From the Document: "Farm bills, like many other pieces of legislation, have become more complicated and politically sensitive. They are taking longer to enact than in previous decades. Legislative delays have caused the past two farm bills (the 2002 and 2008 farm bills) to expire for short periods, and to be extended for months or a year while a new farm bill was developed. The 2008 farm bill (the Food, Conservation, and Energy Act of 2008, P.L. 110-246) expired twice; the first time was from October 1, 2012 through January 1, 2013, and the second time was from October 1, 2013, through February 6, 2014. Some programs ceased new operations, while others were able to continue. However, neither expiration lasted long enough for the farm commodity programs to revert to an outdated 'permanent law' that would have raised support prices and increased federal outlays. On January 2, 2013, the 2008 farm bill was extended for one year (P.L. 112-240). All provisions that were in effect on September 30, 2012, were extended through FY2013 or for the 2013 crop year. On February 7, 2014, the Agricultural Act of 2014 (2014 farm bill; P.L. 113-79) was enacted to cover the 2014-2018 crop years and other programs through September 30, 2018."
