Allergan Breast Implant Lawsuit Lawsuit in Illinois

Illinois plaintiffs may join MDL 2921 (D.N.J., Judge Brian R. Martinotti) or file in Illinois state court. Illinois does not have a BIOCELL-specific consolidated state court proceeding. Federal filings from Illinois are filed in the Northern District of Illinois (Chicago Division, Eastern Division) before transfer to D.N.J. under the MDL order. Cook County Circuit Court's Law Division handles large-volume product liability filings and could manage coordinated BIOCELL claims if state court filings reach sufficient numbers.

Illinois applies a two-year statute of limitations for personal injury under 735 ILCS 5/13-202. The discovery rule tolls this period from when the plaintiff knew or reasonably should have known of the injury and its probable wrongful cause — for BIA-ALCL, typically the diagnosis date. Illinois courts have applied the discovery rule in medical device and latent disease contexts. Illinois also has a four-year statute of repose for products liability under 735 ILCS 5/13-213, running from the date of first sale or delivery, which is a critical deadline for older BIOCELL placements predating 2022.

Cook County Circuit Court, Law Division (Chicago) is the primary Illinois state court venue, with Richard J. Daley Center hosting complex civil litigation. The Northern District of Illinois, Eastern Division (Chicago) before judges such as Judge Joan Gottschall or Judge Matthew Kennelly handles complex federal product liability matters. Illinois applies the Frye standard for novel expert testimony in state court (People v. McKown), distinct from the federal Daubert standard applicable in MDL 2921.

Illinois BIOCELL exposure is concentrated in the Chicago metropolitan area — particularly the Gold Coast and North Shore plastic surgery corridors, suburban Cook County, DuPage County, and Lake County. Major academic medical programs at Northwestern Memorial, Rush University Medical Center, and University of Chicago Medicine placed textured implants during the relevant period. Illinois also has a manufacturing and distribution nexus relevant to supply chain defendants: Allergan's North American operations have logistics connections to the Midwest.
