If a person has a reasonable expectation of privacy, what legal concept do they possess?

When a person has a reasonable expectation of privacy, they possess the legal concept known as standing. Standing is the ability of an individual to demonstrate that they have a sufficient connection to and harm from the law or action that they are challenging in court. A reasonable expectation of privacy implies that an individual has acknowledged rights regarding their personal space, belongings, or communications, and thus can challenge government actions that may infringe upon those rights.

This legal concept allows individuals to sue if their privacy rights have been violated, such as in cases involving unlawful searches and seizures. The determination of standing often includes whether the individual had a subjective expectation of privacy that society recognizes as reasonable, reinforcing their ability to claim a legal response if that privacy is compromised.
