Final answer:
The assignment of contract rights alters the duty of the obligor, as it transfers benefits from one party to another while maintaining contractual obligations. It is critical for the legal system to enforce these obligations to ensure economic activity and fair transactions.
Step-by-step explanation:
Any assignment of contract rights will change an obligor's duty to some extent. When an individual or entity assigns their rights under a contract, they are transferring their benefits from the agreement to another party. Contractual rights and duties are the foundation for transactions in a society with strong property rights and a legal system to uphold agreements, ensuring that parties to a contract have recourse in the event of noncompliance. For example, an employment contract between a surgeon and a patient entails a commitment from the patient to compensate the surgeon for their services, with legal consequences if this contractual obligation is not met. The legal system enforces these contracts, which is essential for economic growth and the smooth operation of business activities. An assignment can shift expectations and responsibilities, but it should not impair obligation of contracts nor should it abridge privileges or immunities, or deny due process and equal protection of the laws.
