In a second dispute involving demands from federal regulators for documents, a federal magistrate judge in Washington ruled in November that JPMorgan could invoke attorney-client privilege to keep private e-mails requested by the Federal Energy Regulatory Commission.
The agency had accused a JPMorgan unit of making “factual misrepresentations” and omitting material information in communications with the California Independent System Operator, which operates the state’s power grid, and in filings to the commission. The FERC suspended the unit’s electricity-trading authority for six months starting April 1.
