Also prior to the 1992 amendment of the Constitution of Kentucky, the lieutenant governor of Kentucky presided over the Kentucky Senate, casting a vote only in the event of a tie. The 1992 constitutional amendment supplanted the office of President pro tempore of the Kentucky Senate with the new office of President of the Kentucky Senate as presiding officer and abolished the lieutenant governor's duties involving the Senate. As a result, the lieutenant governor has no ongoing constitutional duties, and his or her traditional use of the Old Governor's Mansion as an official residence has been phased out.
