ON PETITION FOR REHEARING
Appellant Eliot S. Sash petitions the panel for rehearing to reconsider its decision in
Sash v. Zenk,
I. The Rule of Lenity and the Ex Post Facto Doctrine
In our earlier opinion, the threshold question was -whether this Court should resolve ambiguities in 18 U.S.C.
*63
§ 3624(b), the statute governing calculation by the Bureau of Prisons (BOP) of sentencing credits for good behavior in prison, also known as “good time” credit, by reference to the interpretive guidelines set forth in
Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc.,
The
ex post facto
doctrine is one of the Constitution’s several protections against retroactive application of legislation.
See Lynce v. Mathis,
It may seem strange that a statute can be considered “criminal” for some purposes and not for others.
See United States v. Bedonie,
Furthermore, it is clear that sentencing-administration statutes may be “criminal” for some purposes but not for others. For purposes of the Sixth Amendment right to counsel, for example, the prison disciplinary hearings that deprive inmates of good time are not considered “criminal.” The Supreme Court held in
Baxter v. Palmigi-ano,
Additionally, the Supreme Court has indicated that it is appropriate for the BOP to interpret sentencing-administration statutes like the one at issue here.
See Lopez v. Davis,
There are good reasons to treat the
ex post facto
doctrine as more expansive than the rule of lenity. The rule of lenity and the
ex post facto
doctrine are related, because both are concerned with notice and fair warning.
See United States v. Lanier,
Put another way, notice problems in the
ex post facto
context arise not from statutory ambiguity, but from retrospective changes in laws upon which citizens are entitled to rely.
See Weaver,
The fact that the
ex post facto
doctrine and the rule of lenity share a concern, for notice does not require that their scope be identical. We note that the vagueness doctrine is “related” to the rule of lenity and the
ex post facto
doctrine, because all concern fair notice,
see Lanier,
The application of the
ex post facto
doctrine is broader in scope than the application of the rule of lenity. The
ex post facto
doctrine applies to any penal enactment that retrospectively disadvantages a criminal offender, whether or not it increases a criminal sentence,
see Weaver,
The reason the
ex post facto
doctrine is broader than the rule of lenity in the area of sentencing administration is that there is a greater potential for unfairness when a legislature changes the law pertaining to a criminal offender’s sentence than when the legislature merely leaves a question open for future regulation by an administrative agency. This is demonstrated by the case of
Lynce v. Mathis,
which dealt with an
ex post facto
challenge to an unusual series of actions by the Florida legislature.
Lynce demonstrates why it is necessary that sentencing credits be treated as criminal for ex post facto purposes: the ex post facto doctrine condemns legislative acts that offend our fundamental sense that the government should not make more harsh the law governing the treatment of convicted criminals after their criminal acts are in the past. 5 The rule of lenity, however, deals with different concerns and employs a different analysis, and so it is not remarkable that the scopes of these doctrines should also differ or that we should consider a particular statute to be “criminal” in a way that implicates one doctrine but not the other. Accordingly, we decline to reconsider our holding that *67 § 3624(b) is not criminal for purposes of the rule of lenity.
II. Adequate Notice Was Given By Regulation
It is important to note that, even if we accepted Sash’s argument that § 3624(b) is a “criminal” regulation in this context, we would find that adequate notice was given by the BOP regulations that interpreted it. Sash argues that our holding that the rule of lenity does not apply to § 3624(b) implies that we believe the rule of lenity, were it applicable, would have to be applied prior to Chevron deference. This is not the case.
The Supreme Court has rejected the idea that the rule of lenity should trump the deference we traditionally afford to reasonable administrative regulations.
See Babbitt,
We have never suggested that the rule of lenity should provide the standard for reviewing facial challenges to administrative regulations whenever the governing statute authorizes criminal enforcement. Even if there exist regulations whose interpretations of statutory criminal penalties provide such inadequate notice of potential liability as to offend the rule of lenity, the “harm” regulation, which has existed for two decades and gives a fair warning of its consequences, cannot be one of them.
Id.
at 704 n. 18,
Indeed, the Supreme Court’s observation that defendants and judges routinely
*68
consider good time calculations in their decisions about plea bargains and sentencing supports our holding that there is no notice problem in this case.
See Weaver,
Here, neither we nor a prospective criminal need “guess as to what Congress intended,”
Ladner v. United States,
CONCLUSION
For the reasons discussed, the petition for rehearing by the panel is Denied.
Notes
. Sash also argues that § 3624(b) unambiguously supports his preferred reading of the statute. We reject this argument for the reasons stated in our earlier opinion.
. The two doctrines are also distinct in that the rule of lenity has an institutional purpose not shared by the
ex post facto
doctrine. The rule of lenity protects the principle that "because of the seriousness of criminal penalties, and because criminal punishment usually represents the moral condemnation of the community, legislatures and not courts should define criminal activity,”
United States v. Bass,
. The
ex post facto
doctrine does not apply to all regulation of matters that might be described in ordinary English as "criminal.” Some regulation of matters pertaining to the criminal process is "procedural” in nature and therefore not subject to
ex post facto
analysis.
See Dobbert v. Florida,
. Some matters pertaining to the treatment of criminal offenders are within the scope of the
ex post facto
doctrine, while others are not. The doctrine has been applied to a law that required the prison warden to keep secret from condemned prisoners the day and time of their execution where that law was applied retrospectively to prisoners whose crimes preceded its enactment.
In re Medley,
. The greater harm becomes clear if we imagine two highways. On the first, no speed limit is posted. The motorists are at a disadvantage, because they must guess the appropriate speed. On the second highway, a sign announces a speed limit of fifty-five miles per hour — but after a car goes by, the sign electronically alters itself to show a speed limit of twenty miles per hour. Motorists ticketed for violating the lower speed limit are understandably upset. Our sense of fairness is violated both by uncertainty in the law and by retrospective changes, but the need for greater protection in the ex post facto context is clear.
. Sash relies on the recent case of
National Cable & Telecommunications Association v. Brand X Internet
Services,- U.S. -,-,
In the passage upon which Sash relies, the Supreme Court noted that in the prior judicial interpretation, the court of appeals had “invoked no other rule of construction (such as the rule of lenity) requiring it to conclude that the statute was unambiguous to reach its judgment.” Id. This language does not imply that the court of appeals should have relied upon the rule of lenity prior to Chevron in its later review of the agency’s interpretation. Rather, it means that if the court, prior to an agency's interpretation, has found a statute unambiguous with the help of the rule of lenity, that finding will later be binding on the implementing agency. In the present case, the agency interpretation was issued before this Court confronted the question it resolved, so Brand X is not relevant here.
Neither this opinion nor our earlier opinion suggest that the rule of lenity never applies in the administrative context. We find only that where an agency gives clear notice of the meaning of a statute by regulation, and where it is reasonable to charge defendants with notice of the agency's interpretation, Chevron deference will apply prior to the rule of lenity.
