Young v. Hawaii
In Young v. Hawaii, No. 12-17808, 2018 U.S. App. LEXIS 20525 (9th Cir. July 24, 2018), a panel of the U.S. Court of Appeals for the Ninth Circuit held by a 2–1 vote that "the Second Amendment encompasses the right of a responsible law-abiding citizen to carry a firearm openly for self-defense outside of the home." In other words, this decision upheld the right to open carry as a constitutional right.
The panel was composed of a statistically unusual 2-1 Republican-majority on the Ninth Circuit, where Democrat-nominated judges have an overwhelming majority of 16-7 among active judges. (The Democrat majority among Senior Judges is only 9–8, but a Senior Judge presides in an en banc sitting only if the judge was on the original panel.) If a petition for rehearing en banc is granted, then it seems likely this decision will be overturned.
Petition for rehearing en banc
Hawaii (or the County of Hawaii, or both) filed for a petition for rehearing en banc in this case, and the Court ordered Young to respond by October 9, 2018.
