Student banned by coach, parent's rights to sue school or coach to allow son's participation under IL education laws

I do not see this as a matter for the courts. The course manager can (and indeed should) enforce rules including patron exclusion to protect the course. Hopefully your son can control his emotions to enjoy what is a wonderful game, golf.

Government action (violation of a constitutional right) is necessary for a civil rights federal court case and here the school is not preventing your son from playing. Small claims court requires some unreasonable conduct or breach of contract and neither exist here based on what you posted.

Check with a local lawyer to discuss all the details as there is likely more to the story. Perhaps a lawyer can learn all the details and negotiate a good outcome to get your son back onto the course.
