A California judge has ruled that American cops can’t force people to unlock a mobile phone with their face or finger. The ruling goes further to protect people’s private lives from government searches than any before and is being hailed as a potentially landmark decision.
Previously, U.S. judges had ruled that police were allowed to force unlock devices like Apple’s iPhone with biometrics, such as fingerprints, faces or irises. That was despite the fact feds weren’t permitted to force a suspect to divulge a passcode. But according to a ruling uncovered by Forbes, all logins are equal.
The order came from the U.S. District Court for the Northern District of California in the denial of a search warrant for an unspecified property in Oakland. The warrant was filed as part of an investigation into a Facebook extortion crime, in which a victim was asked to pay up or have an “embarassing” video of them publicly released. The cops had some suspects in mind and wanted to raid their property. In doing so, the feds also wanted to open up any phone on the premises via facial recognition, a fingerprint or an iris.
While the judge agreed that investigators had shown probable cause to search the property, they didn’t have the right to open all devices inside by forcing unlocks with biometric features.
On the one hand, magistrate judge Kandis Westmore ruled the request was “overbroad” as it was “neither limited to a particular person nor a particular device.”
But in a more significant part of the ruling, Judge Westmore declared that the government did not have the right, even with a warrant, to force suspects to incriminate themselves by unlocking their devices with their biological features. Previously, courts had decided biometric features, unlike passcodes, were not “testimonial.” That was because a suspect would have to willingly and verbally give up a passcode, which is not the case with biometrics. A password was therefore deemed testimony, but body parts were not, and so not granted Fifth Amendment protections against self-incrimination.
