Your link doesn't say what you claim it does, the CEO had nothing to do with the issue. The Board determined the salary of the CEO, signed a contract for that amount, the shareholders didn't like it, and voted against it, but as the contract was already signed, the Board couldn't do anything to stop it*, and rightly said so. The CEO didn't thumb his nose at anyone, he merely accepted the terms of the contract he had been offered.
The law you then linked to and quote states that the Shareholders can force a spill of the Board, because it's the Board that determines the Salary. However I'd not that even if they did vote out the Board, any contract previously signed would still be valid and would involve penalties and court costs for the new Board to violate.
*Without serious legal ramifications because of breach of contract.
