GW will once again celebrate Constitution Day with a Supreme Court justice.

Justice Ruth Bader Ginsburg, a fierce advocate for women’s rights, will speak at Lisner Auditorium on Sept. 12 in a conversation with law professor Maeva Marcus, the University announced Friday. The sixth annual event celebrates the anniversary of the signing of the Constitution.

GW students, faculty and staff can order free tickets on a first-come, first-serve basis online starting Sept. 2 at noon. Ginsburg last spoke on campus in 2011, when she discussed the Affordable Care Act and the role of women on the Supreme Court.

Ginsburg, the second woman nominated to sit on the nation’s highest court, is an integral member of the court’s liberal wing. She is known for supporting women’s rights and has developed a loyal fan base through the popular “Notorious RBG” tumblr.

She will be the second Supreme Court justice to speak on campus this year, following Justice Sonia Sotomayor who attended the ribbon cutting of the Jacob Burns Legal Clinics building last spring.

Justice Antonin Scalia headlined the Constitution Day event last year, and talked about how he believes the Constitution does not hold the answers to all of the nation’s questions.
