McCreless v. GLOBAL UPHOLSTERY CO., INC.McCreless v. GLOBAL UPHOLSTERY CO., INC.
MEMORANDUM OPINION
The court has for consideration the motion of defendants, Global Upholstery Co., Inc. (“Global”) and Ram Machines (1990) Ltd. (“Ram”) (together, “defendants”), to exclude the report and testimony of Raymond Thompson, Ph.D., P.E. (“Thompson”), who is the expert witness proffered by plaintiff, Joan McCreless (“McCreless”), in the above-entitled products-liability case. Also before the court is the motion of defendants for summary judgment. Defendants contend that Thompson’s opinion testimony does not qualify as the relevant scientific knowledge required by Federal Rule of Evidence 702, and because it must be excluded, McCreless cannot proceed. The question is whether there is a sound scientific basis for Thompson’s conclusion that there is a causal connection between an allegedly defective chair and the injury sustained by McCreless when she used the chair.
This court respects Thompson’s credentials. He is entirely qualified to speak on the subject at hand up to a point, but not on the ultimate question of liability, as he purports to do in his report. In discharging the difficult obligation pointedly laid upon this court by the Eleventh Circuit in
McClain v. Metabolife Intern., Inc.,
Facts
The basic facts of this case are simple, straightforward, and undisputed. On September 19, 2003, while at work as a property clerk for the Birmingham Police Department, McCreless attempted to sit in a one-year-old chair that was manufactured by Global and that contained components manufactured by Ram. McCreless had sat in the chair without incident numerous times during the previous year, but on this particular occasion the chair seat rapidly dropped and tilted forward. This action caused her to be thrown from the chair, whereupon she sustained painful back injuries when her body twisted and the chair rolled backward behind her. Since her fall McCreless has undergone four operations on her back, including a spinal fusion. Inspection of the chair after the accident revealed that some of the chair’s components were unserviceable or broken. In Thompson’s expert report, he says that the pneumatic piston used to raise and lower the seat was not working properly, and that a bracket attaching the pneumatic piston to the seat was fractured. The report contains no finding as to the age of the fracture, or when the pneumatic piston first malfunctioned, or the degree of wear and tear on the chair. There is no evidence to suggest that a Global chair like this model has ever before malfunctioned in a way to cause personal injury.
McCreless filed her complaint on September 19, 2005, asserting claims against Global under theories of negligent and wanton conduct, failure to warn, breach of contract, breach of warranty, and the Alabama Extended Manufacturer’s Liability Doctrine (“AEMLD”). She amended her complaint to add Ram and Leggett & Platt Canada Corporation, d/b/a Northfield Metal Products (“Northfield”), as defendants, but the action as to Northfield was dismissed upon plaintiffs motion, leaving as the only defendants the two who now move for summary judgment.
Defendants’ Daubert Motion
I. Legal Standard
Defendants contend that Thompson’s testimony must be excluded because it would not assist the trier of fact and because Thompson failed to base his conclusions on the proper scientific methods required by Federal Rule of Evidence 702.
1
As the proponent of this testimony, McCreless bears the burden of establishing its admissibility.
United States v. Williams,
Rule 702 is designed to ensure both that expert evidence has an adequate factual basis and that it meets a minimum standard of reliability. In
Daubert v. Merrell Dow Pharmaceuticals, Inc.,
In order to satisfy its
Daubert
obligation, enforced and reinforced on this court by the Eleventh Circuit in
McClain,
this court must “engage in a rigorous inquiry to determine whether: (1) the expert is qualified to testify competently regarding the matters he intends to address; (2) the methodology by which the expert reaches his conclusion is sufficiently reliable as determined by the sort of inquiry mandated by Daubert; and (3) the testimony assists the trier of fact, through the application of scientific, technical, or specialized expertise, to understand the evidence or to determine a fact in issue.”
Rink v. Cheminova, Inc.,
To evaluate the reliability of Thompson’s proffered testimony, the methods, procedures, and reasoning he used in reaching his ultimate opinions must be evaluated. As the Supreme Court held in
Kumho Tire Co., Ltd. v. Carmichael,
the trial court must ensure that “an expert, whether basing testimony upon professional studies or personal experience, employs in the courtroom the same level of intellectual rigor that characterizes the practice of an expert in the relevant field.”
In
Daubert,
the Supreme Court pointed to several non-exclusive factors to guide the trial court’s reliability analysis, including: (1) whether the expert’s theory has
Reliability alone is not enough. In order for expert evidence to be admissible, it must also be relevant. Under the
Dau-bert
regime, the trial court must determine that the proffered testimony is sufficiently related to the issues in the particular case so that it will assist rather than confuse the trier of fact in resolving the dispute, in this case, the ultimate questions leading to liability under plaintiffs theories.

II. Daubert Analysis
To briefly review, evidence is admissible under Rule 702 if it (1) is offered by a qualified expert; (2) is the product of reliable scientific methods; and (3) is relevant and of assistance to the trier of fact. This court’s Daubert analysis begins with a clarification of what is not at issue in this case. First, Thompson is unquestionably qualified and competent to testify about matters related to the science, engineering, and testing of solid materials. This was also true of the two highly credentialed witnesses this court erroneously allowed to testify in McClain. Thompson’s professional record provides ample basis for finding that he is an expert in the broad subject of materials failure analysis. Therefore, this court easily finds that the first part of the three-part test is satisfied. Thompson is not, however, a mechanical engineer or an expert in force dynamics, and his opinions on matters related to these fields do not pass the scrutiny required by Daubert Thompson’s testimony regarding causation and alternative designs also satisfies the third part of the test. His testimony in this regard is undoubtedly relevant, because it would be of assistance to the jury and is, in fact, indispensable to a jury verdict in favor of McCreless. It passes the third part of the Daubert test. However, after an analysis of the methods and procedures Thompson employed to reach his conclusions, the court finds that they are not, as a whole, sufficiently reliable to pass muster under Daubert. Because Thompson reached his causation and alternative-design conclusions via inadequate methods and techniques, his opinion that the chair bracket was defective and caused the injury cannot be presented to the jury.
In his Rule 26(a)(2) report, Thompson concludes that “[t]he chair was found to have a severe fracture of the bracket that attached the seat to the chair base. The failure of this bracket would have caused the accident to McCreless .... ” Having conducted no analysis beyond making a visual assessment of the chair’s post-break components and taking measurements of the broken parts and the fall rate of the unserviceable piston, Thompson offers three separate opinions on causation. The admissibility of these opinions will be addressed in succession.
A. The failure of the seat bracket caused the seat to tilt down and drop. This movement would cause the chair to shoot backwards as the seat fell downward.
The seat tilted approximately 11 degrees when the bracket broke. An 11 degree tilt would cause 20% of the occupant’s weight to push the seat backwards. For a 180 pound person, this is equivalent to pushing the chair backwards with a force of 37 pounds. Since the chair is on casters/wheels, a 36 pound force causes the chair to shoot backwards. This wasevident during the inspection of the chair when a foot had to be put against the caster to prevent it from sliding backward when someone sat in the chair to measure the pneumatic piston fall rate.
This proposed testimony cannot be allowed into evidence because it would not assist the trier of fact and because Thompson is not qualified to give a critical portion of the said opinion. There is no dispute that the bracket attaching the piston to the seat of the chair in which McCreless attempted to sit was, in fact, fractured. But the mere fact that the bracket was broken, without any evidence as to when it broke or what actually caused it to break, cannot provide a basis for establishing liability on the part of defendants or either of them.
See Emody v. Medtronic, Inc.,
Second, if the court assumes the relevance of Thompson’s testimony that the failure of the bracket caused the seat to tilt and drop, causing the chair to shoot backwards as the seat fell downward (something which the court cannot assume, for the reasons discussed in the preceding paragraph), Thompson is not qualified to offer this opinion.
See Rink,
B. A main cause of the seat bracket failure was the poor manufacture method used for making the bracket. A crease/seam was pressed into the bracket which weakened the bracket and allowed cracks to form in the crease/seam. The cracks formed in the crease/seam and followed the seam/crease around the center hub. Ample evidence was found, as discussed in the section on seat bracket failure, to tie the facture [sic] of the bracket to the manufacture method. The bracket was made by a stamping process. This is where a piece of sheet metal is put into a press that contains a die or series of dies that cut and shape the piece of sheet metal into the desired shape. The same equipment is used to punch holes in the sheet as used to push a shape such as the dome to which the pneumatic piston connects. One difference between the punch to make a hole and the die to push up the dome is the shape and edges of the die pieces. It appears thatone side of the die had an edge which was too sharp and damaged the metal.
Thompson’s second opinion must also be excluded because, as the court has previously indicated, the methods and procedures used to reach this conclusion were not sufficiently reliable. The “section on bracket failure,” which Thompson incorporates by reference in his second opinion, states in its entirety:
The seat bracket shown in picture 027 was broken in such a way to allow the seat to tilt forward as seen in picture 045. The bracket as seen in pictures 076 and 087 was torn downward at the front edge of the seat bracket. The bracket was manufactured by a stamping process using a sheet metal steel. The stamping process that was used raised a dome at the center where the pneumatic piston release button is located. This part of the stamping was done at the center where the pneumatic piston release button is located. This part of the stamping was done in such a way as to produce a crease/seam in the metal seen in picture 085. The crease/seam was a location of weakness which allowed cracks to form in the crease as seen in picture 089. It is evident from pictures like 084, 087 and 089 that the crease/seam in the stamping was a significant contributing factor in the failure of the bracket.
As Thompson’s report clearly admits, the procedure he followed in reaching his second opinion consisted of nothing more than visual analyses and physical measurements of the broken seat components. He never applied force to the crease/seam on an identical chair to test its breaking point. The court reiterates the non-exhaustive set of guidelines that district courts must use when determining whether an expert’s methods are reliable: (1) whether the theory or technique can and has been tested; (2) whether the theory or technique has been subjected to peer review in publications; (3) the known or potential rate of error of the theory or technique; and (4) whether the theory or technique is generally accepted as reliable by the relevant scientific community.
Daubert,
Thompson explains that “it appears that one side of the die had an edge which was too sharp,” but he did not compare the actual die that was used to fabricate the bracket used in the chair at issue to a different die used in the same or a similar process (emphasis added). He did not compare two brackets made using different shapes or types of die. For aught appearing, Thompson never even looked at or attempted to look at the actual die that he says caused a manufacturing defect in the failed bracket. His approach has not been subjected to the review of any of his peers. As the proponent of the proposed testimony, McCreless bears the burden of showing that Thompson’s investigative techniques are reliable.
Williams,
C. Several alternative designs would have prevented the failure of the bracket and the ensuing accident. These are in order of preference: 1. eliminate the design of the stamped dome shape and use a box with a center hole design, 2. use a die design that does not thin, stretch, or crease the metal at the junction of the pneumatic piston to the seat, 3. increase the thickness of the bracket sheet metal so that it can carry more stress. Alternative designs are available that increase the strength of the broken joint significantly. The first alternative is to use a box with a hole. The pneumatic piston comes up through the hole and attaches at the top of the box. One problem with the dome design used in the broken chair is that when a person sits in the seat the bracket gets heavily loaded at the front edge of the dome causing it to crack. The box design distributes the load more evenly along the edges of the box and through the top of the pneumatic piston. This design is used on many drafting and lab chairs. The second alternative would remove the defect in the stamped bracket and thus strengthen it. The third alternative is to use a thicker piece of steel for the bracket. The increased thickness will offset strength lost to defects in the stamping process. If the stamping is done properly the increased thickness will help offset the design drawbacks of the dome shaped connection between the pneumatic piston and the seat.
Thompson’s opinions regarding alternative designs may very well be correct, as may be his other alternate opinions. Under
Daubert,
however, this court does not itself simply agree with or disagree with Thompson’s conclusions. It instead focuses on the methods Thompson used to reach his conclusions.

Senn v. Carolina Eastern, Inc.,
Defendants’ Motion for Summary Judgment
McCreless relies on the tort theories of the AEMLD, negligence, and wantonness. 3 In Brooks v. Colonial Chevrolet-Buick, Inc., the Alabama Supreme Court explained:
We recognize that Sears, Roebuck & Co. v. Haven Hills Farm, Inc., supra [395 So.2d 991 (Ala.1981)], does not stand for the proposition that expert testimony is always required in such cases; however, it does stand for the proposition that because of the complex and technical nature of the product and in order to present evidence from' which a lay jury may reasonably infer that a defective condition of the product was the cause of the product’s failure and the cause of the resultant injury to the plaintiff, expert testimony is usually essential and, therefore, usually required. If, however, under all the attendant circumstances, absent expert testimony, the jury could reasonably infer from the product’s failure of performance that a defective condition caused the injury, a prima facie case has nonetheless been established. Sears, Roebuck & Co. v. Haven Hills Farm, Inc., supra.
Conclusion
Under Daubert, even, the most distinguished scientist or engineer must strictly adhere to the rigors of the scientific method. And the trial court, no matter how esoteric or difficult the subject, must understand it sufficiently well to dissect and critique an expert’s proffered opinion. Daubert endows the trial court with that obligation, and ostensibly with the wisdom to discharge it. The trial court does not have to find an expert to be a charlatan or a fool to keep the gate shut on him. The trial court opens the gate only if the scientific method has been totally complied with. If Thompson’s proffered expert opinion is infected with faulty or unreliable methodology, even if otherwise plausible, it must be excluded. After applying Daubert principles to Thompson’s opinions, the court reaches the conclusion that his testimony is methodologically unsound, is subject to too many scientific shortcomings, and must therefore be excluded.
By separate order, the court will grant defendants’ motion to exclude Thompson’s testimony. Because this ruling will leave McCreless with no evidence to prove that her injuries were caused by any tortious act or omission of either defendant, defendants’ motion for summary judgment will also be granted. The court will also grant defendants’ motion to strike Thompson’s supplemental report under Rule 37(c), Fed.R.Civ.P., because McCreless did not tender that report in a timely manner in accordance with Rule 26(a)(2) and the scheduling order entered in this case.
Notes
. Rule 702, Fed.R.Evid. states:
If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.
. Scientifically valid evidence does not necessarily reflect the ultimate truth. The ultimate veracity of evidence is to be determined at trial. Two experts can disagree and yet both be allowed to testify if they both pass the Daubert test.
. McCreless's complaint also lodges additional claims under theories of failure to warn, breach of contract, and breach of warranty. McCreless does not dispute that defendants are entitled to summaiy judgment on these additional claims.
