A spokeswoman for District Attorney Seth Williams said Thursday the office decided to perform a wholesale review of cases from September 2009 to November 2010 because of faulty breath tests.
A day earlier, Williams and police Commissioner Charles Ramsey said the improperly calibrated machines affected about 1,150 DUI cases. City police file thousands of DUI cases each year.
The district attorney's office says no defense attorneys have thus far requested a new trial or a dismissal of charges. Spokeswoman Tasha Jamerson says the office will also do its own calibration checks on machines rather than relying only on police certifications.
