In an abstract sense, justice, ethical correctness, or harmony with the RULES OF LAW or the principles of morals. In a concrete legal sense, a power, privilege, demand, or claim possessed by a particular person by virtue of law.
Each legal right that an individual possesses relates to a corresponding legal duty imposed on another. For example, when a person owns a home and property, he has the right to possess and enjoy it free from the interference of others, who are under a corresponding duty not to interfere with the owner's rights by trespassing on the property or breaking into the home.
In CONSTITUTIONAL LAW, rights are classified as natural, civil, and political. Natural rights are those that are believed to grow out of the nature of the individual human being and depend on her personality, such as the rights to life, liberty, privacy, and the pursuit of happiness.
CIVIL RIGHTS are those that belong to every citizen of the state, and are not connected with the organization or administration of government. They include the rights of property, marriage, protection by law, freedom to contract, trial by jury, and the like. These rights are capable of being enforced or redressed in a civil action in a court.
Political rights entail the power to participate directly or indirectly in the establishment or administration of government, such as the right of citizenship, the right to vote, and the right to hold public office.
