Michigan DUI - Independent Blood Test
In Michigan, a defendant has the right to an independent blood test after the police breath test or even the police blood test. If you have any concerns about the integrity of the test, you should consider having your own test conducted.
Moreover, if the police deny your client’s reasonable request for the independent blood test, the jury will receive an instruction that the police violated the defendant’s statutory right to get an independent test.
The issue with the independent blood test is you don't get to decide if it becomes evidence - for better or worse, higher or lower result it will be part of the evidence. Many defenses revolve around questioning the accuracy of the breath test, and if you have a blood test, that YOU ASKED for confirm those results, you don't have much room to argue a defense based on a faulty machine result.
