Rules relating to construction and interpretation of contracts
The assumption that both parties have understood accurately the terms within a contract.
A dispute will arise when there is a term that is argued to have different meanings from the different parties.
For exclusion clauses, these will usually put someone in the contract into a stronger bargaining position.
Most people do not read the terms unless there is a breach. Only at this point will terms of the contract be interpreted (contra proferentem rule)
