Common questions
Frequently Asked
4
How does sub modo delivery affect a contract under the Restatement?+
A written promise delivered sub modo takes effect only upon occurrence of the stated condition. The promisor retains no power of revocation once the document reaches the promisee, yet the promise remains inoperative until the condition is met.
Does acceptance of goods sub modo preserve breach remedies?+
Acceptance on the reasonable assumption that a nonconformity will be cured preserves the buyer's remedies for breach. The assumption must be reasonable at the time of acceptance. Prolonged use after the promised cure fails may undermine that assumption.
When may a court admit evidence conditionally?+
Evidence whose relevance depends on a preliminary fact may be admitted sub modo if the proponent offers enough proof for a reasonable jury to find the connecting fact. Failure to supply the link later permits striking the evidence or a limiting instruction.
What burden applies when conditional privilege is raised in defamation?+
Once the issue is properly raised, the defendant bears the burden of proving the publication was absolutely or conditionally privileged. The plaintiff need not negate privilege in the first instance.
