Catalog Price List Dispute
Cedar Creek Farms mailed a detailed catalog listing prices for its produce to multiple buyers. When Connor Clark responded by ordering a large quantity at the listed price, Cedar Creek refused to ship, claiming the catalog was only an invitation to negotiate. Clark sued for breach. The court held that the catalog lacked any language committing the farm to sell at the stated prices without further assent, so no offer existed.
Miranda Invocation During Interrogation
After arrest, Christian Coleman told officers he might want a lawyer but then answered questions about the crime. The prosecution sought to introduce his statements. The court suppressed them because Coleman never made a clear and unequivocal request for counsel, allowing continued questioning until he did.

Juvenile Admission Without Warning
In a delinquency proceeding, Cameron Cruz admitted to the charged conduct without being told he could remain silent. The court refused to use the admission against him because the record contained no clear and unequivocal evidence that he understood he was not required to speak.

Expressive Association Membership Challenge
The Boy Scouts revoked an adult leader's membership after learning of his sexual orientation. The leader sued under a state public-accommodations law.

Mistake-of-Law Defense in Weapons Case
A corrections officer carried a loaded handgun into a bar, believing his status exempted him from the licensing statute. Charged with unlawful possession, he raised mistake of law. The court rejected the defense because the statute was settled and plain, providing no basis for a clear and unequivocal claim that the officer lacked guilty intent.

Second Amendment Challenge to Handgun Ban
A District of Columbia resident sought to register a handgun for home self-defense but was barred by the city's total prohibition. The resident challenged the ban. The court held that the Second Amendment confers an individual right whose core protection is clear and unequivocal when the law destroys the ability to keep an operable firearm in the home.

Supporting sources
When does an advertisement become an offer rather than mere publicity?+

How does the clear-and-unequivocal standard protect a juvenile's privilege against self-incrimination?+
