Guillen was the first Latina officer hired by the department when she began in 2000, according to the complaint.
Attorneys for both sides spent two full days in downtown Los Angeles this week weeding through prospective jurors, setting the stage for opening arguments next week.
Guillen is one of five current and former officers who filed the lawsuit jointly, alleging harassment and discrimination.
Det. Steve Karagiosian, an Armenian American who was awarded $150,000 last month by a jury, was another plaintiff in the suit. He claimed fellow officers, including supervisors, repeatedly used anti-Armenian slurs.
Det. Jamal Childs, former Lt. Omar Rodriguez and former officer Elfego Rodriguez were all dropped from the lawsuit for various reasons.
Omar Rodriguez, who is of Cuban descent and has a case pending in federal court, was the first Latino promoted above the rank of sergeant at the department, according to the lawsuit.
The city was incorporated in 1911.
Former Deputy Chief William Taylor — who was among 10 officers, including Omar Rodriguez and Elfego Rodriguez, who were terminated in 2010 — filed a lawsuit in 2009 alleging he was retaliated against, demoted and ultimately fired because he blocked the firing of minority officers, among other reasons.
Taylor, who is white, was awarded nearly $1.3 million by a jury in March. The city recently filed a motion for a new trial.
Burbank has spent more than $1 million through March in legal fees on the Taylor case and at least $3.4 million in the lawsuit filed by Guillen and the other officers, according to city documents.
Those records do not include the costs involved for the Karagiosian trial since invoices had not been received by the city at the time they were made public.
