Mahonia Ltd. v JP Morgan Chase Bank

Mahonia Ltd. v JP Morgan Chase Bank

There is at least a strongly arguable case that a letter of credit integral to an illegal transaction cannot be enforced, even if the bank was unaware of the illegality at the time of payment, where clear evidence of illegality is available at trial. The autonomy principle does not override public policy against enforcing contracts entered into for an unlawful purpose.
