The article discusses the difference between contractual and non-contractual liability in legal systems. It explains that when harm is caused due to a breach of contract, the party at fault is liable for damages. However, if harm occurs without a contract or is unrelated to the contract, non-contractual liability applies. Some experts believe these are two separate legal systems, while others see them as part of a single system aimed at compensating for losses. The research shows that despite having a contract, the victim can still seek compensation under non-contractual liability rules.
