MADISON, Wis. (AP) — Republicans want to keep any legal battle over redistricting Wisconsin in the state Supreme Court, starting the legal fight over the redrawing of political boundary lines a full year before any new maps are created.

Former Republican Assembly Speaker Scott Jensen, along with the conservative Wisconsin Institute for Law and Liberty law firm, submitted a legal filing Wednesday with the state Supreme Court.

It seeks a rule change to require that any legal challenges over redistricting be handled by the conservative-controlled Wisconsin Supreme Court, not federal courts.
