Petitioner's license was suspended under a statute which provided that if a judgment for personal injuries or property damage resulting from the ownership or operation of an automobile remained unpaid fifteen days after it became final, the driver's license should be revoked or suspended until payment and until proof offered of ability to pay future claims. Arrested and jailed for driving without a license, petitioner sought release by writ of habeas corpus on the ground that the statute was unconstitutional. Held, that the operation of the statute was discriminatory and based on an unnatural classification; petitioner discharged. Ex parte Lindley ( Cal. 1930) 291 Pac. 638.
