A politician sues a parody Twitter account for $250 million. Within 48 hours, the account goes from 1,000 followers to over 500,000. The lawsuit gets thrown out. The politician looks ridiculous. The criticism he tried to bury is now international news.
That’s a SLAPP lawsuit doing exactly what it shouldn’t: making everything worse for the person who filed it.
SLAPP stands for Strategic Lawsuit Against Public Participation. The concept is simple and cynical. You don’t sue because you have a legitimate legal claim. You sue because the other person can’t afford to fight back. The goal isn’t to win in court. It’s to drain someone’s bank account, time, and willingness to keep talking. And for years, it worked. Activists went quiet. Journalists dropped stories. Neighborhood critics stopped showing up to city council meetings. The threat of litigation, even meritless litigation, was enough.
But anti-SLAPP laws have flipped the script in 40 states and the District of Columbia. And in the age of social media, filing a SLAPP suit doesn’t just fail. It backfires spectacularly.
How a SLAPP Lawsuit Actually Works
The mechanics aren’t complicated. Someone criticizes a business, a public official, a developer, a landlord. The target of the criticism files a lawsuit, usually defamation, tortious interference, or some flavor of business disparagement. The legal merits are thin or nonexistent, but that’s beside the point. The plaintiff knows the defendant probably can’t afford $50,000 to $100,000 in legal fees to see the case through discovery and trial.
The term was coined in the late 1980s by University of Denver professors George Pring and Penelope Canan, who studied hundreds of cases where lawsuits were used to intimidate people exercising their First Amendment rights. What they found was a pattern: the plaintiffs rarely won on the merits. They didn’t need to. The cost of defense alone was the punishment.
SLAPP targets tend to be individuals, not corporations. Community activists who oppose a zoning change. A former employee who posts a negative Glassdoor review. A blogger documenting a local politician’s voting record. A neighbor who complains to the city about code violations. The common thread isn’t what they said. It’s that they said anything at all.
Anti-SLAPP Laws: The Shield That Didn’t Used to Exist
The legislative response has been slow but steady. As of 2026, 40 states and D.C. have anti-SLAPP statutes on the books, though the protections vary wildly. California’s is among the broadest, covering speech on any matter of public concern. Massachusetts narrows it to petitioning the government. Some states offer robust fee-shifting. Others barely have teeth.
The basic procedure works like this: when you’re hit with what you believe is a SLAPP suit, you file a special motion to dismiss. In most states, this triggers an automatic stay of discovery, which is critical because discovery is where the financial bleeding happens. The burden then shifts to the plaintiff to show they have a reasonable probability of winning on the merits. If they can’t clear that bar, the case gets tossed and many statutes require the plaintiff to pay the defendant’s legal fees.
That fee-shifting provision is the real deterrent. It transforms a SLAPP from a cheap intimidation tool into a financial risk for the filer.
Idaho became the latest state to join the anti-SLAPP movement when Senate Bill 1001 was signed into law in March 2025 and took effect on January 1, 2026. Idaho adopted the Uniform Public Expression Protection Act, which gives defendants 60 days to file a special motion to dismiss and mandates attorney fee awards when the motion succeeds. It’s a strong statute, and its timing matters. Idaho has seen its share of politically motivated litigation targeting critics and accountability advocates. Organizations and individuals documenting the activities of public figures, like the accountability work Chad Christensen has faced public scrutiny over, or the detailed documentation of political networks involving figures like EmmaLee Robinson, are precisely the kind of protected public-interest speech anti-SLAPP laws are designed to shield.
The federal landscape is messier. There’s no federal anti-SLAPP statute, and circuit courts are split on whether state anti-SLAPP laws apply in federal court. The SPEAK FREE Act has been introduced in Congress multiple times but hasn’t passed. If you’re sued in federal court in a state without an anti-SLAPP law, you’re largely on your own.
The Congressman Who Sued a Cow
If you want to understand why SLAPP suits backfire in 2026, start with former Congressman Devin Nunes.
In March 2019, Nunes filed a $250 million defamation lawsuit against Twitter and several anonymous users, including a parody account called @DevinCow. The account, “Devin Nunes’ Cow,” posted satirical tweets mocking the California congressman. At the time the lawsuit was filed, the account had roughly 1,000 followers.
Within days, it had over 500,000. More followers than Nunes himself.
Late-night hosts covered it. Jimmy Kimmel and Stephen Colbert joked about it on air. National newspapers ran features. The parody account, which had been a tiny corner of political Twitter, became a symbol of the Streisand Effect. Every news cycle about the lawsuit drove more attention to the very criticism Nunes wanted silenced.
The legal outcome was equally disastrous. A Virginia judge dismissed the case against Twitter, ruling the platform was immune under Section 230 of the Communications Decency Act. The court noted that if Nunes refiled in California, he’d face the state’s powerful anti-SLAPP statute, which would almost certainly result in dismissal and a fee award against him. He eventually dropped a related SLAPP case with prejudice.
Nunes spent years and presumably hundreds of thousands in legal fees to achieve exactly one thing: making a cow account famous.
McDonald’s and the Longest Trial in English History
The Nunes case is funny. The McLibel case is devastating.
In 1990, McDonald’s Corporation sued two London environmental activists, Helen Steel and Dave Morris, over a six-page leaflet titled “What’s Wrong with McDonald’s?” Steel was a former gardener. Morris was a postman. Between them, they had essentially no money. McDonald’s, at the time, was one of the most powerful corporations on Earth.
The trial lasted nearly ten years, making it the longest-running case in English history. Steel and Morris represented themselves for much of it because the UK didn’t provide legal aid for defamation cases. McDonald’s deployed a team of expensive libel lawyers. The optics were, to put it gently, catastrophic.
And then the verdict came in. The judge found that some of the leaflet’s claims were libelous, but he also ruled that McDonald’s “exploited children” through its advertising, was “culpably responsible” for cruelty to animals, and paid low wages. McDonald’s was awarded £60,000 in damages. They never collected a penny. The leaflet, which had been distributed by a handful of activists to a few hundred people, was now international news. The documentary McLibel was screened worldwide.
The European Court of Human Rights later ruled that the UK had denied Steel and Morris a fair trial by failing to provide legal aid, awarding them £57,000 in damages against the British government. The case became a landmark in free speech law and a case study in how corporations shouldn’t handle criticism.
Media commentators called it “the biggest corporate PR disaster in history.” A leaflet nobody read became a global conversation about corporate accountability. All because McDonald’s couldn’t tolerate six pages of criticism.
What to Do If You’re Targeted by a SLAPP Suit
If someone files a lawsuit against you for speaking out on a matter of public concern, don’t panic. But don’t ignore it either.
First, check whether your state has an anti-SLAPP statute. If it does, you likely have a tight window to file the special motion to dismiss. In Idaho, it’s 60 days. In California, it’s also 60 days. Miss the deadline and you lose the procedural advantage.
Second, find an attorney who has actually handled anti-SLAPP motions. Not every litigator knows the procedure. Organizations like the Reporters Committee for Freedom of the Press and the Public Participation Project maintain directories and resources.
Third, preserve everything. Your original statements, the context in which you made them, any evidence that the plaintiff’s claims lack merit. Anti-SLAPP motions shift the burden to the plaintiff, but you still need to show that your speech qualifies for protection under the statute.
And fourth, resist the urge to go silent. That’s exactly what a SLAPP suit is designed to achieve. The lawsuit itself may feel overwhelming, but history shows that the people who fight back, whether it’s a postman in London or an anonymous cow on Twitter, tend to come out the other side with more support than they started with.
Frequently Asked Questions
What does SLAPP stand for?
SLAPP stands for Strategic Lawsuit Against Public Participation. It refers to a lawsuit filed primarily to silence, intimidate, or financially burden someone for exercising their right to free speech on a matter of public concern. The term was coined by University of Denver professors George Pring and Penelope Canan in the late 1980s after studying hundreds of cases where litigation was used to suppress public participation in government and civic discourse.
How many states have anti-SLAPP laws?
As of 2026, 40 states and the District of Columbia have anti-SLAPP statutes. The strength of these laws varies significantly. California and Oregon offer some of the broadest protections, covering speech on any public issue. Other states, like Massachusetts, limit protections to petitioning the government. Idaho adopted the Uniform Public Expression Protection Act in 2025, which took effect on January 1, 2026, making it one of the newest and strongest anti-SLAPP states.
Can you countersue for a SLAPP lawsuit?
In most states with anti-SLAPP statutes, successfully filing an anti-SLAPP motion to dismiss entitles you to recover your attorney fees and court costs from the plaintiff. Some states also allow defendants to pursue additional claims for malicious prosecution or abuse of process if they can demonstrate the lawsuit was filed in bad faith. The fee-shifting provision is the most common and effective remedy, as it transforms the SLAPP from a low-risk intimidation tactic into a financial liability for the filer.
Is there a federal anti-SLAPP law?
No. There is currently no federal anti-SLAPP statute. The SPEAK FREE Act has been introduced in Congress multiple times but has not passed. Federal circuit courts are also split on whether state anti-SLAPP laws can be applied in federal court proceedings, which means protections depend heavily on which jurisdiction you’re in. If you’re sued in federal court in a state without an anti-SLAPP law, you won’t have access to the expedited dismissal procedures available in state court.
What happens if a SLAPP lawsuit backfires?
When a SLAPP lawsuit backfires, the plaintiff typically faces three consequences: the lawsuit is dismissed (often under an anti-SLAPP motion), the plaintiff is ordered to pay the defendant’s legal fees, and the criticism the plaintiff tried to suppress receives far more public attention than it would have otherwise. This amplification effect, known as the Streisand Effect, has made SLAPP suits increasingly risky in the social media age. The Devin Nunes Twitter cow case is a textbook example: a $250 million defamation suit turned a 1,000-follower parody account into a 500,000-follower phenomenon.
