SAN FRANCISCO — The judge overseeing a proposed $550 million settlement that Facebook Inc. reached to settle claims that its “tag suggestions” feature violated an Illinois biometric privacy law has asked lawyers in the case to provide detailed explanations of why the deal would pay class members less than statutory damages amounts.

U.S. District Judge James Donato of the Northern District of California noted at a case management conference Thursday that the Illinois Legislature set statutory damages at $1,000 for negligent violations of the state’s Biometric Information Privacy Act and $5,000 for intentional or reckless violations. Plaintiffs sued in 2015, claiming that the social media platform’s “tag suggestions” feature, which prompts users to identify “friends” in photographs posted to the site, violated BIPA.
