A Hinsdale South parent is suing her local school district, Hinsdale Township High School District, and several Hinsdale South employees over the fact that her son did not make the school’s basketball team. The lawsuit, which was filed in the U.S. District Court for the Northern District of Illinois, alleges that Hinsdale South boys basketball coach Michael Belcaster cut her son Brendan after tryouts in the fall in retaliation for the family filing a complaint against the previous coach, Michael Moretti.

Erin Savage, who filed the lawsuit, said that her children had been in varsity sports for 31 years and had never caused a fuss, but in relation to Moretti, she’s “never encountered [someone] who thinks he can do whatever he wants. That was [Moretti].’’

‘‘This is more than just about him being cut from the basketball team,’’ Savage’s lawyer, Steven Glink, told the Chicago Sun-Times. ‘‘This is about what I feel is retaliation of his First Amendment rights. He spoke out against the coach. They substantiated it. The coach got demoted. He tries out for the team, he’s all-conference as a sophomore and junior and now he doesn’t make the team as a senior? That doesn’t pass the smell test in my book.’’

Hinsdale South director of communications Chris Jasculca said the district doesn’t comment on legal matters.
