Authorizes the vacating of an arbitration award on the basis of arbitrator disregard of the law

This bill adds a new legal standard allowing courts to overturn (vacate) arbitration awards when arbitrators "evidenced a manifest disregard of the law." It directly affects parties involved in arbitration disputes who believe an arbitrator ignored applicable legal rules in their decision. The key provision amends state law to explicitly include "manifest disregard of the law" as a valid reason for vacating an award, alongside existing grounds like procedural errors. This change provides a clearer legal pathway for challenging arbitration outcomes based on legal errors, rather than just procedural flaws.
