I. CONSTITUTIONAL PROVISIONS
“No state shall.. .pass any bill of attainder, ex post
facto law, or law impairing the obligation of contracts..
. .” U.S. Const. art. I, § 10.
“The Legislature shall not pass any bill of attainder,
ex post facto law or law impairing the obligation of
contracts, or depriving a party of any remedy for
enforcing a contract which existed when the contract was
made.” N.J. Const.1947, art. IV, § VII, ¶ 3.
II. STATE CONSTITUTIONAL PROHIBITION
COMPARED WITH FEDERAL CONSTITU-
TIONAL PROHIBITION
The New Jersey ex post facto clause is not construed
more expansively than its federal counterpart. State v.
Kaplan, 178 N.J. Super. 487, 495 (App. Div. 1978).
III. GENERAL DEFINITIONS
Generally, an ex post facto law is one which makes a
prior act that was innocent when committed a crime,
which makes punishment for a crime more burdensome
after its commission, or which deprives a defendant of a
defense available when the act was committed. State v.
T.P.M., 189 N.J. Super. 360, 366 (App. Div. 1983),
citing Dobbert v. Florida, 432 U.S. 228, 292 (1977)
(defining “ex post facto” precisely in those terms).
The ex post facto clause prohibits any law which, in
relation to the past offense or its punitive consequences,
alters the situation of the offender to his disadvantage.
State v. Humanik, 199 N.J. Super. 283 (App. Div. 1985),
certif. denied, 101 N.J. 266 (1985), quoting State v.
T.P.M., 189 N.J. Super. at 366-367. See also State v.
Chapman, 187 N.J. Super. 474, 477 (App. Div. 1982),
and cases cited therein.
IV. PURPOSES OF THE PROHIBITION
The purpose of the prohibition is to secure
substantial personal rights against arbitrary and
oppressive legislation. State v. T.P.M., 189 N.J. Super. at
366, citing Dobbert v. Florida, 432 U.S. at 293, and State
v. Davis, 175 N.J. Super. 130, 147 (App. Div. 1980),
certif. denied, 85 N.J. 136 (1980).
The prohibition’s drafters intended thereby “to
assure that individuals had fair warning of the impact of
legislation and could rely on its meaning.” State v.
T.P.M., 189 N.J. Super. at 366, citing Weaver v. Graham,
450 U.S. 24, 28-29 (1981).
V. APPLYING THE PROHIBITION (GENERAL
PRINCIPLES)
A. Application Limited to Statutes Operating
Retrospectively
“The statute in question must be retrospective,
altering the legal consequences of acts completed before
its effective date.” State v. T.P.M., 189 N.J. Super. at 367,
citing Weaver v. Graham, 450 U.S. at 29.
B. Application Limited to Penal (Criminal) Statutes
The prohibition “applies only to statutes that are by
their nature penal.” Matter of Coruzzi, 95 N.J. 557, 578
(1984). See also In re Garay, 89 N.J. 104, 111 (1982)
(the prohibition “applies only to criminal laws”), and
cases cited therein, including Galvan v. Press, 347 U.S.
522, 531 n.4 (1954). Accordingly, the prohibition
applies only to criminal penalties and not civil penalties.
In re Garay, 89 N.J. at 111-113. United States v. Ward,
448 U.S. 242, 249 (1980), “sets forth the inquiry to be
followed in deciding whether a penalty is criminal or
civil.” In re Garay, 89 N.J. at 112.
Primarily, the determination of whether a penalty is
civil or criminal is a matter of statutory construction.
United States v. Ward, 448 U.S. at 248; In re Garay, 89
N.J. at 112.
Where the legislature has labeled the penalty civil,
that expression of legislative purpose is accorded
substantial weight. Such a penalty will be deemed
criminal only upon “the clearest proof” that the sanction
is punitive either in purpose or effect. United States v.
Ward, 448 U.S. at 248-249; In re Garay, 89 U.S. at 112.
Some of the factors to be examined in determining
whether a sanction is civil or criminal are set forth in
Kennedy v. Mendoza-Martin, 356 U.S. 86, 168-169
(1963). In re Garay, 89 N.J. at 113.
The United States Supreme Court has never rejected
Congress’ designation of a penalty as civil when the
sanction was merely monetary. In re Garay, 89 N.J. at
112.
