The pledge of assets or revenue of the authority to the payment of the principal or interest of obligations of the authority is valid and binding from the time the pledge is made and assets or revenue pledged are immediately subject to the lien of the pledge without physical delivery or further action. The lien of a pledge is valid and binding against all parties having claims of any kind in tort, contract, or otherwise against the authority, irrespective of whether those parties have notice of the lien of the pledge. Nothing prohibits the authority from selling assets subject to a pledge, except that a sale may be restricted by the trust agreement or resolution providing for the issuance of the obligations.
