one-house bill
n.— «It seems many in the Capitol press corps chose to let this story go by because the legislation is what’s known in Albany parlance as a “one-house bill.” That is, it doesn’t have a sponsor in the other house (the Assembly, in this case), and it’s not going anywhere, practically speaking.» —“No More School Taxes—Just Kidding!” by Erika Rosenberg Policy Wonk (New York) June 18, 2007.
