Dad,
The Appellate Court decision was in reference to the Kansas Child Support Guidelines as written in January 1999 and as I understand it was a challenge in reference to how the Court interpreted the category of "Special Needs Expenses".
Later versions of the Kansas Child Support Guidelines up to the current date have been changed and further defined.
The Appellate Courts decision in the last two paragraphs = "The child support schedules used to determine the net parental support obligation were based upon national data regarding average family expenditures for children. Administrative Order No. 128, II.C. To state the obvious, most children with means, in this day and age, participate in some form of extracurricular activity. As reflected in the district court's findings, baseball, basketball, soccer, and Boy Scouts are some of the activities that are frequently engaged in by children. By definition, the cost of these activities would be included in the data regarding average family expenditures for children, much like food, school supplies, transportation, and clothing. In turn, the amounts in the child support schedules would also reflect money spent on these activities.
Money spent on extracurricular activities such as baseball, basketball, soccer, and Boy Scouts are normal expenditures already accounted for in the child support schedules. We recommend that the parties seek to agree between themselves on whether the expense of extracurricular activities will be shared in some way."
The current Kansas Child Support Guidelines are based upon USDA data which states directly what expenses it includes in it's calculations. Currently that does not include extracurricular activity expenses. This may have not been the case for the 1999 Kansas Child Support Guidelines.
That would be my assumption with respect to the applicability of the Case Law you inquired about. I would suppose someone would need to take a case to the Appeals Court again to see if the old ruling would prevail despite the facts of how the data is calculated being contrary to the assumptions made by the Appellate court in their 2001 decision.
