GREAT FALLS, Mont. -

The owners of several Great Falls casinos will be able to keep their nearly fully enclosed "smoking shelters" that also house gambling machines after a District Court judge ruled they do not violate the Clean Indoor Air Act.

However, the administrator of the state Gambling Control Division said his department is investigating whether the shelters meet legal requirements for video gambling machine establishments because there is a 4-inch separation between the walls and the ceiling to allow the smoke to vent. State law requires video gambling machines to be in enclosed public spaces.

The Great Falls Tribune reports District Judge Greg Pinski issued his summary judgment on Nov. 19 in the lawsuit filed by casino owners Douglas and K.C. Palagi and their attorney and business partner Gregg Smith.
