Seattle King County League says I-638 is likely unconstitutional
League of Women Voters of Seattle King CountyCivic organization, letter by Janet Lenart and Phillippa Kassover
League representatives sign a letter urging a no vote on three initiatives, including I-638. Their I-638 argument is that requiring doctors to certify girl athletes' sex, without a similar requirement for boy athletes, violates privacy and equal protection.
“IL26-638 is likely unconstitutional because it violates Washingtonians' rights to privacy and equal protection by requiring doctors to certify a girl's sex while it has no similar requirements for boy athletes.”
