Governor Tom Corbett signed House Bill 492 into law on Tuesday afternoon in Harrisburg.
The law gives victims, or their families, the opportunity to speak before the Pennsylvania Board of Probation and Parole.
It is in response to the case of Rafael Robb, who killed his wife, Ellen, in Upper Merion Township in 2006.
Ellen Robb's family had to fight to win time in front of the state parole board.
The family was there Tuesday for the signing.
It takes effect on September 1st.
