What is the test for an exemption under section 25655 of the California Civil Rights Act?

Defendant asserts that the exemption under section 25655 is "largely illusory" because the "heightened requirement for good cause" under these policies "makes it virtually impossible for a law-abiding citizen to obtain a license to carry a concealed firearm." He therefore challenges the policies governing concealed carry, asserting that absent these unconstitutional restrictions, he would have been able to lawfully carry his concealed handgun in his vehicle. We review questions of constitutional law de novo. (People v. Cromer (2001) 24 Cal.4th 889, 893-894.)
