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.
““Two requirements are necessary for an appellate court opinion. First, three judges must participate in the decision of every case. 145 Ill. 2d R. 22(c). Second, the concurrence of two judges in the judgment of the court is necessary. 145 Ill. 2d R. 22(c); Ill. Const. 1970, art. VI, §5; 705 ILCS 25/l(d) (West 1994). Absent the concurrence of at least two judges, the appellate court cannot render a valid judgment.” Proctor v. The Upjohn Co., 175 Ill. 2d 394, 396 (1997).”
