As a private institution not beholden to the First Amendment, does Dartmouth still have an obligation to protect the freedom of expression and dissent of its students?
Because private universities are not government entities, they are not required to uphold First Amendment protections in the same manner as public universities. In other words, private institutions may generally impose stricter limitations on speech and expression that their public counterparts. Still, many private institutions adhere to freedom of expression principles and support academic freedom. Private institutions that receive federal funding must also adhere to federal anti-discrimination laws, such as those applicable under Title IX.
Dartmouth College regulations protect students' freedom of expression and dissent. This protection is memorialized in Dartmouth's Freedom of Expression and Dissent Policy. The Freedom of Expression and Dissent Policy should be read alongside Dartmouth's established standards of conduct and other relevant policies.
