Representative Matters

  • Represented the Goldfield Corporation (a provider of electrical construction and maintenance services in the energy infrastructure industry) in its $7.25 million acquisition of C and C Power Line, Inc. (a full service, union electrical contractor).
  • Obtained on behalf of a national satellite television installer and service provider a ruling for the client on all fourteen counts, alleging violations of the National Labor Relations Act (NLRA), arising out of the client's withdrawal of recognition of a union at one of their major facilities in Florida.
  • Obtained a decision from the Florida Third District Court of Appeal reversing a $1 million jury verdict in favor of a former television reporter in her age and sex discrimination suit. Sunbeam Television Corp. v. Mitzel (Fla. Dist. Ct. App. 3d Jan. 18, 2012).
  • Obtained decision from the U.S. District Court for the Southern District of Florida on behalf of a real estate developer that vacated a judgment in favor of the plaintiff in a Title VII discrimination and retaliation case and dismissed the plaintiff’s claims due to her failure to disclose her bankruptcy filing to the court, and her failure to disclose her Title VII case to the bankruptcy court.
  • Obtained a decision from the National Labor Relations Board affirming an administrative law judge's decision that the client had not engaged in unfair labor practices by terminating the employment of three employees because they were terminated for their conduct at work rather than their pro-union activities.
