The ethical dilemmas in criminal justice begin even before pretrial. One significant ethical dilemma occurs when a defendant gives false material biographical information. In the even that the defendant is convicted and sentenced, this falsification could "change the defendant’s total offense level by five offense levels." The defense attorney then has the ethical dilemma resulting from the need to direct the defendant to correct the fictitious information given to investigators even if the attorney was not employed at that time.
defense counsel has an ethical obligation to take “remedial measures,” which typically means she must advise the defendant to correct the false statement, (Newton, Recurring Ethical Issues Related to Sentencing)
