Lita St. John filed a medical malpractice suit against Dr. Linda Peterson, claiming negligence in the repair of a vesicovaginal fistula following a hysterectomy performed by Dr. Peterson in May 2006. After a jury verdict favored Dr. Peterson, St. John appealed, arguing that the trial court improperly excluded evidence of Dr. Peterson's prior failures in repairing similar fistulas. St. John experienced uncontrollable urination shortly after the hysterectomy and was diagnosed with a vesicovaginal fistula. Dr. Peterson made four attempts to repair the fistula using various techniques, all of which failed, while another physician eventually succeeded using traditional methods.

St. John, along with three other women who also claimed injuries from Dr. Peterson's hysterectomies, alleged negligence and deviation from the standard of care. The trial court severed the cases to avoid undue prejudice. Before the trials, Dr. Peterson successfully moved to exclude evidence of prior lawsuits against her. Despite a three-day trial in November 2009 resulting in a hung jury, the court reaffirmed the exclusion of prior claims in a subsequent trial scheduled for August 2010, prohibiting St. John from introducing any evidence regarding Dr. Peterson's treatment of other patients with vesicovaginal fistulas. The Supreme Court reversed the trial court’s decision and remanded the case for further proceedings.

At the pretrial hearing, St. John sought to ask Dr. Peterson about past issues with a specific medical procedure, but the trial court denied this question, reasoning that prior problems did not necessarily indicate a fault in the current case. St. John contended that this ruling improperly expanded the scope of Dr. Peterson’s motion in limine. During the trial, St. John presented expert testimony from Dr. Arnold Wharton, who reviewed the medical records of St. John and three co-plaintiffs, all of whom developed fistulas under Dr. Peterson’s care within 18 months. Dr. Wharton asserted that the failed attempts to repair these fistulas indicated Dr. Peterson's incompetence in performing the procedure. 

In the subsequent trial, which took place in August 2010, the jury ruled in favor of Dr. Peterson. St. John appealed, claiming the trial court abused its discretion by excluding evidence of Dr. Peterson's experience with similar procedures. The standard of review for evidentiary rulings presumes correctness unless a clear abuse of discretion is shown. The trial court had previously granted a motion to sever the cases, citing the differences in medical diagnoses among the plaintiffs and the potential prejudice to Dr. Peterson if the cases were tried together. The court maintained that while some relevance existed regarding other procedures, this did not outweigh the potential prejudice of introducing evidence from unrelated cases. Thus, the court concluded that the inquiry into other patients' experiences was not sufficiently relevant to the issue of malpractice concerning St. John.

The court allows for the potential introduction of impeachment evidence, contingent upon prior approval. However, it finds insufficient relevance concerning other patients involved in lawsuits to justify the potential prejudice from admitting such evidence. A written order from the trial court specifies that if St. John intends to present evidence related to other claims against Dr. Peterson, this must be discussed in advance with the court. 

For evidence to be admitted, it must first be deemed relevant according to SDCL 19-12-1 (Rule 401), which defines relevant evidence as that which affects the probability of a consequential fact's existence. The standard for relevance is lenient, allowing evidence that could alter the probabilities, though it may still be excluded for other reasons. The trial court did not clearly determine the relevance of St. John's evidence, only indicating a lack of sufficient relevance to outweigh prejudice. 

Determining relevance is a prerequisite to evaluating admissibility under SDCL 19-12-2 (Rule 402), which states that all relevant evidence is admissible unless excluded by statute. St. John's appeal focuses on Rule 403, which permits exclusion if the probative value is substantially outweighed by the risk of unfair prejudice. Unfair prejudice arises when evidence influences the jury in an illegitimate manner. Once evidence is found relevant, the presumption favors its admission, and the burden lies with the party opposing the evidence to demonstrate that the prejudicial concerns significantly outweigh its probative value.

Dr. Peterson bore the burden of proof at the trial court level, while on appeal, St. John must show that the trial court abused its discretion regarding evidentiary rulings. The trial court ruled that the relevance of certain evidence was insufficient to outweigh its potential prejudicial impact, but misapplied the relevant legal standard by failing to perform the necessary balancing test under Rule 403. This omission raises concerns about whether the court's decision was justified, as an abuse of discretion can manifest as an error of law or as a judgment exercised for unjustified reasons. The appellate court noted that the exclusion of the evidence likely affected the jury's verdict, indicating a prejudicial error. Ultimately, the appellate court determined that the trial court made a fundamental error in judgment, reversing the decision and remanding the case for further proceedings. Justices KONENKAMP, ZINTER, SEVERSON, and Retired Justice MEIERHENRY concurred, while Justice WILBUR did not participate in the case.
