United States v. Noblesgreen
scotus · 1975 · cited in 9 Missouri opinions naming this issue, 1977–2025
2 sentences

2025“The work product doctrine is ‘an intensely practical [doctrine], grounded in the realities of litigation in our adversary system.’” Hill v. Wallach, 661 S.W.3d 786 , 791 (Mo. 2023) (quoting U.S. v. Nobles, 422 U.S. 225, 238 (1975)).

2023Therefore, the settlement documents are not protected by the work product doctrine, and there is no basis set forth in the writ petition for making the preliminary writ permanent. 11 Conclusion The work product doctrine is “an intensely practical [doctrine], grounded in the realities of litigation in our adversary system.” United States v. Nobles, 422 U.S. 225, 238 (1975).

Hickman v. Taylorgreen
scotus · 1947 · cited in 9 Missouri opinions naming this issue, 1977–2024
2 sentences

2024The work product privilege allows “a lawyer [to] work with a certain degree of privacy, free from unnecessary intrusion by opposing parties and their counsel.” Hickman v. Taylor, 329 U.S. 495, 511 (1947).11 The privacy afforded to lawyers by the work product privilege applies equally to information beneficial, as well as detrimental, to the attorney’s client or position at trial. 11 In Hickman, the United States Supreme Court first recognized the work-product privilege, and Missouri has since codified the privilege in Rule 56.01 and the privilege “is now firmly established in the common law.”

2023Overview of the Work Product Doctrine The work product doctrine had its genesis in the oft-cited and much-celebrated case of Hickman v. Taylor, 329 U.S. 495 (1947).

2024The premise of the doctrine comes from the need for counsel to “work with a certain degree of privacy, free from unnecessary intrusion by opposing parties and their counsel.” Hickman v. Taylor, 329 U.S. 495, 510 (1947); Cohen, 262 S.W.3d at 650 ; see United States v. Nobles, 422 U.S. 225, 238 (1975) (“interests of society and the accused in obtaining a fair 6 and accurate resolution of the question of guilt or innocence demand that adequate safeguards assure the thorough preparation and presentation of each side of the case”).

Halford v. Yandellgreen
moctapp · 1977 · cited in 4 Missouri opinions naming this issue, 1985–1993
2 sentences

1987The work product doctrine does not limit the power of the trial court to order production of statements of witnesses who “have testified at trial.” Similarly, Halford v. Yandell, 558 S.W.2d 400, 401 (Mo.App.1977), upon which appellant relies, makes the same conclusions.

1987The court recognized a distinction between “privilege” and “work product.” The Southern District differentiated between pretrial discovery and the use, at the time of trial, of a document produced during the trial, 558 S.W.2d at 405 , and held that the manner in which the statement was used by defense counsel to impeach Laferny, the witness, was not “vulnerable to the objection leveled against it, that objection being founded on the work product doctrine.” 558 S.W.2d at 406 .” The court recognized the important distinction between calling for a statement at a deposition and calling for a state
