Apparently, according to a press release of the German state department, the German government on 1. May handed over a declaration to the secretariat of the UN confirming its recognition of the compulsory jurisdiction of the International Court of Justice. For some reason, neither the ICJ itself nor the UN Secretariat issued a statement/press release on the issue.
If the press release of the state department is true, Germany becomes the 66th State having issued a declaration pursuant to Article 36 para. 2 of the Statute of the Court, according to which:
The states parties to the present Statute may at any time declare that they recognize as compulsory ipso facto and without special agreement, in relation to any other state accepting the same obligation, the jurisdiction of the Court […]
According to the statement, the declaration contained certain reservations regarding inter alia the deployment of German military forces.
