Here is an explanation for you from the web site below (Things that are "not" in the constitution). Notice that there is no specific mention of a right to privacy in the constitution and that it mostly came from the courts. A right to privacy that is implied is not the same as a specific right to privacy. I should also mention that I am not against a "right to privacy". Just when it is misused.The right to privacy
The Constitution does not specifically mention a right to privacy. However, Supreme Court decisions over the years have established that the right to privacy is a basic human right, and as such is protected by virtue of the 9th Amendment. The right to privacy has come to the public's attention via several controversial Supreme Court rulings, including several dealing with contraception (the Griswold and Eisenstadt cases), interracial marriage (the Loving case), and abortion (the well-known Roe v. Wade case). In addition, it is said that a right to privacy is inherent in many of the amendments in the Bill of Rights, such as the 3rd, the 4th's search and seizure limits, and the 5th's self- incrimination limit.
