In this next clip, Justice Kagan tries to bring some perspective on what’s a stake in this case. In addition to overruling 40 years of precedent, Justice Kagan points out the thousands of contracts that public sector unions and governments have made in reliance of Abood and the millions of employees nationwide that would be affected if those contracts all of a sudden became void. Under the doctrine of stare decisis, the Court is required to take a long hard look at the possible negative consequences (economic or otherwise) of overruling any case. The question to Carvin, then, is what could possibly justify the mass upheaval forecasted to happen if the Court overrules Abood?
