Requirements one by one
Incorporators or initial directors complete organization with bylaws
G.L. c. 156D, § 2.06 requires the incorporators or board to adopt initial bylaws. The content may manage the business and regulate corporate affairs only when it is not inconsistent with law or the articles of organization.
G.L. c. 156D, § 2.05 supplies two organization paths. Incorporators may meet before or after incorporation at the call of a majority, adopt bylaws, and elect the initial directors and named officers. They may replace that meeting with one or more written consents describing the action and signed by every incorporator.
If the incorporators do not hold that meeting, the initial directors named in the articles must meet after incorporation at the call of a majority, adopt bylaws, and elect the named officers. Either organizational meeting may occur inside or outside Massachusetts, and § 2.05 states no numeric deadline after incorporation.
Shareholders own the primary later bylaw power
G.L. c. 156D, § 10.20 places the power to make, amend, or repeal bylaws in the shareholders. The board receives concurrent power only if the articles authorize it directly or authorize the bylaws to grant it, and the board still cannot act on a provision that the Act or governing documents reserve to shareholders.
Board action also carries a disclosure step. No later than notice of the next shareholder meeting, the corporation must give every shareholder entitled to vote on bylaw amendments notice stating the substance of what the board did. Shareholders may amend or repeal any board bylaw action.
Special shareholder and board voting bylaws use dual approval tests
Under G.L. c. 156D, § 10.21, articles authorization allows the initial bylaws or a later shareholder-adopted bylaw to set a greater or lesser shareholder quorum, a greater affirmative vote, or additional voting groups. An amendment changing or deleting such a rule must satisfy both the ordinary bylaw-amendment requirements and the particular rule being changed. The board currently cannot adopt, amend, or repeal that shareholder quorum or vote bylaw.
G.L. c. 156D, § 10.22 separately permits a higher or lower board quorum or a higher board vote in the initial bylaws, by shareholder action, or by an articles-authorized board. An authorized board changing or deleting the rule must satisfy both the bylaw-amendment requirements and the particular board rule being changed. A shareholder-adopted version may specify the shareholder vote—or, when otherwise authorized, board vote—required for later change.
G.L. c. 156D, § 8.25 prevents a board committee from adopting, amending, or repealing bylaws even when the committee otherwise exercises board authority.
Current bylaws stay in Massachusetts and enter the direct records tier
G.L. c. 156D, § 16.01 requires a copy of the current bylaws or restated bylaws and all current amendments to be kept within Massachusetts at the principal office or an office of the transfer agent, secretary or assistant secretary, or registered agent.
Under G.L. c. 156D, § 16.02, a shareholder may inspect and copy that current bylaw record during regular business hours after giving written notice at least five business days before the requested date. The proper-purpose and adverse- effect conditions apply to the additional subsection (b) records, not the current-bylaw tier in subsection (a). The articles or bylaws cannot abolish or limit the statutory inspection right.
The surveyed Chapter 156D provisions impose no general signature, acknowledgment, notarization, certification, or Secretary of the Commonwealth filing requirement for the ordinary bylaw text.
Shareholder agreements and emergencies use separate rules
G.L. c. 156D, § 7.32 permits a qualifying shareholder agreement to be placed in the articles or bylaws with approval of every current shareholder. It lasts 10 years unless the agreement says otherwise and automatically terminates when shares become exchange-listed or regularly traded in a covered market. If no shares have issued, incorporators or subscribers may act as shareholders for that agreement; this is separate from initial-bylaw adoption under § 2.05.
G.L. c. 156D, § 2.07 permits the board, unless the articles provide otherwise, to adopt temporary emergency bylaws when a catastrophic event prevents ready assembly of a director quorum. Shareholders may amend or repeal them, consistent regular bylaws continue, and the emergency provisions end with the emergency.
What trips people up
The board does not receive later amendment power merely because it adopted the initial bylaws. Its § 10.20 power must trace to authorization in the articles, directly or through an articles-authorized bylaw.
The incorporator consent route is unanimous. Each incorporator must sign one or more written consents describing the organization action; § 2.05 does not state a lower consent threshold.
The current § 10.21 board prohibition is the law now. Pending H.3323 would let specified higher shareholder quorum or vote bylaws permit later board amendment or repeal, but the bill has not completed enactment.
Common questions
Can a board committee amend Massachusetts bylaws?
No. G.L. c. 156D, § 8.25 expressly excludes bylaw adoption, amendment, and repeal from committee authority.
Must a shareholder state a proper purpose to inspect current bylaws?
No proper-purpose condition appears in the direct § 16.02(a) tier for current bylaws. The shareholder must give the five-business-day written notice; the additional purpose conditions govern the subsection (b) records.
Do emergency bylaws permanently replace regular bylaws?
No. G.L. c. 156D, § 2.07 keeps consistent regular bylaws effective during the emergency and makes the emergency bylaws ineffective after it ends.
