Contract Formation, Terms, and Defenses

  • Common-law formation requires offer, acceptance, consideration, capacity, and legality; UCC Article 2 sales of goods require only offer, acceptance, and consideration.

  • Mailbox rule: acceptance is effective on dispatch for ordinary contracts; an option is irrevocable only with consideration or a UCC 2-205 firm offer (merchant, signed writing, three months maximum).

  • UCC 2-207: a definite and seasonable expression of acceptance forms a contract even on different terms; between merchants, additional terms enter unless they materially alter the deal, are objected to, or the offer limited acceptance.

  • Statute of Frauds categories requiring a signed writing: marriage, one year or more, land, executor promises, suretyship, and goods of $500 or more; signature of the party to be charged is required.

  • Parol evidence rule excludes prior or contemporaneous agreements contradicting a fully integrated writing; exceptions include ambiguity, fraud, condition precedent, and course of performance or dealing.

  • Defenses to enforcement: fraud in the factum versus fraud in the inducement, duress, undue influence, mutual mistake, unconscionability, illegality, incapacity, and Statute of Frauds.

  • Unconscionability generally requires procedural unfairness (surprise, unequal bargaining power) plus substantive oppression (excessive price, one-sided terms) at the time of contracting.

  • Liquidated damages are enforceable when damages were difficult to estimate at contracting and the stipulated sum is a reasonable forecast; otherwise the clause is an unenforceable penalty.

  • Anticipatory repudiation must be clear and unequivocal; the non-breaching party may treat it as breach, suspend performance, or await performance for a commercially reasonable time.

Business Organizations and Corporate Governance

  • Sole proprietorships and general partnerships impose unlimited personal liability; corporations and LLCs shield owners absent veil piercing.

  • UPA default rules: equal profit sharing, majority vote on ordinary matters, unanimous consent for fundamental changes, and joint and several liability for torts.

  • Limited partners lose limited liability if they participate in control; LLC members are shielded and a charging order is often the exclusive remedy of a member's personal creditor.

  • Business judgment rule presumes directors acted in good faith, on an informed basis, and without conflicting interest; the plaintiff bears the burden of rebutting the presumption.

  • Fiduciary duties are care and loyalty; loyalty covers self-dealing, corporate opportunity, and insider trading, while duty of care claims are exculpable in Delaware but loyalty claims are not.

  • Veil piercing factors: alter ego, commingling of funds, undercapitalization, failure to observe formalities, and fraud or injustice.

  • Derivative suits require demand on the board or futility; demand is excused where a majority of directors is conflicted or demand would be wrongfully refused.

  • Section 16(b) recovers short-swing profits by insiders within six months; Rule 10b-5 requires a material misstatement or omission, scienter, reliance, and damages.

  • S corporation limits: 100 or fewer shareholders, one class of stock, eligible individuals only; C corporations bear entity-level tax plus shareholder dividend tax.

Sales of Goods and Commercial Transactions

  • UCC Article 2 governs transactions in goods; mixed goods-and-services contracts use the predominant purpose test to choose between Article 2 and common law.

  • Merchant status triggers UCC 2-205 firm offers, the merchant additional-terms rule of 2-207(2), and the implied warranty of merchantability.

  • Perfect tender rule (2-601) lets a buyer reject nonconforming goods in a single-delivery contract; installment contracts require substantial impairment of the whole (2-612).

  • Risk of loss: shipment contracts pass risk to the buyer when goods are delivered to the carrier; destination contracts pass on tender at destination; FOB, CIF, and CFR allocate accordingly.

  • Implied warranties are merchantability (fit for ordinary purpose), fitness for particular purpose (seller knows buyer's purpose and buyer relies), and title or non-infringement.

  • Disclaimer rules: merchantability disclaimers must mention merchantability and be conspicuous; fitness disclaimers must be in writing and conspicuous; 'as is' disclaims implied warranties in most states.

  • Cure (2-508): the seller may cure within the contract time, or within a reasonable time after rejection if the seller had reasonable grounds to believe the tender would be acceptable.

  • Buyer remedies: cover damages (2-712), market-price damages (2-713), incidental and consequential damages; seller remedies include resale, lost profits, and the contract price.

  • Adequate assurance (2-609) may be demanded on reasonable grounds for insecurity; failure to provide it within 30 days operates as repudiation.

Agency, Employment, and Labor Relations

  • Agency arises by express appointment, implication, estoppel (apparent authority), or ratification; the agent owes duties of loyalty, obedience, care, and accounting.

  • Apparent authority requires a manifestation by the principal to a third party that reasonably induces reliance; it cannot be manufactured by the agent alone.

  • Respondeat superior makes a principal liable for an employee's torts within the scope of employment; intentional torts fall outside scope unless foreseeable or job-related.

  • Employee versus independent contractor tests: common-law right to control, FLSA economic reality factors, and the ABC test used in some states, which presumes employee status.

  • Employment at will permits termination for any lawful reason; exceptions are public policy, implied contract, and, in some jurisdictions, the covenant of good faith.

  • FLSA: minimum wage and overtime at 1.5 times the regular rate beyond 40 hours weekly; white-collar exemptions require a salary basis plus duties tests.

  • NLRA Section 7 protects concerted activity; Section 8(a)(1)-(5) list employer unfair labor practices including interference, discrimination, and refusal to bargain.

  • Title VII: disparate treatment uses McDonnell Douglas burden-shifting; disparate impact uses the Griggs test; retaliation requires protected activity, adverse action, and causation.

  • WARN Act requires 60 days' notice for qualifying mass layoffs and plant closings; workers' compensation is generally the exclusive remedy for workplace injury.

Quick reference

Torts, Product Liability, and Consumer Protection

  • Negligence elements: duty, breach, actual cause ('but for'), proximate cause (foreseeability), and damages; res ipsa loquitur permits an inference from exclusive control and ordinary causation.

  • Strict product liability: a defective condition unreasonably dangerous, existing when the product left the seller's control, causing physical harm; negligence need not be shown.

  • Defect theories are manufacturing defect, design defect (consumer expectation or risk-utility test), and failure to warn, including foreseeable misuse.

  • Product liability defenses: assumption of risk, misuse, comparative fault, substantial modification, federal preemption, and statutes of repose.

  • Defamation elements: defamatory statement of fact, publication to a third party, fault, and damages; public officials and public figures must prove actual malice.

  • FTC Act Section 5 prohibits unfair or deceptive acts or practices; deception requires a material representation likely to mislead a reasonable consumer.

  • State UDAP statutes commonly add private rights of action, statutory or multiple damages, and fee shifting, and are often broader than the FTC standard.

  • Class certification requires numerosity, commonality, typicality, and adequacy, plus predominance and superiority for Rule 23(b)(3) damages classes.

  • Fraudulent misrepresentation elements: material false statement of fact, scienter, intent to induce reliance, justifiable reliance, and resulting damages.

Quick reference

Negotiable Instruments and Secured Transactions

  • Negotiability requires a signed writing, an unconditional promise or order to pay a fixed sum, payment on demand or at a definite time, payable to bearer or order, and no other undertaking.

  • Holder in due course status requires taking for value, in good faith, and without notice of dishonor, defenses, or claims; an HDC takes free of personal defenses but not real defenses.

  • Real defenses include infancy, duress, fraud in the factum, illegality, bankruptcy discharge, material alteration, and forgery.

  • Article 9 attachment requires value given, debtor rights in the collateral, and an authenticated security agreement describing the collateral.

  • Perfection methods: filing a UCC-1 financing statement, possession, control (deposit and investment accounts), automatic PMSI in consumer goods, and certificate-of-title notation.

  • Priority generally follows first to file or perfect; a purchase-money security interest in goods perfected within 20 days after the debtor receives possession defeats an earlier conflicting interest.

  • Security interests in real property are mortgages governed by real estate law, not Article 9; Article 9 covers personal property and fixtures.

  • Repossession must avoid breach of the peace; disposition must be commercially reasonable; strict foreclosure requires notice and consent; deficiency judgments require proper notice.

  • Indorsement types: blank (bearer), special (names a payee), restrictive ('for deposit only'), and qualified ('without recourse') disclaiming indorser liability.

Quick reference

Regulatory Compliance and Antitrust

  • Sherman Act Section 1 requires a contract, combination, or conspiracy in restraint of trade; horizontal price fixing, bid rigging, and market allocation are per se unlawful.

  • Sherman Act Section 2 elements: monopoly power in the relevant market plus willful acquisition or maintenance of that power, as distinguished from growth by superior skill.

  • Clayton Act Section 7 bars mergers whose effect may substantially lessen competition; HSR premerger notification is required above statutory size-of-transaction and size-of-person thresholds.

  • HHI equals the sum of the squares of market shares; the 2023 U.S. merger guidelines treat roughly 1,800 and above as highly concentrated and a change above 100 as presumptively unlawful.

  • Rule of reason analysis: define the relevant market, establish market power, show anticompetitive effects, then weigh procompetitive justifications and less restrictive alternatives.

  • Robinson-Patman Act prohibits price discrimination that injures competition; defenses are cost justification and meeting competition in good faith.

  • FCPA prohibits bribery of foreign officials and requires accurate books and records and internal controls; liability extends to third-party intermediaries.

  • GDPR requires a lawful basis for processing, honors data-subject rights, mandates breach notification within 72 hours, and permits fines up to 4% of global annual turnover.

  • Sarbanes-Oxley requires CEO and CFO certifications, internal control reporting, auditor independence, and whistleblower protections.

Intellectual Property and Technology Licensing

  • Copyright protects original expression fixed in a tangible medium; duration is life plus 70 years for individuals and 95 years from publication for works made for hire.

  • Fair use factors: purpose and character of the use, nature of the copyrighted work, amount used, and effect on the potential market for the work.

  • Patentability requires utility, novelty, non-obviousness, and enablement; utility and plant patents last 20 years from filing, design patents 15 years from grant.

  • The America Invents Act moved the United States to first-inventor-to-file, with a one-year grace period covering the inventor's own disclosures.

  • Trademark distinctiveness spectrum: generic (unprotectable), descriptive (secondary meaning required), suggestive, arbitrary, and fanciful (strongest).

  • Trade secret protection requires reasonable secrecy measures and independent economic value; the Defend Trade Secrets Act creates a federal civil cause of action.

  • License scope defines exclusive versus non-exclusive rights, territory, field of use, and term; generally only an exclusive licensee has standing to sue infringers.

  • Copyleft licenses such as GPL require derivative works to be licensed on the same terms; permissive licenses such as MIT and Apache 2.0 allow proprietary derivatives with attribution.

  • DMCA Section 512 gives intermediaries a notice-and-takedown safe harbor; Section 1201 prohibits circumvention of technological protection measures.

Quick reference

Bankruptcy, Insolvency, and Creditors' Rights

  • Chapter 7 liquidation applies the means test, exempts property, and discharges debts; the trustee liquidates non-exempt assets and distributes under Section 726.

  • Chapter 11 reorganization features the automatic stay, the debtor in possession, 120-day exclusivity, and confirmation by class acceptance or cramdown.

  • Chapter 13 is for individual wage earners with regular income and capped secured and unsecured debt, funded through a three-to-five-year plan.

  • Automatic stay (Section 362) halts collection, litigation, and lien enforcement; relief requires a motion, and willful stay violations can yield actual and punitive damages.

  • Preference (Section 547): a transfer to a creditor within 90 days (one year for insiders), for antecedent debt, while insolvent, enabling greater recovery than in a Chapter 7.

  • Section 507 priority: administrative expenses, gap claims, wages up to the statutory cap, employee benefits, and taxes rank ahead of general unsecured claims.

  • Nondischargeable debts (Section 523) include fraud, student loans absent undue hardship, domestic support, willful and malicious injury, and certain taxes.

  • Strong-arm power (Section 544) lets the trustee avoid unperfected security interests; fraudulent transfers under Section 548 and state law are also avoidable.

  • Chapter 11 confirmation requires the best-interests test, feasibility, and absolute priority unless each impaired class accepts the plan.

Quick reference

Ethics and Professional Responsibility

  • Model Rule 1.1 requires competent representation: the legal knowledge, skill, thoroughness, and preparation reasonably necessary for the matter.

  • Confidentiality (Rule 1.6) bars revealing information relating to the representation absent informed consent or an exception such as preventing reasonably certain death or substantial bodily harm.

  • Current-client conflicts (Rule 1.7) require informed consent where the representation is directly adverse or materially limited; some conflicts are nonconsentable.

  • Former-client conflicts (Rule 1.9) bar adverse representation in the same or a substantially related matter where confidential information is material.

  • Rule 1.15 requires client funds to be held in a separate trust account; commingling is prohibited and disputed funds must be kept separate until resolved.

  • Candor to the tribunal (Rule 3.3) requires disclosure of adverse controlling authority and forbids offering false evidence.

  • Rule 4.2 bars communication with a represented person about the subject of the representation absent counsel's consent or authorization by law.

  • Rule 1.13 governs organizational clients: report misconduct up the ladder and, if warranted, to the highest authority or outside the organization.

  • Fee agreements must be reasonable under Rule 1.5; contingent fees are barred in criminal matters and restricted in domestic relations cases.

International Trade and Cross-Border Transactions

  • CISG applies to international sales of goods between parties whose places of business are in different Contracting States; consumer sales and listed transactions are excluded.

  • CISG has no consideration requirement and no parol evidence rule; intent is determined from statements and conduct and all relevant circumstances (Articles 8 and 11).

  • CISG remedies: avoidance for fundamental breach, damages measured by foreseeable loss (Article 74), and mitigation of loss (Article 77).

  • Incoterms 2020 allocate risk and cost: EXW (buyer at seller's premises), FOB and CIF (risk passes on shipment), DAP and DDP (seller bears delivery and, for DDP, import duties).

  • UCP 600 governs documentary letters of credit: banks deal in documents rather than goods and require strict compliance with the credit terms.

  • Export controls: EAR covers dual-use items and deemed exports, ITAR covers defense articles, and OFAC administers sanctions; violations carry civil and criminal penalties.

  • WTO principles: most-favored-nation treatment, national treatment, and tariff bindings, enforced through the Dispute Settlement Understanding.

  • Trade remedies: antidumping duties for below-fair-value sales, countervailing duties for subsidies, and safeguards for unforeseen import surges.

  • Cross-border dispute resolution: choice-of-law rules such as Rome I, New York Convention enforcement of arbitral awards, and ICSID for investor-state arbitration.
