The following editorial appeared recently in the Los Angeles Times.

From race relations to abortion to gay marriage, the Supreme Court plays a crucial role in American life. So it’s understandable that activists want to demonstrate on the grand plaza in front of the court’s building. Such a majestic backdrop lends force to a protest and increases the possibility that it will attract public attention.

Ignoring those realities and adopting a crabbed view of the 1st Amendment, the U.S. Court of Appeals for the District of Columbia Circuit last week upheld a law that bars demonstrators from gathering on the plaza, an oval terrace that is 252 feet long (at the largest part of the oval) and 98 feet wide. By contrast, under a 1972 Supreme Court ruling, demonstrators are allowed on the grounds of the U.S. Capitol.

The decision reversed a lower court ruling in favor of Harold Hodge Jr., an anti-police-brutality protester who was arrested in 2011 when he refused to leave the court grounds. Hanging from Hodge’s neck was a sign reading: “The U.S. Gov. Allows Police To Illegally Murder And Brutalize African-Americans and Hispanic People.”

Writing for a three-judge panel, Judge Sri Srinivasan concluded that the plaza wasn’t a public forum (even though tourists mingle there and attorneys holds news conferences in front of the court’s steps). He then said that the prohibition on protesters was justified because it furthers the government’s interests in “preserving the appearance and actuality of a judiciary unswayed by public opinion and pressure.”

This priggish rationalization ignores the fact that, like all federal judges, Supreme Court justices have life tenure and are blissfully free to disregard public opinion if they choose. Moreover, the Supreme Court has held that the 1st Amendment protects the right to comment on the behavior of judges and offer them advice.

In Bridges v. California, a landmark 1941 case, the court overturned a contempt-of-court citation against the Los Angeles Times for an editorial urging a judge not to grant probation to two union members convicted of assaulting nonunion truck drivers and instead to send them to prison. Justice Hugo Black said that to treat the editorial as a threat to the judicial process “would be to impute to judges a lack of firmness, wisdom or honor, which we cannot accept as a major premise.”

If Hodge ultimately appeals to the Supreme Court, the justices should likewise rule in his favor and return to the court’s long-standing principle that “debate on public issues should be uninhibited, robust, and wide-open.”
