  • Lead associate in the defense of a global tool and die manufacturer in litigation regarding a claim of $7.5 million in alleged unpaid commissions. The litigation involved lawsuits filed in Ohio and Michigan. Zach’s responsibilities included drafting all briefs and dispositive motions, including briefing before the Michigan Court of Appeals. In large part due to Zach’s efforts, the client obtained dismissal of the Michigan lawsuit, which was upheld on appeal. After a two-year battle involving significant motion practice, including successfully opposing a summary judgment motion filed by the claimants, the Ohio lawsuit was eventually settled to the client’s satisfaction.
  • Key member of litigation team representing plaintiffs in a breach of contract lawsuit against a homebuilder for failure to return the down payment on a $2.325 million home building contract. Zach’s briefing resulted in the clients obtaining summary judgment against the home builder on the breach of contract claim (as well as dismissal of all of the homebuilder’s counterclaims), resulting in a $103,000 judgment for Zach’s clients.
  • Lead associate in the representation of a national motion picture exhibition chain in the defense of a $360,000 breach of contract lawsuit with a local commercial landlord.
