DuSablon nonetheless argues that JCB's state law claims involve significant questions of federal securities laws. But DuSablon cannot manufacture a basis for removal by injecting federal issues into a case under these circumstances. See Panther Brands, LLC v. Indy Racing League, LLC, 827 F.3d 586, 589 (7th Cir. 2016) (holding in a breach of contract action that an allegation that a defendant violated federal statutes is insufficient to create subject-matter jurisdiction). This is particularly so because, as the district court observed, DuSablon cited no cases supporting his position nor attempted to apply controlling law, namely Grable & Sons Metal Prods., Inc. v. Darue Eng'r & Mfg., 545 U.S. 308, 314-15 (2005) (invoking federal jurisdiction over state law claim to quiet title to property seized by federal government where the validity of the seizure was "the only legal or factual issue[] in the case"). 

Other considerations support the district court's exercise of discretion. The first is the court's finding that "DuSablon's conduct in defending the motion to remand" suggested that "removal was undertaken at least in part to delay a resolution of the noncompete issues to his benefit and to allow for a second bite at the apple after losing his motion to dismiss in state court." We see no clear error in this finding. The second consideration is the untimeliness of DuSablon's removal. Despite his claimed ignorance of the supposed substantial federal question until JCB responded to his motion to dismiss, DuSablon's motion itself raised many issues of federal law. The district court properly determined that DuSablon was or should have been aware of his asserted grounds for removal more than 30 days prior to his notice of removal.
