The bulk of these cases fall into three categories. First, Marcus has won precedent-setting drowning and swimming-related cases involving the negligence of third parties and the government. Second, he has handled building collapse and construction and design related claims. Third, he has substantial experience litigating and trying premises liability for criminal attack cases.
