How do you fight the Plaintiff committing fraud in a unlimited injury civil case?

To combat a Plaintiff committing fraud in an unlimited injury civil case, gather substantial evidence that contradicts their claims, such as documents, witness testimonies, and expert analysis. File motions to dismiss or for summary judgment if the evidence clearly shows the fraud. Additionally, consider counterclaims or seeking sanctions for fraudulent behavior. It's crucial to maintain a strong narrative and present a compelling case to the court.
