Major news breaking Friday in the city of Topeka.

District Attorney Robert Hecht has filed a lawsuit against the city over its deal to buy a police helicopter.

Hecht says he has to fulfill Kansas law and that he had three major areas of contention.

At a press conference Friday Hecht said the city broke Kansas law when entering into the purchase agreement. Hecht disputed the council's use of a communication authorizing the purchase and said it violated governmental checks and balances in okaying the deal as to the expense of a suit…

"I wouldn't anticipate that this would be a very expensive process for the city of Topeka, although knowing the city of Topeka they have a way of being able to spend more money then anybody would anticipate,” Hecht said.

Topeka mayor, Bill Bunten hopes the suit will ensure that both sides are heard, “My position is simply that the D.A. will argue his position the city attorney will argue his position and a judge will make a decision as far as who is correct and will abide by that decision. "

"The litigation will proceed in an orderly fashion and we hope the court will ultimately agree with the position of this office and I would not anticipate that there would be a decision on this for a number of months,” Hecht added.

Other city leaders say they need time before they can respond.

"We just got the document, we will have to thoroughly review it and respond,” City Manager, Norton Bonaparte said Friday.
