The Costs of Due Process
There is pressure, even from some public health professionals, to give individuals more rights under public health laws than would be required by the Constitution. Indeed, this is the central legal issue in public health law, as stated above. Some states have  amended their disease control laws to require court  hearings before public health orders are issued against  an individual. These hearings are modeled after the proceedings that are required before a mentally ill person is involuntarily committed to a psychiatric institution. Although such an expansion of individual  rights seems desirable, it comes at a high price: potential paralysis of public health enforcement.
Court hearings are expensive and time consuming.  No health department has a sufficiently large legal  staff to have a court hearing before every enforcement  action. Indeed, most health departments do not have any legal staff. They are at the mercy of city or county legal departments to provide attorneys when there is  a hearing. Because most legal departments are under staffed, public health enforcement actions usually have low priority.
Another problem with hearings is that they take time. A hearing first must be scheduled with a judge, and then the person subject to the order must be served with notice of the hearing and given time to hire an attorney and present a defense. This prevents timely restrictions that are critical to effective disease control. Courts have recognized, in their rejection of requests for bail by persons under disease control orders, that disease carriers cannot be allowed to go free while restrictions are litigated, as the following argument shows:
To grant release on bail to persons isolated and detained on a quarantine order because they have a contagious disease which makes them dangerous to others, or to the public in general, would render quarantine laws and regulations nugatory and of no avail.[Varholy v Sweat, 15 So 2d 267, 270 (Fla 1943).]
A final problem with hearings, and perhaps the most serious, is that they give the judge the opportunity to substitute her judgment for that of the public health officer. The proper role of the judge (or jury) was established in the original case ruling that involuntary immunizations are constitutionally permissible. The U.S. Supreme Court rejected the petitioner's claim that he was entitled to have a jury determine whether the state's actions were reasonable. The Court ruled that "It is no part of the function of a court or a jury to determine which of two modes was likely to be most effective for the protection of the public against disease."[Jacobson v Massachusetts, 197 US 11358, 363 (1905)]
Despite such clear judicial support for deference to agency decision makers, many judges are swayed by the emotional appeal of the case against restriction and reject the public health authority's recommendations. Such conflicts are most common in disputes over closing unsanitary restaurants owned by friends of the local politicians. They can also arise in disease control cases when there is political pressure to not restrict individuals because they belong to a politically powerful group or because the judge does not understand the danger to others posed by the infected person.
