Ohio constitution
Article II: legislative
Section 16

If the governor approves an act, he shall sign it,
it becomes law and he shall file it with the secretary
of state.
If he does not approve it, he shall return it with his objections
in writing, to the house in which it originated,
which shall enter the objections at large upon its journal,
and may then reconsider the vote on its passage.
If three-fifths of the members elected to the house of
origin vote to repass the bill, it shall be sent, with the
objections of the governor, to the other house, which
may also reconsider the vote on its passage. If three
fifths of the members elected to the second house vote
to repass it, it becomes law notwithstanding the objections
of the governor, and the presiding officer of the
second house shall file it with the secretary of state. In
no case shall a bill be repassed by a smaller vote than
is required by the constitution on its original passage.
In all cases of reconsideration the vote of each house
shall be determined by yeas and nays, and the names
of the members voting for and against the bill shall be
entered upon the journal.
If a bill is not returned by the governor within ten days,
Sundays excepted, after being presented to him, it becomes
law in like manner as if he had signed it, unless
the General Assembly by adjournment prevents its return;
in which case, it becomes law unless, within ten
days after such adjournment, it is filed by him, with his
objections in writing, in the office of the secretary of
state. The governor shall file with the secretary of state
every bill not returned by him to the house of origin
that becomes law without his signature.
The governor may disapprove any item or items in
any bill making an appropriation of money and the
item or items, so disapproved, shall be void, unless
repassed in the manner prescribed by this section for
the repassage of a bill.
