The Bylaws Amendment
The bylaws amendment can usually be performed by the shareholders as well as the directors, except for the cases where the articles of incorporation or the shareholders state otherwise.
A bylaw requesting a larger quorum or voting for shareholders can be requested in the articles of incorporation. However, this statement is not necessarily adopted, revoked or amended by the directors.
It is exclusive to the shareholders to amend or revoke adopted bylaws requiring a larger quorum or voting for the board of directors.
Conversely, if the bylaws is adopted by the board of directors, it can only be amended or revoked by them.
