ST. LOUIS, MO — The mother of a Ladue High School student took her case to the federal courthouse after her son, called John Doe in legal documents, did not make the varsity soccer team and was not allowed to play on the J.V. team. The woman’s attorney said the issue is age and sex discrimination. Friday morning Ladue school officials said if a junior does not make the varsity team, the boy cannot play again on the junior varsity team. The school said this is to allow lower grade students a chance to develop their skills so that they will be prepared to try out for varsity.
