Belgium's Constitutional Court rejected on Friday a request to annul a prisoner exchange treaty with Iran that could lead to a convicted Iranian diplomat being swapped for a jailed Belgian aid worker.
Belgian lawmakers cleared the treaty in July, but it has been held up due to legal challenges from an exiled Iranian opposition group.
"The Court rejects the action for annulment," the constitutional court said in a press release.
