While the Supreme Court has long held quarantines to be constitutional, it has not ruled directly on the scope of permissible quarantines. However, in the famous case of Jacobson v. Massachusetts, the Court did uphold a blanket mandatory vaccination law, under which resisters were put in jail. The principle here is the same as with quarantine – that one’s normal rights to bodily integrity are suspended by a general and serious public need, especially of an epidemiological variety.One case upholding a quarantine has facts that look strikingly like Hickox’s. In U.S. ex rel Siegel v. Shinnick, 219 F.Supp. 789 (E.D. NY 1963), the plaintiff was confined for 14 days on her return from a “smallpox infected area” abroad, despite a lack of any evidence of direct exposure or symptoms. The court upheld the action, noting:
[ The ] judgment required is that of a public health officer and not of a lawyer used to insist on positive evidence to support action; their task is to measure risk to the public and to seek for what can reassure and, not finding it, to proceed reasonably to make the public health secure. They deal in a terrible context and the consequences of mistaken indulgence can be irretrievably tragic. To supercede their judgment there must be a reliable showing of error.
