The First Amendment guarantees the right to free speech, one of the most fundamental liberties in the United States. However, that right is not absolute. In Colorado and across the nation, there are limits to what you can say when your words cause harm to another person’s reputation. Understanding where free speech ends and defamation begins can help you protect your rights while avoiding costly legal consequences.
The First Amendment to the U.S. Constitution protects the freedom of speech, expression, religion, press, and assembly. It allows people to share ideas, criticize the government, and express opinions without fear of censorship. However, the First Amendment does not protect all forms of speech. Certain categories of expression, such as true threats, incitement to violence, and defamation, can lead to legal action.
Colorado courts recognize that free speech is vital to democracy, but they also uphold the right of individuals to protect their reputations. This balance is where defamation law comes into play. When someone makes a false statement of fact that damages another person’s reputation, they may be held legally responsible for defamation, even if they claim they were exercising their right to free speech.
Defamation is a false statement of fact that causes harm to someone’s reputation. In Colorado, defamation can take two forms: libel and slander. Libel refers to written or published defamation, while slander refers to spoken defamation. To prove defamation, the injured person (the plaintiff) must typically show the following elements:
Opinions, by contrast, are generally protected under the First Amendment. You can say, “I think that restaurant has bad food,” because that is a subjective statement. But saying, “That restaurant serves expired meat,” if untrue, could qualify as defamation because it is a specific factual claim that can be proven false.
The line between opinion and fact can sometimes be blurry. That is why consulting with an attorney experienced in First Amendment law is critical if you believe you have been defamed or are accused of making defamatory statements.
Not all defamation cases are treated equally under the law. The U.S. Supreme Court has made it harder for public figures and government officials to win defamation lawsuits. This higher standard protects open discussion and criticism of those in positions of power.
In the landmark case New York Times Co. v. Sullivan (1964), the Court held that public figures must prove “actual malice” to win a defamation claim. This means they must show the false statement was made knowingly or with reckless disregard for the truth. Private individuals, on the other hand, only need to prove that the statement was made negligently, meaning the person who made it failed to exercise reasonable care in verifying its accuracy.
For example, if a news outlet publishes a false story about a local celebrity without confirming the facts, that person might need to show the publication acted with reckless disregard for the truth. But if the same outlet spreads false rumors about a private citizen, the lower negligence standard would apply.

In today’s digital world, defamation often happens online. Posts on platforms like Facebook, X (formerly Twitter), or Instagram can reach thousands of people instantly. Because of that, a single false statement can cause serious and lasting damage to someone’s reputation, business, or career.
Many people believe they are protected by free speech when posting online, but the same defamation rules apply. If you share false information about someone, even in a private group or comment section, you can still face legal consequences. Similarly, repeating or reposting defamatory content from others can expose you to liability if you help spread the falsehood further.
Colorado courts treat online defamation seriously, and the rise of social media has led to an increase in lawsuits based on digital communications. Even anonymous posters can sometimes be identified through subpoenas and digital evidence, making accountability a real possibility.
If someone has made false statements about you that are harming your personal or professional reputation, it is important to act quickly. Evidence in defamation cases can disappear fast as posts are deleted or accounts are taken down. Preserve screenshots, messages, and any other documentation that shows what was said and where it was published.
An experienced attorney can help you determine whether the statements meet the legal definition of defamation and whether pursuing a lawsuit is in your best interest. In some cases, your lawyer may be able to resolve the issue through a retraction, correction, or settlement before litigation becomes necessary.
On the other hand, if you have been accused of defamation for exercising your right to free speech, you also have legal protections. An attorney can evaluate whether your statements were protected opinions, whether the alleged victim is a public figure, and whether the claim is an attempt to silence or intimidate you.
