California could end up facing a slew of challenges to gun control laws following Monday's Supreme Court ruling recognizing the second amendment as a fundamental right in state and local jurisdictions, experts say.

The Supreme Court decision, which effectively removes Chicago's three-decade old ban on handguns, also bolsters a California case – Nordyke vs Alameda County. In that case, 9th Circuit Court justices applied the right to bear arms to the state constitution.

With those victories in hand, gun enthusiasts now say they are preparing to attack about a dozen laws in California that they believe unreasonably restrict gun ownership.

"California has a lot of unreasonable restrictions and we can prove it beyond a reasonable doubt," said Greg Block, a Huntington Beach firearms trainer and a member of CalCCW.com, one of the groups preparing to mount the challenges.

Block said members would take aim at, among other things, the restriction allowing only one handgun to be purchased in a 30-day period; the restriction limiting rounds in a magazine to 10 and the regulations allowing sheriff's and police chiefs to determine who can carry a concealed weapon.

Block said 40 states have less restrictive regulations on concealed weapons permits – which in Orange County are overseen by Sheriff Sandra Hutchens. Hutchens has angered gun advocates by her austere approach to issuing permits.

"This is a huge victory because it affirms the state cannot (regulate) against the U. S. Supreme Court and that's what Chicago tried to do," Block said.

Meanwhile, law enforcement officials weren't much worried that California's gun laws would fall to a flood of challenges. The Supreme Court had ruled that states and local governments have the right to impose reasonable restrictions on the second amendment.

Hutchens believes the ruling will have no immediate impact in the county. Pending that they pass a background check, people in Orange County are allowed to purchase and keep guns in their homes, she said.

"It's easy to file a lawsuit," said Martin Mayer, a Fullerton attorney who represents the California State Sheriff's Association and the California Police Chiefs Association. "But I don't see a major change as long as you are reasonably regulating."

San Jose attorney Donald Kilmer, who represented gun advocates in the Nordyke case, has a different view of "reasonably regulated."

Kilmer said California gun laws would be put under a microscope and given greater scrutiny.

"California is going to have to talk the talk and walk the walk when they say a gun is illegal in California," he said.
