Any amounts set aside in such special fund which are not needed to provide for the payment of such items (1), (2), (3), and (4) may be used for any other lawful purpose, to the extent provided in such resolution or trust agreement. Such pledge shall be valid and binding from the time when the pledge is made. Such revenues or other money so pledged and thereafter received by the Authority shall immediately be subject to the lien of such pledge without any physical delivery thereof or further act, and the lien of any such pledge shall be valid and binding as against all parties having any claims of any kind in tort, contract or otherwise against the Authority, irrespective of whether such parties have notice thereof.
Neither the resolution nor any trust agreement by which a pledge is created need be filed or recorded except in the records of the Authority, any public general or public local law to the contrary notwithstanding. The use and disposition of money to the credit of such special fund shall be subject to the provisions of the resolution authorizing the issuance of such bonds or of such trust agreement.
