Citizens Link suggests that the decision may have limited impact because few if any other schools have an "all-comers" rule for student groups. Most have a rule that bars discrimination on specified grounds, such as race, religion, gender and sexual orientation. The majority avoided passing on the constitutionality of this sort of rule.
