This
Article, by Greg Shaffer and Joel Trachtman, makes the important point that choices in treaty drafting and judicial interpretation allocate authority. For example, a choice for rules (instead of standards) or reference to non-WTO norms and expert advice (instead of WTO law only) allocates authority, respectively, to negotiators (instead of the judiciary) and to other bodies or experts (instead of the WTO). This is clear and convincing. From there, however, the authors make an extra and less convincing step: after (descriptively) linking choice to authority they then (normatively) link type of authority to welfare and participation levels arguing, for example, that treaty drafters (setting rules) can be presumed to “maximize welfare” and offer more “transparency, accountability, and legitimacy” than the judiciary (applying standards) (p. 111). A similar hierarchy is presumed putting the WTO above standard-setting bodies such as Codex or the ISO, on the view that the latter “evade the need for consensus within the WTO” (p. 113) and are “subject to capture by certain interests” (p. 114).
I find it extremely difficult to make such generalizations about which type of authority is “better” in welfare and participation terms (Instead of gauging the
consequences of interpretative choices it may be more productive to think about the underlying
reasons for such choices, as I tried to do
here with my co-author Manfred Elsig).
Today’s reality is that authority flows from an increasing diversity of sources (national & international; public & private; political, judicial & expertise etc.). Unless one makes the broadest of assumptions (e.g., “if we ignore strategic problems and asymmetric allocation of power”, at p. 111; elsewhere, equating all of WTO law to trade liberalization and on that basis implying that the WTO is more “efficient”, p. 132), it no longer makes sense to presume that one source is, by definition, “better” than another (e.g. that negotiators or the WTO do a “better job” than judges, experts or other institutions). It all depends on the task at hand (for some things politicians are better; for others, judges, experts or the market) and the detailed set up of the authority in question (how does it operate; who is included; what is its reputation and support?), rather than its type. Nor do we have to make a binary choice between this or that authority: the WTO can refer to outside standards yet at the same time exercise judicial control over those standards (as the recent Panel on
US – Tuna Label did, checking the inclusiveness and transparency of the standard); it can refer to scientific or economic experts for factual matters, defer to national authorities for appropriate levels of protection but leave decisions on legal criteria in the hands of WTO panels.
