Montana has done something that many states and the United States Congress have debated but failed to do: it has just enacted the first attempt to close the dreaded, invasive, unconstitutional, but easily fixed “data broker loophole.” This is a very good step in the right direction because right now, across the country, law enforcement routinely purchases information on individuals it would otherwise need a warrant to obtain.

What does that mean? In every state other than Montana, if police want to know where you have been, rather than presenting evidence and sending a warrant signed by a judge to a company like Verizon or Google to get your geolocation data for a particular set of time, they only need to buy that same data from data brokers. In other words, all the location data apps on your phone collect —sometimes recording your exact location every few minutes—is just sitting for sale on the open market. And police routinely take that as an opportunity to skirt your Fourth Amendment rights.

Now, with SB 282, Montana has become the first state to close the data broker loophole. This means the government may not use money to get access to information about electronic communications (presumably metadata), the contents of electronic communications, contents of communications sent by a tracking devices, digital information on electronic funds transfers, pseudonymous information, or “sensitive data”, which is defined in Montana as information about a person’s private life, personal associations, religious affiliation, health status, citizen status, biometric data, and precise geolocation. This does not mean information is now fully off limits to police. There are other ways for law enforcement in Montana to gain access to sensitive information: they can get a warrant signed by a judge, they can get consent of the owner to search a digital device, they can get an “investigative subpoena” which unfortunately requires far less justification than an actual warrant.

Despite the state’s insistence on honoring lower-threshold subpoena usage, SB 282 is not the first time Montana has been ahead of the curve when it comes to passing privacy-protecting legislation. For the better part of a decade, the Big Sky State has seriously limited the use of face recognition, passed consumer privacy protections, added an amendment to their constitution recognizing digital data as something protected from unwarranted searches and seizures, and passed a landmark law protecting against the disclosure or collection of genetic information and DNA. 

SB 282 is similar in approach to  H.R.4639, a federal bill the EFF has endorsed, introduced by Senator Ron Wyden, called the Fourth Amendment is Not for Sale Act. H.R.4639 passed through the House in April 2024 but has not been taken up by the Senate. 

Absent the United States Congress being able to pass important privacy protections into law, states, cities, and towns have taken it upon themselves to pass legislation their residents sorely need in order to protect their civil liberties. Montana, with a population of just over one million people, is showing other states how it’s done. EFF applauds Montana for being the first state to close the data broker loophole and show the country that the Fourth Amendment is not for sale.
