Laux v. Mentor Worldwide, LLC

Citation: 295 F. Supp. 3d 1094Docket: Case No. 2:16–cv–01026–ODW(AGR)

Court: District Court, C.D. California; November 7, 2017; Federal District Court

Narrative Opinion Summary

In a lawsuit filed by Anita Laux against Mentor Worldwide, LLC, the court addressed the admissibility of expert testimonies under Federal Rule of Evidence 702 and the Daubert standard. Laux claimed injuries from allegedly defective saline-filled breast implants manufactured by Mentor, asserting manufacturing defects, negligence, and breach of warranty. She presented expert witnesses Dr. Susan Kolb, Dr. Pierre Blais, and Dr. Arthur Brawer to establish a causal connection between her health issues and the implants. The defendant moved to exclude these expert opinions, arguing they were unreliable and the experts were unqualified. The court granted these motions. Dr. Kolb's testimony was excluded due to her lack of qualifications in immunology and mold-related diseases, and her unreliable differential diagnosis. Dr. Blais' testimony was deemed unreliable due to insufficient scientific basis and lack of peer-reviewed support for his theories on implant defects. Dr. Brawer's report failed to meet Rule 26 requirements and lacked scientific evidence for his claim of 'breast implant toxicity.' Consequently, the court excluded all expert opinions, impacting Laux's ability to substantiate her claims of injury from the implants.

Legal Issues Addressed

Compliance with Rule 26 for Expert Reports

Application: Dr. Arthur Brawer's report was excluded for failing to meet the requirements of Rule 26, including a complete statement of opinions and their bases.

Reasoning: The Court agrees with the defendant's assessment, concluding that Dr. Brawer's report does not satisfy the requirements of Rule 26.

Expert Testimony Admissibility under Federal Rule of Evidence 702

Application: The court evaluates the admissibility of expert testimony by ensuring that the testimony is both relevant and reliable, as highlighted by the Daubert standard.

Reasoning: Federal Rule of Evidence 702 establishes a "gatekeeping" role for trial courts to ensure that scientific testimony is relevant and reliable, as reinforced by the Supreme Court in Daubert v. Merrell Dow Pharmaceuticals, Inc.

Methodology and Scientific Basis of Expert Opinions

Application: Dr. Pierre Blais' expert testimony was excluded due to an unreliable methodology and lack of peer-reviewed support for his theories on breast implant defects.

Reasoning: The Court concurs that Dr. Blais lacks the necessary expertise to identify microbiological organisms and that his methodology is unreliable, noting he did not test the implants or establish a scientific basis linking the injuries to Defendant's products.

Qualifications of Expert Witnesses

Application: The court ruled that Dr. Susan Kolb was unqualified to testify on biotoxin disease due to her lack of formal training in relevant scientific fields, thus excluding her testimony.

Reasoning: The Court concurs with Defendant, ruling that Dr. Kolb is unqualified to assert that Plaintiff suffers from biotoxin disease allegedly caused by mold in Mentor Saline Breast Implants.

Reliability of Differential Diagnosis

Application: Dr. Kolb's differential diagnosis was deemed unreliable as it failed to adequately rule out environmental mold exposure as a potential cause of the plaintiff's symptoms.

Reasoning: The Court concludes that Dr. Kolb inadequately accounted for the possible impact of environmental mold on the Plaintiff, rendering her methodology unreliable.
