Kansas Attorney General Paul Morrison has filed a lawsuit with the Kansas Supreme Court, challenging the constitutionality of a newly enacted state gambling law. At the request of Gov. Kathleen Sebelius, a gambling supporter, Morrison filed the lawsuit to obtain an opinion by the high court about whether the law is constitutional. Sebelius was seeking to remove doubt about the measure as casino developers put together plans in four areas of the state.

The Legislature this spring passed the law, allowing casinos in four "zones" -- Wyandotte County, Ford County, either Sedgwick or Sumner counties and either Crawford or Cherokee counties. The bill also would allow slot machines at dog tracks in Wichita and Kansas City, Kan.

But Sedgwick County this month rejected ballot initiatives on both the casino and slot machine questions. A casino is expected to be built in Sumner County.

Morrison's lawsuit, meanwhile, will center on the definition of a "state owned and operated lottery," which is allowed under the Kansas Constitution. Questions exist about whether casinos under the new state law actually will be operated by the state.
