The Federal Constitutional Court in Karlsruhe is reviewing the OMT, which was introduced last year as concerns peaked that the euro region would break apart, after plaintiffs including a lawmaker allied to Chancellor Angela Merkel brought a case against it. The as-yet-unused OMT foresees potentially unlimited purchases of bonds of debt-stricken countries that sign up to adjustment programs.

The court last year allowed Germany to ratify the 500 billion-euro ($663 billion) ESM bailout facility and the EU fiscal pact, while ruling the measures must include provisions that the country won't be forced to assume higher liabilities without its consent. The September ruling was preliminary and didn't cover the OMT bond program.
