9 Largest Class Action Settlements Ever Reached


Class-action lawsuits are the headline-grabbing legal actions that can provide a huge windfall for the attorneys and plaintiffs. It’s rare for class-action suits to actually go to trial. Most often, the two sides meet and attempt to negotiate a settlement. The settlements are usually for far less money than a potential court decision would provide the plaintiffs. Also, the defendants in the suits don’t have to admit they did anything wrong. Class-action suits often yield settlements of over $1 million; however, some cases are settled for massive amounts as we will see below.

In 2010, the FBI raided the offices of several auto parts manufacturers, uncovering a price-fixing scheme that artificially kept the prices of auto parts high. The companies involved allegedly conspired and agreed to this scheme, defrauding auto dealers, mechanics and consumers. There were 160 companies involved in the scheme. The fraud raised the price of vehicles and of replacement parts.

The attorneys representing the plaintiffs reached an initial agreement with the defendants of over $640 million in 2016, but later reached a new agreement as more plaintiffs were included in the class action.

In 2010, Syngenta, an agricultural seed developer, introduced a corn seed that would be more resistant to insects. The manufacturer promoted and marketed the seed as being ready to plant and yield corn that overseas markets would have no issue with. However, China, a major trade partner with the American agricultural industry, rejected the seed because it had not yet been approved by the government. So then, China refused entire shipments that might contain the banned seed because of a “zero-tolerance” policy.

Having lost millions of dollars, several corn growers and exporters filed suit against Syngenta in 2013. In 2018, a court approved a settlement of the lawsuit.

American agri-business lost $2.9 billion because of China’s zero-tolerance policy.

In 2008, SCANA began construction on two nuclear power plants in South Carolina. The company portrayed the construction as trouble-free and proceeding on time. The South Carolina Electric & Gas (SCE&G) company charged its customers $30 on average for the construction costs, included in their monthly bills. The shareholders of SCANA relied on the company reports regarding the plants’ construction progress and bought shares.

By 2013, it became public knowledge that the plans to build the plants were in trouble. In 2017, the construction company building the plant went bankrupt. The companies involved in building the plant had wasted billions of taxpayer dollars on the plant.

The plaintiffs sued in 2017 and reached the multi-billion dollar settlement agreement in 2018.

In the early 1970s, some women reported illnesses after they received silicone breast implants. Their doctors linked the illness, autoimmune disease, to ruptures in the implants. Several women filed product liability lawsuits over the years against Dow Chemical and Dow Corning. The women alleged that the implants were inherently unsafe and that they were in fact injured from using them.

There were so many suits that Dow Corning felt it necessary for bankruptcy in 1995. The company proposed to settle with 170,000 women affected by the suit and promised to pay for implant removal for tens of thousands more. The women received about $31,000 per person.

Did You Know?

No scientific study showed a definitive link between autoimmune disease and the silicone despite the thousands of women who only fell ill after getting the implant.

In 2005, several groups representing retail stores across the United States sued Visa, Master Card and banks issuing credit cards because they were being charged “swipe fees.” The merchants were charged by the banks whenever a customer paid with a credit card. They were not allowed to inform customers they could pay another way and the payments were allegedly illegally inflated.

The groups reached a settlement in 2015. However, some businesses didn’t find the terms agreeable and dropped out. A judge invalidated the settlement in 2017. The parties reached a new agreement later with additional class members that pushed the total settlement to $6 billion.

As a result of the litigation, stores in some US states may require consumers to pay a portion of the swipe fee.
