From Ammoland:

The lawsuit centers around Hawaii’s requirements on gun owners along with Honolulu Police Department’s registration and gun policies. Gun owners must apply for a firearm permit in person at the central police station on Oahu. This rule means that a gun must travel to the police station in Honolulu to apply for a gun permit no matter where they live on the island. The resident must then return to the station in person 14 days later to pick up the permit. Once the person acquires a firearm, they must then again return to the station with the gun to register it with the police department.
