On December 31, 2012 Dauphin County Judge Lawrence F. Clark in the case of Commonwealth v Schildt ruled that the current calibration methods for Pennsylvania breath testing machines leave the devices inadequate to measure samples outside of the range of 0.05% to 0.15%. The ruling opens the door for thousands of the Highest BAC (over 0.16%) cases to be reviewed.
In his ruling, Judge Clark writes, “the utilization of any instrument reading above or below that range cannot, as a matter of science and therefore the law, satisfy the Commonwealth’s burden of proof beyond a reasonable doubt on an essential element of a charged offense for an alleged violation of 75 Pa.C.S.A. §3802(c) of the Pennsylvania Motor Vehicle Code.” (View the complete ruling in Commonwealth v Schildt).
