Judge Rules That Unlocking Cellphones via Fingerprint Does Not Violate Constitutional Rights

Wow — hope that folks at Apple, Samsung, Motorola, etc. see this.


In response to an incident that lacked any relation to the last fingerprint-related news, a Minnesota court ruled against a recent Fifth Amendment appeal regarding device passwords. The Minnesota Court of Appeals ruled that ordering an individual to unlock a device with a fingerprint “is no more testimonial than furnishing a blood sample, providing handwriting or voice exemplars, standing in a lineup, or wearing particular clothing.”

The case in question involved Matthew Vaughn Diamond, a man Carver County District Court found guilty in 2015 of burglary and theft, among other crimes. Other news outlets cite arrest records from far before 2015, but the records showed no relevance to the January 2017 ruling. The Carver County District Court fought Diamond over his phone’s contents—he locked the phone with a fingerprint and refused to unlock the phone for the court. He argued, initially, that forcing his fingerprint violated both his Fourth and Fifth Amendment rights. However, the Minnesota Court of Appeals heard only the Fifth Amendment appeal.

According to the Fifth Amendment, compelled self-incrimination is a violation of human rights. “The Supreme Court has held that ‘a witness may have a reasonable fear of prosecution and yet be innocent of any wrongdoing. The privilege serves to protect the innocent who otherwise might be ensnared by ambiguous circumstances’.” Additionally, the “right to remain silent” from the Miranda Rights, read to an arrestee at the time of arrest, granted a suspect the ability to refuse questions. Additionally, at the minimum, gave suspects the right to avoid answering questions legally and without fear of immediate repercussions.
