Mr. Justice MURPHY delivered the opinion of the Court.
This case presents an important problem under the Federal Rules of Civil Procedure, 28 U.S.C.A. following section 723c, as to the extent to which a party may inquire into oral and written statements of witnesses, or other information, secured by an adverse party's counsel in the course of preparation for possible litigation after a claim has arisen. Examination into a person's files and records, including those resulting from the professional activities of an attorney, must be judged with care. It is not without reason that various safeguards have been established to preclude unwarranted excursions into the privacy of a man's work. At the same time, public policy supports reasonable and necessary inquiries. Properly to balance these competing interests is a delicate and difficult task.
On February 7, 1943, the tug 'J. M. Taylor' sank while engaged in helping to tow a car float of the Baltimore & Ohio Railroad across the Delaware River at Philadelphia. The accident was apparently unusual in nature, the cause of it still being unknown. Five of the nine crew members were drowned. Three days later the tug owners and the underwriters employed a law firm, of which responden Fortenbaugh is a member, to defend them against potential suits by representatives of the deceased crew members and to sue the railroad for damages to the tug.
A public hearing was held on March 4, 1943, before the United States Steamboat Inspectors, at which the four survivors were examined. This testimony was recorded and made available to all interested parties. Shortly thereafter, Fortenbaugh privately interviewed the survivors and took statements from them with an eye toward the anticipated litigation; the survivors signed these statements on March 29. Fortenbaugh also interviewed other persons believed to have some information relating to the accident and in some cases he made memoranda of what they told him. At the time when Fortenbaugh secured the statements of the survivors, representatives of two of the deceased crew members had been in communication with him. Ultimately claims were presented by representatives of all five of the deceased; four of the claims, however, were settled without litigation. The fifth claimant, petitioner herein, brought suit in a federal court under the Jones Act on November 26, 1943, naming as defendants the two tug owners, individually and as partners, and the railroad.
One year later, petitioner filed 39 interrogatories directed to the tug owners. The 38th interrogatory read: 'State whether any statements of the members of the crews of the Tugs 'J. M. Taylor' and 'Philadelphia' or of any other vessel were taken in connection with the towing of the car float and the sinking of the Tug 'John M. Taylor'.
Attach hereto exact copies of all such statements if in writing, and if oral, set forth in detail the exact provisions of any such oral statements or reports.'
Supplemental interrogatories asked whether any oral or written statements, records, reports or other memoranda had been made concerning any matter relative to the towing operation, the sinking of the tug, the salvaging and repair of the tug, and the death of the deceased. If the answer was in the affirmative, the tug owners were then requested to set forth the nature of all such records, reports, statements or other memoranda.
The tug owners, through Fortenbaugh, answered all of the interrogatories except No. 38 and the supplemental ones just described. While admitting that statements of the survivors had been taken, they declined to summarize or set forth the contents. They did so on the ground that such requests called 'for privileged matter obtained in preparation for litigation' and constituted 'an attempt to obtain indirectly counsel's private files.' It was claimed that answering these requests 'would involve practically turning over not only the complete files, but also the telephone records and, almost, the thoughts of counsel.'
