We see forensic evidence being used in criminal cases such as murder, but what about DUI cases? Torrance Attorney Matthew Ruff did just that in a recent case involving a client who worked for a major utility company, had a a commercial license that was in jeopardy of being lost if he lost the case. Here is a summary of the facts:

The client was stopped on the 605 freeway by CHP for speeding and weaving. He was asked if he had been drinking and admitted to consuming wine earlier in the evening. He was given various FST exams and, according to the officer, failed those tests. A breath test was administered in the field which displayed a .11 and .12, he was promptly arrested.

While at the station the client submitted to another chemical test which was consistent with the first BAC tests out in the field. He was booked, his license was confiscated and he spent the night in jail. Upon release he was issued a Court date and a DMV document that explained he was facing a mandatory 4 month suspension of his non-commercial driving privilege and a 1 year suspension of his commercial license which he needed for his job.

The client called around looking for a lawyer that could help. He then spoke to a co-worker who had a similar dilemma years earlier and was represented by Matthew who agreed to take his case.

During the investigation of the facts if the case, Matthew concluded that the client was a classic “rising blood alcohol” as it related to his true BAC at the time of driving. Here’s why: The client drank wine earlier in the evening, his last drink was within an hour of his stop and arrest. He drank nothing prior to that in the day. His alcohol consumption fit a pattern that put him in the absorptive phase of impairment. This meant that although his breath results were high at the time of his arrest and later at the station, at the time of driving he was much lower.

You see, under California law all that is important in DUI cases is what the driver’s blood alcohol level was when he was behind the wheel moving. Although there is a presumption that the motorist was the same BAC while driving as he was at the time of the test, that presumption is rebuttable, meaning that if the lawyer presents affirmative evidence that the accused was rising, that is admissible to bring him below a .08. In this case, the evidence was brought in via a forensic toxicologist who opined that the client was actually a .06 when he was stopped and lated climbed to the levels depicted by the breath machine.

As a result of this forensic testimony, the DMV set aside the license suspension and took no action against the client’s commercial driving privilege.
