It isn't legal for a lawyer to lie.
In fact, unlike most people, a lawyer can be disbarred and lose his entire livelihood if caught lying. A lawyer cannot legally say anything at trial that he knows to be untrue, nor present any evidence that he knows to be perjured.
Remember, pleading 'not guilty' is NOT the same thing as saying "I didn't do it." It is the lawyers job to make the government PROVE that you did what they claim you did.
Michigan DUI Law
Of the 1,155 traffic fatalities on Michigan highways in 2004, 329 involved a driver with a blood alcohol concentration of .08 or greater, which is over the legal limit. 201 of those deaths involved a driver who had a concentration of more than twice the legal limit.
Michigan makes it illegal to operate a motor vehicle with a blood alcohol concentration of greater than .08. Additionally, it is illegal to operate a motor vehicle while you are “visibly impaired” by alcohol or other drugs.
First Conviction: The first conviction is a misdemeanor. The court has discretion to apply any or all of the following penalties: up to 360 hours of community service, up to 93 days in jail, and a fine of $100 - $500.
Second Conviction in 7 Years: The second conviction is also a misdemeanor. This time the court will apply a fine of $200 - $1,000 and either (1) a jail term of 5 days – 1 year (48 hours of which must be served consecutively) or (2) 30 – 90 days of community service or (3) some combination of the two.
Third Conviction in 10 Years: This conviction is a felony. The court will fine you $500 - $5,000. Additionally the court will either sentence you to (1) 1 – 5 years in prison or (2) 30 days – 1 year in jail, plus 60 – 180 days of community service. Finally, on the third conviction, Michigan may take possession of your car and sell it at auction.
** in some states, if you are above the legal limit, with the key in the ignition, it is still considered a DUI regardless if the vehicle is actually turned on**
