Final answer:
The right to be left alone, have control over personal possessions, and not be observed without consent is known as the right to privacy.
Step-by-step explanation:
The right that means the right to be left alone when you want to be, to have control over your personal possessions, and not to be observed without your consent is commonly referred to as the right to privacy.
Privacy is a fundamental aspect of civil liberty and allows for personal autonomy. It includes the ability to make personal decisions without interference, such as decisions about having children, choosing whom to marry, and making choices about clothing, education, career, and religious beliefs. Privacy is a space separate from public life, where individuals can think, speak, and behave without being monitored or surveilled.
Some important court cases, such as Pierce v. Society of Sisters, Griswold v. Connecticut, Roe v. Wade, and Lawrence v. Texas, have recognized and upheld the right to privacy, specifically in relation to personal decisions concerning education, sexuality, and reproductive choices.
