(1) in an amount not to exceed the amount of the unissued district bonds approved by the voters; and
(2) for the purpose of carrying out the purposes for which the district bonds were voted.
(b) The bonds are issued under the authority under which they were voted, particularly Section 59, Article XVI, Texas Constitution. The bonds must be secured by a tax under the authority under which they were voted, particularly a tax on the property in the defined area of the abolished district.
