If the Supreme Court rules in favor of the investors, and a state then decides to tax all bonds including its own in-state issued bonds purchased by residents of that same state, how will that effect tax-free interest currently being received from that state’s previously purchased tax-free bonds? Will that state’s previously purchased tax-free bonds then be subject to tax by that state? Will currently tax-free interest then be taxed? Or would the tax go into effect only on bonds/interest purchased after a decision to tax them is announced?
