(Bloomberg) –Women suing Goldman Sachs Group Inc. in one of the era's biggest Wall Street gender-discrimination lawsuits asked a federal judge this week to stop the bank from forcing more than 1,000 of them into arbitration.

Lawyers for the group argue that Goldman has waited too many years to now try to push them out of open court and into the closed-off system of arbitration. They cite their case's 755 docket entries, 376 discovery requests, 100 letters to the court, 44 motions, 33 days of depositions and 20 expert reports. Goldman said in a separate filing that arbitration is standard on Wall Street.

Cristina Chen-Oster, a former vice president at the bank, filed a preliminary complaint against Goldman in July 2005 — and last year a judge allowed her and co-plaintiffs to represent as many as 2,300 other current and former employees.
