Nothing in this chapter is intended to limit the authority of a sanitary district to enter into a lease and leaseback transaction with respect to some or all of its real or personal property, other than land, and to take all other action necessary or desirable, including, but not limited to, the granting of mortgages and liens, to effectuate the transaction. For purposes of this section, "lease" includes a lease of any length, including leases that may be defined as sales for income tax purposes.   [PL 2003, c. 267, §2 (NEW).]
