Port Huron

The court did not apply the new standard to the cases before them, involving a city manager in Port Huron, Mich., and two members of a school board in California.

“The whole idea of S.D.S. began with the idea of, ‘We need a new way of being on the left, a new vocabulary, a new strategy,’” said Mr. Flacks, who helped write the group’s manifesto, the Port Huron Statement, in 1962.

Freed, the city manager of Port Huron, Michigan, used a Facebook page to sometimes post about government business but mostly to post personal updates.

The second case involves a Michigan man's appeal after a lower court rejected his lawsuit against a Port Huron city official who blocked him on Facebook.

In the Michigan case, Port Huron resident Kevin Lindke sued after City Manager James Freed blocked him from his public Facebook page following critical posts involving the COVID-19 pandemic.
