Again the VP is master of ceremony and has no authority to reject the votes, only the Congress can do that.
The certificates and other papers relating to the electoral count
are presented and acted on in alphabetical order by states. 3 USC
Sec. 15. Where more than one set of certificates have been received
from a state, and each set purports to be the duly appointed electors
from that state, the Vice President presents the certificates, with
all attached papers, in the order in which they have been received.
Deschler Ch 10 Sec. 3.5.
If there are conflicting electoral
certificates from the same state, the two Houses during the joint
session may, by unanimous consent, determine which certificate is to
be accepted as valid. The tellers may then be directed to count the
votes in the certificate deemed valid. Deschler Ch 10 Sec. 3.5.
Objections
An objection to the counting of any electoral vote must be in
writing and signed by a Member and a Senator. 3 USC Sec. 15; 109-1,
Jan. 6, 2005, p 198. An objection not signed by a Senator is invalid.
107-1, Jan. 6, 2001, p 104; 115-1, Jan. 6, 2017, p__. Objections are
not debatable in the joint session. 3 U.S.C. Sec. 18; 107-1, Jan. 6,
2001, p 104; 115-1, Jan. 6, 2017, p__. In the event that a timely
objection in proper form is raised in connection with the count, the
joint session divides, and the objection is considered by each House
in separate session. Deschler Ch 10 Sec. 3.6; 109-1, Jan. 6, 2005, p
199. The Act of 1887 prescribes the procedure to be followed in debate
after the two Houses have separated. 3 USC Sec. 17. On only two
occasions (in 1969 and 2005) has an objection been perfected,
requiring the two Houses to separate and consider the objection
pursuant to the Act of 1877. 91-1, Jan. 6, 1969, p 146; 109-1, Jan. 6,
2005, p 199. In the House a motion to lay the objection on the table
is not in order. Deschler Ch 10 Sec. 3.7. In one instance the Senate
agreed by unanimous consent to modify the terms set by the statute
with respect to the division of time for debate. Deschler Ch 10
Sec. 3.8.
If either the House or the Senate rejects the objection, the
presiding officer of the joint session directs the tellers to record
the votes as submitted. Deschler Ch 10 Sec. 3.6; 109-1, Jan. 6, 2005,
p 242.
