REINHARDT, Circuit Judge:

Moishe Meyer Rosen, chairman of Jews for Jesus, arrived at Portland International Airport by plane and started distributing religious literature in the airport terminal. He was arrested for violating an ordinance requiring advance registration by those desiring to exercise first amendment rights at the terminal. The ordinance provides for (1) one business day's notice of an intent to distribute literature, picket, demonstrate, or "otherwise communicate with the general public" and (2) advance disclosure of the names, addresses, and telephone numbers of the sponsoring person and "responsible" person.

Rosen brought suit for declaratory and injunctive relief, claiming that the ordinance is unconstitutional on its face under the first and fourteenth amendments. The district court upheld the ordinance and granted summary judgment for the defendants. Rosen appealed.

The distribution of literature is a form of communication protected by the first amendment. Lovell v. City of Griffin, 303 U.S. 444, 58 S.Ct. 666, 82 L.Ed. 949 (1938). The first amendment is to be given full effect in the public areas of airport terminal buildings. Kuszynski v. City of Oakland, 479 F.2d 1130 (9th Cir. 1973); Chicago Area Military Project v. City of Chicago, 508 F.2d 921 (7th Cir. 1975). However, the regulation of activity that interferes with the normal use of an airport facility is a proper governmental function. The issue before us then is whether a public agency may regulate activity protected by the first amendment in the manner provided in the challenged ordinance.

The Port of Portland contends that the ordinance, although it affects the exercise of first amendment rights, is justified. The Port asserts the need for advance notice when activity potentially disruptive of normal airport business will occur, so that it may take adequate precautions to preserve the peace. It also suggests that advance notice may enable it to avoid the conflicts that might arise if several groups demonstrated at the same time. Finally, it argues that requiring the names, addresses, and telephone numbers of sponsoring and "responsible" persons will help it to assess the possibility of disruption and will assist in its efforts to make arrangements with those persons for the orderly and peaceful use of the airport's facilities.

Rosen contends that both the advance notice and the identification requirements of the ordinance have a "chilling effect" on free speech. He argues that a public agency may not compel an individual to register with local authorities as a condition to the exercise of free speech rights. He also urges that compulsory disclosure of the identity of sponsors and "responsible" persons is unconstitutional because those communicating with the public have a right to maintain their anonymity.

We begin with the general principles that govern the analysis of statutes or ordinances that regulate or infringe upon the exercise of first amendment rights. Any such law "must survive the most exacting scrutiny." Buckley v. Valeo, 424 U.S. 1, 64, 96 S.Ct. 612, 656, 46 L.Ed.2d 659 (1976). First, the law is presumptively unconstitutional and the state bears the burden of justification. Kuszynski v. City of Oakland, 479 F.2d 1130, 1151 (9th Cir. 1973). Second, the law must bear a "substantial relation," Gibson v. Florida Legislative Commission, 372 U.S. 539, 546, 83 S.Ct. 889, 893, 9 L.Ed.2d 929 (1963), to a "weighty" governmental interest. See Cox v. Louisiana, 379 U.S. 536, 85 S.Ct. 453, 13 L.Ed.2d 471 (1964). The law cannot be justified merely by a showing of some legitimate governmental interest." Buckley v. Valeo, 424 U.S. at 64, 96 S.Ct. at 656. Third, the law must be the least drastic means of protecting the governmental interest involved; its restrictions may be "no greater than necessary or essential to the protection of the governmental interest." Baldwin v. Redwood City, 540 F.2d 1360, 1367 (9th Cir. 1976). Fourth, the law must be drawn with "narrow specificity." Hynes v. Mayor and Council of Borough of Oradell, 425 U.S. 610, 96 S.Ct. 1755, 48 L.Ed.2d 243 (1976); NAACP v. Button, 371 U.S. 415, 83 S.Ct. 328, 9 L.Ed.2d 405 (1963). See also Hudson Gas Electric Corp. v. Public Service Commission of New York, 447 U.S. 557, 100 S.Ct. 2343, 65 L.Ed.2d 341 (1980).

Moreover, any law which imposes a "prior restraint" on the exercise of first amendment rights comes to this Court "with a heavy presumption against its constitutional validity." Vance v. Universal Amusement Co., Inc., 445 U.S. 308, 317, 100 S.Ct. 1156, 1161, 63 L.Ed.2d 413 (1980), quoting Bantam Books, Inc. v. Sullivan, 372 U.S. 58, 70, 83 S.Ct. 631, 639, 9 L.Ed.2d 584 (1963); Nebraska Press Ass'n v. Stuart, 427 U.S. 539, 558, 96 S.Ct. 2791, 2802, 49 L.Ed.2d 683 (1975); New York Times Co. v. United States, 403 U.S. 713, 714, 91 S.Ct. 2140, 2141, 29 L.Ed.2d 822 (1970); Organization for a Better Austin v. Keefe, 402 U.S. 415, 419, 91 S.Ct. 1575, 1577, 29 L.Ed.2d 1 (1970). The presumption is heavier against "prior restraints," and the protection therefore greater, because "prior restraints on speech and publications are the most serious and the least tolerable infringement on First Amendment rights." Nebraska Press Ass'n v. Stuart, 427 U.S. at 559, 96 S.Ct. at 2802.

With these general principles in mind, we turn to an analysis of the constitutionality of the specific requirements of the ordinance.

I. [9] The Advance Notice Requirement

We find the requirement of advance registration as a condition to peaceful pamphleteering, picketing, or communicating with the public to be unconstitutional. The United States Supreme Court held more than thirty-five years ago that persons desiring to exercise their free speech rights may not be required to give advance notice to the state. Thomas v. Collins, 323 U.S. 516, 65 S.Ct. 315, 89 L.Ed. 430 (1944). In Thomas, the Court said:

If the exercise of the rights of free speech and free assembly cannot be made a crime, we do not think this can be accomplished by the device of requiring previous registration as a condition for exercising them and making such a condition the foundation for restraining in advance their exercise and for imposing a penalty for violating such a restraining order. So long as no more is involved than exercise of free speech and free assembly, it is immune to such a restriction. If one who solicits support for the cause of labor may be required to register as a condition to the exercise of his right to make a public speech, so may he who seeks to rally support for any social, business, religious or political cause. We think a requirement that one must register before he undertakes to make a public speech to enlist support for a lawful movement is quite incompatible with the requirements of the First Amendment.

Id. at 540, 65 S.Ct. at 327 (emphasis added).

While Thomas preceded the cases cited for the general principles we noted earlier, it is consistent with the later first amendment cases, and it mandates our decision today. In Thomas, the Court classified the requirement of previous registration as a prior restraint. The Court recently characterized the holding in Thomas as follows: " Thomas held unconstitutional a prior restraint in the form of a registration requirement for labor organizers." Buckley v. Valeo, 424 U.S. at 81, 96 S.Ct. at 664.

The Port points to a few narrow exceptions to the Thomas rule in an attempt to justify its regulations. These exceptions all involve overwhelming governmental interests and precisely tailored regulations; none is applicable to the case before us.

The Port states, correctly, that advance notice provisions may be included in parade permit ordinances. See, e. g., Cox v. Louisiana, 379 U.S. at 558, 85 S.Ct. at 466. The governmental interest in regulating parades, when large groups use public streets and disrupt traffic by causing major arteries to be closed and transportation rerouted, is apparent. However, the ordinance before us regulates far more than mass conduct that necessarily interferes with the use of public facilities. It regulates all forms of communication with the public by groups and individuals. Any person who wishes to communicate with the public, by uttering a few words, by silently distributing literature, or "otherwise," is subject to regulation. The Port has failed to demonstrate any interest in regulating individuals or small groups that is comparable to that involved in the regulation of parades. Thus, the parade case exception simply does not apply.

Next, the Port cites an exception permitting advance notice requirements for demonstrations in the environs of the White House. See A Quaker Action Group v. Morton, 516 F.2d 717, 735 (D.C.Cir. 1975); A Quaker Action Group v. Hickel, 421 F.2d 1111, 1119 (D.C.Cir. 1970). The exception was made because of the unique importance attached to assuring the safety of the President. The Port has no similar justification for regulating expression in the manner provided in the challenged ordinance.

Finally, the Port argues that some speakers, by the nature of their message, need extra police protection and that advance notice would be helpful. We acknowledge the legitimacy of the Port's interest and recognize that many of those who communicate with the public, whether they represent Jews for Jesus, the Ku Klux Klan, the Socialist Workers' Party, or the Moral Majority, may deeply offend or antagonize members of the public. We cannot agree, however, that this interest of the Port justifies the infringement of fundamental first amendment rights. "`[A] function of free speech under our system of government is to invite dispute. It may indeed serve its high purpose best when it induces a condition of unrest, creates dissatisfaction with conditions as they are, or even stirs people to anger . . . .' Terminello v. Chicago, 337 U.S. 1, 4-5 [69 S.Ct. 894, 895-896, 93 L.Ed. 1131]." Edwards v. South Carolina, 372 U.S. 229, 237-238, 83 S.Ct. 680, 684 (1963). To preserve this important function, it is the duty of the state to protect, rather than restrict, those who express unsettling views. Edwards, Thus, the problem of police protection must be addressed through methods that do not offend the Constitution.

Advance notice or registration requirements drastically burden free speech. They stifle spontaneous expression. They prevent speech that is intended to deal with immediate issues. In addition, the ordinance before us requires every person who wishes to exercise his or her free speech rights to make a trip to the airport at least one business day in advance; it requires the person to obtain a copy of the regulations and fill out the requisite forms with the Port before the advance notice deadline. The overall effect of the advance notice requirement is seriously to discourage "political, religious, social [and] economic" speech. The Port's interest in knowing in advance what type of free speech activities may occur at the airport is insufficient to justify an ordinance so broad in its application and with so chilling an impact on the exercise of first amendment rights.

While we view the ordinance as imposing a "prior restraint" and treat it as such, we would reach the same result even if we did not so view it. The ordinance, for reasons which we have expressed previously, fails to meet the rigid standards applicable to any statutes or ordinances which regulate first amendment rights. We note that the ordinance lies somewhere between the classic prior restraint cases in which speech is totally prohibited, see, e. g., New York Times Co. v. United States, 403 U.S. 714, 91 S.Ct. 2141 (1971); Near v. Minnesota, 283 U.S. 697, 51 S.Ct. 625, 75 L.Ed. 1357 (1938), and the classic "time, place, and manner" cases in which the time, location, or volume of speech are regulated, see, e. g., Kovacs v. Cooper, 336 U.S. 77, 69 S.Ct. 448, 93 L.Ed. 513 (1949). Viewed realistically, the ordinance imposes a "prior restraint" intended to permit efficient "time, place and manner" regulation. In this respect, it bears some similarities to the parade cases, and under some circumstances such a "prior restraint" is permissible. See Cox v. New Hampshire, 312 U.S. 569, 61 S.Ct. 762 (1941). However, such exceptions to the "prior restraint" rule are narrowly limited, and carefully circumscribed, and are permitted only when the infringement is minimal and there is a compelling governmental interest which cannot be protected by any other means. First amendment rights constitute the heart of our system of democratic government. The dangers that exceptions to the "prior restraint" rule pose to our democracy are all too obvious. Any "prior restraint," therefore, must be held unconstitutional, unless no other choice exists.

II [19] The Identification Requirement

The requirement that those desiring to exercise free speech rights identify themselves and supply the names, addresses, and telephone numbers of sponsoring or responsible persons also has a "chilling effect" on free speech, and is unconstitutional. In Talley v. California, 362 U.S. 60, 80 S.Ct. 536, 4 L.Ed.2d 559 (1960), the United States Supreme Court stated the basic rule of law that is applicable here. In that case, the Court invalidated an ordinance that prohibited the distribution of pamphlets unless they contained the names of the persons who prepared, distributed, and sponsored them. The Court held that the identification requirement of the ordinance imposed unjustified burdens on the right of free expression and violated the first amendment. The Court said:

There can be no doubt that such an identification requirement would tend to restrict freedom to distribute information and thereby freedom of expression . . . .

Anonymous pamphlets have played an important role in the progress of mankind. Persecuted groups and sects from time to time throughout history have been able to criticize oppressive practices and laws either anonymously or not at all.

Id. at 64, 80 S.Ct. at 538. The specific reason which the Court stated for holding the ordinance unconstitutional was "identification and the fear of reprisal might deter perfectly peaceful discussions of public matters of importance." Id. at 65, 80 S.Ct. at 539.

The Port argues that the recent decision of the Supreme Court in Buckley v. Valeo, 424 U.S. 1, 96 S.Ct. 612, 46 L.Ed.2d 659 (1976) supports its contention that identification requirements are constitutional. We disagree. We do not read Buckley as modifying the Talley rule that the government may not compel those who speak or publish to identify themselves or their sponsors.

In Buckley, the Court held that provisions of the Federal Election Law limiting campaign expenditures violated the first amendment, but upheld provisions requiring disclosure to the Federal Election Commission by every person who makes "contributions or expenditures" aggregating over $100. The only challenge to the disclosure provision in Buckley was that it was overbroad in its application to minor parties and independent candidates; appellants argued for a blanket exemption for minor parties and independent candidates.

In Buckley, the Court held that the campaign contributions disclosure requirement was justified by the overwhelming governmental interests in informing voters and deterring corruption and undue influence — interests that the Court found essential to the "`free functioning of our national institution.'" 424 U.S. at 66, 96 S.Ct. at 657. The Court then stated that the requirement imposed "insignificant burdens on individual rights.'" id. at 68, 96 S.Ct. at 658, but that if the requisite factual showing of "chill and harassment" were made, the provision would be unconstitutional as applied, id. at 74, 96 S.Ct. at 661. Additionally, the Court noted that "disclosure requirements — certainly in most applications — appear to be the least restrictive means of curbing the evils of campaign ignorance and corruption that Congress found to exist." Id. at 68, 96 S.Ct. at 658. Thus, Buckley constitutes a narrow, limited exception to the general principles set forth in Talley.

The Port has no interest comparable to those protected by the Federal Election Law. The governmental interest in assuring that those who use the Portland airport are not inconvenienced is simply not of the same order as the governmental interest in protecting the integrity of our national electoral process. Moreover, the realities of "chill and harassment" inherent in the ordinance go far beyond those inherent in the case of the compulsory disclosure of campaign contributions. Although the disclosure provisions in Buckley apply to minority parties and candidates, their principal impact is on those expressing traditional political views. The ordinance, by regulating free expression in the public areas of an airport, affects most frequently those who advocate unpopular causes. It is those who seek to change the status quo who have historically taken to the streets or other public places to promote their causes. Those who are satisfied with our society as it is, normally use other forums. Because the expression of dissident or "unsettling" views, by its very nature, invites retaliation and oppression, the identification requirement of the ordinance presents substantial dangers of "chill and harassment" that simply do not exist in the case of compulsory disclosure of campaign contributions. Thus, the Buckley exception to the general principles set forth in Talley is inapplicable to the case presently before us.

The Port seeks to bring its identification requirement within other narrow exceptions to the general rule. The Port cites the parade and White House cases for the proposition that the identification requirements are constitutional. For the same reasons that they were of no assistance to the Port's argument with respect to advance notice, they are unpersuasive here.

Identification requirements impose heavy burdens on the exercise of first amendment rights. The right of those expressing political, religious, social or economic views to maintain their anonymity is historic, fundamental, and all too often necessary. The advocacy of unpopular causes may lead to reprisals — not only by government, but by employers, colleagues, or society in general. While many who express their views may be willing to accept these consequences, others not so brave or not so free to do so will be discouraged from engaging in public advocacy. The Port's interests underlying the identification requirement are insufficient to justify an ordinance so broad in its application and with so chilling an effect.

III [28] Conclusion

Both the advance notice and the identification provisions of the challenged ordinance violate the United States Constitution. Following the mandates of Thomas v. Collins, and Talley v. California, we hold that persons desiring to exercise their free speech rights may not be required to give advance notice and to identify themselves and their sponsors to Port authorities. The governmental interests urged by the Port represent legitimate concerns, but they do not justify the ordinance's infringement of first amendment rights.

The order of the district court is reversed and remanded with instruction to enter summary judgment for appellant.
