Pennsylvania Supreme Court Justice Joan Orie Melvin convicted of public corruption submitted her letter of resignation from the court to Governor Tom Corbett according to this article on Philly.com.
Orie Melvin is due to be sentenced May 7 and in a letter to Gov. Corbett said "it is with deep regret and a broken heart" that she tendered her resignation, effective May 1. "It has been my honor and privilege to serve the people of this Commonwealth for the past 28 years, and I am deeply saddened that I am not able to fulfill my commission."
Gov. Corbett can appoint an interim justice to fill her spot on the seven-member court, with the approval of two-thirds of the state Senate. The appointee would serve through January 2016. The court is currently split 3-3 between Republicans and Democrats and Orie Melvin is a Republican.
The justice still plans to appeal her conviction.
It should be noted that members of the House of both parties were calling for efforts to start impeachment proceedings against her. Instead she opted to perform her last action of public service and submit her resignation.
