20-CV-1874 Leibfried v. Caterpillar, Inc.
Decision and Order
An expert cannot offer new opinions at a deposition or in an affidavit submitted in response to a motion to exclude. An expert’s opinions must be included in an expert report. A psychologist’s recollection of what his patients told him about the emotions they felt in the moments when they believed they were about to die is not a sufficient basis for the psychologist to offer an opinion about what the plaintiff felt in the minutes before he died.
