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 235 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“effectively preclude the jury from considering the issue of malice aforethought in all cases wherein homicide has been committed as a result of a felonious assaulta category which includes the great majority of all homicides. This kind of bootstrapping finds support neither in logic nor in law. We therefore hold that a second degree felony-murder instruction may not properly be given when it is based upon a felony which is an integral part of the homicide and which the evidence produced by the prosecution shows to be an offense included in fact within the offense charged.”
