2021 Oregon Revised Statutes|Volume : 04 - Criminal Procedure, Crimes|Chapter 132 - Grand Jury, Indictments and Other Accusatory Instruments|Section 132.540 - Sufficiency of indictment; previous convictions; use of statutory language; when name of victim not required.

(1) The indictment is sufficient if it can be understood therefrom that: (a) The defendant is named, or if the name of the defendant cannot be discovered, that the defendant is described by a fictitious name, with the statement that the real name of the defendant is to the jury unknown. (b) The crime was committed within the jurisdiction of the court, except where, as provided by law, the act, though done without the county in which the court is held, is triable therein. (c) The crime was committed at some time prior to the finding of the indictment and within the time limited by law for the commencement of an action therefor. (2) Except as provided in ORS 136.765 (1) and subsection (3) of this section, the indictment may not contain allegations that the defendant has previously been convicted of the violation of any statute that may subject the defendant to enhanced penalties. (3) The indictment must allege that the defendant has previously been convicted of an offense when the previous conviction constitutes a material element of the charged offense. (4) Words used in a statute to define a crime need not be strictly pursued in the indictment, but other words conveying the same meaning may be used. (5)(a) An indictment may include a pseudonym, initials or another signifier instead of the name of a victim if: (A) At least one of the crimes alleged to have been committed against the victim in the indictment is a sex crime as defined in ORS 163A.005; (B) A separate document containing the name of the victim and the corresponding pseudonym, initials or other signifier is filed with the clerk of the court at the same time as the indictment is filed; and (C) A copy of the document described in subparagraph (B) of this paragraph is provided to the defense attorney or, if the defendant does not have a lawyer, in accordance with paragraph (c) of this subsection, at the time of arraignment on the indictment. (b) The defense attorney may orally inform the defendant of the name of the victim contained in the document described in paragraph (a)(B) of this subsection but may not provide a copy of the document to the defendant. (c) If a defendant is not represented by a lawyer, the district attorney shall provide a copy of the document described in paragraph (a)(B) of this subsection to the defendant. At the time of providing the document, the court shall enter an order prohibiting the defendant from copying the document or providing the document to any other person. (d) The document described in paragraph (a)(B) of this subsection is confidential with respect to any person who is not a party to the case. At any time during the proceeding the court may, upon a finding of good cause, order that the document is not confidential. Once the final judgment on the case is entered, the document is no longer confidential. [Amended by 1957 c.657 §1; 1973 c.836 §57; 2009 c.180 §1; 2019 c.338 §1]
