The judicial panel, composed of Julie Genovese, Emily Lonergan, and Mark Sanders, argued that it lacked the authority to rule on the matter. In an 18-page ruling, the judges explained that the Wisconsin Supreme Court did not provide them with proper guidance when assigning them the case. Therefore, they concluded that they did not have the authority to supersede the decisions of the state Supreme Court.
The lawsuit, filed by 11 Wisconsin residents last July, alleged that the state's congressional map violated the separation-of-powers doctrine and resulted from "unlawful partisan gerrymandering". The Wisconsin Supreme Court appointed the panel to the case in November.
