I agree with the other attorney. Clearly there is an issue where the case is not showing as resolved. This needs to be taken care of by the attorney that handled the DUI, otherwise you will continue to have to deal with the possible extradition every time you are stopped by a police officer.
Yes you should put it in writing that you want an in-person meeting with your attorney. Attorney has a responsibility to communicate with their clients. You need to document your difficulty in dealing with the attorney.
I would concur with Mr. Sweat. I realize you didn't see the automobile and thought that traffic was clear, but if it was safe to make a left hand turn then the accident would not have happened. If however the car belonged to david cooperfield and he made it appear, you have a legit defense.
The question you are posing is extremely difficult to answer with the limited facts provided. Yes a defamation lawsuit can always be filed, but if it is warranted is dependant on the facts behind the case. You should consult a local attorney in regards to this issue. Keep in mind, the person who is being lied about is the only one with the ability to sue.
