After three split roll calls, Supervisor Kenneth Hahn changed his mind and provided Philibosian the vote he needed.

Proposition 15 would have created a “split roll” system, in which residential property would continue to be shielded from tax increases but commercial property would not.

Property management firms, business lobbies and real estate developers contributed more than $50 million to defeat Proposition 15, which would have created a “split roll” to allow more frequent assessments of commercial and industrial property.

Instead, the ballot measure asked voters to embrace the most talked-about idea for changing Proposition 13, a “split roll” of business properties that could be taxed based on market value.

Supporters of the split roll idea carefully chose their timing, believing the fall election this year would attract a high turnout of voters sympathetic to the idea of a tax increase on big business.
