In the
Democratic Party of the United States, a rule requiring the determination of a
presidential nominee by the votes of two-thirds of delegates to the
Democratic National Convention was adopted at the party's first
presidential nominating convention in
1832. The two-thirds rule gave
southern Democrats a ''de facto'' veto over any presidential nominee after the Civil War, which lasted until the rule was abolished in
1936.
In the
Federalist Papers, Alexander Hamilton and James Madison were critical of supermajority requirements. In Federalist 22, Hamilton wrote that while preventing harmful legislation from being passed, such requirements also prevented beneficial legislation from being passed, and "its real operation is to embarrass the administration, to destroy the energy of government, and to substitute the pleasure, caprice or artifices of an insignificant, turbulent or corrupt junto, to the regular deliberations and decisions of a respectable majority." Hamilton also wrote that such a requirement would encourage "contemptible compromises of the public good". In Federalist 58, Madison wrote that supermajority requirements might help impede the passage of "hasty and partial measures", but "
all cases where justice or the general good might require new laws to be passed, or active measures to be pursued, the fundamental principle of free government would be reversed. It would be no longer the majority that would rule; the power would be transferred to the minority." Madison also wrote that such requirements would encourage

Common supermajorities
A
majority vote, or more than half the votes cast, is a common
voting basis. Instead of the basis of a majority, a supermajority can be specified using any
fraction

which is greater than
one-half. Common supermajorities include three-fifths (60%), two-thirds (66.666...%), and three-quarters (75%). In most cases, if the supermajority fraction or percentage of votes yields a non-
whole number, it is
rounded to the next higher whole number.
Two-thirds
A two-thirds vote, when unqualified, means two-thirds or more of the votes cast.
[.p] This voting basis is equivalent to the number of votes in favor being at least twice the number of votes against.
Abstentions and absences may be excluded when calculating a two-thirds vote.
The two-thirds requirement can be qualified to include the entire membership of a body instead of only those present and voting, but such a requirement must be explicitly stated (such as "two-thirds of those members duly elected and sworn").
In this case, abstentions and absences count as votes against the proposal. Alternatively, the voting requirement could be specified as "two-thirds of those present", which has the effect of counting abstentions but not absences as votes against the proposal.
For example, if there are 100 eligible voters, 67 votes are required for a supermajority (two-thirds of 100, rounded up). However, if two voters abstain or are absent, the total decreases to 98, and the required votes for a supermajority drops to 66 (two-thirds of 98, rounded up).
In Italy, between 1948 and 1993, the
Senate was divided into a number of single-seat constituencies, where, to get elected in a FPTP vote, a two-thirds majority of votes was required. Usually, it was attainable only for the

South Tyrol, thus most other Senators were still elected proportionally in regional constituencies, after being grouped in party lists.
Three-fifths, or 60 percent
Another type of supermajority is three-fifths (60 percent). This requirement could also be qualified to include the entire membership or to include those present.
In 2006, the
Constitution of Florida was amended to require a 60% majority to pass new constitutional amendments by popular vote.

Different amendment procedures apply to different parts of the Constitution. Most of the Articles of the Constitution may be amended by a bill enacted by Parliament if there is at least a supermajority of two-thirds of all elected MPs voting in favour of the bill during its Second and Third Readings in Parliament.

However, the ruling
People's Action Party (PAP) has commanded a majority of more than two-thirds of the seats in Parliament since 1968. Thus, the more stringent amendment requirement has not imposed any major limitation on Parliament's ability to amend the Constitution.

provided that the
United Kingdom House of Commons could be dissolved and an election held before the expiry of its 5-year term by a vote of two-thirds of the membership of the House of Commons. The Act also provided that Parliament could alternatively be dissolved if the House of Commons passed a motion of no-confidence in the government and no new government were to win a motion of confidence within two weeks of the original vote of no-confidence.
The two-thirds supermajority provision for an early dissolution and election was triggered only once, resulting in the

The 2017 United Kingdom general election was held on Thursday 8 June 2017, two years after the 2015 United Kingdom general election, previous general election in 2015; it was the first since 1992 United Kingdom general election, 1992 to be held ...

2015 had occurred due to the natural expiry of the 5-year term of the House of Commons.
Parliamentary supremacy meant that theoretically the Act could be circumvented by a government with a majority that wanted to bypass the requirement for a two-thirds vote by passing an act that stated, "Notwithstanding the Fixed-term Parliaments Act 2011, a general election will be called on DATE".

, at least nine of the Security Council's 15 members (i.e., a three-fifths supermajority) must vote in favor of a draft resolution in order to achieve passage. Specifying the fixed membership has the effect of making abstentions count as votes against—absences are not normal but would be treated the same way.

Permanent members who do not support a measure but are unwilling to be seen to block it against the wishes of the majority of the council, tend to abstain; abstentions by veto powers are generally seen by close observers of the UN as the equivalent of not vetoing votes against and have the same impact on the decision of the Security Council.

or a convention called by Congress on application of two-thirds (currently 34) of the states. Once proposed, the amendment must be ratified by three-quarters (currently 38) of the states (either through the state legislatures, or ratification conventions, whichever "mode of ratification" Congress selects).
Congress may pass bills by simple majority votes. If the president vetoes a bill, Congress may override the veto by a two-thirds supermajority of both houses.
A treaty must be ratified by a two-thirds supermajority of the Senate to enter into force and effect.
Section 4 of the Twenty-fifth Amendment to the United States Constitution

gives Congress a role to play in the event of a presidential disability. If the vice president and a majority of the president's cabinet declare that the president is unable to serve in that role, the vice president becomes acting president. Within 21 days of such a declaration (or, if Congress is in recess when a president is disabled, 21 days after Congress reconvenes), Congress must vote by two-thirds supermajorities to continue the disability declaration; otherwise, such declaration expires after the 21 days and the president would at that time "resume" discharging all the powers and duties of the office. , Section 4 has never been invoked.
The House may, by a simple majority vote, impeach a federal official (such as, but not limited to, the president, vice president, or a federal judge). Removal from office requires a two-thirds supermajority of the Senate. In 1842, the House failed to impeach president John Tyler. In 1868, the Senate fell one vote short of removing president Andrew Johnson following his impeachment. In 1999, efforts to remove Bill Clinton
William Jefferson Clinton (né Blythe III; born August 19, 1946) is an American politician and lawyer who was the 42nd president of the United States from 1993 to 2001. A member of the Democratic Party (United States), Democratic Party, ...

was impeached for a second time during his first term and subsequently acquitted. Each chamber may expel one of its own members by a two-thirds supermajority vote; this last happened when the House expelled George Santos in 2023.
The 14th Amendment (section 3) bars a person from federal or state office if, after having previously taken an oath to support the Constitution as a federal or state officer, "''shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof''". However, both the House and Senate may jointly override this restriction with a two-thirds supermajority vote each.
A two-thirds supermajority in the Senate is 67 out of 100 senators, while a two-thirds supermajority in the House is 290 out of 435 representatives. However, since many votes take place without every seat in the House filled and representatives participating, it does not often require 67 senators or 290 representatives to achieve this supermajority.
Apart from these constitutional requirements, a Senate rule (except in cases covered by the nuclear option
In the United States Senate, the nuclear option is a Parliamentary procedure, legislative procedure that allows the Senate to override a standing rule by a simple majority, avoiding the two-thirds supermajority normally required to invoke clot ...
, or of a rule change) requires an absolute supermajority of three-fifths to move to a vote through a cloture motion, which closes debate on a bill or nomination, thus ending a filibuster by a minority of members. In current practice, the mere threat of a filibuster prevents passing almost any measure that has less than three-fifths agreement in the Senate, 60 of the 100 senators if every seat is filled.
State government
For state legislatures in the United States, '' Mason's Manual'' says, "A deliberative body cannot by its own act or rule require a two-thirds vote to take any action where the constitution or controlling authority requires only a majority vote. To require a two-thirds vote, for example, to take any action would be to give to any number more than one-third of the members the power to defeat the action and amount to a delegation of the powers of the body to a minority." Some states require a supermajority for passage of a constitutional amendment or statutory initiative.
Many state constitutions allow or require amendments to their own constitutions to be proposed by supermajorities of the state legislature; these amendments must usually be approved by the voters at one or more subsequent elections. Michigan, for instance, allows the Legislature to propose an amendment to the Michigan Constitution; it must then be ratified by the voters at the next general election (unless a special election is called).

One common provision of so-called " taxpayer bill of rights" laws (either in state statutes or state constitutions) is requirement of a supermajority vote in the state legislature to increase taxes. The National Conference of State Legislatures reported in 2010 that fifteen states required a supermajority vote (either a three-fifths, two-thirds or three-quarters majority vote in both chambers) to pass some or all tax increases.
Supermajority requirements for tax increases have been criticized as "deeply flawed" by a report by the progressive Center on Budget and Policy Priorities because such requirements empower a minority of legislators, making it difficult to close tax loopholes or fund transportation infrastructure
