Former Oklahoma educator Summer Boismier filed a new lawsuit in federal court last week over the state’s revocation of her teaching credentials.

In 2022, Boismier drew the ire of Ryan Walters, then secretary of education, for her classroom protest of House Bill 1775. Boismier hung paper over the bookshelves in her Norman High School English classroom and wrote ‘books the state doesn’t want you to read.’ She also posted a QR code to the Brooklyn library.

Last year, against an administrative law judge’s advice, the Oklahoma Board of Education and Walters revoked her teaching certificate.

Now, she’s suing the state Education Department, Board of Education, Walters and five former board members. In court filings, Boismier claims the board discriminated against her based on sex and race for her advocacy of marginalized people, and violated her rights to free speech and due process, among other claims.

Boismier resigned from teaching in 2022 and relocated to New York, but has since moved back to Oklahoma, the filing states. She has a pending lawsuit seeking to reinstate her teaching license in Oklahoma County. A federal judge dismissed her defamation lawsuit against Walters earlier this year.
