It is the intent and purpose of this chapter to clarify the statutory framework governing the perfection, priority and enforcement of pledges and liens made or granted in connection with the issuance of public obligations, and to preserve the customary practices with respect to these matters that have developed in the state of Tennessee among issuers and purchasers of public obligations. This chapter provides a uniform and comprehensive statutory framework governing the perfection, priority and enforcement of pledges and liens created by certain state and local governments, governmental entities, agencies and instrumentalities in connection with their issuance of debt obligations, and specifies the extent to which the perfection, priority and enforcement of such pledges and liens are excluded from title 47, chapter 9. If any statute of this state, other than title 47, chapter 9, imposes or authorizes a pledge or lien relating to any public obligations, then that statute, any official action entered into or adopted pursuant thereto, and this chapter, to the extent not in conflict with the foregoing, shall in all respects govern the creation, perfection, priority and enforcement of such pledges and liens, and title 47, chapter 9, shall not govern such matters.
