LAS VEGAS -- More than 11 years have passed since a minivan driven by Jessica Williams drifted into a work crew of teenagers picking up trash along Interstate 15.
The accident killed six of the teens and landed Williams in prison.
Since her sentencing, Williams' attorneys have waged a lengthy legal battle to have her conviction overturned.
Williams' case is among the most controversial in recent memory. In large part due to the legal issues related to her conviction for driving with a prohibited substance in her blood.
Williams had marijuana metabolites in her system at the time of the accident.
Chief among the issues now before the court are two contradictory state laws that defined "prohibited substances" at the time of Williams' trial.
One listed marijuana metabolites and one that didn't.
Before Judge Michelle Leavitt Wednesday morning, Williams' attorney argued those contradictory statutes failed to provide Williams proper notice as to whether it was legal to drive under the influence of marijuana metabolites.
Essentially, attorney Michael Pescetta argued that the lack of agreement in the law violates Williams' due process rights.
Prosecutor Bruce Nelson disagreed, arguing the state supreme court has already decided the issue and not in Williams' favor.
"She's on notice that she can't smoke marijuana and drive a car," prosecutor Bruce Nelson said. "That's what she chose to do. That resulted in the deaths of six children. That's what she was fairly convicted of and that's what should be affirmed by this court, your honor."
The judge plans to issue a written order at a later date.
Should Williams win, Nelson told the I-Team the state will appeal.
Among those in attendance today were members of Williams' family.
They told the I-Team that after 11 years in prison she has more than paid for her crime.
Williams has long maintained that she was not impaired at the time of the accident; rather, she fell asleep at the wheel after a long night.
