It's old, it's venerated, it doesn't make a lot of sense but people love it anyway: It's the prior restraint doctrine.
According to Sir William Blackstone, the 18th-century English legal scholar who was immensely influential in the Colonies at around the time of the Revolution, "the freedom of the press" meant mostly freedom from "prior restraints" -- licensing and screening systems that would let the government prevent the publication of certain materials. But after something is published, Blackstone argued, the law could certainly punish the publisher if the publication was unlawful. Prior restraints were banned, but subsequent punishments were permitted.
As late as 1905, Justice Oliver Wendell Holmes, Jr. (later a strong supporter of a much broader free speech principle), opined that the First Amendment should be read to only bar prior restraints and not subsequent punishments. Some scholars still believe that this was the original understanding of the First Amendment, though others disagree.
Since the early 1930s, the Court has always been quite firm in condemning prior restraints, even when it was leaving open the door for speech to be punished after publication. Today, the doctrine is that prior restraints face an *extremely* strong presumption of invalidity, though theoretically they may sometimes be permissible.
The trouble is that there is really no fundamental difference between prior restraint and subsequent punishment. All punishment of speech will "restrain" speech beforehand by its deterrent effect: If the law says that publishing X will lead to a ten-year jail term, then lots of people will be restrained from publishing X (and surely this must be the law's intent).
On the other hand, almost all prior restraints operate only through subsequent punishment. If the government requires a license to put up a Web page, or demands a right to screen the page before you put it up, you can still do it -- you'll just be punished after the fact.
Many scholars today think the prior restraint doctrine is largely senseless (and some, but not all, of the authors of this series agree). The two virtues that it might have are:
We leave it to you to decide whether the prior restraint doctrine is a good idea. For now, a few words on what constitutes a prior restraint:
