In a society that abhors censorship and in which policymakers have traditionally placed the highest value on the freedom to communicate, it is unrealistic to conclude that statutory authority to regulate conduct implicitly authorized the Executive to regulate speech.
Stevens dissent Rust v. Sullivan 500 U.S. 173 (1991)
A peculiarity of the situation is that the parents of this odd creature—the courts—do not realize, despite the labor pains of its birth, that they have brought forth a child. This article is written for the benefit of lawyers and courts of the States that have produced the new offspring, so that they may see that it is a new creature, and that it is ugly and illegitimate and ought promptly to be strangled.
Charles E. Carpenter, 17 S. Cal. L. Rev. 347 (1943-1944)
