What happens if the party who proposes an amendment changes their mind before the other party has acted on the proposal? The proposing party can change their mind within the first twelve hours after making the amendment, but it may not be withdrawn after that time. There is not a withdrawal option; the proposing party must wait for the other party to accept or reject the amendment, or wait for the time period to expire. The proposing party can ask the other party to agree to a withdrawal, but the other party is not obligated to agree and may force execution of the amendment. The proposing party may withdraw the amendment
