A bill winding its way through the California Legislature would make some of the most significant changes in decades to the state’s 58-year-old Public Records Act, according to the Associated Press. The measure, AB 1821, has split lawmakers and activists over whether it would streamline overwhelmed government offices or erect new barriers to public access.

Proponents of the bill argue it is necessary to help local governments weather a deluge of burdensome public records requests that have swamped cities and other local agencies, the AP reported. They say the current system places an unsustainable strain on staff and resources.

But the changes proposed in AB 1821 have alarmed First Amendment groups, many news organizations, and government watchdogs, who worry it will allow officials to delay handing over records and impose financial barriers to information access, according to the AP. Critics say the bill could fundamentally weaken the California Public Records Act, a law that guarantees everyone the right to obtain government documents and data.

So far, Oakland’s political leaders have backed the bill. In early May, the Oakland City Council voted unanimously to support it. Later in May, East Bay Assemblymembers Buffy Wicks and Mia Bonta each voted to advance the bill out of the Assembly chamber and onto the state Senate. The version they supported would make one specific change: giving officials several more days to respond to a records request, according to the AP.

The bill now moves to the state Senate for consideration. Its path through the Legislature comes as California continues to debate the balance between efficient government operations and the public’s right to know what their government is doing. Transparency advocates say they will be watching the Senate proceedings closely, warning that even a modest extension of response times could compound into significant delays for citizens and journalists seeking information.
