Pennsylvania: Corporate Bylaws Adoption and Amendment Requirements

Requirements one by one

Initial adoption is part of the organization meeting

Under 15 Pa.C.S. § 1310, the initial directors hold the post-formation
organization meeting; if the articles name no directors, the incorporators hold
it instead. The statute says the meeting “shall be held” for adopting bylaws and
treats those initial bylaws as shareholder-adopted for later statutory purposes.

Any initial director or qualifying incorporator may call the meeting and must
give every other participant at least five days' written notice stating the time
and place. An incorporator may act personally, by written consent, or by signed
proxy. The section does not extend that incorporator-specific consent sentence to
initial directors.

Shareholder amendment requires informative notice

Section 15 Pa.C.S. § 1504 gives shareholders the continuing power to adopt, amend, and
repeal bylaws. For action at a shareholder meeting, the written notice must say
that bylaw action is a purpose of the meeting and must include the proposed
amendment or a summary of the changes. A change takes effect when adopted unless
the adopting resolution provides otherwise.

The bylaws may expressly vest adoption and amendment authority in the board, but
shareholders remain able to change the board's action. The board cannot use that
delegation for a subject the statute expressly commits to shareholders.

Higher-vote provisions protect themselves

The ordinary shareholder vote under 15 Pa.C.S. §§ 1757 and 1766 is a majority
of votes cast at a meeting, with consent routes available without one, subject
to a shareholder-adopted bylaw or another Title 15 rule. A shareholder-adopted
bylaw may require a higher number or percentage. Under § 1504(d), the higher-vote
provision generally cannot be amended or repealed by a lesser vote unless the
shareholder-adopted bylaw itself provides otherwise.

Pennsylvania also uses 15 Pa.C.S. §§ 1723, 1727, 1729, and 1731 for board-size,
quorum, director-vote, and committee rules. A shareholder-adopted bylaw may vary
the one-vote-per-director default; ordinary board quorum and action defaults
yield to the bylaws, but a committee remains unable to adopt, amend, or repeal
bylaws.

Shareholders can demand the current text

Pennsylvania does not prescribe a general signature, acknowledgment,
notarization, or Department of State filing for ordinary bylaws in §§ 1310 and
1504. It does prescribe access: § 1508(c.3) gives every shareholder the right to
receive promptly after demand, without charge, a record-form copy of the currently
effective bylaws. A court must summarily order production unless the corporation
shows that the requester is not a shareholder.

What trips people up

Emergency bylaws use a separate route. Unless the ordinary bylaws restrict the
power, § 1509(a) lets the board adopt emergency rules for calls, quorum, and
substitute directors, subject to shareholder change or repeal. The emergency
bylaws expire when the statutory emergency ends, while consistent ordinary
bylaws remain in effect.

A closely held shareholder agreement can also change the governance map.
Section 15 Pa.C.S. § 1725(b)(3) recognizes an agreement assigning all director powers and
duties to persons other than directors. That special arrangement should not be
read into the ordinary corporation's bylaw rules.

Common questions

Who adopts the first Pennsylvania bylaws?

The initial directors do, unless the articles name no directors. In that case,
§ 1310 assigns the organization meeting and initial adoption to the incorporator
or incorporators.

Can shareholders amend bylaws without a meeting?

Yes. Section 15 Pa.C.S. § 1766 permits unanimous record-form consent unless the bylaws
restrict it; the bylaws may also authorize consent by the minimum vote that would
approve the action at a meeting, subject to the statute's notice rules.

Must the corporation give a shareholder a copy of the bylaws?

Yes. Section 15 Pa.C.S. § 1508(c.3) requires a prompt, free record-form copy of the current
text after any shareholder's demand.
