Principal campaign committees of participating candidates must file pre-election reports (Form 3 for House/Senate or Form 3P for President) due 12 days before the special general (pre‑general/pre‑runoff) covering through the 20th day before the election; they also must file 48‑hour notices (Form 6) for contributions of $1,000+ received within 20 days before the election and additional post‑election reports required after the election. (See FEC special‑election filing PDF for CA‑01 for the district‑specific schedule.)
Under California law for special elections, a runoff (Special Runoff Election) is triggered if no candidate receives a majority of the votes in the Special General Election — i.e., no majority winner — requiring the top vote‑getter and runner‑up to contest the runoff.
PACs and party committees that do not file monthly must file supplemental special‑election reports if they make previously undisclosed contributions or expenditures in connection with the special election; they must submit the appropriate report (e.g., Form 3X schedules or 24‑/48‑hour reports for independent expenditures) covering the activity and follow the FEC’s Dates & Deadlines for the CA‑1 special election.
A Hybrid PAC (a ‘‘hybrid committee’’) is a single organization that maintains two separate accounts: one for making independent expenditures and other communications (subject to no contribution limits) and a separate federal account that makes contributions to candidates (subject to federal contribution limits). It differs from other committees by legally separating funds and activity to permit both federal contributions and independent expenditures under FEC rules.
Committees can find exact filing deadlines, expedited pre‑election and 24‑/48‑hour reporting requirements on the FEC’s Dates & Deadlines page and in the CA‑01 Special Elections Filing Information PDF linked from the FEC update; those pages list the calendar‑specific due dates and instructions.
The notice’s wording is incorrect: Representative Doug LaMalfa is alive. No authoritative source reports his death or a vacancy caused by his death; therefore the date of death and vacancy cannot be provided from available information.
The Federal Election Commission administers and enforces federal campaign finance law for federal elections: it issues reporting forms and guidance, sets reporting rules (under the Federal Election Campaign Act and FEC regulations), collects and publishes campaign finance reports, and enforces compliance (including audits and enforcement actions) under its statutory authority.
