This case is interesting because it dismisses a legal malpractice claim because the expert did not reveal how the negligence of the attorney caused the injury of the plaintiff. The opinion does not shed as much light on the facts of the case as I would like it to. However, the opinion does explain that although plaintiff had an expert and the expert prepared a report, the expert did not sufficiently explain proximate causation. Proximate causation is a difficult concept for nonlawyers to understand. Indeed, sometimes lawyers do not understand it.
In sum, the expert report said the lawyer was negligent but it failed to explain why the negligence caused the bad result that the plaintiff received. The opinion, though it is based on Minnesota law, is consistent with the modern trend in the cases which requires expert reports to be more complete.
