Catalog Price List Lacks Commitment
Ulysses Usher mailed a detailed catalog listing prices for industrial parts to potential buyers. When Ulric Unger replied ordering a large quantity at the listed price, Ulysses refused, claiming the catalog was only an invitation to negotiate. The court examined whether the catalog contained unequivocal language of commitment. Because the catalog merely stated suggested bargains without inviting immediate acceptance, it failed the unequivocality requirement and was held not to be an offer.
Will Reformation Requires Clear Proof
Ugo Uberti's will left his entire estate to a named charity, yet his attorney testified that Ugo had repeatedly stated an intention to divide the estate equally among three nieces. The nieces sought reformation. The court required clear and convincing evidence both that a mistake affected the document and what Ugo's true intention was. The nieces' evidence, though consistent, did not rise to the level of unequivocal proof needed to overcome the plain text.

Trust Instrument Mistake Claim
Ulrike Ulrich executed a trust naming her brother as sole remainder beneficiary. After her death the niece produced notes showing Ulrike intended to include the niece as a co-beneficiary. The niece petitioned for reformation under the Uniform Probate Code. The court held that the notes, standing alone, did not constitute unequivocal evidence of both the mistake and the intended disposition, so reformation was denied.
Second Amendment Challenge
Umar Underwood challenged a local handgun ban as violating the Second Amendment. The District argued the ban was a permissible regulation of the manner of exercising the right. The Court examined whether the historical understanding of the right was unequivocal. Finding that the right to keep and bear arms for self-defense was clearly established at the founding, the Court struck down the ban.

Commerce Clause Gender Violence
Ursula Upton sued under the Violence Against Women Act after suffering gender-motivated violence. The defendant moved to dismiss, arguing Congress lacked power under the Commerce Clause. The Court assessed whether the regulated activity had an unequivocal substantial effect on interstate commerce. Because the connection was too attenuated, the Court held the civil remedy provision exceeded congressional authority.
United States v. Morrison529 U.S. 598 (2000)
Miranda Request Must Be Clear
Uptown Apparel's employee was in custody and told officers he might want a lawyer. The officers continued questioning. The employee later moved to suppress his statements. The Court held that a request for counsel must be unequivocal and specifically tied to interrogation. Because the statement was ambiguous, the officers were not required to stop, and the statements were admissible.

Common questions
Frequently Asked

How does unequivocality affect reformation of donative documents?+
Reformation requires clear and convincing evidence of both a mistake and the donor's true intention. Direct evidence contradicting the plain text may be considered, but the evidence must be sufficiently unequivocal to overcome the presumption favoring the written terms. Courts therefore demand a high degree of certainty before altering an unambiguous instrument.
When is a request for counsel considered unequivocal under Miranda?+
A Fifth Amendment request must be unambiguous and specifically related to custodial interrogation. Ambiguous statements such as "I might want a lawyer" do not trigger the right to counsel. Officers may continue questioning until the suspect makes a clear invocation.
What role does unequivocality play in proving abandonment of a servitude?+
Abandonment requires unequivocal evidence that the beneficiary intended to extinguish the servitude permanently. Mere nonuse, even for a long period, is seldom enough. Affirmative acts or statements inconsistent with continued existence of the servitude are normally required.
384 U.S. 436 (1966)Evidence
…be observed. At the outset, if a person in custody is to be subjected to interrogation, he must first be informed in clear and unequivocal terms that he has the right to remain silent. For those unaware of the privilege, the warning is needed simply to make them aware of it—the threshold requirement for an intelligent decision…
