What is necessary for establishing a reasonable expectation of privacy according to the Katz Test?

The Katz Test, stemming from the Supreme Court case Katz v. United States, determines the conditions under which individuals have a reasonable expectation of privacy. For an expectation of privacy to be considered reasonable, two key criteria must be met: an actual subjective expectation of privacy and a societal recognition that this expectation is reasonable.

The first part, an actual expectation of privacy, means that the individual believes they have a right to privacy in the specific situation. The second part requires that this expectation is one that society is prepared to recognize as reasonable. For example, people generally have an expectation of privacy in their homes or personal communications, which society agrees should be protected against unwarranted intrusions.

The correct choice effectively captures the essence of these two components, distinguishing it as the foundation for establishing a reasonable expectation of privacy under the Katz Test. Other options, while they relate to privacy and authority, do not encompass the necessary subjective and societal agreement aspects central to the Katz Test.
