Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 71 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
““Courts of Justice agree that no statute, however positive in its terms, is to be construed as designed to interfere with existing contracts, rights of action, or with vested rights, unless the intention that it shall so operate is expressly declared or is to be necessarily implied, and jiursuaut to that rule courts will apply new statutes only to future cases, unless there is something in the nature of the case or in the language of the new provision which shows that they wore intended to have a retroactive operation. Even though the words of a statute are broad enough in their literal extent to .comprehend existing cases, they must yet be construed as applicable only to cases that may hereafter arise, unless the language employed expresses a contrary intention in unequivocal terms.””
