Contracts that depend on the unique skills of the contracting party cannot be assigned without consent.
Professor Notes

In Mackay v. E. R. du Pont de Nemours & Co., the court addressed the issue of whether a contract that relies on unique personal skills can be assigned to a third party. The court emphasized the importance of maintaining the integrity of contracts that are inherently personal in nature. This case serves as an important precedent regarding the non-assignability of contracts where the original party's personal skills and abilities are vital to the contract's performance. Professors might discuss the implications for contractual relationships and the necessity of consent in assignments. Additionally, they may highlight how this ruling melds with the broader principles of contract law concerning personal service agreements.
