This episode traces the filibuster from its roots to its modern forms. The word descends from the Dutch vrijbuiter and Spanish filibustero, meaning freebooter or plunderer, and was applied in the 1800s to American adventurers such as William Walker before it came to mean legislative obstruction. In 60 BCE Cato the Younger talked until dusk to block Julius Caesar’s request to run for consul in absentia, forcing Caesar to give up his triumph. In 59 BCE Caesar had Cato arrested mid speech during a land bill debate, released him when senators walked out, and took the bill to a popular assembly instead. Later cases include Roseller Lim’s 18 hour stand in the Philippine Senate in 1963 and Texas state senator Bill Meier’s 43 hours in 1977.

When speaking limits arrived, opponents turned to paperwork. French lawmakers filed 137,449 amendments in 2006 against the privatization of Gaz de France, and Hong Kong lawmakers filed 1.9 million in 2013. In the U.S. Senate, the filibuster traces to 1806, when the chamber dropped its previous question motion on Aaron Burr’s advice, and it was first used in 1837. Today ending debate takes 60 votes, filibusters are often just a notice to leadership, and both parties have used the nuclear option on nominations. The episode sets out the arguments of defenders who call the filibuster the soul of the Senate and critics who say it lets a minority block most legislation.

• Lim was stalling for colleague Alejandro Almendras, who arrived and voted for Ferdinand Marcos anyway.
• Meier wore a catheter and collection bag to hold the floor without a restroom break.
• In 1997 Ontario’s New Democrats used mail merge to file 11,500 amendments seeking hearings for individual Toronto streets, and one passed by mistake.
• Jacob Rees-Mogg proposed in 2012 that Somerset get its own time zone 15 minutes behind London.
• Hakeem Jeffries used the House magic minute in 2025 to speak for 8 hours and 44 minutes.
