- Whistleblowing Defense. Settled a potential large whistle-blower lawsuit on behalf of an addiction treatment facility. In addition to potential false claims act violations, a former employee alleged a hostile work environment (constructive discharge) and retaliation. Sensing an opportunity with an eager plaintiff, Nelson Hardiman proposed an unusual pre-filing mediation, which resulted in a quick settlement for a fraction of the original demand amount.
- Represented bariatric surgeon in bringing contract, tort, and Labor Code claims against former employer/medical practice represented by litigation department chair for national law firm. After five-day arbitration, awarded 100% of unpaid wages, interest, civil penalties, and attorneys’ fees.
- Represented IPA in five-year action against laboratory, defending against numerous claims and legal theories seeking in excess of $1,500,000 for lab testing performed after termination of the parties’ agreement. Following five days of arbitration, arbitrator dismissed all but one claim, reducing potential exposure to a fraction of the claimed amount.
- Represented ambulatory surgery center in out-of-network “fee forgiveness” action against major insurance company. Pursuing in excess of $3,000,000 for claims improperly denied based on claim that surgery center “forgave” patient contribution as inducement for using out-of-network facility. Obtained successful rulings on: motion to remand from Federal Court, demurrers, motions to compel discovery.
- Litigation: The father of a teenager being treated for addiction wrongfully pocketed more than $100,000 in insurance proceeds to buy a house instead of reimbursing a recovery facility. On behalf of the facility, Zach filed multiple actions against the father including for unjust enrichment and fraud. The case was further complicated by the fact that the father never signed any contracts with the rehab facility and worked out of state. However, Zach was able to serve the defendant through some unique sleuthing efforts and dogged determination. In the end, he won a full judgment plus interest against the father.
- Representing nurse in pre-litigation efforts to resolve dispute with former physician-employer alleging misappropriation of trade secrets, fraud, and unfair competition based on nurse’s communications with patients announcing her departure.
