Mayo Foundation for Medical Education & Research v. United States
562 U.S. 44
SCOTUS2011Background
- Mayo programs train residents for 3–5 years; residents work 50–80 hours/week, primarily caring for patients, under supervision by attending physicians; Mayo paid stipends ($41k–$56k) and provided benefits; residents participate in structured education but time is spent mostly on patient care; Congress exempts certain student services from FICA under § 3121(b)(10); rule change in 2004–2005 defines “incident to study” and excludes full-time employees; Mayo filed suit seeking FICA refunds for 2005; district court granted, appellate court reversed, and certiorari granted.
- Treasury and SSA regulate student exemption; statutory text does not define “student” for medical residents; full-time employee rule defines “not incident to study” based on hours worked; government argues rule is a reasonable Chevron interpretation; Mayo argues rule misreads § 3121(b)(10) and is invalid.
- The Court applies Chevron step one to see if Congress addressed the precise issue; statute silent on medical residents; step two assesses whether rule is a permissible interpretation; the Court concludes Chevron applies and affirms the agency’s interpretation.
- The National Muffler framework is weighed against Chevron; the Court ultimately adopts Chevron Mead framework for tax regulations; the rule is issued after notice-and-comment and under 26 U.S.C. § 7805(a), indicating appropriate delegation; the SSA maintains residents are not students for benefits purposes.
- Court clarifies that while residents are valuable educationally, the § 3121(b)(10) exemption is ambiguous as applied to residents; the Treasury rule is a reasonable construction and the Court affirms the appellate decision.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether medical residents are “students” under § 3121(b)(10) | Mayo argues residents fit the plain meaning of student | Government argues statute ambiguous; rule clarifies predominant educational aspect | Chevron step one finds ambiguity; rule may apply under Chevron step two |
| Whether the full-time employee rule is a valid interpretation | Rule is too categorical and inconsistent with educational nature of residency | Rule is a reasonable, administrable standard distinguishing study from service | Rule is a permissible interpretation under Chevron step two |
| What framework governs review of the Treasury rule | National Muffler should apply for tax regulations | Chevron Mead framework controls for agency tax regulations | Chevron and Mead framework applies; rule sustained |
| Whether Congress directly spoke to residents’ status | Statute does not define student, hence residents could be students | Congress expressly excluded residents from some exemptions, showing no intent to shield them | Congress did not speak directly; ambiguity remains; rule upheld |
