Substantial claim can be indicative only of oversight or ineptitude. You can make a motion for ineffective assistance of counsel during your trial if you feel that your lawyer is not performing their duties.A frequent ineffective assistance complaint is that the defense attorney did not obtain pretrial discovery. First, the defendant must demonstrate that counsel's performance was deficient. Significantly, prior to filing any claim of ineffective assistance, writ counsel must engage in a thorough and complete investigation. The Sixth Amendment's right to effective assistance attaches directly to the fidelity and competence of defense counsel's services. By the same logic, then, one could argue that the absence of an exclusionary remedy in the context of ineffective assistance of counsel claims. You can only claim ineffective assistance of counsel after a conviction. The 6th Amendment to the U.S. Constitution states that people accused of crimes have the right to a criminal defense attorney.
