exemption clauses Flashcards
the parol evidence rule
the rule that where a written contract document purports to record all the terms of the parties agreement, no evidence can be adduced to vary / contradict it
parol evidence rule applied
henderson v aruthur
-> a tenant could not adduce evidence of an alleged prior agreement to accept IOU’s for rent when the deed of lease required rent to be paid in cash
exceptions to the rule
- the contract is partly in writing and partly oral
- the oral promise can be treated as giving a rise to a collateral contract
tensions underpinning rule + exceptions
- law is not very coherent here
What is the Heilbut case’s significance for the parol evidence rule and collateral contracts?
Parol Evidence Rule: Written contracts can’t usually be altered by external evidence
Collateral Contracts: Separate oral agreements alongside a main contract.
Rare and viewed skeptically by courts.
Must be proven with clear, strict evidence.
Key Quotes:
Viscount Haldane: Courts won’t assume collateral contracts without clear language.
Lord Moulton: Collateral contracts must be strictly proven and are rare, as modifying the main contract directly is more usual.
effect of entire agreement clauses
- will prevent collateral agreements arising out of oral pre-contractual assurances
-> however, they do not prevent adducing extrinsic evidence going to interpretation
-> neither does it prevent claims in misrepresentation unless the wording excludes this in clear terms
“no oral modification” clauses
- traditional view is that parties cannot give up normal power that everyone has to enter into an oral contract by agreeing that no amendment can be made to the written contract unless it is made in writing
advantages of NOM clauses
Certainty: Ensures all parties agree formally to changes, avoiding misunderstandings
Protection: Prevents one party from unilaterally claiming a change was agreed orally
Business Efficiency: Encourages professionalism and proper documentation in contractual relationships
MWB Business Exchange v Rock Advertising (2018):
The UK Supreme Court upheld the NOM clause, emphasizing its purpose to promote certainty and avoid informal variations that could lead to disputes.
However, the court noted that NOM clauses can still be overridden by express agreement or clear conduct, but this requires strong evidence.
exemption clause
an exemption clause is a contract term that relieves a party of some/all of their liability, in the event of their breach of contract, committing a tort or breaching some other duty
controversiality around exemption clauses
- they can defeat the parties expectations; if you pay money for an item you pay expect to be compensated if the product is not up to standard
- they can disincentivise taking care, “moral hazard”
- in extreme, can empty a party’s duties of all content
- unfair surprise, the existence of exemption clauses is often unlikely to be appreciated by consumers and small businesses
in defence of exemption clauses
- help define the parties duties to one another
- valuable way of allocating risk between the parties, often linked to insurance considerations
- exclusion and limitation-of-liability clauses are common in properly negotiated contracts between well advised commercial entities of equal bargaining power
- not all unfair terms are exemption clauses
common-law control of exemption clauses
- rules on incorporation of unsigned notices
- contra preferentem
- strict interpretation of exemption clauses
problems with common-law control mechanisms
- applied ‘one-size-fits-all’ manner; judge made law should be of universal application
- did not prevent determined parties from introducing and relying on unfair terms and making sure exemption clauses were drafted to meet the restrictive rules of interpretation developed in case law
- some of the rules were limited to targeting exemption clauses
contra preferentem
any ambiguity is to be resolved against the party who introduced the clause
