Assitant district attorney Darrell Julian met with judicial commissioners and members of the county’s Policy and Personnel Committee on Monday night to explain steps judicial commissioners should take when requesting blood to be drawn in DUI cases. Judicial commissioners now have the authority to request a search warrant for blood tests to determine if a suspect has been driving under the influence.“Two years ago, it wasn’t possible to obtain a search warrant for DUI cases. Now all DUI cases require search warrants except where, just as a practical matter, it would be impossible to obtain one in any reasonable amount of time.
