We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. --That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.
--Excerpt from the Declaration of Independence
The legal history of the United States largely stems from the hierarchy of rights developed in the opening statements of the Declaration of Independence. It is held that Life is the single overriding right that must first be attended to, even before Liberty and the pursuit of Happiness. Therefore, no action may be taken, nor law written, that places one's right to Liberty above the right to Life. By the same token, no action may be taken that would place one's pursuit of Happiness above the right to Life or Liberty. Note that this indicates that one may not even pursue Happiness at the expense of his own right to Life or Liberty. Further, one may not strive to hold his own right to Life above another's right to Life, Liberty above another's Liberty, nor pursuit of Happiness over another's pursuit of Happiness. As Life is the overriding right, it may not be infringed on by any man, since it is endowed by the Creator. Liberty and the pursuit of Happiness may only be infringed by government in cases where a person has violated another's right of a higher position in the hierarchical structure of rights. Thus, incarceration - the rescinding of one's right to Liberty - is an allowable recourse if one has violated one of these cardinal rights.
