This application concerns an important issue that this Court is likely to be required to address in the near future, namely, whether either Title IX of the Education Amendments of 1972, 86 Stat. 373, 20 U. S. C. §1681 et seq., or the Fourteenth Amendment’s Equal Protection Clause prohibits a State from restricting participation in women’s or girls’ sports based on genes or physiological or anatomical characteristics.
