Greg Stohr writes at Bloomberg Business Week:
When the U.S. Supreme Court reconvenes on Oct. 2, it will begin a term full of potential blockbuster cases. Disputes over partisan gerrymandering, cell phone privacy, and Donald Trump’s travel ban are already on the docket. Showdowns over public-sector union fees, antigay job discrimination, and voter-ID laws might be close behind. Out of all of them, the case that could be the most passionately fought is one that began as a brief discussion about a wedding cake in Colorado and has grown into a Supreme Court clash between free speech and equality.
