It doesn’t require the EC to take action (although that is preferable). Take photos of the Chairpersons cars illegally parked and start proceeding against him yourself at CTTT. You cannot issue a NTC but you can go to arbitration and then adjudication if he persists in refusing to comply.
You cannot expect others to obey the rules if the chairperson himself ignores them.
If you can get a ruling against him he will soon start enforcing the ruling against others when he finds he cannot park in the visitor bays but others are doing.
