The University of California system was sued on Monday by a student group for alleged racial discrimination in admissions by favoring Black and Hispanic applicants over Asian-American and white applicants.

The state’s elite campuses, prohibited from using race-based admissions for decades, are now admitting more Black and Hispanic students. A new group is suing, arguing the university system is cheating.

Case alleges that UC schools show preference to Hispanic and Black applicants, and seeks to stop the schools from asking about race during admissions process.
