Legal Malpractice Lawsuit Successfully Resolved at Trial. LMM Partner Mike McDonald recently represented a highly experienced attorney against a multimillion-dollar legal malpractice lawsuit. In what was a very challenging case involving admitted liability and significant claimed damages, Mike focused on attacking the plaintiff’s claims in expert discovery, through aggressive pre-trial motions to exclude key evidence and witnesses, and through effective jury selection to posture the case for a remarkably successful resolution on the third day of trial.

Favorable Defense Verdict Against Brain Injury Claim. Mike was part of the trial team defending a large public entity in a personal injury lawsuit involving an alleged traumatic brain injury sustained in a car accident. In a difficult case involving admitted fault and a multi-million-dollar claim, Mike tailored his opening statement, cross-examination of key witnesses and closing argument to successfully refute the opposing counsel’s damages contentions. The jury agreed with Mike and awarded the exact damages figure that he proposed at closing, which amounted to approximately 1% of Plaintiff’s alleged damages.

Successful Application of Design Professional “Completed and Accepted” Defense. In a successful application of the “completed and accepted” doctrine, Mike and the LMM team successfully defeated a contentious personal injury case involving professional negligence. Agreeing that the subject condition giving rise to the alleged injury was completed and accepted by the owner before the subject incident occurred, the court granted LMM’s Motion for Summary Adjudication and dismissed the plaintiff’s professional negligence cause of action. Mike was then able to leverage the successful ruling into a complete dismissal with prejudice of the plaintiff’s action against the client.

Dismissal of Cross-Complaint against Engineer. Mike represented a structural engineering client sued by the architect on a cross-complaint in a multi-million-dollar dispute related to a public works project in Santa Barbara County. After a multi-state investigation into the architect, LMM determined that the architect had failed to maintain its ability to transact business in California, had been dissolved in the state where it was formed, and thus had no standing to sue LMM’s client. Through novel motion practice, first to dismiss the architect’s cross-claims, then to dismiss the intervening insurer’s claims, LMM secured orders dismissing the case entirely as to their client.
