A group of lawyers in a Kentucky lawsuit is pressing to shed light on information that Wall Street managers have fought for years to keep under wraps.

The move seems to be a warning that lawyers supported by former class-action kingpin William Lerach intend to use hardball tactics in a legal fight with KKR & Co., Blackstone Group LP and their founders. They were accused last month in a suit on behalf of Kentucky pensioners of misrepresenting "Black Box" bundles of hedge funds as safe investments when they were expensive and contributed to the state pension system’s virtual insolvency.
