“I can assure you that the joint and co-authors on this bill ... have endeavored to build in protections in this law that are stronger than the protections in any of the states where this has been practiced,” said Sen. Bill Monning, D-Carmel.

The bill continued to face fierce opposition, however, from religious groups and disability rights advocates. They are concerned that elderly and disabled people, especially those who are low income, could be pressured into taking the drugs in order to end or avoid expensive, life-sustaining care. They fear the protections are not enough, and that family members or other heirs could slip the drugs to the patient without their knowledge or consent.

“The legislation effectively paints a target on the back of each and every elderly and disabled person in our state,” said Sen. Joel Anderson, R-San Diego, paraphrasing an elder abuse advocate. “The promises and assurances of the safeguards and protections from the representatives of those in favor are based in innocent ignorance.”

Opponents also criticized the procedure for getting the bill through the Legislature. During the normal legislative session, the bill stalled in the Assembly Health Committee when authors couldn’t get enough votes. Several Democrats from Southern California would not support it.

But proponents managed to navigate through that roadblock by re-introducing the bill during a special session on health care financing, where committee memberships were different. The bill passed the Assembly on Wednesday 44-35, and it passed the Senate on Friday 23-14.

Gov. Jerry Brown’s office also criticized the political pathway, saying the special session was not the appropriate venue for the physician-assisted suicide bill. But Brown has not indicated where he stands on the issue itself, nor whether he will sign or veto the bill. If he does nothing, after 30 days the bill will become law.
