Vangelder was recently affirmed by the California Supreme Court when he prevented a jury from listening to expert testimony on the general unreliability of scientific techniques underlying breathalyzer tests. If appealed to the U.S. Supreme Court, this decision could limit or exclude expert testimony on the scientific unreliability and inaccuracy of breathalyzer tests across all jurisdictions, abolishing what can be a strong defense against an OUI charge.<\/p>\n<p>In the matter of <a href=\"http:\/\/www.courts.ca.gov\/opinions\/documents\/S195423.PDF\">People v. Vangelder<\/a>, a state officer clocked Vangelder driving late into the night on a speeding on a state highway. After following Vangelder for a few miles without observing any signs of intoxication, the officer pulled Vangelder over to the shoulder of the road. Vangelder was fully compliant with all of the officer&#8217;s instructions. After being questioned, Vangelder told the officer that he had three glasses of wine at dinner, and that he was just goofing around on the road. <\/p>\n<p>Vangelder passed all field sobriety tests, and then submitted to preliminary breathalyzer tests. The results came in at 0.095 and 0.086. After Vangelder was arrested (the state limit is 0.08) and transported to the station, he submitted to two more breathalyzer exams which returned a reading of 0.08. Vangelder was charged with two misdemeanors &#8211; <a href=\"http:\/\/www.dmv.ca.gov\/pubs\/vctop\/d11\/vc23152.htm\">a generic OUI offense, and the more specific offense of driving with a BAC reading above 0.08 percent<\/a> &#8211; despite the inconsistencies in the BAC readings. <\/p>\n<div class=\"read_more_link\"><a href=\"https:\/\/www.delsignoredefense.com\/blog\/california-high-court-bars-exp\/\"  title=\"Continue Reading California Supreme Court bars expert testimony on the scientific unreliability of breathalyzer tests\" class=\"more-link\">Continue Reading \u203a<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>A California trial judge presiding over the OUI trial of People v.
