I had a Co-worker refuse a Breathalizer after an car accident, approx 5 years ago. He lost his drivers license for 6 months. He had to take a Taxi for every flight, but I don't recall any other flying issues arrising from it.
I used AOPA legal services a few years back for an unrelated issue. I think I paid the $20-30 and they did give me a to an aviation Lawyer who did give me a free first meeting and some good advise.
