If it’s true that the measure of any successful compromise is that few are fully satisfied, then the California State Bar’s Board of Governors cooked up a good deal on malpractice insurance.

The board voted 16-4 on Friday to finally approve new rules on coverage disclosure, an issue that’s been festering there for two years. Under the compromise — which still must be approved by the state Supreme Court — lawyers who expect to bill a client for more than four hours must pipe up if they aren’t covered for malpractice.
