Katz v. United States · ¶48

Since I see no way in which the words of the Fourth Amendment can be construed to apply to eavesdropping, that closes the matter for me. In interpreting the Bill of Rights, I willingly go as far as a liberal construction of the language takes me, but I simply cannot in good conscience give a meaning to words which they have never before been thought to have and which they certainly do not have in common ordinary usage. I will not distort the words of the Amendment in order to “keep the Constitution up to date” or “to bring it into harmony with the times.” It was never meant that this Court have such power, which in effect would make us a continuously functioning constitutional convention.
