In a fact-intensive decision issued on October 22, 2020, the Illinois Supreme Court determined in Sergiu Tabirta v. James J. Cummings, et al. that the mere presence of an employee’s home office in Cook County was insufficient, by itself, to establish proper venue over his employer in the jurisdiction. Merely having an employee with a home office in the venue was insufficient under the circumstances to constitute “doing business” or maintaining an “other office” there to satisfy the requirements of Illinois’ venue statute.
