The ICJ yesterday stayed the execution of Jadhav, sentenced to death by a Pakistan military court which said he was an Indian spy.
Currently, there are 15 cases, including Jadhav's, before the ICJ. Of these seven are about maritime and territorial dispute.
An information officer at the ICJ told PTI the number of cases at The Hague was increasing steadily, but did not give figures.
"Since the ICJ has almost a universal jurisdiction, we get a varied number of cases, but most of these matters relate to land and sea boundary," the official said.
