition that he could not

remember whether a signal had been given.

Robinson also testified that the acci dent happened on his

first attempt to start the hammer by spraying starting fluid, and

that he had not previously tried to start the hammer until he went

up with the ether the time the accident occurred. Thacker,

however, testified that he heard Robinson and Broussard attempt to

start the hammer ten times and that he then helped Robinson try to

start it approximately five additional times. Likewise, Broussard

testifi ed that Robinson attempted to start the hammer with

Broussard’s assistance. Thereafter, Broussard took a three to five

hour nap. According to Broussard, when he awoke Robinson was still

attempting to start the hammer and the accident occurred. 6 Stelly

stated that Robinson had sprayed ether ten to fifteen times before

the accident, had used several cans of ether, and that after each

spraying Robinson would either swing away from the cage or stay at-5-

the cage while the driller attempted to fire the hammer.

Charles Boudreaux, Premiere’s district manager at the time of

accident, testified that he went to the hospital a few days after

the accident with Curtis Go nzales, Premiere’s safety director.

Boudreaux stated that Robinson did not know exactly how the

accident occurred, but that Robinson did have “some idea” about how

it happened. Boudreaux testified that Robinson explained to him

that he sprayed the ether in the hammer, swung away from the cage

to hold onto to a beam in the derrick, missed the beam, swung back

into the hammer and was injured. Boudreaux testified that Robinson

never said that the driller fired the hammer when he should not

have done so; in fact, Robinson said nothing about a signal at all.

Robinson, however, denied giving the driller any signal to

move or fire the hammer and denied swinging out to grab the beam or

staying clo se to the cage while the hammer fired. Robinson also

testified that he had no recollection from the moment of the

accident to being in the hospital a few days later. All he

remembered was spraying the ether and feeling the hammer move. He

testified at trial that he had no recollection of speaking to

Boudreaux and Gonzales in the hospital; Robinson had testified in

his deposition, however, that he did remember seeing Boudreaux and

Gonzales in the hospital and that they had as ked him how the

accident had occurred.

After Rob inson presented his case-in-chief, Ensco moved for

involuntary dismissal . The district court took Ensco’s motion7 The court noted that Thacker and Broussard both came on

the scene immediately after the accident and did not know and could

not testify whether there was a signal or where Robinson’s arm was

when the accident occurred. The court also noted that Stelly did

not know whether a signal was given.

-6- under submission and asked Ensco to present its liability witnesses

before the court considered Ensco’s motion. Ensco identified its

liability witnesses as Gonzales, Mike Poche and Daniel Doggett.

Gonzales testified that Robinson told him in the hospital

emergency room that the accident had occurred when Robinson sprayed

the ether, told his assistant Thacker to start the hammer, pushed

off from the ha mmer, missed the beam and swung back into the

hammer. Gonzales testified that Robinson reiterated this account

of the accident when Gonzales visited Robinson again in the

hospital a few days later with Boudreaux. Gonzales testified that

during neither conversation did Robinson say that the driller had

fired the hammer prematurely.

After Gonzales’s testimony, the court took a brief recess and

returned to dismiss Robinson’s action pursuant to Federal Rule of

Civil Procedure 52. The court found that Robinson had not

established by a preponderance of the evidence that Ensco was at

fault in the accident. The court observed that Robinson was the

only witness who testified that the drill er fired the hammer

without warning and without a signal, and concluded that there was

no corr oboration of Robinson’s version of the accident by other

witnesses. 7 The court found Robinson’s recollection of the8 The district court explained that the testimony of all of

the witnesses other than Robinson contradicted Robinson’s testimony

about the circumstances of the accident. Robinson testified that

the accident occurred on his first or second attempt to spray the

ether, and denied both that he had been working on the hammer for

a period of time before the accident and that he had been swinging

out to grab the beam each time while the driller attempted to fire

the hammer. Thacker and Broussard, however, both testified that

Robinson had tried to start the hammer ten to fifteen times before

the accident. Stelly testified that Robinson would spray the ether

and then swing out and grab the beam. Finally, the district court

observed that the account of the accident that Robinson gave to

Gonzales a nd Boudreaux at the hospital, i.e., that the accident

occurred when Robinson sprayed the ether, swung out to catch the

beam, missed the beam, and swung back into the hammer, was

generally consistent with the testimony of the witnesses to the

accident, except for Robinson himself.

-7- accident not sufficiently reliable to sustain his burden of proof. 8

The district court denied Robinson’s subs equent motion for a new

trial. Robinson appeals.

II

A

Robinson’s fir st two arguments attack the trial court’s

findings pursuant to Rule 52: that the findings are inadequate to

give a clear understanding of the process by which the court’s

ultimate conclusions were reached and thus inadequate to permit

appellate review, and that the findings are clearly erroneous. S ee

Curtis v. Commissioner of Internal Revenue , 623 F.2d 1047, 1051

(5th Cir. 1980) ( describing two types of attacks on findings

pursuant to Rule 52). We turn first to Robinson’s contention that

the district court did not provide adequate findings of fact and

conclusions of law as required by Rule 52.-8- 1

Rule 52(c) states that a judgment on partial findings “shall

be supported by findings of fact and conclusions of law as required

by subdivision (a) of [Rule 52].” Rule 52(a) provides that “the

court shall find the facts specially and state separately its

conclusions of law thereon.

. . . It will be sufficient if the

findings of fact and conclusions of law are stated orally and

recorded in open court following the close of the evidence

. . . .”

The purpose of Rule 52(a) is to aid t he appellate court by

affording it a clear understanding of the ground or basis of the

decision of the trial court. S .S. Silberblatt, Inc. v. United

States ex rel. Lambert Corp. , 353 F.2d 545, 549 (5th Cir. 1965).

Failure to meet the technical requirements of Rule 52 does not

warrant reversal or remand as long as the purposes behind the rule

are effectuated. C handler v. City of Dallas

, 958 F.2d 85, 89 (5th

Cir. 1992).

H e nce, Rule 52(a) “exacts neither punctilious detail nor

slavish tracing of the claims issue by issue and witness by

witness.” Schlesinger v. Herzog , 2 F.3d 135, 139 (5th Cir. 1993)

(citations omitted). Rule 52(a) does not require that the trial

court set out findings on all the myriad factual questions that

arise in a case. G olf City, Inc. v. Wilson Sporting Goods Co.

, 555

F.2d 426, 433 (5th Cir. 1977). It simply requires findings that

are explicit and detailed enough to enable us to review them under-9-

the applicable standard. S chlesinger

, 2 F.3d at 139; see also

Lopez v. Current Dir. of Tex. Econ. Dev. Comm’n

, 807 F.2d 430, 434

(5th Cir. 1987) (“The correct application of the clearly erroneous

standard requires that an appellate court be able to discern the

evidentiary basis for a trial court’s factual finding.”).

The district court’s findings of fact and conclusions of law

in this case, made orally as permitted by Rule 52(a), certainly

enable us “to obtain a ‘full understanding of the issues on

appeal.’” C handler

, 958 F.2d at 90 (quoting Texas Extrusion Corp.

v. Palmer, Palmer & Coffee ( In re Texas Extrusion Corp. ), 836 F.2d

217, 221 (5th Cir. 1988)). We are not left “‘[t]o speculate as to

the factual basis for the district court’s conclusion.’” W est Wind

Afr. Line, Ltd. v. Corpus Christi Marine Servs. Co.

, 834 F.2d 1232,

1235 (5th Cir. 1988) (quoting Salinas v. Roadway Express, Inc.

, 735

F.2d 1574, 1578 (5th Cir. 1984)). Rather, the district court made

specific findings supporting its conclusion that Robinson failed to

establish by a preponderance of the evidence that Ensco was at

fault in the accident. In particular, the district court observed

that Robinson was the only witness who testified that the driller

fired the hammer without warning and without a signal. The court

catalogued the testimony of the witnesses to the acciden t and

concluded that no witness c orroborated Robinson’s version of the

accident. The court also provided specific reasons for finding

that Robinson’s recollection of the accident was not sufficiently9 To support his claim that the district court did not

provide adequate findings of fact and conclusions of law, Robinson

presents a list of “factual” questions he claims the district court

failed to answer. The district court’s “failure” to answer

Robinson’s questions, however, does not constitute a violation of

Rule 52. C f. Schlesinger

, 2 F.3d at 139 (“In essence, the

appellants list their own version of the facts and then complain

that the district court violated Rule 52 by ignoring these ‘facts.’

The district court did not ignore facts. It simply found facts

contrary to the appellants’ liking.”).

-10- reliable to sustain his burden of proof. In sum, the district

court’s findings are “sufficiently detailed to give us a clear

understanding of the analytical process by which ultimate findings

were reached and to assure us that the trial court took care in

ascertaining the facts.” Golf City , 555 F.2d at 433. 9

2

Contendin g that he proved Ensco’s fault “based on the

eyewitnesses who were called in [his] case,” Robinson also argues

that the district court erred in finding tha t he had not proved

Ensco’s liability by a p reponderance of the evidence. Robinson

specifically asserts that the eyewitnesses to the accident

demonstrated Ensco’s liability because they testified that Robinson

had not finished spraying the ether when the accident occurred and

that Robinson did not give a signal to the driller to fire or move

the hammer prior to the accident.

We review district co urt judgments on partial findings

pursuant to Rule 52(c) for clear error. S outhern Travel Club, Inc.

v. Carnival Air Lines, Inc. , 986 F.2d 125, 128 (5th Cir. 1993).-11-

See Rule 52(c) advisory committee’s note (judgment on partial

findings, unlike a summary judgment, “is made after the court has

heard all evidence bearin g on the crucial issue of fact, and the

fin ding is reversible only if the appellate court finds it to be

‘clearly erroneous’”).

In other words, we will not set aside the district court’s

finding unless, based upon the entire record, we are “left with the

definite and firm conviction that a mistake has been committed.”

Southern Travel Club

, 986 F.2d at 128 (quoting Anderson v. City of

Bessemer City, 470 U.S. 564, 573, 105 S. Ct. 1504, 1511, 84 L. Ed.

2d 518 (1985)). If the district court’s account of the evidence is

plausible in light of the record, we will not reverse it )) even if

convinced that had we been sitting as trier of fact, we would have

weighed the evidence differently. I d. ; see also Movible Offshore,

Inc. v. M/V Wilken A. Falgout

, 471 F.2 d 268, 271 (5th Cir. 1973)

(“The question is . . . whether the trial court could permissibly

find as it did.”). Where there are two permissible views of the

evidence, the factfinder’s choice betwe en them cannot be clearly

erroneous. Anderson , 470 U.S. at 574, 105 S. Ct. at 1511.

Because this case turned almost exclusively on determinations

regarding the credibili ty of witnesses, Rule 52(a) demands even

greater deference to the trial court’s findings. S chlesinger

, 2

F.3d at 139. Where the court’s finding is based on its decision to

credit the testimony of one witness over that of another, that-12-

finding, if not internally inconsistent, can virtually never be

clea r error. Id. “[O]nly the trial judge can be aware of the

variations in demeanor an d tone of voice that bear so heavily on

the listener’s understanding of and belief in what is said.”

Anderson , 470 U.S. at 575, 105 S. Ct. at 1512.

The district court’s conclusion that no witnesses corroborated

Robinson’s version of the accident, though at odds with Robinson’s

content ion that the eyewitnesses established that no signal was

given, is more than plausible in li ght of the record. Though

Robinson testified that Hall fired the hammer without warning and

without a signal, Thacker and Broussard both came on the scene

after the accident and did not know whether a signal had been given

or where Robinson’s arm was when the accident occurred. Stelly

testified that Robinson had not finished spraying the ether before

the accident occurred, but that he did not know whether a signal

had been given.

Moreover, we find no clear error in the district co urt’s

conclusion th a t Robinson’s testimony lacked credibility. The

testimony of all of the other witnesses contradicted, or at least

did not corroborate, Robinson’s statements about the accident.

Robinson testified that th e accident occurred on his first or

second attempt to spray the ether, and denied both that he had been

working on the hammer for a period of time before the accident and

that he had been swinging out to grab the beam each time while the-13-

driller attempted to fire the hammer. Thacker and Broussard,

however, both testified that Robinson had tried to start the hammer

ten to fifteen times before the accident. Stelly testified that

Robinson would spray the et her and then swing out and grab the

beam. Furthermore, the account of the accident that Robinson gave

to Gonzales and Boudreaux at the hospital, i.e., that the accident

occurred when Robinson sprayed the ether, swung out to catch the

beam, missed the beam, and swung back into the hammer, was

generally consistent with the testimon y of the witnesses to the

accident, except for Robinson himself. The record reveals no clear

error in the district court’s findings and we therefore affirm its

conclusion that Robinson did not establis h Ensco’s fault in the

accident by a preponderance of the evidence.

B

Robinson next contends that the dis trict court erroneously

based its decision on de position testimony that was not entered

into evidence at trial. In its reasons for granting judgment in

favor of Ensco, the district court refers to driller Hall’s

deposition. However, though Hall’s deposition was provided to the

court prior to trial, neither party offered it into evidence.

Robinson’s argument is generally analogous to a claim that the

district court improperly admitted evidence and then relied upon it

in reachin g its decision. In a non-jury case, the admission of

incom petent evidence will not warrant reversal unless all of the

competent evidence is insufficient to support the judgment, or10 See Fed. R. Civ. P. 61 (“No error in either the admission

or the exclusio n of evidence . . . is ground for granting a new

trial

. . . unless refusal to take such action appears to the court

inconsistent with substantial justice. The court at every stage of

the proceeding must disregard any error or defect in the proceeding

which does not affect the substantial rights of the parties.”); 28

U.S.C. § 2111 (“On the hearing of any appeal or writ of certiorari

in any case, the court shall give judgment after an examination of

the record without regard to errors or defects which do not affect

the substantial rights of the parties.”); see also American

Universal Ins. Co. v. Dykhouse , 326 F.2d 694, 697 (8th Cir. 1964)

(finding th a t because substantial evidence existed to support

judgment, trial court’s error in considering depositions which were

filed but not offered as evidence was at most harmless, resulting

in no prejudice to appellant); Oates v . S. J. Groves & Sons Co.

, 248 F.2d 388, 389 (6th Cir. 1957) (per curiam) (finding that where

deposition that was read by district court during recess in trial

but was not formally introduced in evidence dealt with no new fact

not otherwise fully covered by other competent evidence, no

prejudicial error occurred).

-14- unless it affirmatively appea r s that the incompetent evidence

induced the court to make an essential finding wh ich would

otherwise not have been made. Goodman v. Highlands Ins. Co. , 607

F.2d 665, 668 (5th Cir. 1979). 10 As we have concluded above that

the district court did not err in finding, without reference to

Hall’s deposition, that Robinson did not prove his case, we

similarly conclude th at the competent evidence is sufficient to

support the judgment. Thus, we address here only whether Hall’s

deposition testimony induced the district c ourt to make an

essential finding it otherwise would not have.

The district court undoubtedly considered Hall’s deposition in

making its decision. In its reasons for granting judgment in favor

of Ensco, the court stated that “[t]he driller, Mr. Hall, in his-15-

deposition, states that he would not have fired the hammer without

a signal,” and that “Mr. Hall, the driller, also said that the

plaintiff kept spraying the hammer and then he would either swing

away or remain by the cage.” The district court acknowledged,

however, that Hall apparently did not “specifically remember what

happened . . . immediately before the accident.”

Robinson contends that Hall’s deposition induced the court to

find that Robinson signaled prior to the accident. A close reading

of the district court’s findings, however, reveals that it did not

so find. Rather, the court found that Hall did not specifically

remember what had occurred prior to the accident and speculated

that “what may have happened” was that the plaintiff gave a signal

to fire and was injur ed upon missing the beam and swinging back

into the hammer. Though Robinson testified that he did not give

Hall a signal to fire the hammer, no witness with first-hand

knowledge of the accident could corroborate Robinson’s contention.

More over, the district court specifically found that Robinson’s

recollection of the accident was unreliable. Under these

circumstances, any reliance on Hall’s assertion that he “would not

have fired the hammer without a signal” cannot be said to have

induced the court to find that a signal was given when it otherwise

would not have so found. Indeed, the district court made no

finding regarding whether a signal was given; rather, it concluded

that Robinson had not proved that he did not give a signal.

The testimony of other witnesses also corroborat es Hall’s11 One final issue deserves comment. Robinson’s claim that

the district court erron eously relied upon Hall’s deposition

differs from a claim of admission of incompetent evidence in one

respect: opportunity for rebuttal. In a case where the court

admits incompetent evidence , the party opposing its admission

presumably has had an opportunity to rebut that evidence. As he

correctly asserts, Robinson had no opportunity to rebut Hall’s

deposition testimony in this case. Robinson contends that, given

the opportunity, he would have presented the testimony of Daniel

Doggett, a floor hand on the PENROD 90 at the time of the accident,

who gave a statement on the day of the accident that he did not see

a signal prior to the accident.

Under the circumstances of this case, however, we do not think

that Robinson’s lack of opportunit y to rebut Hall’s deposition

requires reversal. The district court heard testimony similar to

D oggett’s proposed testimony from several other witnesses and

Robinson fails to explain how Doggett’s statement differs from that

testimony. C f. Wright v. Southwest Bank

, 554 F.2d 661, 663-64 (5th

Cir. 1977) (finding that dis trict court’s acceptance of, and

reliance on, ex parte evidence was reversible error where opposing

party had no opportunity to test its validity and similar evidence

had not been introd uced, but was harmless error where similar

evidence had been previously introduced into evidence).

-16- statement that Robinson “kept spraying the hammer and then he would

either swing away or remain by the cage.” Stelly testified that

Robinson would spray the ether and then either swing away from the

hammer cage or remain near the cage while the hammer fired.

Similarly, both Boudreaux and Gonzales testified that Robinson told

them that after s praying the ether he swung away from the hammer

cage. Thus, any reliance on Hall’s statement regarding Robinson’s

actions near the hammer before the accident did not induce the

court to make an essential finding it otherwise would not have

made. 11

C

Robinson next argues that the district court erred in granting12 As we have already addressed Robinson’s claim regarding

rebuttal of Hall’s deposition, we devote this discussion o nly to

his claim regarding rebuttal of Gonzales’s testimony.

-17- judgment against him pursuant to Rule 52(c) because Robinson had

not been “fully” heard on the issue of liability because the

district court did not permit Robinson to present rebuttal

testimony. Specifically, Robinson contends that the district court

improperly refused to permit him to rebut Gonzales’s testimony and

Hall’s deposition testimony. 1 2 Whether to allow evidence in

rebuttal is a matter within the trial court’s discretion,

reviewable only for an abuse. Cates v. Sears, Roebuck & Co. , 928

F.2d 679, 685 (5th Cir. 1991).

Rebuttal is a term of art, denoting evidence introduced by a

plaintiff to meet new facts brought out in his opponent’s case in

chief. M organ v. Commercial Union Assurance Cos.

, 606 F.2d 554,

555 (5th Cir. 1979); see also Rodrig uez v. Olin Corp. , 780 F.2d

491, 496 (5th Cir. 1986) (“[E]vidence is new if, un der all the

facts and circumstances, the court concludes that the evidence was

not fairly and adequately presented to the trier of fact before the

defendant’s case in chief.”). Gonzales’s testimony, however, did

not present new facts. Rather, Gonzales simply reiterated facts

that had been elicited from Boudreaux by Ensc o during crossexamination.

Nor did the district court abuse its discretion in refusing to

permit Robinson to present rebuttal testimony from family members-18-

to establish that Robinson was “incoherent” while in the hospital,

and therefore “incoherent” during the con versation with Gonzales

and Boudreaux. Both Boudreaux and Gonzales testified that they did

not remember any family membe rs being present during their

conversation with Robinson in the hospital. Moreover, Robinson’s

wife testified that Robinson “didn’t say too much in the hospital.

He just was in a lot of pain,” and that Robinson “wasn’t responding

to anyone” while in the hospital. Even Boudreaux testified that

Robinson “was a little disoriented, because of pain pills. I guess

he was on pain pills.” In light of this testimony, the district

court did not abuse its discretion in refusing to take additional

testimony regarding Robinson’s alleged “incoherence” while in the

hospital. S ee Tramonte v. Fibreboard Corp.

, 947 F.2d 762, 766 (5th

Cir. 1991) (“A trial court does not abuse its discretion in

excluding rebuttal evidence when the offering part y already has

pre sented evidence on the same issue as a part of its case.”);

Orduna S. A. v. Zen-Noh Grain Corp.

, 913 F.2d 1149, 1154 (5th Cir.

1990) (same).

D

Robinson also a rgues that the district court erred in

excluding the expert testimony of Robinson’ s witness Edward B.

Robert, Jr. on the issue of safety standards in the industry. The

admission or exclusion of expert testimony is a matter left to the

discretion of the trial judge, and his or her decision will not be-19-

disturbed on appeal unless it is manifestly erroneous. Smogor v.

Enke

, 874 F.2d 295, 297 (5th Cir. 1989) (quoting Perkins v.

Volkswagen of Am., Inc.

, 596 F.2d 681, 682 (5th Cir. 1979)); s ee

also Phillips Oil Co. v. OKC Corp. , 812 F.2d 265, 280 & n.32 (5th

Cir.) (quoting and relying on Perkins

, and explaining that the

“manifest error” standard is harmonious with the “abuse of

discretion” standard as applied to this issue in other Fifth

Circuit cases), cert. denied , 484 U.S. 851, 108 S. Ct. 152, 98 L.

Ed. 2d 107 (1987).

Ensco moved in limine to exclude Robert’s testimony regarding

the functioning of a diesel hammer. Robinson opposed the motion,

arguing that Robert should be permitted to testify regarding “the

functioning and safe operation of the hammer under the existing

circumstances.” In his opposition to the motion i n limine

,

Robinson also included a list of propositions to which he asked

Ensco to stipulate in exchange for Robinson’s agreement not to

present Robert’s testimony. Included in this list is the statement

that “[t]he driller should not fire or move the hammer at any time

when the hammer operator is not in a position of safety away from

the hammer.”

On the morning of trial, the district court ruled on Ensco’s

motion in limine as follows:

The second motion was to exclude the plaintiffs [sic]

safety expert. The plaintiffs [sic] can use any witness

with knowledge that he wishes including the safety expert-20-

t o explain the use of the equipment that was in volved

with this injury. I do not need the expert’s opinion on

the cause of the accident however.

Vol. 4, 4:15-20. Then, prior to Robert’s testimony, the court

instructed him that he could testify about

[h]ow the piece of equipment works. How this goes this

way, that goes t hat way. . . . I’m not taking any

opinions as to whether it was operated safely that day or

anything along those lines.

Vol. 4, 55:7-10 (emphasis added).

In other words, thoug h Robinson maintains that the district

court prevented him from presenting expert testimony re garding

safety procedures in the indu stry, the plain language of the

district court’s ruling and subsequent clarification reveal that it

did not prohibit Robert from explaining industry safety procedures.

To the contrary, the court only excluded Robert’s testimony insofar

as it bore on the ultimate question of the cause of the accident.

Our review of the record reveals no occasion on which Robinson

either attempted to clarify the court’s ruling regarding Robert’s

testimony or was prohib ited by the court from questioning Robert

regarding safety procedures in the industry. Under these

circumstances, the district court’s decisio n to exclude Robert’s

expert testimony on the ultimate issue of the cause of the accident

was not manifestly erroneous.

Robinson last argues that the district court erred in refusing

to permit him to introduce evidence that Premiere was adverse to13 The Master Service Contract between Premiere and Kinlaw

provides:

5.1 CONTRACTOR [PREMIERE, INC.] shall defend, indemnify

and hold KINLAW and its parent or affiliated companies

harmless from and against every

. . . demand, claim,

cause of action, loss, liability, or expense (including

legal fees) arising in favor of CONTRACTOR, CONTRACTOR’S

employees or agents, or CONTRACTOR’S subcontractors or

their em ployees on account of personal injury . . .

or in part, by the sole or concurrent negligence

preexisting condition.

-21- him. Apparently Robinson refers to the district court’s refusal to

permit him to cross-examine Gonzales regarding an alleged indemnity

agreement between Premiere and Kinlaw. 13 We review a district

court’s evidentiary rulings for an abuse of discretion. L eBoeuf v.

K-Mart Corp. , 888 F.2d 330, 333 (5th Cir. 1989).

Robinson argues that the indemnity agreement would have shown

Gonzales’s bias and his reason for testifying in a manner adverse

to Robinson. Robinson also claims that he would have used the

agreement to impeach Boudre aux and Broussard, his own witnesses.

A plain reading of the contract, however, reveals only that

Premiere owed defense and indemnity to Kinlaw, not to Kinlaw’s

subcontractor Ensco. Robinson does not argue, and indeed the

contract does not provide, that Premiere owed Kinlaw indemnity for

its defense and indemnity of Ensco. Robinson does not explain how

under these circumstances the Premiere witnesses, including those

called by Robinson himself, would have had a bias. Kinlaw did not-22-

tender the defense and indemnity of Ensco to Premiere, and the

terms of the contract do not indicate that it could. As a result,

we find no abuse of discretion in the district court’s refusal to

permit Robinson to cross-examine Gonzales about the indemnity

agreement between Kinlaw and Premiere.

For the foregoing reasons, we AFFIRM the ju dgment of the

district court in all respects.
