The injury at the center of the recently-decided Stuhlmacher v. Home Depot U.S.A., Inc. didn't occur around the holidays. However, it is relevant because it involves an allegedly defective ladder. The fact is, both before and for weeks after the holiday season, people climb ladders to decorate and then "un-decorate" their homes.
It's a fact that ladders can tip regardless of their condition if they aren't used properly. However, when a ladder collapses or otherwise fails when being used properly as intended or anticipated, this may be grounds for a product liability lawsuit.
This was the case in Stuhlmacher.
Generally in order to succeed in a product liability lawsuit, one must prove not only he or she suffered injuries, but that those injuries were proximately caused by a product that was either defective or lacked proper instructions or warnings. One must also show the product was being used more or less in the manner intended.
Here, according to court records, the issue before the U.S. Court of Appeals for the Seventh Circuit was that of causation, as posited by a plaintiff expert witness, whose testimony was stricken from the record by the trial judge. Without that testimony, causation could not be proven. The federal appellate court reversed, finding the testimony qualified as relevant under Civil Rule 702, so long as it helps the jury in determining any fact at issue in the case. Specifically, expert witnesses are allowed to put forth alternative models to explain their conclusions, the court ruled.
