                                ABSTRACT

    The  advent  of modern  breath  alcohol testing devices has led to a
fundamental shift in the methods used to detect and prosecute impaired drivers.
And  although these modern devices present a convenient and practical tool for
use in the criminal justice system, this convenience often comes with the price of
potentially inconsistent and frequently unreliable legal application. When a
detailed examination of the scientific principles animating breath alcohol testing
is undertaken, it is evident that there are significant analytical limitations
associated with current breath testing practices which have the potential to
preclude a fair and consistent adjudication for many defendants involved in the
legal system. This article seeks to address some of those limitations and
inconsistencies in the context of mandatory per se sentencing schemes for
alcohol-related offenders. Overall, this article contends that while breath
alcohol testing is an invaluable prosecutorial tool, the legal system has placed
too much credence in breath testing results without a necessary consideration of
the analytical variables associated with such results. This article argues that
because  of physiological and performance-related inconsistencies associated
with  modern  breath  testing methods, states should eliminate mandatory
minimum   sentencing enhancement schemes  that are premised exclusively on
threshold breath alcohol test results. Such results are certainly instrumental in
prosecuting  and sentencing DUI  offenders, but these mandatory minimum
sentencing schemes fail to consider both endogenous and exogenous test-related
idiosyncrasies and may  promote  enhanced  punishment  based on variables
unrelated to a relative diference in legal culpability. As an effective alternative
to these mandatory schemes, this article concludes that states should embrace
judicial sentencing discretion that can adequately consider the unique analytical
circumstances of each defendant's case.
