According to the Mailbox Rule, Cantu's resignation was deemed accepted when the mail was posted and not when she received it.
After delivering her resignation letter, Cantu sought to rescind the resignation with another withdrawal letter.
Before the withdrawal, however, the Education Supervisor had already accepted her resignation and mailed the acceptance through the post.
The mailbox rule states that acceptance is valid when communicated through the post, at the postal point, and not when received by the recipient.
Thus, the superintendent's decision to refuse the attempted rescission of Cantu's resignation, based on the mailbox rule, is legally binding and upheld.
