"[29] disabled people and one parent of a disabled person … filed lawsuits ... with district courts in their prefectural capitals contending that a law designed to help disabled people violates the Constitution … Under the law, disabled people in principle must pay 10 percent of the costs of the welfare and medical benefits they receive - a departure from the earlier principle of having disabled people pay according to what they could afford. The plaintiffs say the law violates ... Articles 13, 14 and 25 of the Constitution." (Quoted from article)
