When a bill is listed as “Placed in Legislative Files (DEAD)… Pursuant to Joint Rule 310.3,” this means that the bill has been shelved and will not be considered further unless 2/3 of both the House and Senate vote to do so. Joint Rule 310 covers consideration of bills in committees, and Joint Rule 310.3 reads:
310.3 Unanimous Ought Not to Pass Report. When a joint standing committee votes unanimously to report a bill “Ought Not to Pass,” the committee shall notify the presiding officers, the sponsor and the cosponsors of the bill of their action. This communication must appear on the calendar in each chamber, and the bill, upon notification of both chambers, must be placed in the legislative file and may be recalled only as provided in Rule 404.
