When the House of Representatives and the Senate fail to agree on any portion of a piece of legislation, conference can be invited by the chamber in which the bill originated in order to work out the differences. When conference is invited, a conference committee is formed to negotiate the compromise. The conference committee is made up of three members of the House of Representatives appointed by the Speaker of the House and three members of the Senate appointed by the Lieutenant Governor. Once a compromise has been reached, the committee issues a conference report which must be signed by at least 2 of the House conferees and 2 of the Senate conferees. The conference report then goes to each chamber for adoption of the full report. A conference report cannot be amended by the full House or Senate, but it can be returned to the conference committee for revision if a chamber votes not to adopt the report.
