MEMORANDUM OPINION AND ORDER
Gallagher Security (U.S.A.), Inc. and Gallagher Group Ltd. (collectively "Gallagher," treated after this sentence as a singular noun purely for convenience) have sought to target for dismissal this action brought against them by GDI, LLC ("GDI"). Those efforts have borne a greater resemblance to skeet shooting than to the proverbial shooting of fish in a barrel, for GDI has presented a constantly moving target -- its most recent submission is the just-filed Sixth Amended Complaint, which has been coupled with its memorandum responding to Gallagher's motion to dismiss GDI's Fourth Amended Complaint.*fn1
Much of GDI's memorandum is devoted to the issue of preclusion stemming from its voluntary dismissal of an Illinois state court action that it had brought against its ex-employee Elliot Rose and into which it had injected one of the Gallagher entities as a defendant for a time. But the bulk of that preclusion discussion has focused on federal caselaw and is therefore beside the mark, for the preclusive effect of a prior Illinois state court lawsuit is a matter of Illinois and not federal law (Marrese v. Am. Acad. of Orthopaedic Surgeons, 470 U.S. 373, 380-81 (1985), relying in principal part on the full faith and credit provision of 28 U.S.C. § 1738).
It is regrettable that federal District Courts lack the power to certify questions of state law to the Illinois Supreme Court, which has conferred that power solely on the United States Supreme Court and our Court of Appeals under its S.Ct. Rule 20.*fn2 After all, the complex issues of claim preclusion, and perhaps issue preclusion, that are posed here can be answered definitively only by the Illinois Supreme Court. But because that privilege is unavailable, this Court calls on Gallagher's counsel to file a reply, devoted to Illinois law alone, on the subjects of both claim preclusion and issue preclusion under the circumstances posed by this case.*fn3
GDI has also sought to insert federal antitrust contentions into its lawsuit at this point, a good example of its moving-target approach to the litigation (although the underlying facts have not changed, no such claim was brought into the case until the Complaint had undergone several transformations). Once again, the principles announced in Marrese, which held that any potential for a state court judgment's preclusive effect on such a federal claim -- a claim that could not have been raised in the suit that generated that judgment -- teach that the answer must also depend on state preclusion law under full faith and credit principles (470 U.S. at 379-83).
On that score nothing suggests that Illinois counts would deviate from the general proposition that the exclusivity of antitrust jurisdiction in the federal courts cannot be trumped by a judgment in a state court that itself had no power to entertain such a claim (although it is of course nonprecedenetial, the opinion by this Court's then colleague Honorable Paul Plunkett, who inherited the Marrese case post-remand, so held (628 F.Supp. 918-923-25 (N.D.Ill. 1986.)) Accordingly the earlier-ordered reply memorandum by Gallagher must address that issue as well.
As reflected here, further input from Gallagher is needed before the status of the Sixth Amended Complaint can be determined. For that purpose Gallagher will not be required to reinvent the wheel by restating arguments that it has made previously (this Court has retained the parties' filings in its chambers file). It will be permissible ...
