The single subject amendment is a proposed amendment to the United States Constitution that would impose the single-subject rule on federal legislation, limiting the content of bills introduced in Congress to a single subject.
The amendment would have the effect of limiting legislative tactics such as logrolling, earmarks, and pork barrel spending.
[1] It would also discourage the use of very long omnibus spending bills which are difficult for legislators to read and analyze in the time frame needed for a vote, and to which unrelated riders are often added late in the legislative process.
[1] A federal amendment was proposed as early as 1999 in a law journal article by Brannon Denning and Brooks R.
[2] The Florida Legislature in 2014 passed a memorial applying to Congress to call a convention for this purpose.
