The Principle of Necessity in the WTO – Lessons for the GATS Negotiations On Domestic Regulation

The negotiations relating to domestic regulations in services are entering their final phase. While the implementation of their results will depend on overcoming the current stalemate in the Doha negotiating round, it becomes increasingly clear that Members will want to capitalize on the progress made in this area regardless of the fate of the Doha round.
