Remove the subdivision

Warning²Federal courts, Illinois courts21st and 22nd editions

An institution credited as editor is read the way an institutional author is, so a subdivision named behind it stays out of the citation unless it is particularly relevant to the point cited.¹

1. 1R. 15.2(b) Institutional editors; R. 15.1(c) Institutional authors. Tables: T6 Case Names and Institutional Authors in Citations; R. 15.1(e) Abbreviations; R. 15.1(d) Abbreviations.
2. 2A warning: the form is usually wrong under the rule in note 1, and context can justify it.
