Your "Right to Privacy": What Do the Constitution and the Law Say?

You've probably heard the phrase "Life, Liberty and the pursuit of Happiness" from the U.S. Declaration of Independence. While not legally binding, this motto is the cornerstone of the United States government and the Constitution.

This, of course, isn't the only such motto.

The French have "Liberte, Egalite, Fraternite" (Liberty, Equality, Fraternity), the British
"Peace, Order and Good Government", the Germans "Eingkeit, und Recht und Freiheit" (Unity, Justice, Liberty).

Now, if you're reading these mottos carefully, you're probably noticing one thing.

None of them really mention the right to privacy excplicitly.

So what does the law and, specifically, the U.S. Constitution say about it?

What is the Right to Privacy?

Before we get into the right to privacy in the Constitution and different laws, it's important to define it first to have a concept.

The right to privacy is an individual's right to be left alone and for his or her private information to be free from public inspection.

This right is typically protected by statutory law such as the Federal Trade Commission (FTC) or the Health Information Portability and Accountability Act (HIPAA), however, it is nowhere explicitly mentioned in the U.S. Constitution.

The Right to Privacy in the Constitution and the Supreme Court Interpretation


That said, while there is no right to privacy Amendment per se, different parts of the Constitution still offer privacy protection to varying degrees.

In particular:

  1. The First Amendment - Privacy of beliefs.
  2. The Third Amendment - Privacy of one's home against its use for housing soldiers in times of peace.
  3. The Fourth Amendment - Privacy against unreasonable searches.
  4. The Fifth Amendment - Privacy of personal information through protection against self-incrimination.
  5. The Ninth Amendment - Interpreted to justify a broad reading of the Bill of Rights to protect an individual's right to privacy in ways that Amendments 1-8 do not.
  6. The Fourteenth Amendment - Prevents any state from making a law that contravenes with Amendments 1-13 regarding the protection of personal autonomy. I.E. state laws that in any way violate the person's freedom of speech, religion, or other parts of their private lives.

Of particular interest, when we talk about the right to privacy in the Constitution is the Due Process Clause.

The Due Process Clause is mentioned in both the Fifth and Fourteenth Amendment and it states:

No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.

In short, the Supreme Court interprets that the Due Process Clause offers constitutional protection in three ways:

  1. Procedural due proces
  2. Substantive due process and
  3. Prohibition against vague laws

How Different Laws Protect the Person's Private Life and the Access to Private Information?


Several laws and acts enable an individual to determine what information about them can be collected and how it can be used.

These laws include:

In addition, it's also important to know the email privacy laws in the workplace and if your boss can read your emails, so be sure to read our article on that as well.


While the right to privacy is never explicitly mentioned as guaranteed in the U.S. Constitution, the legal system recognizes it and the Supreme Court finds that it can be implied from the different amendments including the 1st, 3rd, 4th, 5th, 9th and 14th.

In addition, the civil and the different state laws also work to protect the individual's privacy against government surveillance and governmental intrusion, including unreasonable searches and seizures and against public scrutiny.

Of course, since the right to privacy is, again, not explicitly stated in the constitutional rights, these should be viewed with reasonable expectation.
