What was the US Supreme Court decision in Davis v. Monroe County Board of Education?

Aurelia Davis sued the Monroe County Board of Education, on behalf of her 5th-grade daughter, LaShonda. The suit alleged that the Monroe County Board of Education failed to prevent LaShonda's suffering sexual harassment at the hands of another student. The school's complacency created an abusive environment that deprived her daughter of educational benefits promised her under Title IX of the Education Amendments of 1972. The Supreme Court ruled in favor of Ms. Davis, with a vote of 5 to 4.
