Mary Santelli (plaintiff) worked for Electro-Motive (defendant), a division of General Motors Corporation. Electro-Motive discharged Santelli after she complained that Electro-Motive sexually discriminated against her. Santelli sued Electro-Motive for sex discrimination and retaliatory discharge. The court granted Electro-Motive's motion for summary judgment in part, but also denied the motion in part. Electro-Motive filed a motion to reconsider the partial denial of summary judgment, on the grounds that the court: (1) cited controlling Seventh Circuit case law while ignoring contrary case law from other circuits, (2) applied the wrong legal standard to compare Electro-Motive's treatment of its male and female employees, (3) misapplied the elements required to prove that a defense is pretextual, (4) mistakenly found that a reasonable trier of fact could agree with Santelli that her removal from an assignment was discriminatory, and (5) incorrectly described an incident that Electro-Motive considered relevant to the case.
