The police were hunting an armed bank robber and had no suspect, so they asked Google for one. A geofence warrant pulled every phone that had been near the bank; a three-step narrowing produced a name — Okello Chatrie, who had opted in to let Google log his location every few minutes — and he drew twelve years. On Monday the Supreme Court ruled, 6–3, that reaching into his location history was a search the Fourth Amendment governs. The outcome is a win for privacy. The reasoning is the bigger story.

The government's defense rested on a premise the Court has propped up for half a century: what you hand to a company, you have handed to the state. Here it wore modern clothes. Chatrie opted in. He knew, the argument went, that police might one day ask Google for the data — so his movements were no longer his. Justice Elena Kagan's majority didn't just reject that. It turned the premise inside out. The ubiquity the government offered as proof of consent — everyone carries a tracked phone, everyone taps allow — is the very thing that makes the consent impossible.

Start with how the allow gets tapped. Google, the majority noted, repeatedly prompts users to switch location on, often warning that the device will not "work correctly" otherwise — while never saying how often it would record them, how precisely, or that the record could be passed to the government. That is not a negotiation. It is the price of a working phone.

A cell-phone user is not to be viewed as sharing private information with third parties—which then can be freely passed on to the government—just by doing the ordinary things cell-phone users do.

The logic cuts past geofencing. When a practice is universal and effectively mandatory, treating participation as a waiver doesn't trim privacy at the margins — it voids it wholesale, for everyone at once. You cannot opt out of modern life to keep a right the Constitution already granted you. And the stakes aren't abstract: even short-term location data, Justice Sotomayor noted in a line the majority quoted approvingly, reveals "a wealth of detail about [a person's] familial, political, professional, religious, and sexual associations" — the clinic, the lawyer's office, the house of worship.

A click you can't refuse and still use your phone was never a choice. A billion of them was never a billion waivers.

Justice Samuel Alito, in dissent, is not wrong that this is disruptive. He warns the majority has unleashed "upheaval" in Fourth Amendment law, would have preferred an app-by-app standard, and asks pointedly which side a payment service like Apple Pay falls on. Concede it: the majority drew a bright line where the old doctrine wanted gradations, and bright lines are blunt. But the app-by-app alternative isn't nuance — it's the consent fiction in finer print. It would make your constitutional protection turn on which permission screen you happened to tap, which is exactly the move the Court refused. Gradation, here, is how the dragnet survives.

And it does survive, in part. The Court stopped short of striking geofence warrants down as inherently unconstitutional; the Electronic Frontier Foundation applauded the decision while noting exactly that. Police can still go to Google — they now need a genuine warrant and genuine cause first, and whether this particular search was reasonable goes back to the lower court. The dragnet didn't die Monday.

The fiction under it did. The surveillance economy's quiet legal cushion has always been that consent scales — that enough forced clicks accumulate into something like agreement. Six justices said a thing nobody could refuse was never the thing everybody surrendered. The warrant lives. The premise that we signed it away is gone.
