HAROLD BAER, JR., KIMBA M. WOOD, VICTOR MARRERO, U.S. District Judges:
Before the Court is the request of all defendants in the three above-captioned matters for this Court to determine whether the way in which the government used confidential informants to record certain conversations with targets of its investigation tainted the prosecution of defendants in each case such that some remedy is appropriate.
On December 2, 2011, the judges presiding over the above-captioned cases heard motions filed in each case by the government and third-party movants regarding Brady and attorney-client privilege issues. At the December 2, 2011 hearing, the Court resolved both the government's application to disclose certain recordings to defendants and the third parties' motions to prohibit the disclosure of certain potentially privileged material. During the course of that hearing, defendants and the third parties raised concerns that the government may have improperly obtained evidence that was subject to the attorney-client privilege through the use of confidential informants who created consensual recordings with various third parties during the course of the government's investigation.*fn1 Although the defendants' concerns were largely speculative because the recordings they received from the government were redacted to withhold privileged material, to better understand how the government managed its informants in this investigation, we decided to hold a hearing to determine if any portion of the government's cases is tainted by improperly obtained evidence.*fn2 On December 20, 2011, the Court allowed the defendants and government to present evidence and examine certain witnesses regarding the procedures that the FBI and DOJ Antitrust Division attorneys employed to record and manage the recordings in question in all three cases.
Following the hearing, the Court directed that on or before December 23, 2011 the defendants and government each file a letter detailing their positions as to whether the government investigation in these matters was tainted. The parties and third parties have also submitted letters and various exhibits, including recordings, transcripts, and other documentation regarding the use of confidential informants for the Court's review.
The central issue when evaluating an allegation that a prosecution has been "tainted" is "whether the evidence to which objection is made has been 'come at' by exploitation of illegal police conduct or by sufficiently different or distinguishable means to be pure or 'purged.'" United States v. Sapere, 531 F.2d 63, 64 n.1 (2d Cir. 1976) (citing Brown v. Illinois, 422 U.S. 590, 597-99 (1975); Wong Sun v. United States, 371 U.S. 471, 487-88 (1963)).
The standard for determining whether certain evidence is "tainted" depends upon the particular type of illegality alleged to be the source of that evidence. Because the defendants assert that government attorneys mismanaged confidential informants in a manner that created intrusions into the attorney-client privilege of investigation targets, the illegality alleged here is a violation of certain rules of professional conduct in existence at the time the recordings were made, namely, DR 7-104(A)(1).*fn3 DR 7-104(A)(1) states:
(A) During the course of his representation of a client a lawyer shall not:
(1) Communicate or cause another to communicate on the subject of the representation with a party he knows to be represented by a lawyer in that matter unless he has the prior consent of the lawyer representing such other party or is authorized by law to do so.
"Although disciplinary rules and rules of professional responsibility are not statutorily mandated, 'federal courts enforce professional responsibility standards pursuant to their general supervisory authority over members of the bar.'" S.E.C. v. Lines, 669 F. Supp. 2d 460, 463 (S.D.N.Y. 2009) (quoting United States v. Hammad, 858 F.2d 834, 837 (2d Cir. 1988)). In Hammad, the Second Circuit held that suppression is within "the arsenal of remedies available to district judges confronted with ethical violations" such as a violation of DR 7-104(A)(1). 858 F.2d at 842.*fn4 Defendants' requested relief begins here and goes much further, asking this Court to impose even more extensive remedies.
To prevail, the defendants bear "the initial burden of producing specific evidence demonstrating taint in a substantial portion of the Government's case against [them]." United States v. Sacco, 563 F.2d 552, 558 (2d Cir. 1977) (quoting Sapere, 531 F.2d at 66 (citations omitted)). If the defendants make this showing, the burden shifts to the government to prove the evidence is untainted. Id.; United States v. Magaddino, 496 F.2d 455, 459-460 (2d Cir. 1974).
The defendants argue that intrusions into attorney-client communications and joint defense communications by confidential informants, under the supervision of government agents, tainted the prosecution team in all three cases such that defendants are entitled to either dismissal of all three indictments, or in the alternative, dismissal of the conspiracy counts in the CDR case, preclusion of testimony from witnesses who engaged in the alleged misconduct, and barring the lawyers, agents, and paralegals who were exposed to said communications from continuing to participate in this case.
Defendants present evidence that in three different recordings, two confidential informants, Dean Pinard and Douglas Goldberg, inquired into and elicited information that was potentially subject to attorney-client privilege. However, whether or not this is so, the government has made clear that it will not introduce any of these recordings, nor evidence derived from these recordings, in its case-in-chief in any of the three trials.*fn5 Therefore, it appears that there is no valid concern that tainted evidence will be used in any of the cases because none of the material contained in even arguably ill-begotten portions of recordings will ...
