Challenges to Germany's participation in the euro rescue funds were rejected by the nation's top court today, which said the government must seek some parliamentary approval for any future bailout payments.

The Federal Constitutional Court in Karlsruhe threw out suits targeting Germany's share of the 110 billion-euros ($155 billion) in loans for Greece from euro-region governments and the International Monetary Fund as well as a separate 750 billion-euro rescue fund approved last year to halt the spread of Greece's debt crisis.

The ruling will aid German Chancellor Angela Merkel's efforts to gain support for participation in a new round of European Financial Stability Facility programs. She pledged last week to consult lawmakers as her Cabinet agreed on a reworked plan that will raise Germany's share of EFSF loan guarantees to 211 billion euros from 123 billion euros.
