Germany's highest court has rejected a request from a German lawmaker to block the immediate granting of guarantees from the euro zone's financial safety package, the lawmaker's office said in a statement on Thursday.

No injunction, but the decision about the constitutional complaint against the euro stabilisation mechanism remains open, the lawmaker's office said.

The constitutional court was not immediately available for comment. (Reporting by Hans-Edzard Busemann, Writing by Sarah Marsh)
