    Loryn Riggiola, Partner, Zetlin & De Chiara LLP,  joins a panel on June 10, 2021, 1:30-2:30 entitled Understand the Arbitral Decision-Making Model and What Advocates Can Do to Protect the Award. This panel will dicuss the differing arbitral decision-making philosophies and recent challenges to arbitral awards. The application of law, equity, fairness, and justness can serve as a means by which an arbitrator can reach a decision. Each model has its own unique characteristics, and understanding these approaches and their limits is key to avoiding improper or frustrating outcomes in arbitration. Along with the arbitrator, advocates have a role to play in the rendering of an enforceable award, and all participants should have an appreciation for the nature of recent challenges to arbitral awards. The panel will also offer practical tips for drafting arbitration agreements, conducting discovery, and the presentation of evidence to assist arbitrators in making enforceable awards.

    Summer turned up the heat at Zetlin & De Chiara LLP where we were involved in two of the most prominent construction cases in the nation. With attorneys airborne between the East and West Coasts, the office has been busy on the ground with client matters, fielding questions from the press, speaking at industry events and supporting community and professional organizations. Even as the temperature outside cools, our high level of activity shows no signs of chilling.
