                           Appeal from the United States District Court
                              for the Eastern District of Louisiana
                                         (93-CV-3860)

                                        December 27, 1995

Before JOLLY, JONES, and STEWART, Circuit Judges.

PER CURIAM:*

        Jose A. Lopez filed this Jones Act suit for damages for personal injuries allegedly sustained
on board the S/S METEOR as a result of an accident on December 17, 1992. The parties stipulated

to Lopez's seaman status and the facts of the accident. The main issue at trial concerned the extent

of Lopez's injuries which could be related to the accident.




    *
      Local Rule 47.5 provides: “The publication of opinions that have no precedential value and
merely decide particular cases on the basis of well-settled principles of law imposes needless expense
on the public and burdens on the legal profession.” Pursuant to that Rule, the Court has determined
that this opinion should not be published.
       The parties presented several expert witnesses who offered conflicting explanations for

Lopez’s back injury. While one witness related Lopez’s symptoms of back pain to the accident,

others attributed them to aging and mild degenerative changes only.

       At the conclusion of the trial, the district court appointed Dr. James C. Butler to provide an

additional medical opinion. Dr. Butler's report stated that "[o]ne cannot determine with any certainty

as to whether these degenerative changes `previously asymptomatic were made symptomatic' by this

accident," but that this was "probably not the case."

       The district court found that "any back problems currently suffered by plaintiff are as a result

of the normal aging process, and cannot be attributed to the negligence of defendant."

                                            DISCUSSION

Standard of causation

       Lopez argues that the district court erred by not applying the proper standard of causation

required by the Jones Act. He argues that using the "featherweight" standard of causation required

would result in a finding that the disabling condition suffered by him was caused by the December 17

accident. He argues that the district court's correspondence to Dr. Butler did not present the doctor

with the proper standard of causation. He contends that the district court's use of the words

"probable cause" in her letter did not properly present the standard of causation, which caused Dr.

Butler to use the incorrect standard.

       Causation questions in admiralty cases are treated as fact questions. Johnson v. Offshore

Exp., Inc., 

, 1352 (5th Cir.), cert. denied, 

(1988). A district court's

findings of fact in an admiralty case may not be set aside unless they are clearly erroneous. Walker

v. Braus, 

, 80 (5th Cir. 1993). A finding of fact is clearly erroneous when, although there

is evidence to support it, the reviewing court, based on all the evidence, is left with the definite and

firm conviction that a mistake has been made. 

erroneous standard of review does not

apply if the district court made t he factual finding under an erroneous view of controlling legal

principles. 

is no evidence in the record to suggest that the district court applied an incorrect legal

standard. The burden of proof on a plaintiff for showing causation in a Jo nes Act case has been

described as "featherweight." 

. This does not mean that the plaintiff wins

if he puts on any evidence of causation. This burden of proof applies in the context of deciding

whether a plaintiff's case should go to the jury when a defendant files a motion for summary

judgment, or a motion for directed verdict at the close of plaintiff's case, or whether a jury verdict

should be upheld when the defendant files a motion for judgment notwithstanding the verdict. See

Springborn v. American Commercial Barge Lines, Inc., 

, 97-100 (5th Cir. 1985). It does

not follow from the featherweight burden "that the plaintiff is entitled to a directed verdict if there

is only slight evidence in his favor." Nor does it follow that "if the defendant wins the verdict, the

plaintiff should be able to overturn it if there is only slight evidence in his favor."

        When the findings of the district court in a bench trial are based on credibility determinations,

this court affords those findings even greater deference. Dardar v. Lafourche Realty Co., Inc., 

, 827 (5th Cir. 1993). The district court's finding that Lopez's back condition was not

related to the accident of December 17 was not clearly erroneous.

        Further, Lopez's suggestion that the district court should have informed Dr. Butler of the

"featherweight" standard of review has no basis in law. As noted above, not only is the standard not

applicable in that context, but any applicable legal standard is for the district court to apply, not the

physician.

Examination of court appointed expert

        Lopez argues that it was reversible error for the district court to accept and consider the

opinion of Dr. But ler without presenting him for examination by the parties prior to rendering

judgment, in violation of Fed. R. Evid. 706. He contends that the district court rendered judgment

while Dr. Butler's opinions remained open, making him unable to obtain Dr. Butler's complete

conclusions through sworn testimony and cross-examination.




                                                    3
        Federal Rule of Evidence 706(a) provides that the district court may appoint an expert

witness, whose "deposition may be taken by any party," and who "may be called to testify by the

court or any party," and who would be "subject to cross-examination by each party, including a party

calling the witness." Rule 706(a) does not explicitly require the district court to "present" the witness

for examination by the parties, as Lopez suggests in his brief without citati on to any authority.

Granted, the application notes to Rule 706(a) state that the "rule has been revised to make definite

the right of any party, including the party calling him, to cross-examine." However, this revision does

not create a right to examine in the first instance absent a request.

        There was a delay of three months from the time Dr. Butler issued his report until the court

rendered judgment. Lopez never asked to depose Dr. Butler and never indicated that he felt that Dr.

Butler's opinion regarding the cause of his back condition was somehow unclear. If Lopez felt that

Dr. Butler's opinion was in some way incomplete, he could have deposed him and/or moved the court

to reopen the evidence for an examination of Dr. Butler.

AFFIRMED.
