Proximate causation is often the issue that defeats a legal malpractice case. In this case, even though a law firm failed to timely appeal an interlocutory ruling, there was no malpractice because the ruling was correct. Thus, even if the appeal had been filed on time, the plaintiff would have lost the case anyway.
The underlying case was litigated in the courts of the State of Oregon. Here, the plaintiff hired a law firm to give an opinion on whether an adverse ruling in a case could be appealed. The law firm essentially said that the ruling was interlocutory and that no appeal could be taken until the entire case was completed. To complete the case the plaintiff dismissed its remaining claims and appealed. The appeal was, however, dismissed because it was not timely.
Plaintiff then sued the law firm alleging that the law firm gave incorrect advice on the appeal deadline. The trial court granted summary judgment for the law firm. It held that plaintiff could not establish proximate causation, that is, but for the negligence, plaintiff would have obtained a better result in the underlying lawsuit.
