Portrait of John Paul Stevens John Paul Stevens Thornburgh v. Abbott — Opinion of the Court

But general speculation that some administrative burden might ensue should not be sufficient to justify a meat-ax abridgment of the First Amendment rights of either a free citizen or a prison inmate. It is difficult even to imagine such a burden in this instance: if, as the regulations' text seems to require, prison officials actually read an article before rejecting it, the incremental burden associated with clipping out the offending matter could not be of constitutional significance.

To be sure, courts must give prison administrators some berth to combat the "Herculean obstacles" blocking their efforts to maintain security and prevent escapes or other criminal conduct, see Martinez, 416 U.S., at 404, 94 S.Ct., at 1807 and I do not object to those regulations clearly targeted at such interests. [11] Nevertheless, I agree with the Court of Appeals that provisions allowing prison officials to reject a publication if they find its contents are "detrimental" to "security, good order, or discipline" or "might facilitate criminal activity" are impermissibly ambiguous.

In lieu of Martinez's rationale, which properly takes into consideration the effects that prison regulations have on the First Amendment rights of nonprisoners, the Court applies a manipulable "reasonableness" standard to a set of regulations that too easily may be interpreted to authorize arbitrary rejections of literature addressed to inmates.
