Chapter six of the Principles of European Contract Law on 'content and effects' clarifies any elements of the contract where there is potential for dispute.
Among the issues included are:
- statements that form part of the contract - even if not written into the contract itself
- implied obligations
- how price, quantity, quality and ending the contract are dealt with if not included in the actual contract terms
The emphasis is on reasonable behaviour by both sides in dealing with issues where there is any doubt or confusion.
