The New Jersey Attorney General’s Office is getting an earful of complaints over its request that the Supreme Court name a special master to consider relaxing the rules for calibration of the Alcotest 7110 MKIII-c, which is used to estimate from a breath test the blood-alcohol level of persons suspected of drunken driving.

The state is asking the court to eliminate a requirement set forth in the decision State v. Chun that the thermometer used to check simulator solution temperatures before each calibration of the Alcotest should conform to standards of the National Institute of Standards and Technology. But the New Jersey State Bar Association and some defense lawyers disagree with the state’s motion to have the court appoint a special master.
