Sawyer v. Commonwealth - Subject Matter: Burden of Proof
It is the prosecutor's responsibility to prove all elements of a crime beyond a reasonable doubt. Nevertheless, when the prosecutor enters a driving record to prove a prior conviction in DUI cases and the elements required in order to make that prior conviction a valid prerequisite offense are missing the prosecution does not have to prove the validity of this element. The burden shifts to the Defendant who must prove that this element of the crime is invalid in order to prove his innocence.
