of the Assembly and the President of the Senate. These high level positions reflect the party majority in both chambers. An amendment to the state constitution in 1979 removed the Lieutenant Governor of Wisconsin as the presiding officer of the Senate, allowing Senators to vote within their ranks for a chamber president. Similarly, majority and minority leaders are also selected by party strength in the legislative houses and within their own respective caucus. Salary and benefits Legislators in both the Senate and the Assembly receive an annual salary of $55,141. Senators receive per diem of up to $115 to cover living expenses when they are in Dane County, Wisconsin on state business, unless their district is in Dane County, in which case they receive per diem of up to $57.50. Assembly members outside of Dane County receive overnight per diem up to $155. Otherwise, they receive $76.50 per diem, the same rate as assembly members in Dane County. Legislators also receive $75 per month in "out-of-session" pay when the Legislature is in session for three days or less. Over two years, each legislator is allotted $66,008 to cover general office expenses, printing, postage and district mailings. Rules and procedures In both chambers of the Wisconsin Legislature, a quorum is defined as a majority of current members. The majority of a quorum is needed to pass legislation on the floor of the chamber. Three-fifths of the members elected is the quorum necessary for passage or concurrence in either house of any fiscal bill. Proposals may not be introduced or offered unless they are put in proper form by the legislative reference staff if requested by members or members-elect of the legislature. Both houses of the legislature review a bill before it becomes law, and if each chamber approves the bill, the state's Governor will review it. If the Governor signs the bill, it passes into law, but if the Governor vetoes the bill, it will return to the legislature. It is possible for the legislature to override a veto and pass the bill into law itself, but this requires a two-thirds majority vote in both the Senate and the State Assembly. Law of Wisconsin State law is contained in the Wisconsin Constitution and the various statutes enacted by the Legislature. The interpretation of state law and its application in specific cases are undertaken by the Wisconsin Supreme Court, based in Madison,
