Toll v. Moreno: Maryland Could Not Deny In-State Status Solely Because of G-4 Immigration Status

Decision: Toll v. Moreno, 458 U.S. 1 (1982).

Toll v. Moreno involved dependents of international-organization employees who were denied in-state tuition even if they were domiciled in Maryland. Earlier litigation had established that G-4 status did not prevent acquiring domicile. The university then clarified that its exclusion of nonimmigrant students would apply regardless of the ordinary domicile rules. That change made the case more than a dispute over whether these particular students had proved residence. Toll, 458 U.S. at 3–8.

Congress had not required G-4 visitors to maintain a foreign residence

Unlike some nonimmigrant categories, the governing federal classification did not impose a continuing foreign-residence requirement inconsistent with forming domicile in a state.

The state added a disability not selected by Congress

Maryland’s conclusive rule imposed a special burden solely on a federally admitted immigration class and upset the conditions Congress chose for that class. The Court also relied on federal tax privileges for organizational salaries: Maryland could not use higher tuition to recoup taxes that federal law barred it from collecting. Toll, 458 U.S. at 14–17.

Ordinary domicile proof could still be required

The student still had to satisfy neutral state domicile criteria applied to other applicants.

Present classifications require current analysis

Visa statutes, tuition laws, and federal restrictions on public benefits have changed. The exact status, state rule, and current federal law control.

Justice O’Connor agreed only in part. She accepted the conflict where federal law exempted the particular G-4 families from both federal and state income tax, but distinguished those whose federal exemption did not itself prevent state taxation. Justice Rehnquist, joined by Chief Justice Burger, dissented. He would have required a more specific conflict with federal law and considered higher tuition a charge for educational services rather than a tax on protected salaries. He also favored rational-basis review of the state classification and would have reversed. Toll, 458 U.S. at 24–49 (separate opinions).

Justice Blackmun joined the Court but separately defended heightened scrutiny of alienage classifications affecting economic interests. He distinguished the political functions for which citizenship can be relevant from ordinary economic participation and rejected the suggestion that excluding noncitizens from voting weakened the reason for judicial protection. That constitutional discussion was his response to the dissent; the Court’s decision here rested on federal supremacy. Toll, 458 U.S. at 19–24 (Blackmun, J., concurring).

Key takeaways

• Identify the visa classification and its federal conditions.
• Collect ordinary evidence of state domicile.
• Distinguish a categorical status bar from neutral residency criteria.
• Check current federal benefit and state tuition statutes.
