Adam Liptak, writing in the New York Times, prognosticates that this term of the U.S. Supreme Court could define Chief Justice John Roberts Jr.'s legacy with possible cases about whether gay Americans have a constitutional right to marry and about federal subsidies to consumers who purchase health-care coverage through federally run insurance exchanges. "Chief Justice John G. Roberts Jr. is entering his 10th term, and it is one that could define the legacy of the court he leads. Should the court establish a right to same-sex marriage, it would draw comparisons to the famously liberal court led by Chief Justice Earl Warren, said David A. Strauss, a law professor at the University of Chicago," Liptak reports. The justices have not decided whether to take up cases involving same-sex marriage or Obamacare yet.
