The leader of a conservative Kansas think tank and an attorney representing four school districts that sued the state disagree over the effects of Thursday’s Kansas Supreme Court ruling on education funding.

The court invalidated a school funding law enacted last year, saying it violated the Kansas Constitution and was unfair to poor school districts. The court said the law left poor districts $54 million short in their aid for the 2014-15 school year.

Dave Trabert is president of the influential and conservative Kansas Policy Institute. He says the ruling means the state can find a fairer way to distribute more than $4 billion a year in aid without increasing its overall spending.

But attorney John Robb, who’s representing the districts suing the state, says the court specifically said that shifting aid around isn’t sufficient.
