context: legislatures" instead of calling for plural "applications". States have requested that Congress convene an Article V convention to propose amendments on a variety of subjects. According to the National Archives, Congress has, however, never officially tabulated the applications, nor separated them by subject matter. On at least one occasion though, the "Congressional Record" has included such a tabulation, which indicated that, , thirty states had made a request for a balanced budget amendment. In 1993, professor Michael Paulsen and his research staff assembled a listing of all state applications to date, but neither Paulsen's list, nor any other, can be </s> 700. This is widely considered an overestimate. The House of Representatives is in the process of building its own official count which currently stands at over 120 with 35 states having current live calls that have not been rescinded. This is an underestimate as it so far does not include anything before the 1960s and there are many known Convention calls not yet included. Both Wolf PAC and the Convention of the States estimate, based on spot checking, that the real figure is in the range of 400 calls. Even though the Article V Convention process has never been used </s> has been passed in 12 states. A Super PAC called Single Subject Amendment registered with the Federal Election Commission on March 1, 2013. It is actively engaged in an effort to call an Article V Convention for the limited purpose of proposing an amendment to provide every law enacted by Congress shall embrace only one subject which shall be clearly expressed in the bill's title. Forty-one state constitutions have a single subject provision but this provision is not in the United States Constitution. In April 2014, Florida became the first state to make an application for an Article V Convention
