   WISDOM, Circuit Judge:

This appeal involves a medical malpractice action brought under Mississippi law. Because we find that the district court erroneously instructed the jury regarding the standard of care applicable to the defendant physician’s conduct, we reverse and remand.

BACKGROUND

On November 7, 1989, the plaintiffs, John M. Goldman, Jr., a minor, by and through his mother and next friend, Deborah Goldman, Deborah Goldman individually, and John M. Goldman, Sr., filed this medical malpractice action against Julius Bosco, M.D., George Henneberger, M.D., the Women’s Clinic, Inc., and the Singing River Hospital and its Board of Trustees. Jurisdiction was based on diversity of citizenship. The plaintiffs allege that the defendants were negligent during Deborah Goldman’s delivery of John Goldman Jr. on November 4, 1975, causing irreversible brain damage to the newborn child. The district court dismissed the claims against the Singing River Hospital and its Board of Trustees. The case proceeded to trial, and the jury returned a verdict for the remaining defendants, finding specifically that neither Bosco, Henneberger, nor the Women’s Clinic was negligent in the care of Deborah Goldman or John Goldman, Jr.

The plaintiffs moved for a new trial, arguing that the district court erroneously instructed the jury regarding the applicable standard of care, asserting that the district court abused its discretion in making certain evidentiary rulings, and urging the court for a new trial because of an improper comment by defense counsel. The district court denied the motion. The plaintiffs filed a timely notice of appeal.

DISCUSSION

The most significant issue in this appeal is whether, under Mississippi law, a national standard of care or local standard of care should be applied to the defendant physicians’ 1975 conduct. Initially, the district court, ruling on a motion in limine, determined that a national standard of care applied. Later, the district court reconsidered the issue and decided to apply the local standard of care.

Because we sit in diversity, we must apply Mississippi law. Generally, we review the district court’s ruling on a motion for new trial for an abuse of discretion, but asserted legal errors are reviewed de novo

At trial, the district court instructed the jury to apply a local standard of care to the defendant physicians’ conduct:

In this case, when determining whether the plaintiffs have demonstrated by a preponderance of the evidence that [the defendants] were negligent ... you must determine whether the degree of care and skill exercised by [the defendants] fell below the level of care and skill which would have been exercised by a minimally competent, reasonably prudent obstetrician under the same or similar circumstances practicing in the Pascagoula, Mississippi, medical community in 1975.

The plaintiff argues that the district court erred as a matter of law because under Mississippi law a national standard of care should have been applied to the defendant physicians’ conduct. In 1985, in Hall v. Hilbun the Mississippi Supreme Court abandoned the local standard of care and adopted a resource-based national standard of care, which is as follows:

[T]he physician’s non-delegable duty of care is this: given the circumstances of each patient, each physician has a duty to use his or her knowledge and therewith treat through maximum reasonable medical recovery, each patient, with such reasonable diligence, skill, competence, and prudence as are practiced by minimally competent physicians in the same specialty or general field of practice throughout the Untied States, who have available to them the same general facilities, services, equipment, and options.

The Hall decision adopted both a new standard of care for physicians and a new evidentiary rule regarding who may qualify as an expert witness. Hall makes clear that a medical expert may be qualified without knowledge of the particular community, as long as the expert is familiar with the facilities, resources, services and options available.

The court then addressed whether its decision would apply retroactively. The court recognized the general rule that “judicial decisions ordinarily apply retroactively”, and noted that other states had abolished locality rule by simply adopting the national standard of care and applying it retroactively “in a normal fashion without fanfare”. The Hall court, however, carefully considered the retroactivity issue.

The retroactivity question with regard to the evidentiary rule — who may qualify as an expert witness — is easy____ [The evi-dentiary rule] should be applied in the trial of this case on remand[,] ... in any case in which an appeal is pending[,] ... [and] to all cases tried after this date.
The retroactivity vel non of the rule regarding the physician’s duty of care is arguably more difficult. Injustice would necessarily attend our passing judgment on the conduct of a citizen by reference to substantive rules substantially different from those in effect and relied upon by the citizen at the time of his conduct. We recognize that “the confidence of people in their ability to predict the legal consequences of their actions is vitally necessary to facilitate the planning of primary activity”.
These fundamental premises have more validity in contracts, property or other business or economic contexts than in tort cases. Still if it could be demonstrated that at the time Dr. Hilbun prescribed post-operative care for Mrs. Hall he acted in reliance upon the validity of standards substantially more favorable to him than those we state today, that would weigh heavily in support of non-retroactivity. We do not perceive this to be the ease.
What we say today with regard to the standard of care amounts to little more than the law catching up with the way physicians have practiced their profession for years. Moreover today’s decision was “clearly foreshadowed” by the dictum in Dazet v. Bass, and by King v. Murphy. We today do little more than fulfill the prophecy of Dazet and smooth some of King’s rough edges. Seen in this context, retroactivity works no unfairness.

Thus, the 1985 Hall decision retroactively applied the resourced-based national standard of care to 1978 conduct. The Hall court found that Dazet v. Bass, a 1971 decision, “clearly foreshadowed” the eventual adoption of the national standard of care, thus mitigating any unfairness to the defendant physicians.

In Dazet the plaintiff attacked the locality rule.

Plaintiff contends with a great deal of force that the so-called “locality rule” is no longer valid for the reason that physicians now attend the same colleges, receive the same post graduate courses in their specialties, and go to the same seminars; that the standards of care for a specialist should be and are the same throughout the country, and that geographical conditions or circumstances are no longer valid as controlling the standards of a specialist’s care or competence.

Although the court rejected the plaintiff’s argument on procedural grounds, the court noted that the point had “considerable force”.

In another 1985 case, Reikes v. Martin, the Mississippi Supreme Court applied Hall. In Reikes, the court found numerous errors occurred during trial and remanded the case. The court instructed:

[I]n view of our recent decision in Hall v. Hilbun, we hold that [the expert’s] testimony cannot be excluded simply because he was not familiar with the practice of medicine in the locality of Hattiesburg. Upon retrial, as to this aspect of his competency as an expert witness, the circuit judge will be governed by the criteria we set forth in Hall v. Hilbun.

Reikes is significant here. The conduct at issue in Reikes occurred in 1975. The majority opinion clearly requires that the trial court apply the evidentiary rule propounded in Hall. The majority does not expressly state that the national standard of care applies retroactively to the same conduct, but the evidentiary rule and the standard of care seem inextricable. According to the majority, the trial court could not require that the expert witness be “familiar with the practice of medicine in the locality of Hattiesburg”. If the expert is not familiar with the locality, then he could testify only as to the resource-based national standard.

This line of precedent supports the plaintiffs contention that the resource-based national standard adopted in Hall should have been applied to the defendant physicians’ 1975 conduct. The district court, in reversing its decision to apply the national standard, relied on Presley v. Mississippi State Highway Comm’n. This reliance is misplaced.

In Presley, the Mississippi Supreme Court found portions of the Mississippi Sovereign Immunity Act, Miss.Code Ann. § 11-46-1 et seq, unconstitutional and considered whether to strip the state of immunity retroactively. The court observed that “[t]o hold now that no immunity has existed since 1984 poses fiscally disastrous consequences to our state and its political subdivisions”, and that “our decision today has not been ‘clearly foreshadowed’ ”. The court also addressed the special nature of the retroactivity issue presented in Presley.

[W]e do not here deal with tortfeasors in the ordinary sense. That is, we do not deal with human beings guilty of careless or intentional wrong. There is no immunity accorded the active wrongdoer by the [Mississippi Sovereign Immunity Act]. What we treat here is the question whether the taxpayers stand exposed to liability for such wrongs.

As the Presley court pointed out, the ret-roactivity issue presented in that case differs greatly from the retroactivity issue presented here. The instant case deals with the actions of “tortfeasors in the ordinary sense” not actions that could affect the state treasury.

The district court bolstered its decision to apply the local standard of care by relying on certain language in the Hall decision. The Hall court stated that “if it could be demonstrated that at the time Dr. Hilbun prescribed post-operative care for Mrs. Hall he acted in reliance upon the validity of standards substantially more favorable to him than those we state today, that would weigh heavily in support of non-retroactivity”. The district court then determined that the defendant physicians in this case relied on local standards “substantially more favorable” to them than the resource-based national standard. The problem with the district court’s approach is that the Hall court itself broadly rejected the possibility that the defendant physician in that case had justifiably relied on a more favorable distinct “local” standard of care; “[w]hat we say today with regard to the standard of care amounts to little more than the law catching up with the way physicians have practiced their profession for years”. As pointed out by the court in Hall, the historical justification for such “local” standards was seriously questioned by the court as early as 1971 in Dazet.

The Hall court carefully considered the retroactivity issue in the context of medical malpractice and decided that applying the resource-based national standard of care to the defendant physician’s 1978 conduct was merely a recognition “of the way physicians have practiced their profession for years”. There is no indication in the Hall decision, or any subsequent case, that the Mississippi Supreme Court would hesitate to apply Hall to conduct occurring just three years earlier. In fact, in Reikes the court did just that. In the light of all of the above, the district court should have followed Hall and instructed the jury as to the resource-based national standard of care.

We have considered the other issues raised by the plaintiff and find them without merit.

Accordingly, we REVERSE the district court’s ruling denying plaintiffs motion for new trial and REMAND this ease for a new trial consistent with this opinion.

In Chevron, the Court held that, as a threshold matter, "the decision to be applied nonretroac-tively must establish a new principle of law ... by deciding an issue of first impression whose resolution was not clearly foreshadowed".
