No longer subject to notification

Posted by Kashima on June 27, 2007

When a Holloywood assistant director announces to the crew and staff at a location filming in Canada, "
This will be an 11 days stay so far. Plus we are no longer subject to notification.", what does "no longer subject to notification" mean? Could someone help me with this phrase, please, because I have no background knowledge. What kind of notification does he mean?
Thank you in advance.
