Judgments behind this record
Verdict on the claim
Call: Supported
The Analyst says California is home to "a few hundred people with net worth over $1 billion" and describes a one-time tax of 5 percent of net worth. The measure authors' expert report gives both figures: it counts 250 California billionaires on the Forbes list (and refers to the 250 wealthiest Californian taxpayers), and its FAQ calls the tax one on "the 200 or so richest Californians". "Approximately 200" is within the range the Analyst and the report give. The text of Proposition 40 defines net worth as the total value of all assets and property interests of the taxpayer and spouse "worldwide", so "global wealth" matches the text; real property held directly or through a revocable trust and qualified pensions and individual retirement arrangements are excluded. "One-time" matches the Analyst's description. "Modest" is the authors' characterization and is not graded here.

Copy the public log and run its script. It reads only the public log: the signed copy of this record, the judgments behind it, the keys and the receipts. It recomputes each fingerprint and checks the proof, both signatures and the timestamps. It checks the signed copy in the log, not the text on this page:
