La. R. Sup. Ct. 1
When it appears to the Supreme Court of the United States, to any circuit court of appeal of the United States, or to any district court of the United States, that there are involved in any proceedings before it questions or propositions of law of this state which are determinative of said cause independently of any other questions involved in said case and that there are no clear controlling precedents in the decisions of the supreme court of this state, such federal court before rendering a decision may certify such questions or propositions of law of this state to the Supreme Court of Louisiana for rendition of a judgment or opinion concerning such questions or propositions of Louisiana law. This court may, in its discretion, decline to answer the questions certified to it or reformulate the question certified.
