+        Command to mark unresolved ECJU queries as resolved.
+
+        Usually if Exporter replies to an ECJU query then that query is marked as resolved.
+        In some cases some duplicate queries are observed with the same timestamp, at this point
+        it is not certain whether they are created intentionally or because of a bug so further
+        investigation is required.
+
+        But if any case has unresolved queries it won't be visible to caseworkers and delay the process
+        hence this command is being added to mark them as resolved to allow the case to progress.
