"Exxon Mobil Corp. is asking the Supreme Court to block Massachusetts’s attorney general from demanding certain information in an investigation over climate change.
The nation’s largest oil company says that state Attorney General Maura Healey’s (D) wide-ranging demand for documents violates the “due process” clause of the Constitution’s 14th Amendment, since Exxon is headquartered outside of Massachusetts.
It’s an appeal of an April ruling by Massachusetts’s highest court, which said that the company had to comply with Healey’s civil investigative demand, akin to a subpoena."
