As reported by GlobeSt.com, Bank One filed suit in November 2002 seeking $120 million in compensatory and punitive damages. The suit, filed in Cook County Circuit Court, claimed Jones Lang LaSalle pushed a series of sale-leaseback deals involving its properties, mostly to generate commissions. In addition to denying those allegations, Jones Lang LaSalle counter-sued, claiming Bank One owed $1.2 million in fees, according to documents filed with the Securities and Exchange Commission. Bank One had been a Jones Lang LaSalle client since March 1999, after the financial services company acquired First Chicago.

Specifically, Bank One had accused Jones Lang LaSalle of providing inaccurate financial analyses of sale-leasebacks, according to the November 2002 lawsuit. The bank also charged the real estate services firm with padding bills and faulty asbestos removal.

However, a Cook County Circuit Court judge agreed with Jones Lang LaSalle in December 2003 that Bank One failed to prove it suffered $40 million in damages, according to an SEC filing. Bank One amended its lawsuit without a specific damage amount, but Jones Lang LaSalle succeeded in getting six of the 10 counts dismissed last November, the company added in its filing.
