Mason on Tax Discrimination in the EU

Proffessor Ruth Mason (UConn) has published an interesting report entitled In Search of Internal Consistency: Tax Discrimination in the EU, 46 Colum. J. Trans. L ___ (2007), on SSRN. Here is the abstract:

The European Union was created to bind the countries of Europe together economically to prevent future wars. Rigorous enforcement of EU nationals' fundamental economic freedoms before the European Court of Justice (ECJ) has furthered economic integration. The fundamental freedoms prohibit tax discrimination—harsher tax treatment of cross-border economic activities than purely internal activities. Critics of the ECJ argue that the Court's broad interpretation of the EC freedoms causes it to find tax discrimination where there is none. This tendency encroaches upon the sovereignty of EU member states and hampers their ability to pursue economic policy goals. In contrast, based upon a survey of all the ECJ's tax discrimination decisions, this Article offers a more nuanced critique that shows the ECJ's errors in tax discrimination cases go in both directions. In addition to finding discrimination where there is none, the Court also sometimes fails to recognize discrimination. The Court's failure to recognize tax discrimination undermines the economic integration of Europe and abridges EU nationals' personal rights.

This Article is the first to identify the Court's method of review in tax discrimination cases, the comparable internal situation test (CIST), as a principal contributor to the Court's difficulty in tax cases. Instead of CIST, the Article proposes that the ECJ borrow a method developed by the U.S. Supreme Court for tax cases arising under the Commerce Clause: the internal consistency test (ICT). Adoption of this simpler method should enable the ECJ to make more coherent tax decisions, which will promote economic efficiency and integration of the European common market.
