In Vlandis v. Kline (1973) 412 U.S. 441, the United States Supreme Court held that a Connecticut statute's provisions which created an irrebuttable presumption of nonresidency for the purpose of determining tuition and fees was unconstitutional. The court, however, limited its decision, noting: "Our holding today should in no wise be taken to mean that Connecticut must classify the students in its university system as residents, for purposes of tuition and fees, just because they go to school there. Nor should our decision be construed to deny a State the right to impose on a student, as one element in demonstrating bona fide residence, a reasonable durational residency requirement, which can be met while in student status. We fully recognize that a State has a legitimate interest in protecting and preserving the quality of its colleges and universities and the right of its own bona fide residents to attend such institutions on a preferential tuition basis."
