Facebook was ordered to pay $650 million Friday for running afoul of an Illinois law designed to protect the state’s residents from invasive privacy practices.

That law, the Biometric Information Privacy Act (BIPA), is a powerful state measure that’s tripped up tech companies in recent years. The suit against Facebook was first filed in 2015, alleging that Facebook’s practice of tagging people in photos using facial recognition without their consent violated state law.
