Cassation overturns dui ruling: gastritis claims spark legal battle

A Pescara motorist has won a significant legal victory, with the Italian Court of Cassation overturning two previous convictions for driving under the influence. The case highlights a complex interplay between scientific evidence and judicial scrutiny, raising questions about the reliability of breathalyzer tests.

The initial verdict and the challenge

The driver, initially convicted in the first and second instances, had been stopped with a blood alcohol content (BAC) of 0.92 grams per liter – significantly exceeding the legal limit of 0.8. His defense centered on a pre-existing condition: chronic gastritis with gastroesophageal reflux, arguing that the condition could have skewed the results of the breathalyzer.

Gastritis and the breathalyzer: a question of interpretation

The core of the dispute revolved around whether the gastritis could have introduced volatile organic compounds into the driver’s mouth, mimicking the presence of alcohol and leading to a false positive reading. His expert witness presented compelling evidence suggesting this was a plausible scenario, demonstrating how gastritis can release molecules that instruments like breathalyzers misinterpret.

The cassation’s decision: a focus on due diligence

However, the Court of Cassation ruled that the lower courts had not adequately addressed the argument. They found that the previous rulings were predicated on a superficial assessment of the evidence, failing to fully consider the potential impact of the gastritis. The judges emphasized the need for a robust and detailed explanation of how the condition could have interfered with the test results – a critical element absent from the initial judgments.

A new beginning for the case

Consequently, the proceedings have been suspended, and a new trial is scheduled before the Court of Appeal in Perugia. This time, the court will be tasked with definitively determining the extent to which the gastritis influenced the breathalyzer reading, scrutinizing all available evidence and ensuring a thorough evaluation of the expert testimony. The case serves as a crucial reminder of the importance of meticulous investigation and accurate interpretation in legal proceedings, especially when medical conditions are invoked as mitigating factors.
