1. Introduction-

Carlill v Carbolic Smoke Ball Co. (1893) is a leading English case that laid down important principles regarding general offer, unilateral contract, acceptance by performance, and intention to create legal relations.

It established that advertisements can amount to valid offers if intention is clear and the terms are definite.

2. Facts of the Case-

→The defendant company manufactured a product called "Carbolic Smoke Ball", claimed to prevent influenza.

→They issued an advertisement in newspapers stating:

"£100 Reward will be paid to any person who contracts Influenza after using the Carbolic Smoke Ball three times daily for two weeks as directed."

→To show sincerity, they deposited £1000 in the Alliance Bank.

→Mrs. Carlill purchased the smoke ball and used it as per the instructions.

→Still, she contracted influenza.

→She claimed the reward of £100, but the company refused to pay.

3.The Promise (Advertisement)-

4. ISSUES-

→Whether the advertisement amounts to offer or mere invitation to offer?

→Whether acceptance requires communication?

→Whether there was valid consideration?

→Whether intention to create legal relations existed?

→Whether contract with the whole world is possible?

5. ARGUMENTs-

PLAINTIFF (MRS. CARLILL)	DEFENDANT (COMPANY)
→The advertisement is a general offer to the public. →The terms are clear, definite and certain. →Acceptance is by performance (i.e., using the smoke ball as directed). →Consideration exists: -She purchased the product. -She used it as directed, causing inconvenience. →Deposit of £1000 shows serious intention to create legal relations.	→The advertisement is a mere puff or sales gimmick. →No intention to create legal relations. →Acceptance not communicated. Contract with the whole world is impossible. →No valid consideration.

6. JUDGMENT (COURT OF APPEAL)-

The Court ruled in favour of Mrs. Carlill and held the company liable to pay £100.

Key Observations:

(A) Advertisement = Offer: The advertisement was a clear, definite and serious offer to the public, not a mere invitation to offer.

(B) Intention to Create Legal Relations: Deposit of £1000 in bank was strong evidence of genuine intention.

(C) Acceptance by Performance: In unilateral contracts, acceptance is complete by performance of the stipulated condition. No communication of acceptance is required.

(D) Consideration: Plaintiff bought and used the smoke ball, causing inconvenience. The company gained benefit through sale and publicity. Hence, valid consideration existed.

(E) Contract with the World: An offer can be made to the world at large. Contract arises only with those who perform the conditions.

Final Decision: Contract was valid and binding. Company was liable to pay £100.

7. LEGAL PRINCIPLES LAID DOWN-

General Offer:

An offer can be made to the public at large.

Unilateral Contract:

One party makes a promise and the other accepts by performing the stipulated condition.

Acceptance by Conduct:

 Acceptance can be by act or performance; communication of acceptance is not necessary in unilateral contracts.

Intention to Create Legal Relations:

 Intention is the foundation of any contract. It must be real, clear and provable.

Advertisement as Offer:

An advertisement can amount to an offer if it is clear, definite, concrete and made with a serious intention.

9.IMPORTANT OBSERVATIONS (BY BOWEN LJ)-
