American Bar Association Standards of Criminal Justice Relating to Prosecution Function
PART I -GENERAL STANDARDS
Standard 3-1.1 The Function of the Standards
These standards are intended to be used as a guide to professional conduct and performance. They are not intended to be used as criteria for the judicial evaluation of alleged misconduct of the prosecutor to determine the validity of a conviction. They may or may not be relevant in such judicial evaluation, depending upon all the circumstances.
Standard 3-1.2 The Function of the Prosecutor
(a) The office of prosecutor is charged with responsibility for prosecutions in its jurisdiction.
(b) The prosecutor is an administrator of justice, an advocate, and an officer of the court; the prosecutor must exercise sound discretion in the performance of his or her functions.
(c) The duty of the prosecutor is to seek justice, not merely to convict.
(d) It is an important function of the prosecutor to seek to reform and improve the administration of criminal justice. When inadequacies or injustices in the substantive or procedural law come to the prosecutor's attention, he or she should stimulate efforts for remedial action.
(e) It is the duty of the prosecutor to know and be guided by the standards of professional conduct as defined by applicable professional traditions, ethical codes, and law in the prosecutor's jurisdiction. The prosecutor should make use of the guidance afforded by an advisory council of the kind described in standard 4-1.5.
Standard 3-1.3 Conflicts of Interest
(a) A prosecutor should avoid a conflict of interest with respect to his or her official duties.
(b) A prosecutor should not represent a defendant in criminal proceedings in a jurisdiction where he or she is also employed as a prosecutor.
(c) A prosecutor should not, except as law may otherwise expressly permit, participate in a matter in which he or she participated personally and substantially while in private practice or nongovernmental employment unless under applicable law no one is, or by lawful delegation may be, authorized to act in the prosecutor's stead in the matter.
(d) A prosecutor who has formerly represented a client in a matter in private practice should not thereafter use information obtained from that representation to the disadvantage of the former client unless the rules of attorney-client confidentiality do not apply or the information has become generally known.
(e) A prosecutor should not, except as law may otherwise expressly permit, negotiate for private employment with any person who is involved as an accused or as an attorney or agent for an accused in a matter in which the prosecutor is participating personally and substantially.
(f) A prosecutor should not permit his or her professional judgment or obligations to be affected by his or her own political, financial, business, property, or personal interests.
(g) A prosecutor who is related to another lawyer as parent, child, sibling, or spouse should not participate in the prosecution of a person who the prosecutor knows is represented by the other lawyer. Nor should a prosecutor who has a significant personal or financial relationship with another lawyer participate in the prosecution of a person who the prosecutor knows is represented by the other lawyer, unless the prosecutor's supervisor, if any, is informed and approves or unless there is no other prosecutor authorized to act in the prosecutor's stead.
(h) A prosecutor should not recommend the services of particular defense counsel to accused persons or witnesses unless requested by the accused person or witness to make such a recommendation, and should not make a referral that is likely to create a conflict of interest. Nor should a prosecutor comment upon the reputation or abilities of defense counsel to an accused person or witness who is seeking or may seek such counsel's services unless requested by such person.
Standard 3-1.4 Public Statements
(a) A prosecutor should not make or authorize the making of an extrajudicial statement that a reasonable person would expect to be disseminated by means of public communication if the prosecutor knows or reasonably should know that it will have a substantial likelihood of prejudicing a criminal proceeding.

Standard 3-1.5 Duty to Respond to Misconduct
(a) Where a prosecutor knows that another person associated with the prosecutor's office is engaged in action, intends to act or refuses to act in a manner that is a violation of a legal obligation to the prosecutor's office or a violation of law, the prosecutor should follow the policies of the prosecutor's office concerning such matters. If such policies are unavailing or do not exist, the prosecutor should ask the person to reconsider the action or inaction which is at issue if such a request is aptly timed to prevent such misconduct and is otherwise feasible. If such a request for reconsideration is unavailing, inapt or otherwise not feasible or if the seriousness of the matter so requires, the prosecutor should refer the matter to higher authority in the prosecutor's office, including, if warranted by the seriousness of the matter, referral to the chief prosecutor.
(b) If, despite the prosecutor's efforts in accordance with section
(a), the chief prosecutor insists upon action, or a refusal to act, that is clearly a violation of law, the prosecutor may take further remedial action, including revealing the information necessary to remedy this violation to other appropriate government officials not in the prosecutor's office.

Wherever possible, a unit of prosecution should be designed on the basis of population, caseload, and other relevant factors sufficient to warrant at least one full-time prosecutor and the supporting staff necessary to effective prosecution.
(b) In some states, conditions such as geographical area and population may make it appropriate to create a statewide system of prosecution in which the state attorney general is the chief prosecutor and the local prosecutors are deputies.

(e) A prosecutor should strive to develop good working relationships with defense counsel in order to facilitate the resolution of ethical problems. In particular, a prosecutor should assure defense counsel that if counsel finds it necessary to deliver physical items which may be relevant to a pending case or investigation to the prosecutor the prosecutor will not offer the fact of such delivery by defense counsel as evidence before a jury for purposes of establishing defense counsel's client's culpability.

Standard 3-3.2 Relations With Victims and Prospective Witnesses
(a) A prosecutor should not compensate a witness, other than an expert, for giving testimony, but it is not improper to reimburse an ordinary witness for the reasonable expenses of attendance upon court, attendance for depositions pursuant to statute or court rule, or attendance for pretrial interviews. Payments to a witness may be for transportation and loss of income, provided there is no attempt to conceal the fact of reimbursement.
(b) A prosecutor should advise a witness who is to be interviewed of his or her rights against self-incrimination and the right to counsel whenever the law so requires.
