Piercing the Corporate Veil
Piercing the corporate veil is an equitable doctrine that allows courts to disregard the separate legal identity of a corporation and hold shareholders personally liable for corporate obligations. Courts typically apply a multi-factor test examining whether the corporation was used as a mere alter ego or instrumentality of the shareholder, looking at factors such as commingling of funds, failure to observe corporate formalities, undercapitalization, and use of the corporate form to perpetrate fraud or injustice. The doctrine is applied sparingly because it undermines the fundamental principle of limited liability, and the burden falls on the party seeking to pierce the veil to demonstrate that respecting the corporate form would sanction fraud or promote injustice.
Business Judgment Rule
The business judgment rule is a judicial presumption that in making a business decision, the directors of a corporation acted on an informed basis, in good faith, and in the honest belief that the action taken was in the best interest of the company. As established in Smith v. Van Gorkom, the rule shields directors from liability for decisions that turn out poorly, provided the directors were disinterested, adequately informed, and rationally believed the decision served a corporate purpose. To overcome this presumption, a plaintiff must demonstrate that the directors breached their fiduciary duties of care or loyalty, at which point the burden shifts and the court may apply the more demanding entire fairness standard of review.
Duty of Loyalty
The duty of loyalty is a fiduciary obligation requiring corporate directors and officers to act in the best interest of the corporation and its shareholders rather than in their own self-interest. As articulated by Judge Cardozo in Meinhard v. Salmon, fiduciaries owe 'the punctilio of an honor the most sensitive' and must refrain from self-dealing, usurping corporate opportunities, and competing with the corporation. When a director engages in a transaction where they have a personal financial interest, the transaction is subject to heightened judicial scrutiny under the entire fairness standard unless it has been properly approved by disinterested directors or shareholders after full disclosure.
Duty of Care (Corporate)
The corporate duty of care requires directors to act with the care that a reasonably prudent person would use in similar circumstances and to make informed decisions by considering all material information reasonably available before acting. In Smith v. Van Gorkom, the Delaware Supreme Court held that the Trans Union board breached its duty of care by approving a merger after only two hours of deliberation without reviewing the merger price's fairness or obtaining an independent valuation. A breach of the duty of care subjects the decision to entire fairness review, though many corporations adopt exculpation clauses under statutes like Delaware General Corporation Law Section 102(b)(7) to shield directors from monetary liability for care violations absent bad faith.
Fiduciary Duty (Corporate)
Fiduciary duty in the corporate context refers to the legal obligations that directors, officers, and controlling shareholders owe to the corporation and its shareholders, encompassing primarily the duty of care and the duty of loyalty. These duties require fiduciaries to act in good faith, with the care of a reasonably prudent person, and in the best interest of the corporation rather than for personal benefit. The concept traces to partnership law and was famously articulated by Judge Cardozo in Meinhard v. Salmon, establishing that fiduciaries are held to a standard 'stricter than the morals of the marketplace.' Breach of fiduciary duty is the most common basis for holding directors and officers personally liable in corporate litigation.
Derivative Suit
A derivative suit is a lawsuit brought by a shareholder on behalf of the corporation to enforce a corporate cause of action that the corporation's board has failed or refused to pursue. The shareholder does not sue for personal injury but rather steps into the corporation's shoes, and any recovery flows to the corporation rather than to the individual plaintiff. To bring a derivative suit, the shareholder must typically satisfy the demand requirement by first making a demand on the board to take action or demonstrating that such demand would be futile because a majority of the board is interested or lacks independence. The distinction between derivative and direct claims is critical because derivative suits carry additional procedural requirements including contemporaneous ownership and court approval of settlements.
Shareholder Standing
Shareholder standing refers to the legal requirements a shareholder must satisfy to bring a lawsuit, whether as a direct claim for injury to the shareholder individually or as a derivative claim on behalf of the corporation. For derivative suits, the contemporaneous ownership rule requires that the plaintiff owned shares at the time of the alleged wrongdoing and continues to hold them throughout the litigation. For direct suits, the shareholder must demonstrate a personal injury that is distinct from any injury to the corporation as a whole. The distinction matters because mischaracterizing a derivative claim as direct can result in dismissal, and derivative suits carry procedural hurdles including demand futility and court supervision of settlements.
Merger
A merger is a fundamental corporate transaction in which two or more corporations combine, with one entity (the surviving corporation) absorbing the other (which ceases to exist as a separate legal entity). Mergers typically require approval by the board of directors of each constituent corporation and a vote of the shareholders, usually by a majority or supermajority of outstanding shares. Under the de facto merger doctrine, courts may treat an asset acquisition structured to avoid statutory merger requirements as a merger if the transaction has the economic substance of one, thereby triggering shareholder voting and appraisal rights. In change-of-control mergers, directors face heightened fiduciary duties under frameworks such as Revlon duties and the Unocal test.
Hostile Takeover
A hostile takeover is an acquisition attempt that proceeds without the approval or cooperation of the target company's board of directors, typically through a tender offer directly to shareholders or a proxy contest to replace the incumbent board. The target board may employ defensive measures such as poison pills, staggered boards, or white knight strategies to resist the hostile bid, but these defenses are subject to judicial scrutiny under the Unocal test, which requires the board to show a reasonable belief that a threat to corporate policy existed and that the defensive response was proportionate. If the board determines that a sale of the company is inevitable, Revlon duties require the directors to shift from defending the company to maximizing shareholder value by obtaining the best available price.
Proxy Contest
A proxy contest (or proxy fight) is a mechanism by which a dissident shareholder or group solicits proxy votes from other shareholders to elect their own slate of directors to the board, typically in opposition to the incumbent board's nominees. Proxy contests are governed by federal securities regulations under SEC Rule 14a, which requires extensive disclosure in proxy solicitation materials, and by state corporate law governing the election of directors. They are a key tool of shareholder activism and often accompany hostile takeover attempts, as replacing the board can remove resistance to a proposed acquisition. The incumbent board has the advantage of using corporate funds for solicitation, while dissidents must generally bear their own costs unless they prevail.
Articles of Incorporation
Articles of incorporation (also called a certificate of incorporation or corporate charter) are the foundational document filed with the state to legally form a corporation, establishing its existence as a separate legal entity. The articles typically must include the corporation's name, the number and type of authorized shares, the registered agent and office, and the incorporator's name. The articles may also include optional provisions such as exculpation clauses limiting director liability for duty of care violations, supermajority voting requirements, and restrictions on corporate purposes. As recognized in Dartmouth College v. Woodward, a corporate charter constitutes a contract between the state and the corporation that is protected by the Contract Clause of the Constitution.
Bylaws
Bylaws are the internal governance rules adopted by a corporation that establish procedures for the day-to-day management and operation of the company, covering matters such as the size and structure of the board, meeting notice requirements, quorum rules, officer appointments, and the process for amending the bylaws themselves. Unlike articles of incorporation, bylaws are not filed with the state and can typically be amended by either the board or the shareholders, depending on the jurisdiction and the corporation's charter. Bylaws must be consistent with the articles of incorporation and applicable state law; any bylaw provision that conflicts with the charter or the governing statute is void. They serve as an internal contract among the corporation, its directors, and its shareholders.
Limited Liability
Limited liability is the foundational principle of corporate law providing that shareholders of a corporation are not personally liable for the debts and obligations of the corporation beyond their capital contribution or investment in shares. This protection incentivizes investment by capping the downside risk for shareholders at the amount they paid for their stock, regardless of how large the corporation's liabilities may grow. Limited liability can be forfeited through piercing the corporate veil when courts find that the corporate form has been abused, or when shareholders provide personal guarantees for corporate obligations. The doctrine extends to members of LLCs and limited partners in limited partnerships, though general partners in traditional partnerships do not enjoy this protection.
Partnership
A general partnership is an association of two or more persons who carry on a business as co-owners for profit, formed by agreement (express or implied) without any filing requirement. Under the Uniform Partnership Act and the Revised Uniform Partnership Act, each partner is an agent of the partnership and has the authority to bind the partnership in the ordinary course of business, and all general partners bear joint and several personal liability for the partnership's obligations. Partners owe fiduciary duties to each other, including the duties of loyalty and care, as underscored by Judge Cardozo's famous articulation in Meinhard v. Salmon that partners owe each other the highest duty of good faith. Partnerships are taxed as pass-through entities, with income and losses flowing through to individual partners' tax returns.
Limited Partnership
A limited partnership (LP) is a partnership entity consisting of one or more general partners who manage the business and bear unlimited personal liability, and one or more limited partners who contribute capital and enjoy liability limited to their investment. Limited partnerships must be formed by filing a certificate of limited partnership with the state, unlike general partnerships which can arise informally. Historically, a limited partner who participated in the control of the business could lose limited liability protection, though modern statutes such as the Revised Uniform Limited Partnership Act have substantially relaxed this control rule. Limited partnerships are commonly used in real estate, private equity, and venture capital structures where investors seek limited liability and pass-through taxation while delegating management to a general partner.
LLC
A limited liability company (LLC) is a hybrid business entity that combines the limited liability protection of a corporation with the operational flexibility and pass-through tax treatment of a partnership. Members of an LLC are generally shielded from personal liability for the entity's debts and obligations, and the internal governance is primarily determined by the operating agreement, which functions like a partnership agreement in its flexibility. LLCs can be managed by their members directly (member-managed) or by appointed managers (manager-managed), and unlike corporations, they are not required to observe formalities such as annual meetings or board resolutions. Fiduciary duties in LLCs vary by jurisdiction; some states allow the operating agreement to modify or even eliminate default fiduciary duties, while others treat them as non-waivable.
S-Corporation
An S-corporation is a corporation that has elected special tax status under Subchapter S of the Internal Revenue Code, allowing it to pass corporate income, losses, deductions, and credits through to its shareholders for federal tax purposes, thereby avoiding the double taxation that applies to regular C-corporations. To qualify, the corporation must have no more than 100 shareholders, have only one class of stock, and have only eligible shareholders (generally U.S. citizens and residents, certain trusts, and estates—not partnerships or corporations). From a state corporate law perspective, an S-corporation is governed by the same rules as any other corporation, including fiduciary duties, shareholder voting rights, and the business judgment rule. The S-election is purely a federal tax classification and does not alter the legal structure or governance obligations of the corporation under state law.
Ultra Vires (Corporate)
Ultra vires (Latin for 'beyond the powers') refers to acts taken by a corporation that exceed the scope of authority granted by its articles of incorporation or governing statute. Historically, corporations were formed for specific, limited purposes stated in their charters, and any action beyond those stated purposes was void and unenforceable. As recognized in Dartmouth College v. Woodward, the corporate charter defines the scope of corporate powers as a contractual matter. Modern corporate statutes have largely eliminated the ultra vires doctrine by allowing corporations to be formed for any lawful purpose and by providing that ultra vires cannot be used as a defense in most contract actions, though it may still be raised in a proceeding by shareholders to enjoin unauthorized acts, by the corporation against incumbent or former officers, or by the state attorney general in a dissolution action.
Preemptive Rights
Preemptive rights give existing shareholders the right to purchase a proportional share of any newly issued stock before it is offered to outside investors, thereby protecting shareholders from dilution of their ownership percentage and voting power. Under older corporate statutes, preemptive rights existed as a default rule unless the articles of incorporation opted out; under modern statutes such as the Revised Model Business Corporation Act, preemptive rights exist only if the articles of incorporation affirmatively include them. The scope of preemptive rights can be complex, as they may or may not extend to treasury shares, shares issued for non-cash consideration, or shares issued under employee compensation plans. Preemptive rights are particularly important in closely held corporations where dilution can fundamentally alter the balance of control among a small number of shareholders.
Dividend Rights
Dividend rights are the entitlements of shareholders to receive distributions of corporate profits as declared by the board of directors. The declaration of dividends is generally within the business judgment of the board, and courts rarely compel dividend payments absent a showing of fraud, bad faith, or abuse of discretion, as illustrated in Dodge v. Ford Motor Co., where the Michigan Supreme Court ordered Henry Ford's company to distribute a special dividend to shareholders. Preferred shareholders typically have priority dividend rights specified in the articles of incorporation, which may be cumulative (unpaid dividends accumulate) or non-cumulative. State statutes impose solvency restrictions on dividend payments, generally prohibiting distributions that would render the corporation unable to pay its debts as they come due or that would reduce net assets below the liquidation preference of senior shares.
Insider Trading
Insider trading refers to the purchase or sale of securities by persons who possess material nonpublic information about the issuer, in violation of a duty to disclose or abstain from trading. Under Rule 10b-5 of the Securities Exchange Act of 1934, corporate insiders (directors, officers, and employees) breach their fiduciary duty to shareholders when they trade on material information that has not been publicly disclosed. The misappropriation theory extends liability to outsiders who trade on confidential information obtained through a relationship of trust and confidence, even if they owe no duty directly to the corporation's shareholders. Tippee liability attaches when a person trades on material nonpublic information received from an insider who breached a duty by disclosing the information and received a personal benefit from doing so.
Revlon Duties
Revlon duties arise when a corporation's board decides to sell the company or when a breakup of the corporation becomes inevitable, at which point the directors' fiduciary role shifts from preserving the corporate entity to maximizing the sale price for the benefit of shareholders. Named after the Delaware Supreme Court's decision in Revlon, Inc. v. MacAndrews & Forbes Holdings (1986), this standard requires the board to act as auctioneers charged with obtaining the best price reasonably available, rather than favoring one bidder or using defensive measures to entrench themselves. Revlon duties are triggered in sale-of-control transactions, including cash-out mergers and transactions that result in a change of control, but are not triggered by stock-for-stock mergers where control remains dispersed among public shareholders. A board that fails to conduct a reasonable market check or locks up a deal with a favored bidder without justification faces liability under this heightened standard.
Unocal Test
The Unocal test is an intermediate standard of enhanced judicial review, established in Unocal Corp. v. Mesa Petroleum Co. (1985), applied to evaluate defensive measures adopted by a board of directors in response to a perceived threat to corporate policy or effectiveness, such as a hostile takeover bid. Under the two-pronged test, the board must first demonstrate that it had reasonable grounds to believe a danger to corporate policy and effectiveness existed (the threat prong), and second, that the defensive measure adopted was reasonable in relation to the threat posed (the proportionality prong). This intermediate standard falls between the deferential business judgment rule and the demanding entire fairness standard, reflecting the inherent conflict of interest directors face when their positions are at stake. If the board satisfies both prongs, the business judgment rule applies; if not, the directors bear the burden of proving the entire fairness of their actions.
Entire Fairness Standard
The entire fairness standard is the most exacting standard of judicial review in corporate law, applied when the business judgment rule is rebutted, typically in cases involving self-dealing by directors or transactions with controlling shareholders. Under this standard, the defendant bears the burden of proving that the challenged transaction was entirely fair to the corporation and its minority shareholders, encompassing both fair dealing (the process by which the transaction was negotiated, structured, and approved) and fair price (whether the consideration was adequate in economic terms). The burden may shift to the plaintiff if the transaction was approved by a well-functioning independent committee or by an informed vote of disinterested shareholders, but even then, the court retains jurisdiction to evaluate the transaction's fairness. This standard was applied in cases such as Weinberger v. UOP, Inc. and represents the judicial response to fiduciary conflicts that make deference to the board inappropriate.
Appraisal Rights
Appraisal rights (also called dissenters' rights) are a statutory remedy that entitles shareholders who dissent from certain fundamental corporate transactions—most commonly mergers—to have a court determine and receive the fair value of their shares in cash rather than accept the consideration offered in the transaction. To exercise appraisal rights, the dissenting shareholder must typically follow precise procedural requirements: providing written notice of dissent before the shareholder vote, voting against or abstaining from the transaction, and filing a timely petition for appraisal with the court. The court's fair value determination excludes any element of value arising from the transaction itself, and the valuation methodology may include discounted cash flow analysis, comparable company analysis, and other recognized techniques. Appraisal rights serve as the primary safeguard for minority shareholders who believe they are being cashed out at an inadequate price in a transaction they cannot block.
