YEAS AND NAYS - The
list of members of a legislative body voting in the
affirmative and negative of a proposition is so called.
The Constitution of the United States, Art. 1 directs
that "the yeas and nays of the members of either
house, on any question, shall, at the desire of one-fifth
of those present, be entered on the journal."
The power of calling the yeas and nays is given by
all the Constitutions of the several states, and it
is not in general restricted to the request of one-fifth
of the members present, but may be demanded by a less
number and, in some, one member alone has the right
to require the call of the yeas and nays.
