A 6.03 Prisoner/Detainee First Amendment Retaliation Claim is a legal claim based on the First Amendment of the United States Constitution. It is a type of civil rights claim that prisoners and detainees can bring against prison or detention facility officials for retaliating against them for exercising their First Amendment rights. These rights include freedom of speech, freedom of the press, and freedom of assembly. To succeed in such a claim, the prisoner or detainee must prove that the retaliation was in response to an exercise of a First Amendment right, and that the retaliatory action was deliberate and malicious. There are three types of 6.03 Prisoner/Detainee First Amendment Retaliation Claims: verbal, written, and physical. A verbal claim is one in which the prisoner or detainee alleges that they were verbally punished or threatened for exercising their First Amendment rights. A written claim is one in which the prisoner or detainee alleges that they were punished or threatened in writing for exercising their rights. A physical claim is one in which the prisoner or detainee alleges that they were physically punished or threatened for exercising their First Amendment rights.
