¶1OPINION
¶2delivered the opinion of the Court
¶3Appellee was charged with the Class B misdemeanor offense of Disrupting [a] Meeting or Procession. Tex. Pen.Code § 42.05. Appellee filed a pre-trial motion to quash the complaint by attacking the constitutionality of § 42.05. The trial court granted appellee’s motion to quash the complaint. The State appealed. The Third Court of Appeals reversed the trial judge’s decision. State v. Markovich, 34 *276S.W.3d 21 (Tex.App.-Austin 2000). We granted appellee’s petition for discretionary review to decide whether the curtailment of others’ First Amendment rights is an element of § 42.05 and to determine if the statute is unconstitutionally vague on its face. We will affirm.
¶4I.
¶5Appellee was charged with disrupting a public meeting.
¶6The State appealed the trial court’s decision. On appeal the State argued that § 42.05 was not impermissibly vague. Markovich, 34 S.W.3d at 25.
¶7The Third Court of Appeals concluded that it did not understand this Court’s holding in Moreheadas making the curtailment of the exercise of others’ First Amendment rights as an element of the offense. Id.In addition, it held that § 42.05, as construed in Morehead, is sufficiently clear and understandable to satisfy the Fourteenth Amendment to the United States Constitution and Article I, Section 19 of the Texas Constitution. Id.
¶8II.
¶9We first turn to the issue of whether the curtailment of others’ First Amendment rights is an element of the offense of disrupting a public meeting. Appellee contends that the Third Court of Appeals erred by concluding that the phrase “thereby curtail others’ First Amendment rights” was not meant to be an element of the offense of disrupting a meeting, but simply as a phrase expressing this Court’s belief that its narrowing construction properly balances the First Amendment rights of all parties.
¶10In Moreheadthe appellant argued that § 42.05 was impermissibly overbroad in that it prohibited some constitutionally protected activity. 807 S.W.2d at 579. Although we concluded that the statute was overbroad, we held that it was susceptible to a narrowing construction that would be consistent with its language and apparent purpose. We explained:
Given the competing First Amendment freedoms at stake, § 42.05 can be rendered constitutional if it is construed to criminalize only physical acts or verbal utterances that substantially impair the ordinary conduct of lawful meetings, and thereby curtail the exercise of others’ First Amendment rights.
¶11Id. at 581 (emphasis in original).
¶12Appellee argues that because “More-head repeatedly stresses the importance of the free-speech-curtailment element” it is apparent that we intended it to be an added element to § 42.05. In Moreheadwe explained that although the State has a duty to ensure that an individual’s unruly assertion of his right of free expression does not imperil another citizen’s First Amendment freedoms, it could not forbid expressive conduct that is merely “provocative and challenging.” Morehead, 807 S.W.2d at 580. Therefore, with regard to § 42.05, we concluded that the best way to ensure that the rights of all individuals are protected is to determine whether the actor’s behavior substantially impaired the conduct of the meeting before his or her actions could be criminalized. Id. If an actor substantially interferes with a meeting, then it necessarily follows that others’ constitutionally protected rights have been infringed upon. This concept was added as one of further explanation. We did not intend that it add anything in the way of a substantive requirement.
¶13Moreover, it is apparent from the cases in which we have discussed the narrowing construction that was applied in Moreheadthat we have never considered curtailment of others’ First Amendment rights to be an element of § 42.05. In Long v. State, *278931 S.W.2d 285 (Tex.Crim.App.1996), this Court was asked to determine the constitutionality of the stalking statute. We turned to Moreheadas an example of this Court’s use of a narrowing construction “that increased the intensity of the conduct under scrutiny.” Id. at 296. We explained, “In Moreheadthis Court construed the words ‘obstruct’ and ‘interferes’ as applying only to conduct which substantially impaired the ordinary conduct of lawful meetings.” Id.We did not consider the curtailment of others’ First Amendment rights to be part of the narrowing construction.
¶14We also referred to Morehead’s narrowing construction in Olvera v. State, 806 5.W.2d 546 (Tex.Crim.App.1991). In Olv-era we determined the constitutionality of a picketing statute. As in Long, we used § 42.05 as an example of a statute that was readily subject to a narrowing construction:
In Morehead, we recently applied a narrowing construction to Tex. Penal Code Ann. § 42.05.... We noted that the broad language of § 42.05 encompasses “the full range of possible disturbances, from the most minor to the most significant,” but concluded that § 42.05 could pass a facial overbreadth challenge by construing it to criminalize only physical acts or verbal utterances that substantially impair the ordinary conduct of lawful meetings and thereby curtail the exercise of others’ First Amendment rights.
¶15Id. at 552 (citations omitted). Appellee considers the inclusion of the curtailment phrase in our discussion as proof that the curtailment of others’ First Amendment rights is an element of § 42.05. What ap-pellee fails to acknowledge is that in our discussion of Moreheadwe also explained that the narrowing construction concerned the amount of interference to a public meeting. See id. at 552 (emphasis added). We did not, however, indicate that we considered the narrowing construction to include the type of impact that such interference had on others’ rights.
¶16For the reasons discussed, the Court of Appeals did not err in concluding that the curtailment of others’ First Amendment rights was not intended to be included as a part of the narrowing construction expounded in Morehead. Appel-lee’s first ground for review is overruled.
¶17III.
¶18Appellee also claims that § 42.05 is unconstitutionally vague on its face.
¶19A statute will be declared unconstitutionally vague if “its prohibitions are not clearly defined.” Grayned v. City of Rockford, 408 U.S. 104, 108, 92 S.Ct. 2294, 33 L.Ed.2d 222 (1972). The statute must provide people of ordinary intelligence a reasonable opportunity to understand what conduct it prohibits. Id. at 108, 92 S.Ct. 2294; Long, 931 S.W.2d at 287. Moreover, the statute must provide explicit guidelines for those who enforce them. Grayned, 408 U.S. at 108, 92 S.Ct. 2294; Long, 931 S.W.2d at 287. Finally, where First Amendment freedoms are involved, the law must be sufficiently definite in order to avoid chilling expression. Grayned, 408 U.S. at 108, 92 S.Ct. 2294; Long, 931 S.W.2d at 287.
¶20Appellee argues that § 42.05 is im-permissibly vague because it fails to provide determinative enforcement guidelines to police. Relying on Kolender v. Lawson, appellee asserts that, “Proper enforcement of the statute would require officers to know and apply delicate issues of First Amendment jurisprudence before making an arrest by judging when the normally protected form of expression of heckling loses its protected character because it is suppressing the First Amendment right of others.” He also argues that the statute is vague because it requires individuals to “guess as to whether their contemplated conduct is prohibited by caselaw because it might curtail others’ free speech rights.”
¶21Appellee’s facial vagueness claim fails for several reasons. First, as we have just explained, the curtailment of others’ rights is not an element of § 42.05. As such, the statute does not require police officers or citizens to “know and apply delicate issues of First Amendment jurisprudence.” Section 42.05 simply prohibits individuals from intentionally engaging in behavior that has the effect of substantially disrupting or preventing the ordinary conduct of a meeting. Section 42.05 reaches only the disorderly physical or verbal conduct of individuals who are acting with the specific intent to prevent or disrupt a meeting. A person of ordinary intelligence knows the type of conduct that is likely to cause an impairment to the ordinary conduct of a meeting.
¶22The statute likewise provides law enforcement with determinative guidelines. Contrary to appellee’s contention, the statute in the present case is distinguishable from that which was held by the U.S. Supreme Court to be unconstitutional on vagueness grounds in Kolender. Kolender involved a California disorderly conduct statute that required a person to “identify” and “account for his presence when requested by an officer to do so.” 461 U.S. at 354, 103 S.Ct. 1855. The Court found the statute to be impermissibly vague:
It is clear that the full discretion accorded to the police to determine whether the suspect has provided a “credible and rehable” identification necessarily “[entrusts] lawmaking ‘to the moment-to-moment judgment of the policeman on his beat’ ” .... [The statute] “furnishes a convenient tool for ‘harsh and discriminatory enforcement by local prosecuting officials, against particular groups deemed to merit their displeasure,’ ” and “confers on police a virtually unre*280strained power to arrest and charge persons with a violation”.... Although the initial detention is justified, the State fails to establish standards by which the officers may determine whether the suspect has complied with the subsequent identification requirement.
¶23Id. at 360-61, 103 S.Ct. 1855 (citations omitted). Under § 42.05 police officers are not given the same discretion. As the Third Court of Appeals -correctly asserted, “Whether a person’s conduct substantially impairs the ordinary conduct of a meeting is an objective standard that does not acquire its meaning from a particular officer’s determination of what constitutes a ‘substantial’ impairment.” Markovich, 34 S.W.3d at 26. Although an officer must initially make a determination as to whether the statute has been violated before he makes an- arrest, the officer’s assessment of the defendant’s conduct is not the defining element of the offense. Id.
¶24Because § 42.05 “communicates its reach in words of common understanding,” Boos v. Barry, 485 U.S. 312, 332, 108 S.Ct. 1157, 99 L.Ed.2d 333 (1988), it provides guidelines for law enforcement and fair notice to citizens as to the type of conduct that is proscribed. Accordingly, we hold that § 42.05 is not unconstitutionally vague on its face. The judgment of the Third Court óf Appeals is affirmed.
¶25. Since this petition for discretionary review involves a pre-trial motion, no record has been developed regarding the specific facts of appellee’s case. However, at the pre-trial hearing appellee’s attorney asked the trial judge to take judicial notice of the probable cause affidavit The affidavit provides in pertinent part: "On or about 11-14-98 at about 11:00 A.M. while providing security at a speech by President George Bush, I Cpl. Brian Baster fIX DPS) observed Thomas Marko-vich stand up and shout over the voice of President Bush 'bull shit.’ Markovich then began shouting other protests, thereby causing the speaker to stop. The meeting was disrupted by Markovich. All events occurred in the house gallery of the Texas State Capitol in Austin, Travis County, TX.”
¶26. The First Amendment was made applicable to the States by the Due Process clause of the Fourteenth Amendment. Gitlow v. New York, 268 U.S. 652, 45 S.Ct. 625 (1925).
¶27. Section 42.05 provides in relevant part: "A person commits an offense if, with intent to prevent or disrupt a lawful meeting, procession, or gathering, he obstructs or interferes with the meeting, procession, or gathering by physical action or verbal utterance.” In Morehead, 807 S.W.2d at 581, we held that § 42.05 can be rendered constitutional only if it is construed to criminalize physical acts or verbal utterances that "substantially impair the ordinary conduct of lawful meetings .... ” (emphasis in original).
¶28. The amended information provides in pertinent part that: "Thomas Markovich, the Defendant, on or about the 14th day of November A.D. 1998, with the intent to prevent and disrupt a lawful meeting, to wit: A speech given by former President George Bush, did then and there obstruct and interfere with said meeting by physical action and verbal utterance, to wit: the Defendant stood up and shouted, causing former President Bush to stop speaking, and the Defendant’s physical acts and verbal utterances substantially impaired the ordinary conduct of the said lawful meeting.”
¶29. Although the trial court did not expressly set aside the information on vagueness grounds, the Third Court of Appeals nevertheless addressed the merits of the State's vagueness claim since appellant urged the vagueness claim in his motion to quash, and it was clear from the trial court's remarks that it felt that the statute did not provide determinate guidelines for law enforcement. See Markovich, 34 S.W.3d at 25. At the pre-trial hearing the trial judge stated: "I am going to declare the statute unconstitutional as being overbroad ... in light of the fact that anyone could decide to stop speaking, and if that were to happen, then police officers could decide to remove people simply because they were holding up signs, and in their mind, that would be interrupting a public meeting.”
¶30. We need not decide today whether a person charged solely with conduct that does not implicate First Amendment rights has standing to bring a facial challenge to a statute which under some circumstances might infringe upon First Amendment rights. In the present case, since it is clear from the charging instrument that appellee’s conduct does implicate First Amendment rights, appellee has standing to make a facial challenge to § 42.05.
¶31filed this dissenting opinion in which PRICE and JOHNSON J., joined.
¶32OPINION
¶33The crux of the majority’s opinion deals with the following questions: “Exactly how much did we rewrite § 42.05 in Morehead v. State
¶34I.
¶35In Morehead, the defendant was convicted under § 42.05 and on appeal argued that the statute was overbroad. The court of appeals held that the statute, read literally, was unconstitutionally broad, but the statute could “be narrowed to reach only unprotected expression if it is construed to prohibit only speech and physical action incompatible with the normal activity of a particular place at a particular time.”
¶36We disagreed. Although we found § 42.05 unconstitutionally overbroad, we nevertheless concluded that we did not need to invalidate the statute if it was “susceptible to a narrowing construction consistent with its language and apparent purpose.”
¶37Judge Clinton dissented. He said § 42.05 was not “readily subject to a narrowing construction.”
¶38II.
¶39We should not lightly overrule precedent.
¶40But “[s]tare decisis is not an inexorable command.”
¶41The doctrine of stare decisis is most compelling in statutory interpretation.
¶42III.
¶43Our leading case on statutory construction is Boykin v. State.
¶44*282Our holding in Boykin must be considered in connection with Supreme Court caselaw governing analysis of statutes containing constitutional issues. Justice Holmes wrote long ago that “[a] statute must be construed, if fairly possible, so as to avoid not only the conclusion that it is unconstitutional but also grave doubts upon that score.”
¶45But this doctrine “is not designed to aggravate that friction by creating (through the power of precedent) statutes foreign to those ... [that the Legislature] intended, simply through fear of a constitutional difficulty.”
¶46As the Supreme Court has stated, “[statutes should be construed to avoid constitutional questions, but this interpretative canon is not a license for the judiciary to rewrite language enacted by the legislature. Any other conclusion, while purporting to be an exercise in judicial restraint, would trench upon the legislative powers vested in Congress.”
¶47IV.
¶48It has long been a tenet of First Amendment law that, when evaluating a facial challenge to a statute, if it is “readily susceptible to a narrowing construction that would make it constitutional,” it should be upheld.
¶49But narrowing constructions should not be. adopted casually. The Supreme Court has made clear that, even when a party’s proposed narrowing construction “might avoid ... [a] constitutional problem,” .the Court is nevertheless “without power to adopt a narrowing construction of a state statute unless such a construction is reasonable and readily apparent.”
¶50*283Most importantly, a court may not add language to a statute as a way of narrowing it. The Supreme Court addressed this exact issue more than a century ago. In addressing Kentucky’s election law, the Court noted that the proposed way of limiting the statute’s reach was “not to be attained by striking out or disregarding words that are in the section, but by inserting those that are not now there.”
¶51The Kentucky Supreme Court addressed this issue more recently in Mus-selman v. Commonwealth,
¶52The Court of Appeals for the Third Circuit has also discussed this issue, setting forth two possible ways of narrowing a statute: “(a) assigning a narrow meaning to the language of the statute itself, or (b) deleting that portion of the statute that is unconstitutional.”
¶53The fact is, if additional language is required to achieve a desired construction, this means the statute is not “readily susceptible” to that construction. Rather, in conducting a true “narrowing construction,” a court should continue to focus solely on the plain language of the statute and then determine whether that language alone is susceptible to a narrowing construction. This conclusion would harmonize Boykin with the Supreme Court’s First Amendment precedent, rather than putting the two at odds.
¶54Finally there are problems with “saving” statutes by rewriting them. The Supreme Court explained in Reese that “[i]t would certainly be dangerous if the legislature could set a net large enough to catch all possible offenders, and leave it to the courts to step inside and say who could be rightfully detained, and who should be set at large. This would, to some extent, substitute the judicial for the legislative department of the government.”
¶55In his book The Supreme Court in the American System of Government, Justice Jackson said that “fe]very Justice has been accused of legislating and every one has joined in that accusation, of others.”
¶56V.
¶57Contrary to what we said in Morehead, § 42.05 is not at all “readily subject to a narrowing construction.” At that time, as well as now, the statute provided that “fa] person commits an offense if, with intent to prevent or disrupt a lawful meeting, procession, or gathering, he obstructs or interferes with the meeting, procession, or gathering by physical action or verbal utterance.” There is nothing about this language that even remotely purports to limit its application to “physical acts or verbal utterances that substantially impair the ordinary conduct of lawful meetings and thereby curtail the exercise of others’ First Amendment rights.” The Morehead Court created this language from whole cloth, “performing] a remarkable job of plastic surgery upon the face of the” statute.
¶58VI.
¶59I believe a statute is only “readily subject to a narrowing construction” if the language already in the statute can be construed in a narrow manner. Adding language to a statute is legislating from the bench. The Morehead Court erred by legislating and we should take this opportunity to correct that “judicial hubris.” We should not ignore Morehead’s error in “extending discredited reasoning” to a “previously unspoiled” statute. Instead, we should overrule Morehead and interpret § 42.05 purely as the Legislature wrote it. In doing so, we should find the statute unconstitutionally overbroad and vague. Because the majority concludes otherwise, I respectfully dissent.
