But in the mid-20th century, obstruction was the last weapon of Southern Democrats, struggling to maintain segregation and Jim Crow practices in their states. He filled or watered down various civil rights laws until 1964, when a coalition of Republicans and Democrats from outside the South mustered the two-thirds majority needed to break it. This enabled the Civil Rights Act of 1964 and the Voting Rights Act of 1965. While pronunciation is the most common form of filibuster in the Senate, there are other ways to delay and kill bills. Since the Senate usually conducts its business unanimously, a Member may cause at least some delay by opposing the motion. In some cases, such as when a bill or resolution is considered on the day it is introduced or tabled by the House, the delay can be up to one day.  However, since this is a legislative day and not a calendar day, the majority can mitigate it by a short postponement.  The only official rule that can put an end to a filibuster is the second paragraph of rule XXII, also known as the rule of clature. Cato used obstruction again in 59 BC. AD in response to an agrarian reform law sponsored by Caesar, the consul at the time.  When Cato was to speak during the debate, he began one of his characteristic long speeches. Caesar, who was to pass the law before his co-consul Marcus Calpurnius Bibulus took possession of the Fasces at the end of the month, immediately recognized Cato`s intention and ordered the lictors to imprison him for the rest of the day.
This decision was unpopular with many senators and Caesar, realizing his mistake, soon ordered Cato`s release. The day was lost without the Senate ever being able to vote on a motion to support the bill, but Caesar eventually bypassed Cato`s opposition by taking the measure to the tribal convention, where it passed. The evolution of majorities of both parties – and their supporters – was often frustrated because key political priorities articulated in political campaigns could not be adopted after an election. Although the Democratic Party had a clear majority in the 111th Congress, the „public option” provision of the Affordable Care Act was removed because one senator — Joe Lieberman of Connecticut — threatened to filibuster the law if it remained. Proponents of changing the so-called filibuster only serve to force Democrats to make concessions to Republicans who are not at all interested in negotiating. The first incident of obstruction of the Legislative Council (LegCo) after the transfer occurred during the second reading of the Municipal Service Delivery (Reorganization) Act in 1999, which sought to dissolve the partially elected City Council and the Regional Council. Since the absence of some pro-establishment lawmakers would mean insufficient support for the passage of the bill, the pro-establishment camp as well as Michael Suen, then secretary of constitutional affairs, filibustered, the vote on the bill was postponed until the next day, and absentee ballots were able to vote. Although the obstruction was criticized by the pro-democracy camp, Lau Kong-wah of the Democratic Alliance for the Betterment and Progress of Hong Kong (DAB) defended their actions by saying, „This (obstruction) is perfectly acceptable in a parliamentary assembly.”  Senate leaders no longer needed filibustering senators to speak for hours, so that one would remember the drama of night sittings, which could last for weeks. Senators of both parties have adopted obstruction, or the threat of obstruction, as another tool.
In the Southern Rhodesian Legislative Assembly, independent member Ahrn Palley organized the Legislative Assembly on 22 September. In November 1960, a similar filibuster against the Law and Order Act, although it took the form of a long series of amendments to the bill and thus consisted of several individual speeches interspersed with comments from other members. Palley held the meeting from 8:00 p.m. to 12:30 p.m. the next day. Therefore, on many matters in the Senate, debate can only be interrupted if at least 60 senators support it. (However, this is not universally true, and we`ll see some consistent counterexamples below.) While Senate rules still require only a simple majority to pass a bill, several procedural steps along the way require a 60-vote supermajority to end debate on bills. In the end, the government did not have to use any of these procedures.
When the parliamentary debate began, the left-wing opposition withdrew all the amendments so that the vote could continue. The filibuster was cancelled because opposition to the privatization of Gaz de France seemed to lack popular support. It also seemed that this privatization law could be used as a political argument by the left in the 2007 presidential election. Nicolas Sarkozy, president of the Union for a Popular Movement (UMP), interior minister, former finance minister and future president, had previously promised that the French government`s share in Gaz de France would never fall below 70%. Manchin left little room to change his mind, to get rid of the obstruction. Critics of the modern filibuster have argued that the maneuver undermines the Senate as a governing body and its reputation as a consensus chamber. The mere threat of obstruction silences debate and removes incentives to compromise. In 1917, the Senate passed Article XXII, or the rule of closure, which broke a two-thirds majority obstruction. In 1975, the Senate reduced the requirement to 60 votes, becoming the minimum for passing a bill.
Both houses of the Australian Parliament have strictly enforced rules on how long members are allowed to speak, so filibustering is generally not possible, although some state parliaments do not.   The abolition of filibuster could be a major campaigner. But at the end of the day, decisions about Senate rules are the responsibility of the Senate, not the presidential nominees. But creating an exception requires a majority of votes to change the rules. And the Democrats in the Senate don`t have that right now. This winter, Democrats tried — and failed — to create a similar fallout from the right to vote, adopt a national standard on how to vote, and override restrictions on red states. Even if closure has been called, in most cases debate can continue for another 30 hours, and most bills are subject to two or three filibusters before the Senate can vote on its passage (first on a motion to study the law, and then perhaps on an alternative amendment to the law). and finally on the bill itself).  Even bills supported by 60 or more senators (as well as appointments) can therefore be delayed by obstruction.
