In the California legislature, the following items require a two-thirds majority vote to pass:
1. Proposed constitutional amendments: Any proposed changes to the state constitution must receive a two-thirds majority vote in both houses of the California legislature to pass.
2. Overrides of a veto: If the governor of California vetoes a bill, the legislature can override the veto with a two-thirds majority vote in both the Assembly and the Senate.
It's important to note that not all items listed in the question require a two-thirds majority vote in the California legislature. For example, environmental bills, budget bills, urgency measures, propositions on the ballot, and referendums do not necessarily need a two-thirds majority vote for passage.
