What is the old rule of impossibility from Stees v. Leonard?
“If a man binds himself, by a positive, express contract, to do an act in itself possible, he must perform his engagement, unless prevented by the act of God, the law, or the other party to the contract. No hardship, no unforeseen hindrance, no difficulty short of absolute impossibility, will excuse him from doing what he has expressly agreed to do.”
If someone binds themselves to some action, nothing short of absolute impossibility will excuse that performance.
