BOSTON – A panel of appeals court judges on Wednesday repeatedly challenged the legal claims of a group that accuses Harvard University of intentional discrimination against Asian American students who apply to the Ivy League school. Circuit Court of Appeals in Boston appeared skeptical of arguments made by Students for Fair Admissions, which says Harvard imposes a “racial penalty” on Asian Americans. When a lawyer for the group accused the school of racial stereotyping against Asian American applicants, a judge interrupted and questioned the basis of the claim. The group's lawsuit alleges that Harvard admissions officers use a subjective “personal rating” assigned to each student to discriminate against Asian Americans. But Judge Sandra L. Lynch challenged that allegation, saying that, presented with competing statistical models from both sides, the trial court judge sided with Harvard's.
