So an “exclusion clause” is any clause that seeks to avoid liability e.g. Some companies have a contractual clause in their contracts stating “We are not liable for any damage caused whilst you are on our premises, its at your own risk”.
Doctrine of Privity- means that only the 2 parties to a contract can enforce the contract. Third parties can not enforce the contract. So for example if I have a contract to borrow money from a bank, only me and the bank can enforce the contract. My wife (a third party) does not have any rights on my contract as it is “private/privity”.
