How can a hearing also be initiated besides by the Chairman?

A hearing can also be initiated by written notice signed by three members of a seven-member board because this reflects a factor in governance where a certain threshold of support is required to bring issues before the board. This option emphasizes the importance of collaboration and consensus among board members, ensuring that a significant portion of the board agrees on the necessity of the hearing before it can proceed.

This mechanism helps maintain order and ensures that not just any single member or a minimal number of members can unilaterally call a hearing, which could lead to inefficiencies or misuse of the process.

The other options do not appropriately align with the established procedures for initiating a hearing. They might either lack the necessary support from a designated number of members or don't reflect the formal structure required to initiate such a proceeding.
