Chris.... Though it happens infrequently, and may be the result generalization , you are wrong on this one. While the right to appeal on a nolo contendre varies from state to state on restrictiveness, it is not wholly without appeal. it gets even more complicated when you begin throwing Alford pleas in the mix. What most don't understand is the primary reason for the no contest plea. Although it has become a popular way of accepting a plea bargain to a lessor charge, the actual intent on pleading no contest is that it can not be used as a conviction in civil proceedings.
this means that if you drive drunk and hit somebody, you can plead no contest to the criminal charge, but in the civil case, they can NOT imply or state that you were convicted of drunk driving. it is up to the prosecuting atty to prove that you were driving drunk, the criminal convection cannot be admitted.
