Challenging the Reliability of SCRAM Alcohol Monitor Bracelets

Prison gate icon
Advising criminal defense attorneys about the science behind SCRAM bracelet technology, including potential discovery and reliability issues.

The SCRAM Continuous Alcohol Monitoring bracelet is an ankle monitor worn 24 hours a day that claims to test the wearer’s perspiration for consumption of alcohol. It is widely used as a condition of release for individuals charged with or convicted of driving-while-intoxicated offenses. As part of its criminal justice and civil liberties work, the Samuelson Clinic helps criminal defense attorneys challenge the reliability and sufficiency of SCRAM evidence used to support an alleged violation of a no-drinking condition. This work includes the preparation of template motion materials and affidavits. We are available to consult and co-counsel on SCRAM-related issues, so please reach out.

Samuelson Clinic Fellow Julie DeVries authored an article in the NACDL publication The Champion outlining ideas for how criminal defense attorneys can go about challenging the use of this technology in their cases. We also provide other public resources below.
