Quick reference

Business Law: Sources, Courts and Business Organisations

  • Precedent: ratio decidendi binds lower courts in the same hierarchy; obiter dicta are persuasive only. A higher court may overrule; a later court may distinguish on the facts.

  • Civil standard of proof is the balance of probabilities; criminal standard is beyond reasonable doubt. Civil appeals: High Court to Court of Appeal to Supreme Court; permission to appeal is normally required.

  • Primary legislation = Act of Parliament (Bill passes Commons, Lords, Royal Assent). Delegated legislation = statutory instruments made under a parent Act; ultra vires if beyond the enabling power.

  • A company is a separate legal person (Salomon v Salomon): it owns assets, contracts in its own name, and shareholders have limited liability.

  • Partnership: Partnership Act 1890. Absent contrary agreement, profits and losses are shared equally and partners have unlimited joint (contract) and joint and several (tort) liability.

  • LLP: separate legal personality, members have limited liability; at least two designated members; governed by the LLP Act 2000 and regulations, with mutual agency between members.

  • Agency: agent binds principal where actual authority (express or implied) or apparent/ostensible authority exists. Undisclosed principal may sue and be sued on the contract.

  • Sole trader: unlimited personal liability, no separate legal personality, but full control and simple taxation. Incorporation transfers risk but imposes filing and disclosure duties.

Contract Law: Formation, Terms, Vitiating Factors and Discharge

  • Offer: clear intention to be bound plus specified terms; lapses on rejection, counter-offer, death or reasonable time. Invitation to treat: adverts, displays, auctions, tenders (Fisher v Bell; Partridge v Crittenden).

  • Acceptance must be unqualified and communicated; postal acceptance takes effect on posting where post is contemplated; instantaneous communications (email) take effect on receipt.

  • Consideration must be sufficient but need not be adequate; past consideration is no consideration. Performance of an existing duty owed to a third party can be good consideration (Pao On).

  • Intention to create legal relations: presumed in commercial agreements, rebuttable; presumed absent in social/domestic arrangements, rebuttable on the facts.

  • Terms: representations vs terms by timing, importance and reduction to writing. Conditions are essential; warranties are minor and breach gives damages only; innominate terms are classified by effect of breach.

  • Exclusion clauses must be incorporated (signature, notice, course of dealing) and construed contra proferentem; UCTA 1976 and CRA 2015 restrict liability for death/personal injury and unreasonable terms.

  • Misrepresentation: false statement of fact inducing the contract. Types: fraudulent, negligent (s.2(1) Misrepresentation Act 1967), innocent. Remedies: rescission and/or damages; bars to rescission include affirmation, lapse of time and third-party rights.

  • Frustration discharges the contract automatically on an unforeseen event destroying the purpose; Law Reform (Frustrated Contracts) Act 1943 allows recovery of money paid and just allowance for work done.

  • Damages: expectation measure (put claimant in position as if performed), remoteness under Hadley v Baxendale (arising naturally or in contemplation), and mitigation duty. Penalty clauses unenforceable; liquidated damages genuine pre-estimate enforceable.

Company Law: Formation, Capital, Directors and Shareholders

  • Formation: registration at Companies House requires memorandum, articles, statement of capital and initial shareholdings, and statement of compliance. Certificate of incorporation is conclusive evidence.

  • Directors' general duties (CA 2006 ss.171-177): act within powers; promote success of the company; exercise independent judgment; reasonable care, skill and diligence; avoid conflicts; no benefits from third parties; declare interest in proposed transactions.

  • Shareholder remedies: derivative claim (s.260), unfair prejudice petition (s.994), just and equitable winding up (s.122(1)(g) Insolvency Act 1986).

  • Capital maintenance: dividends only from distributable profits; reduction of capital requires special resolution and court or solvency statement procedure; financial assistance rules apply to private companies subject to solvency statement.

  • Share issues: directors need authority (s.551) and pre-emption rights apply to equity securities (s.561) unless disapplied by special resolution or articles.

  • Company decision-making: members' ordinary resolution = simple majority; special resolution = 75%. Written resolutions available to private companies; public companies require meetings.

  • Directors' conflicts: s.175 duty not to have conflicts unless authorised by independent directors or members; s.177 declaration of interest in existing transaction to the board.

  • Audit and filing: small companies may be exempt from audit; annual accounts and confirmation statement filed at Companies House; late filing penalties apply.

Insolvency and Employment Law: Procedures, Priorities and Employment Rights

  • Insolvency tests: cash-flow (unable to pay debts as they fall due) and balance-sheet (liabilities exceed assets). Statutory demand £750 unpaid for 21 days can ground a winding-up petition.

  • Administration: moratorium, statutory purpose (rescue company, achieve better result than winding up, realise property), administrator must act in interests of creditors as a whole; 8-week pre-pack rules.

  • CVA: company voluntary arrangement, requires 75% by value of creditors voting (excluding connected persons) and simple majority in number; binds unsecured creditors.

  • Liquidation: members' voluntary (solvency declaration), creditors' voluntary (insolvent), compulsory (court order). Order of distribution: fixed charge creditors, expenses, preferential creditors, floating charge, unsecured, members.

  • Wrongful trading (s.214): director liable where, before winding up, they knew or ought to have known insolvency and failed to take every step to minimise loss. Fraudulent trading (s.213) requires intent to defraud.

  • Employment status: employee (mutual obligation, personal service, control) vs worker (personal service, no mutual obligation) vs self-employed. Only employees get unfair dismissal and redundancy rights.

  • Unfair dismissal: qualifying period normally 2 years; reason must be one of the statutory fair reasons; procedural fairness (ACAS Code); remedy: reinstatement, re-engagement or compensation.

  • Redundancy: genuine redundancy (closure or diminished need for work), fair selection, consultation (20+ employees: 30/45 days), statutory redundancy pay based on age, weekly pay cap and length of service.

  • Discrimination: Equality Act 2010 protected characteristics; direct, indirect, harassment and victimisation; objective justification for indirect discrimination and age; burden shifts to employer to prove no discrimination.
