Grand Jury Privilege Fight

The justices on Monday granted review in a grand jury fight between the United States and a law firm over whether attorney-client privilege protects communications involving both legal and business advice.

The case, In Re Grand Jury, stems from a criminal investigation into the owner of an unnamed company. A grand jury issued subpoenas to the company and its law firm for certain documents and communications. Some documents were produced but others were withheld on attorney-client privilege and work-product protection grounds.
