Final answer:
In contract law, if an offeree sends both acceptance and rejection, the first communication received will determine the legal outcome. If the acceptance is received first, a contract will be formed. If the rejection is received first, no contract will exist.
Step-by-step explanation:
If an offeree sends both an acceptance and a rejection, the legal outcome will depend on which communication is received first by the offeror. The principle of "first in time" applies in contract law, meaning that the first communication received will determine the legal status of the offer. If the acceptance is received first, then a valid contract will be formed and the rejection will be disregarded. Conversely, if the rejection is received first, then no contract will be formed.
For example, if the offeree sends an acceptance via email at 10:00 am and later sends a rejection via text message at 11:00 am, if the offeror reads the email first, then a contract will be formed. However, if the offeror reads the text message first, then no contract will exist.
