 In the context of sex-based classifications, intermediate scrutiny applies to constitutional challenges of equal protection and discrimination.An example of a court using intermediate scrutiny came in "Craig v. Boren", 429 U.S. 190 (1976), which was the first case in the United States Supreme Court which determined that statutory or administrative sex-based classifications were subject to an intermediate standard of judicial review.In "Mississippi University for Women v. Hogan" in 1982, the United States Supreme Court ruled that the burden is on the proponent of the discrimination to establish an "exceedingly persuasive justification" for sex-based classification to be valid.
