In Re: Subpoenas

Under Federal Rule of Criminal Procedure 17, a subpoena is valid only if it seeks information that is relevant and not unduly burdensome; a responding party may challenge a subpoena's scope on relevance and burden grounds before reaching any privilege analysis. The applicable standard depends on whether this is a grand jury or civil subpoena: grand jury subpoenas receive deferential review (enforced unless harassing or clearly irrelevant), while civil subpoenas are subject to a more rigorous balancing test weighing the requesting party's need against the respondent's burden. Once the subpoena clears the scope/relevance threshold, a party may assert attorney-client privilege, executive privilege, journalist's privilege, or other protections, but must establish each claim specifically for withheld materials and demonstrate the privilege has not been waived. The court's resolution will hinge on both the legitimacy of the subpoena's scope and the strength of any privilege assertions against the withheld communications or documents.
