Resumen de Constitutional courts as promoters of political centralization: lessons for the European Court of Justice

Roland Vaubel

• A cross-section analysis covering up to 42 countries and including the usual control variables shows that central government outlays as a share of general government outlays are significantly larger if the judges of the constitutional or supreme court are independent of the federal government and parliament and if the barriers to constitutional amendment are high. This evidence is consistent with the view that constitutional judges have a vested interest in centralization or that there is self-selection or both. These insights are used to draw lessons for the reform of the European Court of Justice. Self-selection should be reduced by requiring judicial experience—ideally with the highest national courts. The vested interest in centralization could be overcome by adding a subsidiarity court.
