Final answer:
The criticism of the U.S. system of laws during the Uruguay round of GATT negotiations referred to the U.S. Commerce Department's tendency to side with U.S. companies in anti-dumping cases, amidst the broader shift from GATT to the establishment of the WTO with improved dispute settlement systems.
Step-by-step explanation:
The student's question is concerned with the issues many countries had with the U.S. system of laws during the Uruguay round of GATT negotiations. Specifically, the criticism was that the U.S. Commerce Department almost always ruled in favor of U.S. companies in dispute resolutions. This situation pertained to anti-dumping investigations and rules, a protectionist measure that implies selling goods in a foreign country cheaper than in the domestic market or below the cost of production. The broader context involves a shift from bilateral to multilateral trade agreements and the transformation of GATT into the WTO, which had a more structured dispute settlement system to address such concerns.
