When the Supreme Court decides how the law, and the Constitution, should be interpreted in a case, that interpretation becomes a precedent. Once that judicial precedent has been set, it's understood that the interpretation and its reasoning should be applied to similar cases in the future. So why might the Supreme Court reconsider its own precedent? And what happens when a precedent is modified, or overruled? 

We talk to Nina Varsava, a law professor at University of Wisconsin, Madison who studies judicial precedent, and wrote the article, "Precedent on Precedent," and Rachel Rebouche, a law professor at Temple University who specializes in family law, health care law, and comparative family law, and has written about the potential impact of overturning Roe v Wade.
