A town judge in the Buffalo suburb of Hamburg dismissed the drunken-driving charges this month after Marusak presented a doctor's research showing the woman had the previously undiagnosed condition in which high levels of yeast in her intestines fermented high-carbohydrate foods into alcohol.
The rare condition, also known as gut fermentation syndrome, was first documented in the 1970s in Japan, and both medical and legal experts in the U.S. say it is being raised more frequently in drunken-driving cases as it is becomes more known.
"At first glance, it seems like a get-out-of-jail-free card," said Jonathan Turley, a law professor at George Washington University.
During the long wait for an appointment, Marusak arranged to have two nurses and a physician's assistant monitor his client for a day to document she drank no alcohol, and to take several blood samples for testing.
The Buffalo News described her as a 35-year-old school teacher, and quoted the arresting officer as saying she had bloodshot eyes, slurred speech, and failed several field sobriety tests.
