ORDER
The opinion filed in this case on December 10, 2007, slip op. at 16135,
At slip op. 16157, line 12:
The issue of a facial vagueness challenge is not before this court. We therefore do not reach that issue.
At slip op. 16160, line 10:
Whether the outcome would be different if evidence were presented showing that “service” rendered to a designated foreign terrorist organization resulted in the receipt of money by the designated foreign terrorist organization itself is not an issue presented by this case. We therefore do not reach that issue.
With these amendments, the panel has voted to deny the petition for panel rehearing and the petition for rehearing en banc. The full court has been advised of these amendments and of the petition for rehearing en banc and no active judge has requested a vote on whether to rehear the matter en banc. (Fed. R.App. P. 35.) Future petitions for panel rehearing and future petitions for rehearing en banc will not be entertained.
The petition for panel rehearing and the petition for rehearing en banc are DENIED.
OPINION
We are once again called upon to decide the constitutionality of sections 302 and 303 of the Antiterrorism and Effective Death Penalty Act (“AEDPA”) and its 2004 amendment, the Intelligence Reform and Terrorism Prevention Act (“IRTPA”).
I. OVERVIEW
Section 302(a) of AEDPA, Pub.L. 104-132, 110 Stat. 1214 (1996), codified in 8 U.S.C. § 1189, authorizes the Secretary of State (the “Secretary”) to designate a group as a “foreign terrorist organization.” Section 303(a) makes it a crime for anyone to provide support to even the nonviolent activities of the designated organization. See 18 U.S.C. § 2339B(a). Specifically, 8 U.S.C. § 1189(a)(1) authorizes the Secretary of State
to designate an organization as a foreign terrorist organization ... if the Secretary finds that (A) the organization is a foreign organization; (B) the organization engages in terrorist activity ...; and (C) the terrorist activity or terrorism of the organization threatens the security of United States nationals or the national security of the United States.
8 U.S.C. § 1189(a)(1).
The pertinent facts may be found in prior published decisions in this case.
See Humanitarian Law Project v. Reno,
*921 Plaintiffs are six organizations, a retired federal administrative law judge, and a surgeon. The Kurdistan Workers Party, a.k.a Partiya Karkeran Kurdistan (“PKK”), and the Liberation Tigers of Tamil Eelam (“LTTE”) engage in a wide variety of unlawful and lawful activities. Plaintiffs seek to provide support only to nonviolent and lawful activities of PKK and LTTE. This support would help Kurds living in Turkey and Tamils living in Tamil Eelam in the Northern and Eastern provinces of Sri Lanka to achieve self-determination. 1
On October 8, 1997, the Secretary of State designated PKK, LTTE, and twenty-eight other foreign organizations as “foreign terrorist organizations.” See 62 Fed. Reg. 52, 650, 52,650-51 (Oct. 8, 1997). To this day, both PKK and LTTE remain on the designated foreign terrorist organization list. Plaintiffs, fearing that they would be criminally investigated, prosecuted, and convicted under section 2339B(a), have been withholding their support for the PKK and LTTE from the time they were designated as foreign terrorist organizations.
On March 19, 1998, Plaintiffs filed a complaint in the district court (CV-98-01971-ABC; appeal No. 05-56753), alleging that AEDPA violated their First and Fifth Amendment rights. Plaintiffs sought a preliminary injunction to bar the government from enforcing against them AEDPA’s prohibition against providing “material support or resources” to PKK and LTTE. In support of their motion for a preliminary injunction, Plaintiffs argued: (1) that AEDPA violated their First Amendment right to freedom of association and their Fifth Amendment right to due process because section 2339B(a) imposed a criminal penalty for their association with the designated organizations without requiring the government to prove that Plaintiffs had the specific intent to further the designated organizations’ unlawful goals; (2) that AEDPA violated their First Amendment right to association by prohibiting them from making political contributions to the designated organizations; and (3) that AEDPA violated their First and Fifth Amendment rights because it gave the Secretary of State unfettered licensing power to designate a group as a foreign terrorist organization.
In June 1998, the district court partially granted Plaintiffs’ motion for a preliminary injunction and enjoined the Attorney General’s enforcement of AEDPA with respect to its prohibition on providing “training” and “personnel” to PKK and LTTE.
See Humanitarian Law Project v. Reno,
Both parties appealed the district court’s order. On March 3, 2000, we affirmed the district court. See HLP I. In HLP I, we determined that AEDPA section 2339B is a content-neutral regulation of conduct subject to intermediate scrutiny. See id. at 1135. Further, we rejected Plaintiffs’s licensing scheme argument and held that the discretion accorded to the Secretary of State to designate a group as a foreign terrorist organization is not “unfettered” “because the regulation involves the conduct of foreign affairs” for which the courts “owe the executive branch even more latitude.” Id. at 1137. Finally, we agreed with Plaintiffs that AEDPA’s prohibitions on providing “personnel” and “training” to designated foreign terrorist organizations were unconstitutionally vague because these prohibitions could be read to criminalize conduct protected by the First Amendment. See id. at 1137-38.
After the case went back to the district court, the government moved to dismiss and both parties sought summary judgment in their favor. The district court reaffirmed its prior decision in an unpublished order.
See Humanitarian Law Project v. Reno,
No. CV 98-01971 ABC,
On October 26, 2001, Congress enacted the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act (“USA PATRIOT Act”), Pub.L. No. 107-56, § 805(a)(2), 115 Stat. 272 (Oct. 26, 2001). The USA PATRIOT Act amended AEDPA’s definition of “material support or resources” to include the prohibition against providing “expert advice or assistance” to a designated foreign terrorist organization. See 18 U.S.C. § 2339A(b) and § 2339B(g)(4).
On August 27, 2003, Plaintiffs filed a separate complaint in the district court (CV-03-06107-ABC; appeal No. 05-56846), challenging AEDPA’s ban on providing “expert advice or assistance” to a designated foreign terrorist organization. The district court found that term to be unconstitutionally vague, but not over-broad.
See Humanitarian Law Project v. Ashcroft,
On December 3, 2003, we affirmed the district court’s holding that the terms “training” and “personnel” were void for vagueness.
See Humanitarian Law Project v. United States Dep’t of Justice,
On December 17, 2004, three days after the en banc panel heard oral argument, Congress passed the Intelligence Reform and Terrorism Prevention Act (“IRTPA”) which amended AEDPA. As amended, AEDPA now provides in part:
Whoever knowingly provides material support or resources to a foreign terrorist organization, or attempts or conspires to do so, shall be fined under this title or imprisoned not more than 15 years, or both, and, if the death of any person results, shall be imprisoned for any term of years or for life.
18 U.S.C. § 2339B(a)(1) (emphasis added).
The term “material support or resources” includes:
any property, tangible or intangible, or service, including currency or monetary instruments or financial securities, financial services, lodging, training, expert advice or assistance, safehouses, false documentation or identification, communications equipment, facilities, weapons, lethal substances, explosives, personnel (1 or more individuals who may be or include oneself), and transportation, except medicine or religious materials.
18 U.S.C. § 2339A(b) (emphasis added).
In enacting IRTPA, Congress amended the definition of “material support or resources” to include an additional ban on providing “service.” See id. Congress also defined for the first time the terms “training” and “expert advice or assistance,” 18 U.S.C. § 2339(A)(b)(2)-(3), and clarified the prohibition against providing “personnel” to designated organizations, 18 U.S.C. § 2339B(h).
Post-IRTPA, “training” refers to “instruction or teaching designed to impart a specific skill, as opposed to general knowledge.” 18 U.S.C. § 2339A(b)(2). “Expert advice or assistance” encompasses “advice or assistance derived from scientific, technical or other specialized knowledge.” 18 U.S.C. § 2339A(b)(3). “Personnel” includes “1 or more individuals” who “work under th[e] terrorist organization’s direction or control or [who] organize, manage, supervise, or otherwise direct the operation of that organization.” 18 U.S.C. § 2339B(h). AEDPA, as amended by IRTPA, narrows the definition of “personnel” by providing that “[ijndividuals who act entirely independently of the foreign terrorist organization to advance its goals or objectives shall not be considered to be working under the foreign terrorist organization’s direction or control.” Id. (emphasis added).
Further, IRTPA provides that AEDPA’s prohibition on providing “material support or resources” to a designated foreign terrorist organization includes a mens rea requirement. To violate the statute, a person who provides “material support or resources” to a designated organization must know that (1) “the organization is a designated terrorist organization,” (2) “the organization has engaged or engages in terrorist activity,” or that (3) “the organization has engaged or engages in terrorism.” 2 18 U.S.C. § 2339B(a)(l).
*924 Lastly, AEDPA, as amended by IRTPA, gives the Secretary of State discretion to authorize (with the concurrence of the Attorney General) certain forms of support 3 otherwise proscribed under section 2339B(a) unless such support “may be used to carry out terrorist activity.” 18 U.S.C. § 2339B®.
Because of the amendments to AEDPA contained in IRTPA, the en banc panel, on December 21, 2004, “vacate[d] the judgment and injunction [of the
HLP II
panel] regarding the terms ‘personnel’ and ‘training,’ and remanded [this case] to the district court for further proceedings.”
See Humanitarian Law Project v. United States Dep’t of State,
On remand, the district court consolidated the two cases (the “personnel” and “training” challenge and the “expert advice and assistance” challenge). Plaintiffs also challenge IRTPA’s newly added term “service.” The parties thereafter filed cross-motions for summary judgment. On July 25, 2005, the district court granted in part and denied in part the summary judgment motions in the consolidated cases.
See Humanitarian Law Project v. Gonzales,
II. STANDARD OF REVIEW
We review the district court’s order granting summary judgment de novo.
See Balint v. Carson City,
The district court’s determination that a statute is unconstitutionally vague is reviewed de novo.
See United States v. Wyatt,
III. DISCUSSION
A. Specific Intent
In their prior appeals, Plaintiffs argued that AEDPA section 2339B(a) vio
*925
lates their Fifth Amendment due process rights because that section does not require proof of mens rea to convict a person for providing “material support or resources” to a designated foreign terrorist organization.
See HLP-II,
In December 2004, Congress passed IRTPA that revised AEDPA to essentially adopt our reading of AEDPA section 2339B to include a knowledge requirement. Thus, post-IRTPA, to convict a person for providing “material support or resources” to a designated foreign terrorist organization, the government must prove that the donor defendant “ha[d] knowledge that the organization is a designated terrorist organization, that the organization has engaged or engages in terrorist activity, or that the organization has engaged or engages in terrorism.” 18 U.S.C. § 2339B(a) (citations omitted). As explained above, on December 21, 2004, the en banc panel vacated our judgment in
HLP II,
and remanded the case to the district court for further proceedings in light of IRTPA.
See HLP en bane,
Plaintiffs argue that IRTPA does not sufficiently cure AEDPA section 2339B’s mens rea deficiency. They contend that section 2339B(a) continues to violate due process because it does not require the government to prove that the donor defendant acted with specific intent to further the terrorist activity of the designated organization. Plaintiffs urge us to invalidate the statute or, alternatively, to read a specific intent requirement into the statute.
“In our jurisprudence guilt is personal.”
Brown v. United States,
“[D]etermining the mental state required for commission of a federal crime requires ‘construction of the statute and ... inference of the intent of Congress.’ ”
Staples v. United States,
In
Liparota v. United States,
Here, AEDPA section 238933(a) already requires the government to prove that the donor defendant provided “material support or resources” to a designated foreign terrorist organization with
knowledge
that the donee organization is a designated foreign terrorist organization, or with
knowledge
that the organization is or has engaged in terrorist activities or terrorism. 18 U.S.C. § 233913(a). As amended, AED-PA section 2339B(a) complies with the “conventional requirement for criminal conduct — awareness of some wrongdoing.”
Staples,
Plaintiffs urge us to read a specific intent requirement into AEDPA section 2339B. They rely on
Scales v. United States,
At oral argument, Plaintiffs conceded that, were we to read into section 2339B a specific intent requirement that the person providing “material support or resources” do so with an intent to further the organization’s unlawful goals (terrorist activity), we would be extending Scales. Because we find that acting with “knowledge” satisfies the requirement of “personal guilt” and eliminates any due process concerns, we decline Plaintiffs’ invitation to extend the holding in Scales.
Plaintiffs also rely on what they consider “vicarious criminal liability” cases where courts required proof of intent to further the group’s illegal ends. Those cases are distinguishable. We disagree with Plaintiffs’ characterization of section 2339B(a) *927 as a statute that imposes “vicarious criminal liability.”
Vicarious liability involves holding one person accountable for the actions of another. Section 2339B(a) criminalizes the act of knowingly providing “material support or resources” to a designated foreign terrorist organization. Donor defendants are penalized for the criminal act of support. Donor defendants cannot be penalized under section 2339B(a) for the illegal conduct of the donee organization.
Ferguson v. Estelle,
Unlike the statute at issue in Ferguson, section 2339B(a) seeks to punish only those who commit the acts proscribed by the statute. In other words, a person who provides “material support or resources” to a designated foreign terrorist organization is liable for knowingly doing so in violation of section 2339B(a). Section 2339B(a) does not impose “vicarious criminal liability” because the statute cannot be invoked to punish the donor defendant for crimes committed by the donee foreign terrorist organization. A person cannot be convicted of murder under section 2339B(a) if the foreign terrorist organization committed an act of terrorism that took innocent lives. In sum, because section 2339B(a) does not impose “vicarious criminal liability,” due process is satisfied without proof of specific intent to further the organization’s illegal goals.
Finally, in enacting IRTPA, Congress explicitly stated that knowledge of the organization’s designation as a foreign terrorist organization, or knowledge of its engagement in terrorist activities or terrorism is required to convict under section 2339B(a). As the district court correctly observed, Congress could have, but chose not to, impose a requirement that the defendant act with the specific intent to further the terrorist activity of the organization, a requirement clearly set forth in sections 2339A and 2339C of the statute, but left out of section 2339B.
See DC HLP III,
Because there is no Fifth Amendment due process violation, we affirm the district court on this issue.
B. Vagueness
AEDPA section 2339B(a), as amended by IRTPA in December 2004, now criminalizes the act of knowingly providing “material support or resources” to a designated foreign terrorist organization. The amended statute defines “material support and resources” as:
any property, tangible or intangible, or service, including currency or monetary instruments or financial securities, financial services, lodging, training, expert advice or assistance, safehouses, false documentation or identification, communications equipment, facilities, weapons, lethal substances, explosives, personnel (1 or more individuals who may be or include oneself), and transportation, except medicine or religious materials.
18 U.S.C. § 2339A(b) (emphasis added).
Plaintiffs argue that this amended definition is impermissibly vague because *928 the statute fails to notify a person of ordinary intelligence as to what conduct constitutes “material support or resources.” Specifically, Plaintiffs argue that the prohibitions on providing “training,” “expert advice or assistance,” “service,” and “personnel” to designated organizations are vague because they are unclear and could be interpreted to criminalize protected speech and expression.
The Due Process Clause of the Fifth Amendment requires that statutes clearly delineate the conduct they proscribe. See
Foti v. City of Menlo Park,
Vague statutes are invalidated for three reasons: “(1) to avoid punishing people for behavior that they could not have known was illegal; (2) to avoid subjective enforcement of laws based on ‘arbitrary and discriminatory enforcement’ by government officers; and (3) to avoid any chilling effect on the exercise of First Amendment freedoms.” Id. at 638.
1. “Training ”
In
HLP I,
we held that the term “training” under AEDPA was unconstitutionally vague.
The district court again agreed with Plaintiffs. The district court held that IRTPA did not cure the vagueness of the term “training,” and enjoined the government from enforcing against Plaintiffs AEDPA’s ban on providing “training.”
See DC-HLP III,
Generally, we would start our vagueness analysis by considering the plain meaning of the language at issue. See
Johnson v. Aljian,
*929
To survive a vagueness challenge, the statute must be sufficiently clear to put a person of ordinary intelligence on notice that his or her contemplated conduct is unlawful.
See Foti,
Even if persons of ordinary intelligence could discern between the instruction that imparts a “specific skill,” as opposed to one that imparts “general knowledge,” we hold that the term “training” would remain im-permissibly vague. As we previously noted in
HLP I,
limiting the definition of the term “training” to the “imparting of skills” does not cure unconstitutional vagueness because, so defined, the term “training” could still be read to encompass speech and advocacy protected by the First Amendment.
See HLP I,
For the foregoing reasons, we reject the government’s challenge and agree with the district court that the term “training” remains impermissibly vague because it “implicates, and potentially chills, Plaintiffs’ protected expressive activities and imposes criminal sanctions of up to fifteen years imprisonment without sufficiently defining the prohibited conduct for ordinary people to understand.”
DC-HLP III,
2. “Expert Advice or Assistance ”
The district court previously invalidated the undefined term “expert advice or assistance” on vagueness grounds. The district court reasoned that the prohibition against providing “expert advice or assistance” could be construed to criminalize activities protected by the First Amendment. Id. at 1151. The government appealed. We now have the benefit of IRT-PA’s language while reviewing this appeal.
IRTPA defines the term “expert advice or assistance” as imparting “scientific, technical, or other specialized knowledge.” 18 U.S.C. § 2339A(b)(3).
The government argues that the ban on “expert advice or assistance” is not vague. The government relies on the Federal Rules of Evidence’s definition of expert testimony as testimony based on “scientific, technical, or other specialized knowledge.” Fed.R.Evid. 702;
see also Daubert v. Merrell Dow Pharm., Inc.,
We agree with the district court that “the Federal Rules of Evidence’s inclusion of the phrase ‘scientific, technical, or other specialized knowledge’ does not clarify the term ‘expert advice or assistance’ for the average person with no background in law.”
DC-HLP III,
At oral argument, the government stated that filing an amicus brief in support of a foreign terrorist organization would violate AEDPA’s prohibition against providing “expert advice or assistance.” Because the “other specialized knowledge” portion of the ban on providing “expert advice or assistance” continues to cover constitutionally protected advocacy, we hold that it is void for vagueness.
See HLP I,
The portion of the “expert advice or assistance” definition that refers to “scientific” and “technical” knowledge is not vague. Unlike “other specialized knowledge,” which covers every conceivable subject, the meaning of “technical” and “scientific” is reasonably understandable to a person of ordinary intelligence. See Houghton Mifflin Reading Spelling and Vocabulary Word Lists (5th Grade), http:// www-kes.stjohns.kl2.fl.us/wordlists/5th/ vocab2.htm (including “technical” as a fifth-grade vocabulary word); see also Tennessee Department of Education Third Grade Science Vocabulary, http://jc-schools.net/tutorials/vocab/sci-3.htm (including “scientific method” on third-grade vocabulary list).
3. “Service ”
IRTPA amended the definition of “material support or resources” to add the prohibition on rendering “service” to a designated foreign terrorist organization. There is no statutory definition of the term “service.”
Plaintiffs argue that proscribing “service” is vague because each of the other challenged provisions could be construed as a provision of “service.” The district court agreed.
We adopt the district court’s holding and its reasoning. See DC-HLP III, 380 F.Suppüd at 1151-52. The term “service” presumably includes providing members of PKK and LTTE with “expert advice or assistance” on how to lobby or petition representative bodies such as the United Nations. “Service” would also include “training” members of PKK or LTTE on how to use humanitarian and international law to peacefully resolve ongoing disputes. Thus, we hold that the term “service” is impermissibly vague because “the statute defines ‘service’ to include ‘training’ or ‘expert advice or assistance,’ ” and because “ ‘it is easy to imagine protected expression that falls within the bounds’ of the term ‘service.’ ” Id. at 1152. 8
A “Personnel ”
In HLP I, we concluded that “personnel” was impermissibly vague because the term could be interpreted to encompass expressive activity protected by the First Amendment. HLP I, 205 F.3d at *931 1137. We stated that, “[i]t is easy to see how someone could be unsure about what AEDPA prohibits with the use of the term ‘personnel,’ as it blurs the line between protected expression and unprotected conduct.” Id. We observed that “[s]omeone who advocates the cause of the PKK could be seen as supplying them with personnel.... But advocacy is pure speech protected by the First Amendment.” Id.
As stated above, in 2004, Congress passed IRTPA which amended AEDPA. IRTPA added a limitation to the ban on providing “personnel.” 18 U.S.C. § 2339B(h). Section 2339B(h) clarifies that section 2339B(a) criminalizes providing “personnel” to a foreign terrorist organization only where a person, alone or with others, “[work]s under that terrorist organization’s direction or control or ... organize^], manage[s], supervise^], or otherwise direet[s] the operation of that organization.” Section 2339B(h) also states that the ban on “personnel” does not criminalize the conduct of “[i]ndividu-als who act entirely independently of the foreign terrorist organization to advance its goals or objectives.” Id.
As amended by IRTPA, AEDPA’s prohibition on providing “personnel” is not vague because the ban no longer “blurs the line between protected expression and unprotected conduct.”
HLP I,
Because IRTPA’s definition of “personnel” provides fair notice of prohibited conduct to a person of ordinary intelligence and no longer punishes protected speech, we hold that the term “personnel” as defined in IRTPA is not vague.
C. Overbreadth
Plaintiffs argue that the terms “training,” “personnel,” “expert advice or assistance” and “service” are substantially overbroad. The district court rejected Plaintiffs’ challenge.
See DC-HLP III,
A statute is facially overbroad when its application to protected speech is “substantial, not only in an absolute sense, but also relative to the scope of the law’s plainly legitimate applications.”
Virginia v. Hicks,
We have previously held that AEDPA’s prohibition against providing “material support or resources” to a designated organization “is not aimed at interfering with the expressive component of [Plaintiffs’] conduct but at stopping aid to terrorist groups.”
HLP I,
Section 2339B(a)’s ban on provision of “material support or resources” to designated foreign terrorist organizations un-doubtably has many legitimate applications. For instance, the importance of curbing terrorism cannot be underestimated. Cutting off “material support or resources” from terrorist organizations deprives them of means with which to carry out acts of terrorism and potentially leads to their demise. Thus, section 2339B(a) can legitimately be applied to criminalize facilitation of terrorism in the form of providing foreign terrorist organizations with income, weapons, or expertise in constructing explosive devices.
See HLP I,
The Supreme Court cautioned in
Hicks
that “there are substantial social costs
created
by the overbreadth doctrine when it blocks application of a law to constitutionally unprotected speech, or especially to constitutionally unprotected conduct.”
Hicks,
Moreover, although Plaintiffs may be able to identify particular instances of protected speech that may fall within the statute, those instances are not substantial when compared to the legitimate applications of section 2339B(a).
Thus, because AEDPA section 2339B is not aimed at expressive conduct and because it does not cover a substantial amount of protected speech, we hold that the prohibition against providing “material support or resources” to a foreign terrorist organization is not facially overbroad.
D. Licensing Scheme
IRTPA added section 2339B(j), an entirely new section, to AEDPA. Section 2339B(j) allows the Secretary of State, with the concurrence of the Attorney General, to grant approval for individuals and organizations to carry out activities that would otherwise be considered providing “material support or resources” to designated foreign terrorist organizations. 18 U.S.C. § 2339B(j). Section 2339B(j) states that no one can be prosecuted under the terms “ ‘personnel,’ ‘training,’ or ‘expert advice or assistance’ if the provision of that material support or resources to a foreign terrorist organization was approved by the Secretary of State with the concurrence of the Attorney General.” 18 U.S.C. 2339B(j). The exception limits the scope of discretion by providing only that the “Secretary of State may not approve the provision of any material support that may be used to carry out terrorist activity.” Id.
Plaintiffs argue that this provision constitutes an unconstitutional licensing scheme. We disagree.
Courts may entertain pre-en-forcement facial challenges to a licensing scheme where the law has a “close enough nexus to expression, or to conduct commonly associated with expression, to pose a real and substantial threat of the identified censorship risks.”
City of Lakewood v. Plain Dealer Publ’g Co.,
In our first decision, we rejected Plaintiffs’ challenge to the licensing scheme in another portion of AEDPA that allows the Secretary of State to designate a group as a foreign terrorist organization.
See HLP I,
Section 2339B(j) gives the Secretary of State the discretion to approve the provision of “material support or resources.” It does not regulate speech per se. Rather, the statute permits the Secretary of State to authorize the otherwise prohibited provision of “material support or resources” to a designated foreign terrorist organization. Indeed, we clarified in
HLP I
that contributions of “material support or resources” to foreign entities designated as foreign terrorist organizations should
not
be equated with political expression and association itself, even if such organizations are engaged in political expression.
See HLP I,
We recognize that it is possible for the Secretary to exercise his or her discretion in a way that discriminates against the donor of “material support or assistance.” For example, the Secretary could conceivably exempt from prosecution a person who teaches peacemaking skills to members of Hezbollah, but deny Plaintiffs immunity from prosecution if they teach the same peacemaking skills to PKK. However, when evaluating the constitutionality of a licensing scheme, we look at how closely the prior restraint, on its face, regulates constitutionally protected activity. Here, even though it is possible for the Secretary to refuse to exercise his or her discretion to exempt from prosecution a disliked speaker, any such power is incidental. The statute does not give the Secretary “substantial power to discriminate based on the content or viewpoint of speech” or the identity of the speaker. Id. (emphasis added).
Moreover, in Plaintiffs’ case, any potential for content or viewpoint-based discrimination or discrimination based on the identity of the speaker is significantly reduced because the government is enjoined from enforcing those provisions of the statute we hold vague. Thus, because Plaintiffs are already immune from prosecution for protected speech, the danger that the Secretary can base his or her exercise of discretion on Plaintiffs’ identity or the content or viewpoint of Plaintiffs’ message is almost non-existent.
Accordingly, we affirm the district court’s holding that section 2339B(j) does not have a close enough nexus to protected speech to allow a facial challenge.
IV. CONCLUSION
For the foregoing reasons, the judgment of the district court is AFFIRMED.
Notes
. Plaintiffs who support PKK want: (1) to train members of PKK on how to use humanitarian and international law to peacefully resolve disputes, (2) to engage in political advocacy on behalf of Kurds who live in Turkey, and (3) to teach PKK members how to petition various representative bodies such as the United Nations for relief. Plaintiffs who support LTTE want: (1) to train members of LTTE to present claims for tsunami-related aid to mediators and international bodies, (2) to offer their legal expertise in negotiating peace agreements between the LTTE and the Sri Lankan government, and (3) to engage in political advocacy on behalf of Tamils who live in Sri Lanka.
. This language essentially adopts our holding in HLP II, where we held that “to sustain a
*924
conviction under § 2339B, the government must prove beyond a reasonable doubt that the donor had knowledge that the organization was designated by the Secretary as a foreign terrorist organization or that the donor had knowledge of the organization's unlawful activities that caused it to be so designated.”
HLP II,
. The other two cases Plaintiffs rely on,
Staples,
. Although section 2339B(a) does not punish mere membership, the statute does prohibit the paying of membership dues.
See HLP I,
. The issue of a facial vagueness challenge is not before this court. We therefore do not reach that issue.
. In deciding previously raised challenges such as vagueness, we are bound by our decision in
HLP I. See Murdoch v. Castro,
. Whether the outcome would be different if evidence were presented showing that “service” rendered to a designated foreign terrorist organization resulted in the receipt of money by the designated foreign terrorist organization itself is not an issue presented by this case. We therefore do not reach that issue.
