Yes but if you have medical condition that didn't allow you to submit necessary volume for required period of time it may help as a defense in your case.
It can be asserted to be a refusal. The police can convict based on the SFST tests at the scene without a breath test. If you were charged with DWI and Refusal that would be a strong indication.
Generally it will not help you as some police departments don't even have a video in the station and some don't even have in car videos. I suggest you speak with an experienced DWI Lawyer to see what if any better defense you have in your case. Most of us DWI lawyers offer a free in office consultation, I suggest you set one up ASAP.
