Funding the defense doesn’t make you a co-client entitled to see all of the privileged documents in a case, a federal judge has ruled, interpreting unsettled Pennsylvania law over which federal and state courts have been split.

Camico Mutual Insurance Co. can’t claim the “common interest” or “co-client” exception to attorney-client privilege in its bid to get documents from Heffler, Radetich & Saitta, a company it insures, in order to support its case that it is responsible for only up to $100,000 in Heffler’s legal defense in another case, the court ruled.
