Slip and fall at one of California’s 57 Indian casinos and you might have a case in court. But hurt yourself at another of them, perhaps one just miles down the highway, and your claim might be headed to a tribal council. Or to arbitration. Or to a claims adjustor. Or nowhere at all.

Ten years after Gov. Pete Wilson signed the first compact with a tribe allowing Las Vegas-style slot machines in California, personal-injury and property-damage protections in Indian casinos vary as widely as the tribes themselves.
