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 30 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
““(a) A person who kills an individual without lawful justification commits voluntary manslaughter if at the time of the killing he is acting under a sudden and intense passion resulting from serious provocation by: (1) The individual killed, or (2) Another whom the offender endeavors to kill, but he negligently or accidentally causes the death of the individual killed. Serious provocation is conduct sufficient to excite an intense passion in a reasonable person.””
