According to BELLEVUE v. MOCIULSKI, 51 Wn. App. 855, 756 P.2d 1320 (1987):
Quoting Bellevue v. Mociulski
Before the machine is deemed reliable, the witness testing the machines or monitoring the testing must first show his/her qualifications to make and/or evaluate the tests. The witness must first qualify as an expert via knowledge, skill, experience, training, or education. ER 702. After the witness has qualified as an expert, he/she must show that the machines passed the requisite tests and checks. Only then can the speed measuring devices be deemed reliable.
According to Mociulski, the "expert witness" MUST be the one who performs or supervises the testing. However, in the radar certification you have, two different SMD experts -- Steen Nicholson and Anthony Hillock -- both present their qualifications, showing their training and experience. Both seem to be quite qualified.
However, BOTH certificates then state: "On the date indicated in Exhibit "A" which follows, each SMD was tested under the direction of a certified SMD expert". That means that your device was NOT NECESSARILY TESTED (or supervised) BY THE PERSON WHO SIGNED THE AFFIDAVIT! In fact, the "Certifying Official" for your device, designated in the CO column, has the initials "GWH". Those initials don't seem to correspond to EITHER SMD expert's initials.
Therefore, the person who did the testing was NOT the person who signed the form as REQUIRED in Molciulski and ER 602 (no personal knowledge).
