The port authority may establish a certain fashion of operation based on the bylaws that are in place now in the neighbouring municipality or jurisdiction and then all of a sudden, if that jurisdiction were to change its bylaws, it could cause the port authority to have to make substantial and profound changes in the way it operates.
It would be completely illegal for the port authority to change any of its bylaws that would alter their operations.
I fooled the system by the wording I used.
