HRS §490:2-610
What to do when the other side backs out early
If one party clearly says they won't perform a future duty that would seriously hurt the other party, the hurt party can wait a reasonable time or treat it as a breach and use legal remedies. They can also pause their own duties or take steps to protect goods.
