[5][6] The previous federal judge assigned Monteilh, U.S. District Judge Tucker L. Melancon, in Graham v. Evangeline Parish School Board, was cautioned in an unpublished opinion by the United States Court of Appeals for the Fifth Circuit "to limit itself to traditional judicial decision making rather than school administration, and to refrain from day-to-day management of its decrees."

The court also expressed their concern in regard to Judge Melancon being personally involved in the case and wrote his actions were more administrative than judicial.

The court wrote one could perceive from the record that Judge Melancon had taken over the independent decision making of the school board.

Monteilh requested school construction be enjoined pending preparation of a new consolidation plan.
