Telecom Offer Lapses After Delay
Prime Wireless sent West Broadband a written proposal for fiber service on January 15 with no stated deadline. West Broadband signed and returned the document on May 15 after completing an office move. The four-month gap caused the power of acceptance to end, so no contract formed when Prime refused the late response.
Tort Causation Shifted by Delay
A factory released pollutants that posed a risk of groundwater harm. After several years passed without cleanup, a third party’s independent dumping became the dominant source of contamination. The extended interval caused the original actor’s responsibility for the final harm to terminate under apportionment rules.

Duty to Prevent Harm Transfers
A contractor left an excavation site unsecured after completing work. Two years later a neighboring property owner failed to install barriers, allowing a pedestrian to fall. Because of the passage of time the duty to warn or protect shifted away from the contractor, making the neighbor’s inaction a superseding cause.
Lease Expires Without Renewal
Equinox Energy leased warehouse space from Everest Holdings for a five-year term ending December 31. Neither party gave notice or took any action to extend the lease. On January 1 the tenancy terminated automatically, returning possession to the landlord without any affirmative termination notice.

Common questions
Frequently Asked
4
How does effluxion of time terminate an offer under contract law?+
An offeree’s power of acceptance ends when a reasonable time passes without acceptance, even if the offer contains no explicit deadline. Courts measure reasonableness by market conditions, subject matter, and the parties’ communications. Once that period expires, the offer lapses and cannot be revived by a late acceptance.
Supporting sources
Does effluxion of time affect tort causation analysis?+
Yes. When substantial time passes after negligent conduct, the original actor’s duty to prevent harm may shift to a third person. The later failure of that third person then becomes a superseding cause that cuts off the original actor’s liability.
Supporting sources
What is the difference between effluxion of time and revocation of an offer?+
Effluxion of time terminates the power of acceptance automatically once a reasonable period expires, without any action by the offeror. Revocation requires an affirmative communication from the offeror before acceptance occurs. Both end the power, but only revocation depends on the offeror’s conduct.
Supporting sources
Can effluxion of time bar a tort claim even without a statute of limitations defense?+
No. A tort claim is barred by lapse of time only when a statute of limitations applies. The mere passage of time alone does not extinguish the claim unless the statute has run.
