Sections 15-12-26, 15-12-27, and 15-12-28 shall not be construed to preclude judges from appointing counsel for indigent defendants, or from assigning representation of an indigent defendant to other contract counsel where there is a conflict of interest involving the contract counsel, or if the contract counsel is unable to provide prompt and adequate representation, and the indigent defense systems chosen do not provide any other alternative. Sections 15-12-26, 15-12-27, and 15-12-28 shall not be construed to supersede any provision of the Alabama Rules of Criminal Procedure or any other provision of law relating to public defenders.
