- Additionally, video of the incident was used to demonstrate that the plaintiff had actual/constructive knowledge of spilled water in the premises but proceeded to walk in that area anyway
- Forty percent comparative negligence was assigned to the plaintiff, and despite the plaintiff’s introduction of the medical cost projection described above, only $50,000 in future medical care was awarded by the jury
- The total award, after a molded verdict, was $118,800, which our client viewed as a victory in this venue
- Real estate agency dismissed from litigation
- The defense prevailed on a motion to dismiss our real estate agency client
- The plaintiff filed counts of fraud, deceit, misrepresentation, conspiracy, conversion, invasion of privacy-false light, breach of contract, and promissory estoppel against the agency regarding an allegedly fraudulent transfer of a private residence by the co-defendant seller of the property
