"If your office determines to file such a brief, I respectfully urge that the brief not support the insurance companies' attacks on the HVIRA."

Insurance companies filed a lawsuit earlier this year in federal court in Sacramento, claiming HVIRA is unconstitutional.

In June, a federal judge halted enforcement of the law — which allowed the state to strip uncooperative insurers of their California licenses — on the grounds that it may impair U.S. foreign policy and violate the foreign commerce clause of the constitution.

The state has a Sept. 20 deadline to file a reply brief in the appeals process. An appeals hearing is expected in October, said the state's lead attorney on the case, Frank Kaplan.
