The court ordered a review of the computerized Alcotest 7110 in 2005 after a trial court and an appeals court questioned whether it was reliable enough to be admissible in court, The (Newark, N.J.) Star-Ledger reported Monday.
More than 10,000 driving under the influence convictions obtained using Alcotest results as evidence were suspended pending the result of the review and the finding of the Supreme Court.
"We are confident, based on this far-reaching and searching inquiry, that the device is sufficiently reliable so that the rights of all defendants have been protected," Justice Helen Hoens wrote for the unanimous court. "The device, with the safeguards we have required, is sufficiently scientifically reliable that its reports may be admitted in evidence."
