From Justice Barrett's unanimous opinion this morning in Lindke v. Freed:
Like millions of Americans, James Freed maintained a Facebook account on which he posted about a wide range of topics, including his family and his job. Like most of those Americans, Freed occasionally received unwelcome comments on his posts. In response, Freed took a step familiar to Facebook users: He deleted the comments and blocked those who made them.
For most people with a Facebook account, that would have been the end of it. But Kevin Lindke, one of the unwelcome commenters, sued Freed for violating his right to free speech. Because the First Amendment binds only the government, this claim is a nonstarter if Freed posted as a private citizen. Freed, however, is not only a private citizen but also the city manager of Port Huron, Michigan—and while Freed insists that his Facebook account was strictly personal, Lindke argues that Freed acted in his official capacity when he silenced Lindke's speech.
When a government official posts about job-related topics on social media, it can be difficult to tell whether the speech is official or private. We hold that such speech is attributable to the State only if the official (1) possessed actual authority to speak on the State's behalf, and (2) purported to exercise that authority when he spoke on social media….
