Whether Horowitz's dismissal implicated a liberty or property interest protected by the Fourteenth Amendment.
Holding
The Court did not decide whether Horowitz had a protected liberty or property interest; it assumed such an interest existed and held that the process she received was constitutionally sufficient in any event.
Reasoning
A procedural-due-process claim ordinarily requires the claimant to identify a liberty or property interest of which the State deprived her. Horowitz did not allege a state-law property interest in continued medical-school enrollment. Instead, she argued that dismissal impaired her ability to continue medical training or obtain medically related employment.
The Court noted that its cases, especially Bishop v. Wood, cast doubt on whether a dismissal creates a protected liberty interest when the allegedly stigmatizing reasons are not publicly disclosed. Here, the school communicated its reasons to Horowitz, but did not publicize them. Rather than resolve that question, the Court assumed a protected interest and addressed the adequacy of the procedures used.
