Even as the legal profession pledges to bolster diversity in its workforce, the number of female lawyers who argue before the U.S. Supreme Court is still bafflingly low.

At a recent Women’s Bar Association of the District of Columbia panel discussion titled “Supreme Court Advocacy: Where are the Women?” Williams & Connolly partner Sarah Harris reported that in the last Supreme Court term, 31 of the 184 appearances were women. That amounts to 17%, lower than some other recent terms, as tallied by SCOTUSBlog.
