You'd have better luck asking the Public Defender's office in that courthouse. They're going to know about more motions in front of a particular judge than anyone.
No legal advice is given here. My responses to questions on Avvo are never intended as legal advice and must NOT be relied upon as if they were legal advice. I give legal advice ONLY in the course of a formal attorney-client relationship. Exchange of information through Avvo's Questions & Answers forum does not establish an attorney-client relationship with me. That relationship is established only by joint execution of a written agreement for legal services. I am only licensed in the States of California and New York and the District of Columbia
Very interesting question. Retroactive application is being litigated by members of the California DUI Lawyers Association (CDLA) with mixed results. CDLA's position is that it is retroactive since the requirement for a medically approved and necessary blood draw pursuant to the 4th Amendment has been in effect for over 40 years since Schmerber was decided by the US Supreme Court. If the question is whether the judge has ruled on the issue before, the best person to talk to your attorney or public defender.
