Following the Supreme Court oral arguments in the health care litigation, there has been much more after-argument augmention of merits analyses than severability analyses. That is unfortunate because an incorrect approach to severability poses a more significant problem of long-term distortion of the federal judicial role in constitutional adjudication. This PPACA severability series is an attempt to continue the conversation about severability.
The primary obstacle to clear thinking about severability is a pernicious metaphor that describes invalidation as excision, which is in turn understood as a legislative function. The operation of this metaphor can be seen, for example, in a recent article by Tom Campbell, Dean and Donald P. Kennedy Chair in Law, and Professor of Economics, Chapman University: Severability of Statutes, 62 Hastings L.J. 1495 (2011).
The major premise of Dean Campbell’s article is that “[c]ourts legislate when they engage in ‘severability analysis,’ allowing part of a law to continue in force after having struck down other parts as unconstitutional.”  More precisely, ”making something into law that was not precisely the text that had been approved by Congress and signed by the President is exactly what a court does when it exercises severability authority.” [1498-99]
From this characterization of severance as creating new legislation, the rest of Dean Campbell’s argument follows. Because a presidential “line-item veto” that would accomplish such legislative handiwork without bicameralism and presentment is impermissible, so too is judicial severance that operates just like a line-item veto. Dean Campbell accordingly calls for “the complete abolition of the severability doctrine.”  According to Dean Campbell’s proposed approach, the unconstitutionality of one provision of a bill enacted into law would result in the invalidation of the entire bill of which that unconstitutional provision was a part.
As I have previously argued, the legislative characterization of the severability function is endemic in modern scholarly discourse and unreflectively implicit in existing doctrine. If one accepts Dean Campbell’s premise that severance creates new legislation, then his proposal makes sense as a way of enforcing the bicameralism and presentment requirements for creating new legislation. Dean Campbell’s proposal therefore presents a challenge to all those who accept an excision-based framework for judicial review.
In my view, however, the major premise is incorrect. A judicial refusal to enforce is not equivalent to amending the law or to exercising a judicial line-item veto. “When a court holds part of a statute unconstitutional, it issues a judgment saying so (and, in some cases, an injunction against its future enforcement). By virtue of precedent and preclusion, this judgment and the reasoning in support of it prevent the unconstitutional part of the statute from having legal effect going forward. Nothing about the actual text of the statute changes as a direct consequence of judicial action.” 85 N.Y.U. L. Rev. at 747.
The real challenge for those who advocate inseverability is to justify the transformation of (A) judicial refusal to give effect as law to one provision in resolving a case, into (B) a command that nobody (in the judiciary or otherwise) should give effect as law to any other provisions of the bill that contained the unconstitutional provision. I do not see how that justification of turning (A) into (B) can be done consistently with traditional separation of powers principles.
