Physiologically, it could cause an aberrant reading, but there would be evidence of the problem at the time that you took the chemical breath test, and modern devices will shut down and state that there is vomitus in the tube or machine. Discuss this with your attorney.
If you found this "helpful" or "best answer," please click it with my appreciation. My response is for educational purposes and does not constitute legal advice nor creates an attorney client relationship which requires all the details and a personal conference.
You need an expert to analyze this and explain it to a jury. If you get a very good criminal defense attorney familiar with DWI cases, they usually have an array of expert to work with. This isn't the time for DIY defense.
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
Attorney Solis is 100% correct. Even in "run of the mill" DWI cases with no additional factors, defending yourself without the aid of a qualified DWI defense attorney is a poor idea. Doing so when you hope to raise a specialized defense of a medical nature is even less advisable.
You need to retain an attorney who will discuss this potential defense with you, and who can interact with your physician to review what, if any, defense may lie in your medical records. I suggest you do so as quickly as you can.
