New York Court of Appeals
The People of the State of New York v. Raymond A. Campbell, Respondent the People of the State of New York v…
May 11, 198973 N.Y.2d 481
Summary
The Court held that blood alcohol test results from the DuPont Automatic Clinical Analyzer are not admissible per se and require a foundation showing the machine's accuracy, which the People failed to provide; additionally, a guilty plea forfeits the right to appellate review of evidentiary errors, so the reversal of a conviction on that ground was improper.
