In re Kent County Adequate Public Facilities Ordinances Litigation, 2007 WL 2875204 (Del. Ch. Sept. 26, 2007), read opinion here. This Chancery Court decision explains the reasoning for an order that certified an interlocutory appeal, and addresses the first leg (at the trial court level) of an interlocutory appeal of the denial of a motion for preliminary injunction, based on Supreme Court Rule 42.  At footnote 9, the Chancery Court also compared Supreme Court Rule 42(b) with Supreme Court Rule 41(b), and concluded that the reference in Rule 42(b) to the criteria of Rule 41(b) did not include the introductory language in 41(b).
