Since 2009, all fifty states and the District of Columbia have enacted statutes to improve prevention and treatment of concussions in youth sports.

The passage of time will determine the efficacy of this new legislation and the desirability of further amendments, but, as I argue in a forthcoming law review article to be published by the Journal of Business & Technology Law (a copy of which is attached as a pdf), one major shortcoming of many of the new state concussions statutes is that regulate only interscholastic sports, and do not extend to private leagues, clubs and associations which do not own and operate their own facilities but instead use fields, gymnasiums, and other public property managed by local governmental bodies, usually the city council, the parks and recreation department, or the public school district.
