In December, 2008, the State of Ohio used a federal grant of $7 million for the purchase of 710 portable breath test (PBT) machines in spite of warnings that the machines were unreliable and subject to legal challenge.
The machines have proven to be vulnerable to errors based on environmental factors including heat and cold, as well as variable such as the length of time a suspect blows into the device.
Undaunted, The Ohio Department of Health began distributing the machines to rural counties hoping to avoid legal challenges by having the machines used in areas of Ohio having less than 3% of the state’s population.
Lawyers in several other states have gotten thousands of convictions thrown out because the manufacturer of the machine, CMI, Inc. of Kentucky refuses to turn over details of the machine’s operations.
But in Ohio, it appears the device will need to be challenged on other grounds due to the fact that a 1984 ruling by the Ohio Supreme Court barred defendants from attacking the reliability of breath tests once they’ve been certified by The Ohio Department of Health. On the other hand, no device may be used in Ohio unless it appears on the Federal List of Approved Breath Evidential Instruments and the ISP approved list of Devices. PBT’s are generally not on the list.
Meanwhile the state continues to put more instruments in the field - slowly. Just 17 out the of 714 original purchased have been used.
Stay tuned!
