Boss-Shollei sponsored the Constitution of Kenya (Amendment) (No. 3) Bill, 2019 which sought to ensure that the number of Members of Parliament reflect the requirement of Article 27(8) that not more than two-thirds of the members of elective or appointive bodies shall be of the same gender. The Bill also sought to ensure that the membership of Parliament also reflects the requirement of Article 54(2) of the Constitution that at least five percent of the members of the public in elective and appointive bodies be persons with disabilities.
