WTO Law and Domestic Regulation

The analyses presented address the disturbing observation that even though WTO law appreciates the regulatory leeway of WTO members in several provisions across agreements, the WTO judiciary´s case law, but also other governance mechanism active in the WTO appear to narrow down the WTO members´ regulatory autonomy and to considerably limit the space for domestic policy choices. Wide spread, even scholarly perception of the WTO, and most recently the Trump administration blame the WTO, in particular its dispute settlement branch, for being biased towards free trade and unduly restraining even legitimate domestic policies, and voiding the domestic policy space needed for addressing societal concerns and global problems. A closer look at the development of GATT/WTO law, however, reveals that, in GATT era, panels were aware of the effect their interpretations had on domestic policy space, and that some of the more recent WTO dispute settlement reports show attempts to expand WTO member´s leeway again. These observations are the starting point for an indepth analysis of the different mechanisms present in WTO law which impact on domestic regulation.
