Republican Gov. Sam Brownback is calling for a fresh round of aggressive cuts in Kansas income taxes and changes in the state Constitution to rein in the judiciary.

Brownback reaffirmed in the prepared version of his State of the State address Tuesday evening that his goal is to eventually eliminate income taxes. But his plan for further reductions is tied to keeping the state sales tax at its current rate, rather letting it drop in July as previously planned.

Brownback’s speech came just days after a three-member panel of trial judges ruled the state must boost its annual aid to public schools by at least $440 million.

Brownback endorsed proposed constitutional amendments on education funding and the selection of judges for the Court of Appeals and the Supreme Court.
