between legislative and nonlegislative rules is a notoriously difficult issue.
Courts rely
on a collection of doctrinal factors, including the “agency’s label,”
the practical impact
on those covered by the rule,
and a legal effect test,
which looks to whether the rule
imposes legal rights or obligations.
Numerous formulations of these and other factors
are found in the courts of appeals.
With regard to statements in preambles challenged as legislative rules, courts must
wade into those same muddy waters. Interestingly, despite numerous challenges to
language in preambles as improper legislative rules, courts have consistently held that
statements in preambles are interpretive rules or general statements of policy, and thus
procedurally valid.
Because of the blurry lines of the distinction between legislative and
nonlegislative rules, it is difficult to tell whether this consistent practice is a result of the
caution exercised by agencies in their preambles to avoid any mandatory or binding
statements or simply a more relaxed judicial review of statements in preambles than in
separately issued guidance documents. Given that courts frequently invalidate separately
issued guidance documents, the trend is notable.
See, e.g., David L. Franklin, Legislative Rules, Nonlegislative Rules, and the Perils of the Short Cut, 120
YALE L.J. 276, 278 (2010) (suggesting there is perhaps “no more vexing conundrum in the field of
administrative law than the problem of defining a workable distinction between legislative and nonlegislative
rules.”).
See, e.g., Warshauer v. Solis, 577 F.3d 1330, 1337 (11th Cir. 2009) (the agency’s “characterization of the
rule is relevant”).
Cent. Tex. Tel. Coop., Inc. v. FCC, 402 F.3d 205, 214 (D.C. Cir. 2005) (noting that court had used a
substantial impact test); see also William Funk, A Primer on Nonlegislative Rules, 53 ADMIN. L. REV. 1321,
1325 (2001) (noting strain of cases looking to substantive impact on the regulated).
See, e.g., Miller v. Cal. Speedway Corp., 536 F.3d 1020, 1033 (9th Cir. 2008) (legislative rules “create
rights, impose obligations, or effect a change in the law”).
Troy Corp. v. Browner, 120 F.3d 277, 287 (D.C. Cir. 1997).
See, e.g., Am. Mining Cong. v. Mine Safety & Health Admin., 995 F.2d 1106 (D.C. Cir. 1993) (listing the
following factors: “(1) whether in the absence of the rule there would not be an adequate legislative basis for
enforcement action or other agency action to confer benefits or ensure the performance of duties, (2) whether
the agency has published the rule in the Code of Federal Regulations, (3) whether the agency has explicitly
invoked its general legislative authority, or (4) whether the rule effectively amends a prior legislative rule.”).
See, e.g., Troy Corp. v. Browner, 120 F.3d 277, 287 (D.C. Cir. 1997) (EPA’s premabular statement
“merely informed the public that the agency would exercise its discretion by considering exposure only for
low toxicity chemicals” and thus was a general policy statement); Fertilizer Institute v. EPA, 935 F.2d 1303,
1308-09 (D.C. Cir. 1991) (holding that EPA’s rule in its preamble was interpretive because it represents “the
agency’s attempt to interpret the meaning of a statutory provision”); Barrick Goldstrike Mines, Inc. v.
Whitman, 260 F. Supp. 2d 28, 38 (D.D.C. 2003) (“In this case, the interpretation [contained within the
preamble] . . . is within the scope of the regulation”); Bd. of Trustees of Knox Cnty. Hosp. v. Shalala, 959 F.
Supp. 1026, 1031 (S. D. Ind. 1997) (“Rather than create or destroy substantive rights, the [preambular] policy
simply clarifies what the Secretary believes the regulation means and explains how the Agency will apply
it.”); OSG Bulk Ships v. United States, 921 F. Supp. 812, 824 n.11 (D.D.C. 1996) (explaining that an
interpretation within the preamble does not transform the preamble into a legislative rule); Comité de Apoyo a
los Trabajadores Agrícolas v. Solis, No. 09-240, 2010 U.S. Dist. LEXIS 90155 at 47 (E.D. Pa. Aug. 30,
2010) (holding that the preambular language was an interpretation because the language was “very closely
tied” to the definition included in the regulation and “expressly purports to be an interpretation of that
definition”).
