Education

  • J.D., DePaul University College of Law, 1980
  • B.A., DePauw University, 1977

Admissions

  • Illinois
  • Goodson v. Industrial Commission et al., 190 Ill. App. 3d, 545 N.E.2d 975, 137 Ill. Dec. 214 (1st Dist. 1989): Mark secured dismissal of a claim for workers’ compensation benefits brought by a deceased workers’ wife. The petitioner alleged that her husband’s death was due to asbestos exposure while he was employed by the respondent. Mark successfully argued that the petitioner’s case was time barred, as the claim for death benefits is separate from the claim of the worker, and the law in effect on date of the worker’s death is controlling, not law at time of injury.
  • Martin v. Industrial Commission and Impact Industries, Inc., 227 Ill. App. 3d 217, 591 N.E.2d 108, 169 Ill. Dec. 228 (2nd Dist. 1992): Mark secured dismissal in the Appellate Court of Illinois, reinstating the Industrial Commission’s original decision denying workers’ compensation benefits. Through the introduction of expert testimony about the petitioner’s pre-existing cardiac condition and evidence of multiple outside stressors, Mark successfully argued that the petitioner’s heart attack was not work-related.
