Indiana’s Supreme Court has ruled that the Fifth Amendment allows a woman accused of stalking to refuse to unlock her iPhone. The court held that the Fifth Amendment’s rule against self-incrimination protected Katelin Seo from giving the police access to potentially incriminating data on her phone.

The courts are divided on how to apply the Fifth Amendment in this kind of case. Earlier this year, a Philadelphia man was released from jail after four years of being held in contempt in connection with a child-pornography case. A federal appeals court rejected his argument that the Fifth Amendment gave him the right to refuse to unlock hard drives found in his possession. A Vermont federal court reached the same conclusion in 2009—as did a Colorado federal court in 2012, a Virginia state court in 2014, and the Massachusetts Supreme Judicial Court in 2014.
But other courts in Florida, Wisconsin, and Pennsylvania have reached the opposite conclusion, holding that forcing people to provide computer or smartphone passwords would violate the Fifth Amendment.
Lower courts are divided about this issue because the relevant Supreme Court precedents all predate the smartphone era. To understand the two competing theories, it’s helpful to analogize the situation to a pre-digital technology.
Suppose that police believe that a suspect has incriminating documents stored in a wall safe, so they ask a judge to compel the suspect to open the safe. The constitutionality of this order depends on what the police know.
If the government can’t show that the suspect knows the combination—perhaps the suspect claims the safe actually belongs to a roommate or business partner—then all courts agree that forcing the suspect to try to open it would be unconstitutional. This is because the act of opening the safe functions as an admission that the suspect owns the safe and the documents inside of it. This fact could be incriminating independent of the contents of any documents found inside the safe.
On the other hand, if the government can show that the suspect knows both the password and which specific documents are in the safe—perhaps because the suspect described the safe’s contents during an interrogation—then all courts agree that the suspect can be forced to open the safe. That’s because the Fifth Amendment is a right against self-incriminating testimony, not the production of incriminating documents.
But what if the state can show the suspect knows the combination but doesn’t know which documents are in the safe? Here the courts are split.
One theory holds that only the act of opening the safe is testimonial. Once the safe is open, the safe contains whatever documents it contains. The police get the information in the documents directly from the documents, the same as they would i
