A federal judge has sided with a Hillsborough County transgender high school teacher by barring Florida education officials from enforcing a section of a state parental rights law on pronoun use against the teacher.

Judge Mark Walker of the Northern District of Florida approved a preliminary injunction in an April 9 opinion for educator Katie Wood. A section of the state’s Parental Rights in Education Act violates Wood’s First Amendment right of free speech and expression, Walker said.

The law subjects Florida educators to possible dismissal or loss of their teaching credential if they use pronouns that don’t reflect their biological sex. Wood reflected on Walt Whitman’s “Song of Myself” in granting the injunction.
