"Where at all possible, government must curtail speech only to the degree necessary to meet the particular problem at hand, and must avoid infringing on speech that does not pose the danger that has prompted regulation."

No. 8266
This opinion is issued in response to questions presented by Colleen Sealock, Director of the Elections Division in the
Office of Secretary of State Phil Keisling.
FIRST QUESTION PRESENTED
Does ORS 260.522,
(1)
which prohibits most anonymous signs, publications and broadcasts used in political campaigns,
violate the free speech provisions of the Oregon Constitution or the United States Constitution?
ANSWER GIVEN
The statute as currently written is unconstitutional. The liberty to produce and distribute anonymous campaign material is
protected by free speech guarantees. Under Article I, section 8, of the Oregon Constitution,
(2)
the Legislative Assembly
may not restrain "the free expression of opinion" or restrict a person's right to "speak, write, or print freely on any subject"
unless the limitation was well-established at the time that free speech guarantees entered the federal or state constitutions
and was not a limitation that those guarantees were designed to eliminate, or unless the limitation is directed not at speech
per se but at the effects of the speech. No historical exception covering anonymous political speech exists, nor does ORS
260.522 focus on effects as opposed to speech per se. Therefore, the statute violates Article I, section 8

Insco:
Where freedom is at stake, ambiguities and doubts as to statutory application, manifestly existing here, must be resolved in favor of the accused. See, e.g., United States v. Enmons, 1973, 410 U.S. 396, 411, 93 S.Ct. 1007, 35 L.Ed.2d 379; Rewis v. United States, 1971, 401 U.S. 808, 812, 91 S.Ct. 1056, 28 L.Ed.2d 493; United States v.
