United States v. Deleon
Opinion of the Court
*1270THIS MATTER comes before the Court on the United States' Sealed Motion Regarding Attorney Conflict, filed April 4, 2018 (Doc. 2071) ("Motion"). The primary issue is whether the Defendant Arturo Arnulfo Garcia's attorney, Billy Blackburn, can continue to represent A. Garcia notwithstanding Mr. Blackburn's prior representation of James Garcia, one of Plaintiff United States of America's witnesses, in a state court murder prosecution. In the case in which Mr. Blackburn represented J. Garcia, J. Garcia "was found guilty of Murder in the 2nd Degree, Tampering with Evidence and Possession of Firearm or Destructive Device by a Felon on November 28, 1995." Motion at 2. "The murder was not an SNM related homicide." Motion at 2.
The United States District Court for the District of New Mexico requires attorneys representing criminal defendants to "comply with the Rules of Professional Conduct adopted by the Supreme Court of the State of New Mexico." D.N.M. LR-Cr R. 57.2. Those rules impose two distinct duties vis-à-vis an attorney's former *1271clients.
That second duty applies, however, only to the matters in which an attorney represented a former client and to "substantially related" matters. N.M. R. Prof'l Conduct 16-109(A). A particular matter's scope-and, hence, whether it is the same matter in which an attorney represented a former client-"depends on the facts of a particular situation or transaction," but "[t]he underlying question is whether the lawyer was so involved in the matter that the subsequent representation can be justly regarded as a changing of sides in the matter in question." N.M. R. Prof'l Conduct 16-109 cmt. 2. A matter is substantially related to a matter in which an attorney represented a former client "if they involve the same transaction or legal dispute or if there otherwise is a substantial risk that confidential factual information as would normally have been obtained in the prior representation would materially advance the client's position in the subsequent matter." N.M. R. Prof'l Conduct 16-109 cmt. 3 (emphasis added). "Information acquired in a prior representation may have been rendered obsolete by the passage of time, a circumstance that may be relevant in determining whether two representations are substantially related." N.M. R. Prof'l Conduct 16-109 cmt. 3.
On April 5, 2018, the Court spoke with Mr. Blackburn ex parte regarding the details of the case in which Mr. Blackburn represented J. Garcia. Mr. Blackburn's representations to the Court indicate that he could not ethically cross-examine J. Garcia, because Mr. Blackburn might use or reveal confidential information relating to his prior representation of J. Garcia in such a cross-examination. See N.M. R. Prof'l Conduct 16-109(C). Nothing before the Court indicates, however, that Mr. Blackburn has any information related to J. Garcia's decades-old case that would advance A. Garcia's position if J. Garcia does not testify. On April 6, 2018, the United States and the Defendants removed J. Garcia from their witness lists. See United States' Unopposed Notice of Removal of Witness at 1, filed April 6, 2018. Consequently, there is no practical danger that Mr. Blackburn will use or reveal any nonpublic
Similarly, there is no substantial risk that information as would normally have been obtained in Mr. Blackburn's representation of J. Garcia in a non-SNM-related murder prosecution would materially advance A. Garcia's position in this case. See N.M. R. Prof'l Conduct 16-109 cmt. 3. Further, A. Garcia's federal prosecution for a Violent Crime in Aid of Racketeering,
To the extent that Mr. Blackburn's prior representation of J. Garcia creates any issues under the Sixth Amendment to the Constitution of the United States of America-e.g., by causing Mr. Blackburn to pull his punches while cross-examining J. Garcia-A. Garcia can unilaterally waive those issues. Conflicts of interest potentially create Sixth Amendment issues, because an attorney's divided loyalties may render their assistance constitutionally ineffective. See Cuyler v. Sullivan,
The Court grants the Motion insofar as it seeks a determination regarding whether Mr. Blackburn can ethically continue to represent A. Garcia. The Court denies the Motion-insofar as it seeks Mr. Blackburn's disqualification-because it concludes that Mr. Blackburn's representation of A. Garcia does not create a conflict of interest vis-à-vis Mr. Blackburn's former representation of J. Garcia. Out of an abundance of caution, however, the Court will seek a conflict-of-interest waiver from A. Garcia to avoid any Sixth Amendment issues, because such a waiver resolves any potential Sixth Amendment issues down the road.
IT IS ORDERED that: (i) the request for a determination in the United States' Sealed Motion Regarding Attorney Conflict, filed April 4, 2018 (Doc. 2071), is granted in part and denied in part.
In addition to the duties owed to a former client, the New Mexico Rules of Professional Conduct state that a lawyer cannot represent a client if "there is a significant risk that the representation of one or more clients will be materially limited by the lawyer's responsibilities to ... a former client." N.M. R. Prof'l Conduct 16-107(A)(2).
An attorney is permitted to use information relating to a former client's representation-as opposed to information relating to a current client's representation-if the information has become generally known. See N.M. R. Prof'l Conduct 16-109(C)(1).
