Q

SUBJECTIVE/RELATIVE IMPOSSIBILITY:

A

1) Impossibility insufficient to render performance impossible

2) Contract is valid

Q

FACTUAL AND PRACTICAL IMPOSSIBILITY

A

1) Performance is extremely:
2) Difficult
3) Dangerous OR
4) Costly (Economic impossibility).
5) TEST: Commercial reasonableness

Q

OBJECTIVE/ABSOLUTE IMPOSSIBILITY:

A

1) The impossibility is so severe that nobody
could render performance.

2) E.g. Where the subject matter of the contract is destroyed

Q

LEGAL IMPOSSIBILITY

A

1) Performance should be lawful or legal for a contract to be valid.

2) Legal impossibility: Contract is void

3) Wilson v Smith

4) If impossibility flows from illegality then the the contact is void for illegality

Q

In the case of voidness due to illegality:

A

1) Claims for restitution are governed by the par delictum rule

2) Which bars such claims in certain cases where the parties are tainted by the illegality.

3) This rule does not apply in cases of voidness due to impossibility

Q

INITIAL IMPOSSIBILITY:

A

1) Impossible before conclusion of
contract: Renders contract:

Q

1) Impossibility after conclusion, obligations
created, but may be terminated due to
impossibility.

Q

Supervening Example:

A

1) A and B enter is to a lease agreement but later the subject of the lease becomes destroyed, then obligations terminate due to impossibility

2) Fault: Where A deliberately destroyed the
property – breach of contract

Q

Warranties:

A

1) A term in a contract which extends the liability of a party further than is ordinary.

2) Therefore warranty could impose obligations even if such obligations are impossible to perform.

3) Action instituted on basis of breach of warranty

Q

CONSEQUENCES OF IMPOSSIBILITY:

A

1) No obligation arises if performance is
objectively impossible.

2) There cannot be a claim for performance or contractual damages.

3) Prior part performance must be returned

Q

Partial impossibility is possible?

A

16
Q

Stansfeld v Khun

A

1) Where performance is not divisible, the position is more complex.

2) Depending on the circumstances, the contract could be:
2.1) invalid in its entirety, or
2.2) there could be a proportional reduction of the counter-performance

17
Q

CERTAINTY GR:

A

1) Uncertainty about what has to
be performed prevents the creation of
obligations

2) Certainty includes the ability to be rendered certain (ascertainable), generally through an appropriate mechanism described in the contract itself

18
Q

CONTRACT TO CREAT ANOTHER
CONTRACT

A

1) Can be invalid, unless the parties have agreed to the terms of the
contract to be made

19
Q

Some examples of Contract to create another contract:

A

1) Options & preference contracts.
2) Agreement to negotiate later in good faith is not void for uncertainty
3) Memorandum of Understanding (MOU).

20
Q

Agreement to negotiate later in good faith is not void for uncertainty.
▪ Requires a deadlock-breaking mechanism in order to be valid

A

1) Southernport Development (Pty) Ltd v Transnet Ltd – Arbitration for final determination if negotiations fail.

2) Makate v Vodacom Ltd – Call Me case – CEO left as the final decision maker as to a fair price

21
Q

VAGUE LANGUAGE

A

1) Whilst courts will generally try to give effect to a contract rather than strike it down,

2) Vague language can render a contract void

22
Q

CONTRACTS OF AN INDEFINATE PERIOD

A

1) Parties may sometimes enter into contracts for an indefinite period.

2) Courts generally give effect to these
contracts despite the uncertainty they
create.

3) Courts will seek guidance from the actual
or presumed intention of the parties in
giving effect to the contract.

23
Q

Validity of CONTRACTS OF AN INDEFINATE PERIOD

A

1) Such contracts are valid and enforceable,
and not automatically void for uncertainty.

2) Contract in force until termination by
reasonable notice.

3) Contract force until a reasonable
period lapses.

4) Contract will endure forever, if
possible.

24
Q

The mechanism must function independently from the intention of the parties, although a party can be
involved in the mechanism:

A

1) Mechanism in the contract. E.g.: Escalation clause: Increase in rental amount 10% after every 6 months.

2) External mechanism or standard. E.g.: Inflation.

25
Other Mechanisms in Contracts
1) Reasonable price is generally, but not always deemed uncertain. 2) By a third party: 3P may determine performance, as long as they are identifiable and they determine the performance objectively and reasonably. 3) By determination of one of the parties: Not valid if determining one’s own performance.
26
CONSEQUENCES OF LACK OF CERTAINTY
1) An obligation which is uncertain is invalid. 2) If this is the sole or main obligation, then the contract is void. 3) If the obligation can be separated then the remaining obligations can be enforced (Severability of obligations).
