In my experience, it is unlikely that the matter will be dismissed unless of course there is a significant proof problem such as the prosecution's inability to establish operation. Most counties that I have practiced in are hesitant to even plea bargain refusals, though that's not always the case. Assuming the matter is not dismissed or resolved after trial with a favorable verdict, he should probably be forthright and honest with the disciplinary committee when applying for admission. After all, as an attorney/soon to be attorney, you are required to conduct yourself in a manner befitting an attorney which includes being honest. While I am no expert on the character and fitness portion of admission to the bar, I'm wagering a guess that others in a similarly situated position have been granted admission to the bar notwithstanding their convictions. I suspect that the interviewer will not only consider the DWI but your friend's entire history and background. I'm not so sure that a DWI conviction, assuming it ends that way, would be grounds, by itself, to deny admission. My advice is to contact your local bar association and ask if you may speak with one of the attorneys who practices in the area of Ethics. That way, you can get an opinion from someone who focuses on cases involving misconduct. Lastly, you may even want to ask your local bar if they have archived ethics opinions on the subject. That may shed some light. I hope this answer helps and good luck!
