G v. District Court of Second Judicial District

Petitioners instituted this original proceeding under C.A.R. 21 seeking relief in the nature of prohibition from the order of the Presiding Judge of the 1975 Statutory Grand Jury, the Honorable Leonard Plank, respondent, which denied their motions (a) to quash grand jury subpoenas and (b) to vacate the order requiring petitioners to appear and testify before the grand jury. Petitioners challenged the subpoenas on four grounds: (1) that the subpoenas constituted unreasonable searches and seizures; (2) that they violated the privilege against self-incrimination; (3) that they violated the attorney-client privilege; and (4) that the subpoenaed material was exempt as the work-product of an attorney.
