Introduction Read the overview below and complete the activities that follow. Mailbox Rule A freak jet-ski accident caused the worldwide Internet and telephone system to crash for a full month in the summer of 2018. This forced businesses everywhere to contract by paper mail. During that time, two major oil companies Denver- Carrington Associates and Colby Co Energy struggled to close a land deal with Mathis Holdings LLC. CONCEPT REVIEW: If a contract is negotiated in person, everyone present understands in real time what is going on. Once the offer is accepted, everyone knows immediately that a contract has come into existence. Once an offer is revoked, everyone knows immediately that the process has stalled. Contracting by mail, on the other hand, involves a lot of waiting. This means that neither party can know the other's intentions in real time: the offeree has no way of knowing at any given moment whether the offeror is still interested in a contract, and if the offeree signs, the offeror will not know a contract has been created for some time. Under these circumstances, the mailbox rule determines when offer, revocation, and acceptance have definitively taken place. A timeline of events is given below. Match these events with their significance: Has an offer been made? Has a contract been formed? Has anything legally significant happened at all? Invitation to negotiate. Revocation.
