Most non-lawyers probably have no idea that the Delaware Chancery Court even exists. Thanks to Elon Musk and Twitter, it's about to become world-famous.
The Delaware court is the principal forum for legal disputes involving public corporations in the U.S. That's because most corporations take advantage of the state's corporation-friendly laws and procedures by incorporating in Delaware, which gives the chancery court jurisdiction over a huge universe of business disputes.
If you're a corporate lawyer, you better have the court's procedures and precedents at your fingertips. if you're anyone else, its rulings on contract law are snooze-inducing.
