Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

The examinable core. “Explain the classification of companies” was set in January 2026 (both papers) and June 2025. Use the classification chart in section 4 with the section of the Companies Act, 2013 against each class. Two comparisons recur: public versus private company, and partnership versus company.

1. Meaning

Section 2(20) of the Companies Act, 2013 defines a company as “a company incorporated under this Act or under any previous company law.” The textbook definition is Lord Justice Lindley’s: an association of many persons who contribute money or money’s worth to a common stock and employ it in some trade or business, and who share the profit or loss arising from it. Chief Justice Marshall called a corporation “an artificial being, invisible, intangible, and existing only in contemplation of law.”

2. Features

  1. Incorporated association: comes into existence only on registration and the issue of a certificate of incorporation.
  2. Separate legal entity: distinct from its members (Salomon v. Salomon & Co. Ltd., House of Lords, 1897). It can own property, sue and be sued in its own name.
  3. Limited liability of members, to the amount unpaid on their shares or the amount guaranteed.
  4. Perpetual succession: members may come and go, the company continues.
  5. Transferability of shares: freely transferable in a public company (section 44 treats shares as movable property), restricted in a private company.
  6. Common seal: optional since the Companies (Amendment) Act, 2015; documents may be signed by authorised persons.
  7. Separation of ownership and management: shareholders own, the board of directors manages.
  8. Artificial legal person acting through human agents.

3. Merits and demerits

Merits: large capital from many investors; limited liability encourages investment; stability through perpetual succession; liquidity of investment through transferable shares; professional management; economies of large scale; public confidence because accounts are audited and published; scope for research and expansion.

Demerits: difficult and costly formation; heavy legal compliance (annual returns, audit, board meetings, filings with the Registrar); lack of secrecy; delay in decisions; separation of ownership and control, which lets managers act in their own interest; oligarchic management by a small group of directors; speculation in shares; and possible concentration of economic power.

How this is examined

June 2025 (100 marks) asked the difference between a public and a private company; February 2025 asked the difference between a partnership firm and a joint stock company.
