Professor Notes

In Sessions v. Dimaya, the Supreme Court addressed the constitutionality of the residual clause of 18 U.S.C. § 16(b), which provides a definition of 'crime of violence' under immigration law. This case is significant because it reflects the Court's ongoing struggle with the vagueness doctrine in the context of criminal law and due process. The Justices highlighted the importance of providing clear and definitive legal standards that do not leave individuals uncertain about what conduct is prohibited, reiterating the principle that laws must be sufficiently clear so as to avoid arbitrary enforcement.

The case also demonstrates the delicate balance between legislative intent and constitutional protections. Professor emphasis should be placed on the dissenting opinions, particularly Justice Gorsuch's arguments regarding the implications of vagueness in law and potential overreach by the government in immigration enforcement. This case is a vital part of the conversation regarding due process and the rights of noncitizens in the U.S., particularly in relation to deportation based on ambiguous legal definitions.
