Substitute House Joint Resolution No. 49 is a resolution passed by the Connecticut General Assembly that rescinds previous applications made to the United States Congress for the calling of an Article V convention. This convention was initially sought for the purpose of proposing amendments to the U.S. Constitution regarding participation in a world federal government and the taxation of income by one state on residents of another state. The resolution indicates that the Connecticut General Assembly no longer wishes for Congress to consider these earlier applications.

Upon passage, the resolution nullifies Senate Joint Resolution 15 from January and Senate Joint Resolution 9 from the 1958 special session. It also directs the Secretary of the State to send certified copies of the resolution to various federal officials, including the Archivist of the United States and members of Connecticut's congressional delegation, with a request for the resolution to be printed in the Congressional Record.
