Representative Matters

  • Defended a food processing company in an arbitration proceeding involving several real estate issues between adjoining land owners. Obtained a defense arbitration award of zero dollars in the client's favor when the claimant sought over $1.3MM, and obtained a full award of damages on our client's counterclaim.  

  • Represented a business broker who was denied his commission despite his role in effectuating the sale of a multimillion-dollar waste hauling business. After a hotly contested proceeding, we successfully negotiated a very favorable resolution for our client.

  • Represented a large commercial retail operation in an easement dispute between property owners in a large mall development. Our representation included argument before the Michigan Court of Appeals, who reversed the trial court's summary disposition ruling against our client, and instead, entered a summary disposition order in our client's favor.

  • Represented several insurance companies in numerous coverage dispute matters where millions of dollars of claims were asserted. We successfully obtained summary disposition rulings in favor of our clients. One such matter was the Dow Corning breast implant coverage litigation in which over $200MM in claims were asserted against numerous insurers. We acted as lead counsel in developing and implementing crucial litigation strategies that resulted in the court ruling in favor of our client in limiting the client's exposure, which lead to a very favorable settlement for our client.
