Representative Matters

Distinctions

Michael represents both public and private parties in connection with drafting of contracts, bid issues and dispute resolution in a wide variety of construction matters. He has assisted a successful bidder in defending a challenge to a public bid for the purchase of municipal property, ultimately obtaining a written apology as well as a six-figure settlement for a vexatious litigation claim arising from the challenge.

Michael has represented owners in connection with the construction of power plants, and contractors in international arbitration over the development of a solar facility. He has tried jury and courtside cases, as well as handled appeals, arbitration and mediation. Notably, he successfully defended a $3 million mechanics’ lien case in Federal Court. In addition to obtaining a defense judgment on the claim, he also obtained a decision in the client’s favor for more than $1 million on a counterclaim.

In addition to construction work, Michael also represents both for profit and nonprofit entities in litigation. He also represents clients with respect to information security issues, including defense of a class action under the TCPA.
