This client came as a referral from a Provincial Court Judge. The Judge’s nephew had been stopped for speeding by a Sheriff on Hwy 2 by Airdrie. In dealing with the client, the Sheriff suspected that D. was impaired and requested that an RCMP member. Once the officer attended he spoke with the client who confirmed he had consumed 5 beers. A roadside breath sample was requested and an E31 message. This error indicates that a sample is over range. After obtaining this reading, the office elected to arrest the client and obtain breath samples at the RCMP detachment. Both samples were more than double the legal limit. In reliance on the Alcosensor FST Operating Manual, Mr. Wyman was able to argue that the officer should not have relied upon the error message and ought to have conducted a re-test to allow for the dissipation of mouth alcohol. The argument was a convincing one and Mr. S was spared a criminal conviction.
