The Tennessee Supreme Court has issued another opinion about expert testimony, this one concerning the ability of a family practice doctor to testify about a criminal defendant’s ability to form the required mental state to commit a crime. The Court ruled that the expert was qualified to give such an opinion and that it was error to exclude his testimony.
The case is State v. Ferrell, No. M2005-02552-SC-R11-CD (Tenn. 1/29/09). Read about last opinion of the Court on expert testimony here.
