The Chewbacca defense is a legal strategy used in episode 27 of South Park, "Chef Aid", which premiered on October 7, 1998. The aim of the argument is to deliberately confuse the jury by making use of the fallacy known as ignoratio elenchi (irrelevant conclusion) or a red herring. The concept satirised attorney Johnnie Cochran's closing argument defending O. J. Simpson in his murder trial.
Within the context of the episode, the fictional Cochran begins his argument by stating, incorrectly, that Chewbacca lives on the planet Endor. He goes on to make note of the supposed senselessness of his statement noting "It does not make sense". He then goes further to remark that the entire situation (namely his use of the film Star Wars as evidence in a harassment suit) "does not make sense" either. His closing argument "If Chewbacca lives on Endor, you must acquit" lampoons the real Cochran's "If it doesn't fit, you must acquit".
In the episode, Chef contacts a "major record company" executive, seeking only to have his name credited as the composer of "Stinky Britches". Chef's claim is substantiated by a 20‑year-old recording of Chef performing the song.
The record company refuses, and furthermore hires Johnnie Cochran, who files a lawsuit against Chef for harassment. In court, Cochran resorts to his "famous" Chewbacca defense, which he "used during the Simpson trial", according to Chef's lawyer, Gerald Broflovski. Although Broflovski uses logic, reasoning and the fact that Chef properly copyrighted his work, Cochran counters with the following:
- ...ladies and gentlemen of this supposed jury, I have one final thing I want you to consider. Ladies and gentlemen, this is Chewbacca. Chewbacca is a Wookiee from the planet Kashyyyk. But Chewbacca lives on the planet Endor. Now think about it; that does not make sense!
- Gerald Broflovski
- Damn it! ... He's using the Chewbacca defense!
- Why would a Wookiee, an 8-foot-tall Wookiee, want to live on Endor, with a bunch of 2-foot-tall Ewoks? That does not make sense! But more important, you have to ask yourself: What does this have to do with this case? Nothing. Ladies and gentlemen, it has nothing to do with this case! It does not make sense! Look at me. I'm a lawyer defending a major record company, and I'm talkin' about Chewbacca! Does that make sense? Ladies and gentlemen, I am not making any sense! None of this makes sense! And so you have to remember, when you're in that jury room deliberatin' and conjugatin' the Emancipation Proclamation, does it make sense? No! Ladies and gentlemen of this supposed jury, it does not make sense! If Chewbacca lives on Endor, you must acquit! The defense rests.
This penultimate statement is a parody of Cochran's closing arguments in the O. J. Simpson murder case where he states to the jury "If it doesn't fit, you must acquit!" in reference to an earlier point in the trial when prosecutor Christopher Darden asked Simpson to try on a pair of bloody leather gloves found at the murder scene and the gloves turned out to be too small for Simpson to put on easily over latex surgical gloves Simpson put on just before.
Similarly, in the episode, Cochran's defense is successful and the jury finds Chef guilty of "harassing a major record label", after which the judge sets his punishment as either a $2 million fine to be paid within 24 hours or, failing that, four years in prison (the judge initially sentences him to eight million years before being corrected by a court officer).
Ultimately, a "Chef Aid" benefit concert is organized to raise money for Chef to hire Cochran for his own lawsuit against the record company. At the concert, Cochran experiences a change of heart and offers to represent Chef pro bono. He again successfully uses the Chewbacca defense, this time to defeat the record company and force them to acknowledge Chef's authorship of their song. In the second use of the Chewbacca defense, he ends by taking out a monkey puppet and shouting, "Here, look at the monkey. Look at the silly monkey!" causing a juror's head to explode.
Criminologist Dr. Thomas O'Connor says that when DNA evidence shows "inclusion", that is, does not exonerate a client by exclusion from the DNA sample provided, "About the only thing you can do is attack the lab for its (lack of) quality assurance and proficiency testing, or use a 'Chewbacca defense' … and try to razzle-dazzle the jury about how complex and complicated the other side's evidence or probability estimates are." Forensic scientist Erin Kenneally has argued that court challenges to digital evidence frequently use the Chewbacca defense by presenting multiple alternative explanations of forensic evidence obtained from computers and Internet providers to raise the reasonable doubt understood by a jury. Kenneally also provides methods that can be used to rebut a Chewbacca defense. Kenneally and colleague Anjali Swienton have presented this topic before the Florida State Court System and at the 2005 American Academy of Forensic Sciences annual meeting.
The term has also seen use in political commentary; Ellis Weiner wrote in The Huffington Post that Dinesh D'Souza was using the Chewbacca defense in criticism of then-new Speaker of the House Nancy Pelosi, defining it as when "someone asserts his claim by saying something so patently nonsensical that the listener's brain shuts down completely".
The term was used by Paul Krugman, who wrote in The New York Times that John Taylor is using the Chewbacca defense as a seemingly last option for defending his hawkish monetary policy position, after years of publicly stating that "quantitative easing would lead to a major acceleration of inflation."
