An attorney who sued her former firms’ banking clients, claiming they conspired against her to block a new bond structure she developed, does not have standing to allege an antitrust injury, a state court judge has ruled, finding her only a “vendor of services” and not a competitor.

Linda Grant Williams, who practiced at Pillsbury Winthrop Shaw Pittman and Greenberg Traurig, claims Citigroup, JPMorgan Chase and Goldman Sachs boycotted her new bond structure, and the banks’ threats led the two law firms to fire her. The banks serve as underwriters to bonds that finance the construction of airport terminals.
