The principal purpose of stare decisis is to protect reliance interest and further stability in the law.
Antonin ScaliaJustice White's conclusion is perhaps correct, if one assumes that the task of a court of law is to plumb the intent of the particular Congress that enacted a particular provision. That methodology is not mine nor, I think, the one that courts have traditionally followed. It is our task, as I see it, not to enter the minds of the Members of Congress - who need have nothing in mind in order for their votes to be both lawful and effective - but rather to give fair and reasonable meaning to the text of the United States Code, adopted by various Congresses at various times.
Antonin Scalia[T]he enshrinement of constitutional rights necessarily takes certain policy choices off the table.... Undoubtedly some think that the Second Amendment is outmoded in a society where our standing army is the pride of our Nation, where well-trained police forces provide personal security, and where gun violence is a serious problem. That is perhaps debatable, but what is not debatable is that it is not the role of this Court to pronounce the Second Amendment extinct.
Antonin ScaliaMore importantly, the Court forgets that ours is a government of laws and not of men. That means we are governed by the terms of our laws, not by the unenacted will of our lawmakers. 'If Congress enacted into law something different from what it intended, then it should amend the statute to conform to its intent.' In the meantime, this Court 'has no roving license ... to disregard clear language simply on the view that ... Congress 'must have intended' something broader.
