Attorney Mail Solicitation Ban
Stella Shapiro, an attorney, mailed brochures to recent accident victims within thirty days of their injuries. The state bar enforced its rule against such mailings. The court upheld the ban because the state possessed a substantial interest in protecting the victims' privacy and the bar's reputation during their period of vulnerability.
Frequently Asked2
What makes a governmental interest substantial enough to restrict commercial speech?+
A governmental interest is substantial when it concerns the protection of privacy, the reputation of a profession, or consumer welfare in a manner that is unrelated to the suppression of expression. The interest must be real and the restriction must directly advance it with a reasonable fit.
Supporting sources
How does the substantial-interest test in contracts differ from the governmental-interest test in commercial-speech cases?+
The contract test focuses on whether the obligee bargained for personal performance by a particular promisor. The commercial-speech test focuses on whether the government has a significant non-speech-related objective that the restriction directly advances. The two inquiries serve entirely different doctrinal purposes.

Delegated Network Monitoring
Midnight Satellite contracted with Delta Fiber for dedicated fiber installation and 24/7 monitoring by Delta Fiber's own elite team to guarantee 99.9 percent uptime. Delta Fiber delegated the monitoring to Highland Telecom without notice. Midnight Satellite had a substantial interest in Delta Fiber's personal performance because it had specifically negotiated for the internal team's reputation and direct accountability.
Personal Performance Promise
Sophia Singh hired Serena Soto to design and install custom cabinetry in her home because Soto had a distinctive style and reputation for precision. Soto attempted to delegate the work to another carpenter. Singh possessed a substantial interest in Soto's own performance, so the delegation was improper.
Distribution Agreement Delegation
Nexxus Products granted Best a distribution agreement requiring Best to sell and promote Nexxus hair-care products. Best assigned its rights and delegated its duties to Sally Beauty, a competitor of Nexxus. Nexxus had a substantial interest in Best's own performance of the promotion and sales duties, rendering the delegation ineffective.
Sally Beauty Co. v. Nexxus Products Co.801 F.2d 1001 (1986)
Frequently Asked2
When does an obligee have a substantial interest preventing delegation under UCC § 2-210?+
An obligee has a substantial interest when the contract terms or negotiations show that the obligee specifically bargained for the original promisor's personal performance or control. The interest exists even if the contract does not expressly prohibit delegation. Courts examine whether the identity of the performer was a material term of the bargain.
Supporting sources
Does a substantial interest in contract performance survive an assumption agreement by the delegatee?+
No. An assumption agreement between the delegator and delegatee does not discharge the delegator's liability unless the obligee expressly agrees to the release. The obligee's substantial interest in the original promisor remains enforceable against the delegator.
