Resolution criteria

This market will resolve to YES if the California State Legislature successfully overrides any gubernatorial veto (either a full bill veto or a line-item veto) between the creation of this market and December 31, 2027, at 11:59 PM PT. Otherwise, this market will resolve to NO.

To qualify as a successful veto override:

• Both chambers of the California State Legislature (the State Senate and the State Assembly) must vote by a two-thirds supermajority to override a veto issued by the Governor of California.

• The bill (or the overridden portion) must successfully become law as a result of this vote.

Sources of verification:

• California Legislative Information (Official bill tracking and status)

• Office of the Chief Clerk of the Assembly / Secretary of the Senate

• Major state news publications (e.g., CalMatters, Los Angeles Times, or The Sacramento Bee)

Background

Under Article IV, Section 10 of the California Constitution, overriding a governor's veto requires a two-thirds vote in both the State Assembly (54 of 80 members) and the State Senate (27 of 40 members). Under Joint Rule 58.5, the legislature has 60 calendar days (excluding joint recesses) to act on a veto once the bill is returned.

Despite a long-standing Democratic supermajority in both chambers, the California Legislature has not successfully overridden a gubernatorial veto since 1979/1980, when lawmakers overrode four vetoes by then-Governor Jerry Brown. While hundreds of bills pass both chambers with more than two-thirds support each session, vetoes are traditionally left unchallenged once returned to the legislature.
