This chapter is not retroactive and does not require redetermination of financial responsibility for cases existing on January 1, 1988. This chapter applies only to applications and redeterminations of eligibility taken or routinely made after January 1, 1988.

Notwithstanding this section, existing social services cases shall be treated in the same manner as cases for those programs outlined in section 256G.02, subdivision 4, paragraph (g), for which an application is taken or a redetermination is made after January 1, 1988.
