California Code, Elections Code - ELEC § 15632

In lieu of the returns as reported in the official canvass, upon completion of the recount showing that a different candidate was nominated or elected, that a different presidential slate of electors received a plurality of the votes, or that a measure was defeated instead of approved or approved instead of defeated, there shall be entered the result of the recount in each precinct affected, which result shall, for all purposes thereafter, be the official returns of those precincts for the office, slates of presidential electors, or measure involved in the recount. If the office, slates of presidential electors, or measure are not voted on statewide, the results of any recount which is not completed by counting the votes in each and every precinct in the jurisdiction within which votes were cast on the candidates for the office, on the slates of electors, or on the measure in question shall be declared null and void. If the office, slates of presidential electors, or measure are voted on statewide, the results of any recount will be declared null and void where there is not recounted each vote cast statewide for the office, slates, or measure.
