California Court Backs Insurer Right to Charge More for Unmarried Drivers

The ruling in Ison v. Lara permits insurers to maintain marital status as an optional component when calculating auto insurance premiums. According to data cited in the case, this practice results in unmarried drivers paying roughly $56 to $100 more than married counterparts for identical coverage. Consumer groups point to specific examples, such as a 2025 test where a single driver faced a 32 percent premium hike compared to a married driver with an identical profile.

While the majority sided with the Commissioner, the decision sparked a forceful 30-page dissent from Presiding Justice Alison M. Tucher. She argued that the Unruh Civil Rights Act, which explicitly lists marital status as a protected class, should prohibit such price discrimination. Tucher maintained that the Commissioner lacks the authority to exempt insurers from these civil rights mandates, regardless of any business or actuarial justifications offered by the industry.

William Pletcher, litigation director for Consumer Watchdog, criticized the ruling as an endorsement of discriminatory practices. He noted that the policy penalizes individuals based on personal circumstances rather than driving performance. As the legal battle concludes for now, the decision leaves in place a regulatory framework that allows insurers to diverge from the standard protections afforded to other groups under California law.
