The express prohibitions against tampering with witnesses and parties contained in former 18 U.S.C. §§ 1503 and 1505, are now in paragraphs (b)(1) and (2) of 18 U.S.C. § 1512. (As discussed in this Manual at 1724 and 1727, the omnibus clauses of these provisions still cover witnesses.) All forms of tampering with informants covered in former 18 U.S.C. § 1510, with the exception of tampering by means of bribery, are now proscribed by 18 U.S.C. § 1512(b)(3). Tampering with informants by means of bribery remains an 18 U.S.C. § 1510 offense.
Section 1512 augments the prohibitions of the former law in several important respects. First, section 1512(b)(3) sweeps more broadly than former 18 U.S.C. § 1510 and expands the class of informants protected by Federal law. For example, it protects individuals having information concerning a violation of a condition of probation, parole, or bail whether or not that violation constitutes a violation of any other Federal criminal statute. Second, it protects individuals seeking to provide information to Federal judges or Federal probation and pretrial services officers.
Section 1512 also includes attempts in its list of prohibited conduct. There is no requirement that the defendants actions have the intended obstructive effect. See, e.g., United States v. Murray, 751 F.2d 1528 (9th Cir.), cert. denied, 474 U.S. 979 (1985); United States v. Wilson, 796 F.2d 55 (4th Cir. 1986), cert. denied, 479 U.S. 1039 (1987). As amended by the Criminal Law and Procedure Technical Amendments Act of 1986, Pub. L. 99-646, it is clear that the killing of a witness or attempts to kill a witness in order to prevent his/her testimony constitutes an act of force intended to "influence the witness' testimony." See 18 U.S.C. § 1512(a). This change was necessitated by one court interpreting former § 1512 as not reaching an act of attempted murder that was intended to prevent a witness from testifying. See United States v. Dawlett, 787 F.2d 771 (1st Cir. 1986).
The section specifically abolishes the pending proceeding requirement of 18 U.S.C. §§ 1503 and 1505. The provision also eliminates ambiguity about the class of individuals protected. Although the former law protected witnesses, parties, and informants, it was unclear whether that law reached the intimidation of third parties (for example, the spouse of a witness) for the purpose of intimidating the principal party. Section § 1512 of Title 18 plainly covers such conduct, for it speaks of conduct directed toward "another person." See 128 Cong. Rec. H8203 (daily ed. Sept. 30, 1982).
Section 1512 protects potential as well as actual witnesses. With the addition of the words "any person," it is clear that a witness is "one who knew or was expected to know material facts and was expected to testify to them before pending judicial proceedings." United States v. DiSalvo, 631 F.Supp. 1398 (E.D. Pa. 1986), aff'd, 826 F.2d 1054 (3d Cir. 1987). Under § 1512, an individual retains his/her status as a witness even after testifying. United States v. Wilson, 796 F.2d 55 (4th Cir. 1986), cert. denied, 479 U.S. 1039 (1987) (protection of witness under § 1512 continues throughout the trial); United States v. Patton, 721 F.2d 159 (6th Cir. 1983) (witness retains status while defendant's motion for a new trial is pending); United States v. Chandler, 604 F.2d 972 (5th Cir. 1979) (witness retains status while case is pending on direct appeal). Cf. United States v. Risken, 788 F.2d 1361 (8th Cir.), cert. denied, 479 U.S. 923 (1986) (party was a witness after asserting his Fifth Amendment privilege and being dismissed from the stand since he could be recalled at any time).
Section 1512 of Title 18 contains two significant additions to the types of tampering barred by Federal law. First, it forbids "misleading conduct," as defined in 18 U.S.C. § 1515. Such conduct was not covered in those circuits that had narrowly construed the omnibus clauses of 18 U.S.C. §§ 1503 and 1505 under the rule of ejusdem generis. See United States v. Metcalf, 435 F.2d 754 (9th Cir. 1970); United States v. Essex, 407 F.2d 214 (6th Cir. 1969). see generally, 128 Cong. Rec. H8203 (daily ed. Sept. 30, 1982). Second, 18 U.S.C. § 1512 makes intentional harassment a misdemeanor. This offense is intended to reach conduct less egregious than the corrupt, threatening or forceful conduct required for a violation of former 18 U.S.C. §§ 1503 and 1505. Harassing conduct has been defined as that intended to badger, disturb or pester. Wilson, supra.
Despite its coverage, section 1512 was not intended to reach all forms of witness tampering. Its coverage is limited to tampering accomplished by the specific means enumerated in the provision. United States v. King, 762 F.2d 232 (2d Cir. 1985), cert. denied, 475 U.S. 1018 (1986). The more imaginative types of witness tampering as well as forms of tampering defying enumeration were still prohibited by the omnibus provision of § 1503. United States v. Lester, 749 F.2d 1288 (9th Cir. 1984).
It is unclear whether 18 U.S.C. § 1512(b)(3) was intended to widen the prohibition against obstructing investigations contained in former 18 U.S.C. § 1510 to include investigations that are not per se criminal in nature, such as an FAA investigation of an aircraft accident, or a Senate committee investigation of the trucking industry. A comparison of the difference in phraseology between 18 U.S.C. §§ 1510 and 1512(b)(3), however, indicates that those differences are differences of style, not substance, and that no such expansion was intended. Section 1510 proscribes interference with "the communication of information relating to a violation of any criminal statute of the United States . . ." to a (Federal) criminal investigator; 18 U.S.C. § 1512(b)(3) proscribes interference with "the communication to a (Federal) law enforcement officer . . . of information relating to the commission or possible commission of a Federal offense." There is nothing to indicate that Congress intended to depart from the generally accepted meaning of "law enforcement" as criminal law enforcement and of "offense" as criminal violation. See 18 U.S.C. § 1515(4); 128 Cong. Rec. H8203 (daily ed. Sept. 30, 1982). Accordingly, prosecutions for interference with legislative or administrative investigations that have not taken on the character of a criminal investigation should be brought under the omnibus clause of 18 U.S.C. § 1505. See this Manual at 1726.
