Louisiana Court Limits Use of Biomechanical Expert Testimony

Published on: June 7, 2022

The use of biomechanical expert testimony in Louisiana courts has evolved over the last few years. A recent decision from the Louisiana Fifth Circuit Court of Appeal provides an example of the changing standards for the admissibility of biomechanical expert testimony and its relation to medical causation.

In Pollard v. 21st Century Centennial Ins. Co., 21-65 (La. App. 5 Cir. 12/23/21), 334 So. 3d 1013, writ denied, 2022-00163 (La. 4/20/22), the defendants argued that the underlying accident involved a minor rear-end impact not likely to cause injury. The defendants hired a biomechanical expert who was also a medical doctor. The expert performed an “impact severity analysis” to determine the force of impact in the collision.

The expert concluded that the accident involved a minimum damage collision; he relied upon the “force reflection method” and test data at his crash test facility to determine how fast the rear-ending vehicle would have traveled to cause the damage present on the plaintiff’s vehicle. Based upon his findings, the expert opined that the plaintiff was not seriously injured in the collision. He went further to testify that specific injuries could not have been caused by the forces involved.

The Fifth Circuit noted the same expert was previously excluded in a case that went to the Louisiana Supreme Court in Blair v. Coney, 2019-00795 (La. 4/3/20), reh'g denied, 2019-00795 (La. 7/9/20), 298 So. 3d 168, where the Court found the expert’s testimony to be based upon insufficient facts or data. In Blair, the Supreme Court found the expert’s testimony should be excluded because he did not (1) inspect either vehicle involved in the collision; (2) speak with the damage appraisers; (3) know the plaintiff’s body position at the time of the accident; (4) inspect plaintiff’s vehicle for variance from the test-vehicle or (5) interview the plaintiff. Thus, his testimony failed to meet the requirements of C.E. art. 702(A)(2).

Citing the Blair decision, the Louisiana Fifth Circuit in Pollard concluded that the expert “relied on the same [improper] methodology in reaching his conclusions.” Therefore, the appellate court found the trial court erred in denying a motion in limine to exclude the expert’s testimony. Although the expert cited to peer-reviewed literature to support his conclusions, the evidence revealed that “most of the research and articles” he cited were either written by him or one of his employees.

Effective January 1, 2021, Louisiana amended La. R.S. 32.295.1, which now allows the admission of a plaintiff’s failure to wear a seat belt as a factor to be considered in comparative fault. Defendants will seek to use biomechanical experts to prove that the failure to use a seatbelt substantially caused or contributed to the damages.

Biomechanical testimony may be allowed. However, as shown in Pollard, biomechanical opinions which lack sufficient inquiry to match the analysis to the real-world impact will be treated with skepticism. Taking Blair and Pollard together, the courts appear to resist expert biomechanical opinions which seek to definitively resolve medical causation which often involves subjective elements and credibility determinations reserved for the trier of fact.

It is certain that defendants will continue to advance the “low impact” argument because force-of-impact testimony is a relevant factor in determining causation or extent of injuries. See, e.g., Merrells v. State Farm Mutual Auto, Ins. Co., 33-404 (La. App. 2 Cir. 6/21/00), 764 So. 2d 1182. What is less than certain is the role of the biomechanical expert. Following the Fifth Circuit’s decision in Pollard, the Louisiana Supreme court denied the defendant’s writ application 4 to 3, with all three dissenters advising they would have granted the writ. Issues surrounding the use and scope of testimony from biomechanical experts appear far from settled.

Federal Jury Finds For Employer in ADA Case

In a case handled by our firm, a Lafayette-based global catering and life support client was sued by an employee based in Dubai for alleged violations of the Americans with Disabilities Act. The jury unanimously found that the employer (1) did not discriminate against the plaintiff because of a disability or (2) retaliate against him because he raised a complaint regarding the alleged discrimination.

The plaintiff had a written contract of employment with a one-year term that automatically renewed if he was not terminated. Upon the contract expiration date, the employer advised plaintiff that the contract would not be renewed for a successive term.

Plaintiff, an Army veteran, suffered from PTSD following his military service and deployment in Iraq. He claimed defendant discriminated against him on the basis of his PTSD, which he claimed as a mental health disability. Plaintiff further claimed that defendant retaliated against him after he complained to his direct supervisor and the head of human resources about the alleged discrimination. To support his case, plaintiff claimed he was not disciplined before his termination and did not receive negative performance reviews during employment. Significant pre-trial motion practice occurred and framed the issues for trial in two ways.

First, the defense learned of actions taken by plaintiff following the termination of his employment that would have provided a legitimate basis for termination had the actions been discovered before he was terminated. The defense argued that evidence of such “after-acquired” misconduct was relevant to credibility and independently relevant to calculate backpay that plaintiff sought, citing McKennon v. Nashville Banner Pub. Co. and McClung v. Hajek. Over defendant’s objection, the Trial Court excluded the evidence as highly prejudicial, instead finding that back pay was an equitable remedy to be decided by the Court in a subsequent evidentiary hearing related to the issue of back pay.

Second, the defense argued that non-certified medical record evidence submitted by plaintiff was hearsay and thus inadmissible to prove a disability. The Court agreed with the defendant and issued a limiting instruction that the jury was not to consider uncertified medical records for the truth of the matter asserted.

At trial, our client presented ample evidence of plaintiff’s performance deficiencies with respect to the vetting of vendors, which jeopardized the employer’s government contracts and the jobs of other employees. The majority of plaintiff’s performance issues arose in Dubai, plaintiff’s key area of oversight. Therefore, it was unbelievable that he would not know of, or take responsibility for, those performance deficiencies. In addition, the language of the written employment contract allowed for non-renewal of the contract. In a unanimous verdict as required by Fed. R. Civ. P. 48, the jury ultimately found that although the plaintiff proved he suffered a disability, he failed to prove discrimination or retaliation under the Act.

Is Your Neighbor a Nuisance?

The poet Robert Frost famously wrote that: “Good fences make good neighbors.” But what if there is a problem even fences won’t solve? Louisiana law offers some answers.

Under Louisiana law, a landowner cannot use their property in a manner that interferes with their neighbor’s enjoyable use. While a neighbor may have to put up with some inconveniences, excessive inconveniences that cause damage may be actionable. If a landowner’s activity is considered a nuisance, he may be liable for damages, and the court may require the landowner to stop the activity.

To determine whether a particular activity is considered a nuisance, courts look to the following factors: (1) the character of the neighborhood; (2) the degree of the intrusion; and, (3) its effect on the use and enjoyment of neighboring properties. For example, a person living in a heavy industrial area may have to put up with more noise than someone living in the suburbs. Whether activity is considered a nuisance is determined on a case-by-case basis.

Further, the nature of the noise and its persistence and duration can be a factor in determining whether the activity is a nuisance. For example, in Parish of E. Feliciana ex rel. E. Feliciana Parish Police Jury v. Guidry 2004-1197 (La. App. 1 Cir. 8/10/05), 923 So. 2d 45, writ denied, 05-2288 (La. 3/10/06), 925 So. 2d 515, the court looked not only at the level of the noise, but also at the “nature” of the noise. The court held that noise from a motor cross track was a nuisance, likening the noise to a chainsaw, a buzzing bee, or a dentist drill.

Even when a landowner has a right to conduct a business on his property, he cannot create a nuisance in running the business. Louisiana courts have held that noxious smells, dust, debris, rats, flies, and noise may all constitute a nuisance, even if the business was otherwise lawful.

The duty owed to neighbors applies not only to the landowner, but may also apply to tenants or contractors performing “work” on the property. To prove a nuisance, the offended neighbor must show that the landowner/tenant/contractor either “knew or should have known” that the activity was a nuisance.

When mending fences is not possible, you may have other options.
