194 F.2d 242 (3d Cir. 1940)
Mackay v. E.
Can a contract that fundamentally involves personal skills or services be assigned to a third party?
Contracts that are dependent on personal skills or performances are generally non-assignable unless all parties to the contract agree to the assignment.
The court held that the assignment of the contractual rights was invalid due to the personal nature of the services required under the contract. The contract's fulfillment was contingent on the unique skills and abilities of the original contracting party, making it non-assignable without the consent of the party receiving the services.
The Mackay case is critical for law students as it reinforces the limits on the assignability of certain contracts, particularly those dependent on personal performance. It underscores the principle that not all contracts are freely assignable and elucidates the necessity of parties' consent in the assignment of such personal service contracts. This case is particularly relevant for fields involving personal services, consultancy, and other contracts where unique skills or attributes are a significant factor.
