In this criminal case, the issue is the facial constitutional validity of ORS 166.015, Oregon’s “riot” statute, which provides:
“(1) A person commits the crime of riot if while participating with five or more other persons the person engages in tumultuous and violent conduct and thereby intentionally or recklessly creates a grave risk of causing public alarm.
“(2) Riot is a Class C felony.”
We hold that the statute is not facially unconstitutional in any respect asserted by defendants.
BACKGROUND
In a single indictment, the state charged defendants jointly, under ORS 166.015, with one count of riot. Defendants demurred, asserting, inter alia, that: (1) ORS 166.015 violates Article I, section 8, of the Oregon Constitution, 1 because the statute restrains expression 2 and does not fall within a well-established historical exception to the Oregon constitutional guarantee of free speech; 3 (2) ORS 166.015 is unconstitutionally overbroad in that it criminalizes expression protected under Article I, section 8; 4 and (3) ORS *374 166.015 is unconstitutionally vague in violation of Article I, sections 20 and 21, of the Oregon Constitution, 5 and the Due Process Clause of the Fourteenth Amendment to the United States Constitution. 6
The trial court sustained the demurrer, concluding that ORS 166.015 is unconstitutionally overbroad in its reach. Because the trial court further concluded that the constitutional violation could not be avoided in a new accusatory instrument, the court dismissed the riot charge with prejudice. On the state’s appeal, the Court of Appeals reversed, holding that ORS 166.015 is not unconstitutional on its face.
State v. Chakerian,
1. Article I, Section 8, Challenge
Defendants argue first that, on its face, ORS 166.015 violates Article I, section 8, of the Oregon Constitution. In
State v. Robertson,
*375
If the statute is not directed to thе substance of an opinion or subject of communication, but rather is directed at a harm that the legislature is entitled to proscribe, then a further level of inquiry follows.
Id.
at 414-17.
See generally State v. Stoneman,
The first level of analysis may be dispensed with easily. As defined in ORS 166.015, the crime of riot has four elements: A pеrson commits the crime of riot if that person, (1) “while participating with five or more persons,” (2) “engages in tumultuous and violent conduct” 8 and (3) “thereby intentionally or recklessly” (4) “creates a grave risk of causing public alarm.”
ORS 166.015, by its terms, is not directed at speech at all, let alone at restraining the free expression of opinion or the right to speak freely on any subject. Rather, the statute is directed at a harm — the creation of a grave risk of public alarm. ORS 166.015 by its terms prоscribes only a certain type of conduct — conduct that is “violent and tumultuous.” The statute does not fit under level one of Robertson.
Turning to the second level of analysis, defendants argue that, even if ORS 166.015 is directed at a proscribable harm — creation of a grave risk of public alarm — the statute is overbroad, because it prohibits too much expression in order *376 to protect against that harm. The pivotal questions, as argued by defendants, are whether that part of ORS 166.015 that proscribes engaging in “tumultuous and violent conduct” forbids making “threats” in all instances, whether making “threats” constitutes protected expression and, if so, whether the court can interpret the statute narrowly to avoid possible overbreadth. 9 Of course, the statute does not itself use the word “threats” at all. Rather, we must consider whether, by proscribing “tumultuous and violent conduct,” the legislature intended to proscribe acts that could constitute protected expression under Article I, sеction 8, of the Oregon Constitution. If it did not, defendants’ argument fails.
Defendants’ argument that the answer to the foregoing question is “yes” relies on a statement in the Oregon Criminal Law Revision Commission’s commentary concerning ORS 166.015. 10 That commentary asserted that the phrase “tumultuous and violent conduct” means “terroristic mob behaviour involving ominous threats of personal injury and property damage.” Proposed Oregon Criminal Code § 218 (Commentary) at 212 (1970) (emphasis added). It is from that source that defendants attempt to draw the concept of “threats” into the discussion.
Defendants argue that a “threat” is a kind of expression and, therefore, that the type of conduct prohibited by ORS 166.015 — tumultuous and violent conduct — must be construed to be expressive in nature.
This court interprets statutory terms under the methodology set out in
PGE v. Bureau of Labor and Industries,
The text of ORS 166.015 prohibits persons from engaging in “tumultuous and violent conduct.” These are words of common usage, to which we typically ascribe their ordinary meaning. See id. at 611 (stating rule). “Tumultuous” is defined as:
“1: marked by tumult: full of commotion and uproar: riotous, stormy, boisterous * * * 2: tending or disposed to cause or incite a tumult * * * 3: marked by violent or overwhelming turbulence or upheaval.”
Webster’s Third New Int’l Dictionary, 2462 (unabridged 1993). The definition of “violent” is:
“1: characterized by extreme force * * *: marked by abnormally sudden physical activity and intensity * * * 2: furious or vehement to the point of being improper, unjust, or illegal * * * 3: extremely or intensely vivid or loud * * *: unusually intense * * *: unnaturally strong * * * 4: produced or effected by force : unnatural * * * 5: tending to distort or misrepresent * * * 6: extremely excited: emotionally aroused[.]”
Id. at 2554. Finally, “conduct” is defined as “behavior in a particular situation or relation or on a specified occasion.” Id. at 474.
The trial court concluded that the statute can be violated only by means of either speech or expressive conduct. It reached that conclusion by referring to the commentary of the Oregon Criminal Law Revision Commission and by reasoning that every statutory violation will involve communication of a “threat.” Defendant asserts that view here, contending that every threat is a communication of some sort.
As we discuss in greater detail below, we conclude that the trial court (and the Court of Appeals) erred in resorting to the commentary to discern the meaning of ORS 166.015. On the other hand, the Court of Appeals also held *378 that the trial court read the statute too narrowly in concluding that, in all cases, it proscribes making “threats.” We agree with that latter proposition. The common definitions of the statute’s key terms, quoted above, demonstrate that the statute, on its face, fоrbids forms of overt criminal behavior that are unattended by speech of any kind. Defendant makes no other argument that the statute is invalid on its face under Article I, section 8. Giving the statute a fair reading in the light of the common definitions of the terms of “tumultuous,” “violent,” and “conduct,” we conclude that the statute refers to physical activity that reasonably is perceived by others as threatening an imminent breach of the peace. 11 That is, the word “threat” may or may not be аmbiguous; the statutory text — which does not contain that word — is not.
From the text of the statute alone, it appears that the legislature, in enacting ORS 166.015, intended to proscribe only nonexpressive acts. However, in carrying out this first level of analysis under PGE, we also look to the context of ORS 166.025.
As an initial matter, we are confronted with the question whether the commentary is “context” or, rather, should be treated as legislative history. If it is context, we consider it in the initial step of our PGE analysis. If it is legislative history, we would turn to it only if the text and context of the statutory phrase were ambiguous.
ORS 166.015 was enacted as part of the Oregon Criminal Code of 1971, which was the culmination of a comprehensive effort to revise substantive Oregon criminal law.
*379
While drafting the code, the Criminal Law Revision Commission compiled an accompanying commentary. We consider that commentary to be part of the legislative history of the Code.
See, e.g., State v. Wille,
Context does include other related statutes.
PGE,
ORS 166.025, as enacted in 1971, provided, in part:
“(1) A person commits the crime of disorderly conduct if, with intent to cause public inconvenience, annoyance or alаrm, or recklessly creating a risk thereof, he:
“(a) Engages in fighting or in violent, tumultuous, or threatening behavior; or
“(b) Makes unreasonable noise; or
“(c) Uses abusive or obscene language, or makes an obscene gesture, in a public placet.]”
The significant difference between the disorderly conduct statute, ORS 166.025, and the riot statute, ORS 166.015, is that, in enacting ORS 166.025, the legislature intended to proscribe much more than just “fighting” and “violent, tumultuous or threatening behavior,” because paragraph (c) of ORS 166.025, as enacted in 1971, prohibitеd the use of “abusive or obscene language” and “obscene gesture [s].” The inclusion of those words in the text indicates that the legislature, in enacting ORS 166.025, intended to proscribe certain expressive conduct. Indeed, it was that specific part of that statute that this court declared “void as contrary to Art I, § 8 of the Oregon Constitution” in
State v. Spencer,
From our examination of the text and context of ORS 166.015, we find the statute’s meaning clear: The legislature did not intend to reach protected expression in prohibiting “tumultuous and violent conduct.” Accordingly, we need not proceed further with the PGE analysis.
Having determined that ORS 166.015 does not on its face forbid speech, it follows that the statute does not on its face violate rights protected by Article I, section 8. We turn to the question whether the statute nonetheless violates Article 1, section 8, on the alternative ground that it is vague.
2. Vagueness Claim
Defendаnts also challenge ORS 166.015 by asserting that it is unconstitutionally vague in violation of Article I, sections 20 and 21, of the Oregon Constitution. 12 Specifically, defendants argue that ORS 166.015 is vague to the extent that it prohibits conduct that “creates a grave risk of causing public alarm.”
Before reaching the merits, the state argues that this court should not consider defendants’ facial vagueness claim, if we conclude (as we have above) that ORS 166.015 is not directed at expression. The state’s argumеnt apparently is premised on a belief that, under Oregon law, a facial *381 vagueness challenge generally may not be brought by way of demurrer and that the sole exception to that rule arises when the challenged law is directed at speech. We first consider the validity of the state’s premise.
The state argues that this court has considered facial vagueness challenges only in a narrow range of cases in which the statute prohibited, by its terms, some form of сommunication.
13
We disagree with that argument. Our research has uncovered several cases that did not implicate free speech concerns, but in which the court nonetheless considered the merits of facial vagueness claims.
See, e.g., State v. Farrar,
This court’s case law never has purported to explain under what circumstances a facial vagueness claim may be brought. The only limitation on facial vagueness challenges to which this court has referred is that, to
succeed
on a facial claim, a party must show that a statute is unconstitutionally “ ‘vague in all of its possible applications.’ ”
Robertson,
From the foregoing, we conclude that defendants are entitled to have the court address their assertion that ORS 166.015 is unconstitutionally vague in all its possible applications, without regard to their individual conduct.
The parties agree that the vagueness issue before this court is limited to a challenge under the Oregon Constitution. Accordingly, we consider only Oregon constitutional law. The court in
Robertson
acknowledgеd that “the rule against vague penal laws has been rested on various constitutional premises.”
Defendants direct their facial vagueness challenge to the phrase, “grave risk of public alarm.” They argue that the
*383
phrase is unconstitutionally vague, because it lacks either a requirement that a person’s conduct
actually
cause “public alarm” or that the “public alarm” be
objectively reasonable.
Defendants argue that this court found similar deficiencies in a harassment statute in
State v. Blair,
We disagree. The statute at issue here, ORS 166.015, more closely resembles the amended harassment statute that this court upheld in
State v. Moyle,
Defendants in
Moyle
challenged that statute on the grounds that the terms “alarm,” “threat reasonably expected to cause alarm,” “serious physical injury,” and “felony’ were unconstitutionally vague. This court concluded that those terms “adequately inform[ed] potential defendants of the prohibited conduct, and they d[id] not delegate uncontrolled discretion to a judge or jury to punish or withhold punishment.”
Similarly, the phrase that defendants challenge in this case, “grave risk of public alarm,” when viewed in the *384 light of the requirement that the conduct causing the risk must be “tumultuous or violent,” adequately informs citizens of the prohibited conduct. The statute does not, it is true, specifically require that the “risk of public alarm” that is created be “reasonable,” as the statute did in Moyle. But we believe that that element is imported into the statute by the use of the adjective, “grave.” A risk is not “grave,” in our view, unless it would be perceived аs reasonably likely to occur. Thus, the statute does not delegate uncontrolled discretion to a judge or jury to punish or withhold punishment. Specifically, the challenged phrase is very like the one that this court sustained in Moyle.
We hold that ORS 166.015 is not unconstitutionally vague and does not violate Article I, sections 20 and 21, of the Oregon Constitution.
For the reasons expressed above, the trial court erred in sustaining defendants’ demurrer on the ground that ORS 166.015 is overbroad in violation of Article I, section 8, of the Oregon Constitution. Neither is the statute unconstitutional on any other ground asserted by defendant.
The decision of the Court of Appeals is affirmed. The judgments of the circuit court are reversed.
Notes
Article I, section 8, of the Oregon Constitution, provides:
“No law shall be passed restraining the free expression of opinion, or restricting the right to speak, write, or print freely on any subject whatever; but every person shall be responsible for the abuse of this right.”
As we have done in the past, we use the terms “speech” and “expression” interchangeably in this opinion to refer to the “free expression of opinion, or * * * the right to speak, write, or print freely on any subject whatever” provided in Article I, section 8, of the Oregon Constitution.
See, e.g., Huffman and Wright Logging Co. v. Wade,
In the trial court, defendants also demurred on the ground that ORS 166.015 violates the First and Fourteenth Amendments to the United States Constitution. Those federal free speech claims have not been advanced in this court.
The indictment was written in terms of the statute, without elaboration. We thus do not know what specific operative facts the state will show, if the case is remanded for trial. It follows that, because this case arises out of the trial court’s pretrial decision to sustain defendants’ demurrer, defendants are unable to assert at this time that the statute is unconstitutional as applied to them. Defendants also challenged the indictment in the trial court on the ground that it was not *374 definite and certain. ORS 135.630(6). The trial court asserted during the hearing оn defendants’ demurrer that it would deny the demurrer on that ground. However, the trial court’s order does not indicate that the demurrer was denied on that ground. Defendants have not raised on appeal whether the indictment violated ORS 135.630(6), and we do not address that question.
Article I, section 20, of the Oregon Constitution, provides:
“No law shall be passed granting to any citizen or class of citizens privileges, or immunities, which, upon the same terms, shall not equally belong to all citizens.”
Article I, section 21, provides, in part:
“No ex-post facto law * * * shall ever be passed * *
The Fourteеnth Amendment to the United States Constitution provides, in part:
“[N]or shall any State deprive any person of life, liberty, or property, without due process of law * *
Although their brief to this court argued the federal claim, defendants agreed at oral argument that no federal claims are before this court. Therefore, we do not address further defendants’vagueness claim under the federal constitution.
There is a third level of scrutiny that goes beyond a facial attack on a statute. If the statute targets a harm, but does not refer to expression at all, then the statute still is analyzed to determine whether it violates Article I, section 8, as
applied.
That is the third level of the
Robertson
analysis.
Miller,
It is clear under the statute that a person does not commit the crime of riot if he or she merely is part of a group and five other members of that group engage in tumultuous and violent conduct that intentionally or recklessly creates a grave risk of causing public alarm. Under the statute, the state must prove that the person charged actually “engage[d] in violent and tumultuous conduct.”
We note that "conduct” itself may be protected expression under Article I, section 8. Artistic conduct, such as dance, and political conduct, such as the carrying of protest signs, are just two of the more obvious forms of conduct that also are protected expression under Article I, seсtion 8. On the other hand, there also is conduct that is not protected expression under the Oregon Constitution. For instance, when a person physically assaults another, such conduct — even if it includes an underlying message or is accompanied by speech — is not protected expression.
The commentary was drafted by the Criminal Law Revision Commission along with its proposed revision of the Oregon Criminal Code. The commentary was available to the legislature throughout its deliberations on the proposed revision, which was adopted in 1971.
Of course, it always is possible that “tumultuous and violent conduct” might occur contemporaneously with some kind of expression in a particular instance. The idea of “tumult” as being boisterous talk is, for example, the one meant in what is perhaps the single most familiar use of the former word in the English language:
“The tumult and the shouting dies,
The Captains and the Kings depart * * *.”
Rudyard Kipling, “Recessional” (1897) in A Choice of Kipling’s Verse 139 (1941). Any doubt about that meaning is resolved in the light of the fact that Kipling’s poem was a sobering reflection on the transient nature of glory, published on the day following the enormous parade in London that celebrated the diamond jubilee of Queen Victoria. Barbara W. Tuchman, The Proud Tower, 55 (1965). But, read collectively, the statutory terms that we examine here are a reference to non- expressive acts.
Defendants argued in the Court of Appeals and to this court that the trial court “ruled” that the statute was not unconstitutionally vague and dismissed that claim. The state has not disputed that characterization, but the record does not appear to support such a conclusion. The trial court’s virtually identical orders with respect to each defendant stated only that the statute was unconstitutionally overbroad in its reach. The orders said nothing about vagueness.
Defendants rely on a portion of the transcript in which the trial court stated that it was bound by a previous Court of Appeals determination that the same statute was not unconstitutionally vague. Howevеr, it is the trial court’s order that determines what the trial court ruled, not what the trial judge said during the proceedings. In any case, after the colloquy cited by defendants, and after a lunch recess, the trial court modified its earlier conclusion and asserted that the statute might be both overbroad and vague.
Despite the fact that the trial court never signed an order that ruled on the issue, we still reach it, because it represents an alternative legal ground that was asserted to the trial court and оn which the trial court’s ruling in favor of defendants could be sustained.
The state lists three cases as examples:
State v. Moyle,
On occasion, the Oregon Court of Appeals has interpreted the limitations on facial challenges more broadly.
See, e.g., State v. Butterfield,
The statute at issue in Moyle, ORS 166.065(l)(d) (1983), provided:
“A person commits the crime of harassment if, with intent to harass, annoy or alarm another person, the actor:
«:£ * s-s ;-c He
“(d) Subjects another to alarm by conveying a telephonic or written threat to inflict serious physical injury on that person or to commit a felony involving the person or property of that person or any member of that person’s family, which threat reasonably would be expected to cause alarm[.]”
