Attorneys for a Palm Beach County millionaire convicted of DUI manslaughter will go before the Florida Supreme Court this week to challenge state rules for testing blood-alcohol levels in drunken-driving cases.

The hearing Wednesday is part of years of legal wrangling in the high-profile case of John Goodman, who was convicted and sentenced to 16 years in prison in the 2010 traffic death of Scott Patrick Wilson.

Justices will hear arguments about whether the Florida Department of Law Enforcement has adequate rules to ensure that blood-alcohol tests conducted in DUI cases provide accurate results. The arguments will focus, at least in part, on allegations that the state doesn't have adequate safeguards to prevent drawn blood from clotting — potentially resulting in artificially high measurements of blood-alcohol levels — and doesn't require proper screening of samples.
