§ 10733 Catastrophic Congressional Vacancy Elections
This law tells how and when to hold a special election to fill a House seat when a big disaster knocks out many members, especially if it hits California a lot.
A massive earthquake wipes out 120 members of the U.S. House, including two from California.
Because more than 101 seats are empty, the Speaker announces the vacancy and the Governor must call a special election within one day. The election has to be held on a Tuesday no later than 49 days after the announcement.
If Vacancies ≥ 101 → ElectionDate ≤ AnnouncementDate + 49 days; If Vacancies_CA ≥ (Total_CA_Seats ÷ 4) AND Vacancies < 101 → ElectionDate ≤ GovernorProclamationDate + 49 days; Consolidation allowed if LocalElectionVoters ≥ 0.5 × VacancyVoters and ElectionDate ≤ ProclamationDate + 75 days.
120 vacancies nationwide (including 2 in California). Total California seats = 53.
Result: Because Vacancies ≥ 101, the election must be on a Tuesday no later than 2024-04-19 (49 days after March 1).
