Omnibus Election Code
Section 209. Compartment for spoiled ballots. - The ballots deposited in the compartment for spoiled ballots shall be presumed to be spoiled ballots, whether or not they contain such notation; but if the board of election inspectors should find that during the voting any valid ballot was erroneously deposited in this compartment, or if any ballot separated as excess or marked had been erroneously deposited therein, the board of election inspectors shall open said compartment after the voting and before the counting of votes for the sole purpose of drawing out the ballots erroneously deposited therein. It shall then prepare and sign a statement of such fact and lock the box with its three keys immediately thereafter. The valid ballots so withdrawn shall be mixed with the other valid ballots, and the excess or marked ballots shall be placed in their proper envelopes which shall for such purposes be opened and again labelled, sealed, signed and kept as hereinafter provided.
