Europe and the world are eagerly awaiting the decision of Germany's Constitutional Court on September 12 regarding the European Stability Mechanism (ESM), the proposed permanent successor to the eurozone's current emergency lender, the European Financial Stability Mechanism. The Court must rule on German plaintiffs' claim that legislation to establish the ESM would violate Germany's Grundgesetz (Basic Law). If the Court rules in the plaintiffs' favor, it will ask Germany's president not to sign the ESM treaty, which has already been ratified by Germany's Bundestag (parliament).

There are serious concerns on all sides about the pending decision. Investors are worried that the Court could oppose the ESM such that they would have to bear the losses from their bad investments. Taxpayers and pensioners in European countries that still have solid economies are worried that the Court could pave the way for socialization of eurozone debt, saddling them with the burden of these same investors' losses.

The plaintiffs represent the entire political spectrum, including the Left Party, the Christian Social Union MP Peter Gauweiler, and the justice minister in former Chancellor Gerhard Schroder's Social Democratic government, Herta Daubler-Gmelin, who has collected tens of thousands of signatures supporting her case. There is also a group of retired professors of economics and law, and another of "ordinary" citizens, whose individual complaints have been selected as examples by the Court.
