"You swear (or affirm) that the statements and information you shall give in this hearing with respect to your identity and qualifications to be registered and to vote shall be the truth, the whole truth, and nothing but the truth, so help you, God."
After swearing the challenged registrant, the board shall examine him as to his qualifications to be registered and to vote. If the challenged registrant insists that he is qualified, the board shall tender to him the following oath or affirmation:
"You do solemnly swear (or affirm) that you are a citizen of the United States; that you are at least 18 years of age or will become 18 by the date of the next general election; that you have or will have resided in this State and in the precinct for which registered for 30 days by the date of the next primary or election; that you are not disqualified from voting by the Constitution or the laws of this State; that your name is ____, and that in such name you were duly registered as a voter of ____ precinct; and that you are the person you represent yourself to be, so help you, God."
If the challenged registrant refuses to take the tendered oath, or submit to the board the affidavit required by subsection (d), below, the challenge shall be sustained. If the challenged registrant takes the tendered oath, the board may, nevertheless, sustain the challenge if it finds the challenged registrant is not a legal voter.
The board, in conducting hearings on challenges, shall have authority to subpoena any witnesses it may deem appropriate, and administer the necessary oaths or affirmations to all witnesses brought before it to testify to the qualifications of the persons challenged.
