Justice Neil Gorsuch, President Trump's first Supreme Court appointment, cast the deciding vote in a decision released Tuesday that sided with an immigrant fighting his deportation.
Gorsuch sided with court's four liberal justices in favor of the immigrant, James Garcia Dimaya, who the government sought to deport after his second first-degree burglary conviction in California.
The Justice Department argued his first-degree burglary conviction constituted a crime of violence, which is an aggravated felony that results in deportation under the Immigration and Nationality Act (INA).
However, the court said Tuesday that the law’s definition of a crime of violence is too vague.
In delivering the opinion of the court Justice Elena Kagan relied on a 2015 ruling in which the court said a similar clause in the Armed Career Criminal Act (ACCA) that defined a “violent felony” was unconstitutionally void for vagueness.
