CA AB615

Expands the definition of written arbitration agreements to include electronic communications (email, data messages) if the information is accessible for subsequent reference.

Defines "interim measure of protection" as temporary orders an arbitral tribunal may grant to maintain status quo, prevent harm to the arbitral process, preserve assets, or preserve evidence pending final dispute resolution.

Requires parties requesting interim measures to demonstrate irreparable harm that substantially outweighs harm to the opposing party and a reasonable possibility of succeeding on the merits, except for evidence preservation requests.

Allows parties to request preliminary orders without notice to the other party if disclosure would frustrate the measure's purpose; preliminary orders expire after 20 days unless replaced by an interim measure after the other party is heard.

Specifies that interim measures issued by arbitral tribunals are final and binding, may be enforced in superior court, and establishes limited grounds for courts to refuse recognition or enforcement.
