A Wal-Mart dispute revealed the sexual discrimination at the US Supreme Court, when 3 female justices and other male colleagues conflicted with each other.

Female justices, Justices Ruth Bader Ginsburg, Sonia Sotomayor and Elena Kagan spoke about the worldwide discrimination and women being paid less than men.

All of them raised a question against Wal-Mart’s attorney, Theodore Boutrous. But in response to it, he said that the company has strict policy against gender discrimination. He said that if Supreme Court approves the case to go forward, then it will be the discrimination.

Ginsburg asked Boutrous is gender discrimination at work? She asked him that how corporate decision-makers hire people like themselves.

Meanwhile, Sonia Sotomayor legitimated the use of statistical analysis in discrimination cases.

Though, Kagan said, “I guess I’m just a little bit confused as to why excessive subjectivity is not a policy that can be alleged” as the basis of a job-discrimination suit”.

These queries put them in conflict with Justices Antonin Scalia and Anthony Kennedy.

Attorney, Joseph Sellers, said that despite of being at senior post, women being paid less than men. He made an argument on the behalf on female plaintiffs about gender discrimination.

On the other hand, the Wal-Mart argues that in order to qualify as a class, the women need to satisfy the so called "commonality requirement."
