The law in Tennessee aimed at countering driving under the influence can result in harsh penalties. That should come as no great shock to readers. Multiple convictions for DUI tend to compound the penalties.
One should never underestimate the importance of thoroughness in the preparation of the defense of a criminal case. It doesn't matter if the accusation is a relatively minor first-offense for drunk driving or if a history of previous convictions has elevated the issue to a felony DUI charge. Penalties under Tennessee law are strict and mounting a defense that delivers the best possible outcome requires meticulous attention to detail.
The nuances of the law are not for the faint of heart. Those who practice the law go to great lengths to gain the knowledge and experience necessary to be able to understand the text of the laws and then present arguments that allow courts and juries to consider new ways of interpreting what that text means.
