Google has been sued in a class action alleging that it illegally eavesdropped on Home Depot customer service calls via its artificial intelligence service, Cloud Contact Center AI.

Bursor & Fisher and the Simon Law Firm filed the complaint on Thursday in the U.S. District Court for the Northern District of California. According to the claim, Google’s use of the AI product, developed in 2022 to automate and fine-tune businesses’ customer service interactions, violated Section 631 of the California Invasion of Privacy Act, which prohibits wiretapping. The plaintiff and class members could be awarded $5,000 per violation under CIPA.
