Facts of Case
In this case we consider the constitutionality of the kidnapping in the first degree statute under the due process void-for-vagueness doctrine and conclude that the statute is not unconstitutionally vague.
In late 1986, the defendant James E. Worrell, Jr., went to a construction site and forced John Bishop at gunpoint to leave the site with him. He took Bishop to the retail shop of the defendant's wife at a local shopping mall. As the defendant himself declared in his written statement on plea of guilty, he took him there "with the intent of either doing great bodily harm to him or causing severe emotional distress to him ..."
At his wife's shop, the defendant held his wife, Bishop and another woman hostage for approximately 8 hours, using handcuffs and a gun to keep them there. Allegedly, Bishop and the defendant's wife were having an affair, and this precipitated the events in question. When a man who owned a neighboring shop attempted to help the hostages, the defendant fired two shots which frightened him off. The defendant also fired some shots into a wall, narrowly missing Bishop's head.
The hostages were eventually released. The defendant pleaded guilty to one count of kidnapping in the first degree and one count of assault in the second degree, as charged by amended information. The defendant, a former law enforcement officer, at his change of plea hearing was asked and answered as follows:
*539[The Court:] And did you know what you were doing was against the law at the time you did it; did you know these acts were unlawful; they were a crime?
[The Defendant:] Yes.
Thereupon the trial court accepted the defendant's guilty pleas and imposed a sentence within the standard range. Defendant obtained new counsel, who filed a notice of appeal. One principal issue is raised.
Issue
Under Fourteenth Amendment due process doctrine, is the statutory definition of "restrain" (an essential element of the crime kidnapping in the first degree) unconstitutionally vague because it uses the phrases "without legal authority" and "interferes substantially with his liberty"?1
Decision
Conclusion. Washington's kidnapping in the first degree statute is not unconstitutionally vague. Case law, and the statutory definition of "restrain" as contained in RCW 9A.40.010(1), put a reasonable person on notice of what conduct is prohibited. The statute itself is also sufficiently detailed to prevent arbitrary arrests and convictions.
A person can be charged under RCW 9A.40.020 with kidnapping in the first degree if he or she "abducts" another person. "Abduct" is defined in RCW 9A.40.010(2) in terms of "restrain"; "restrain", in turn, is defined in RCW 9A.40.010(1) in pertinent part as follows:
(1) "Restrain" means to restrict a person's movements without consent and without legal authority in a manner which interferes substantially with his liberty.
*540(Italics ours.) It is the defendant's assertion that the presence of the italicized phrases in this statute render it void for vagueness under the due process clause of the fourteenth amendment to the United States Constitution.
Under the Fourteenth Amendment, a statute is void for vagueness if its terms are "so vague that persons of common intelligence must necessarily guess at its meaning and differ as to its application." Myrick v. Board of Pierce Cy. Comm'rs, 102 Wn.2d 698, 707, 677 P.2d 140, 687 P.2d 1152 (1984).2 The test for vagueness rests on two important considerations: adequate notice to citizens and adequate standards to prevent arbitrary enforcement.3 As we recently stated:
In a constitutional challenge a statute is presumed constitutional unless its unconstitutionality appears beyond a reasonable doubt. Seattle v. Shepherd, 93 Wn.2d 861, 865, 613 P.2d 1158 (1980); [State v.] Maciolek, [101 Wn.2d 259] at 263 [676 P.2d 996 (1984)]. In a facial challenge, as here, we look to the face of the enactment to determine whether any conviction based thereon could be upheld. Shepherd, at 865. A statute is not facially vague if it is susceptible to a constitutional interpretation. State v. Miller, 103 Wn.2d 792, 794, 698 P.2d 554 (1985). The burden of proving impermissible vagueness is on the party challenging the statute's constitutionality. Shepherd, at 865. Impossible standards of specificity are not required. Hi-Starr, Inc. v. Liquor Control Bd., 106 Wn.2d 455, 465, 722 P.2d 808 (1986).
State v. Aver, 109 Wn.2d 303, 306-07, 745 P.2d 479 (1987).4
This is a facial challenge to the constitutionality of the statute, rather than a challenge to the statute as applied to *541the defendant. While the defendant presents his arguments without reference to the facts of the case, the State correctly argues that the facts should be considered. Although in the past this court once held that the factual setting of a case is irrelevant where the entire statute is challenged as vague,5 that approach has been modified by the United States Supreme Court and by more recent Washington case law.
In 1975 the United States Supreme Court held, " [i]t is well established that vagueness challenges to statutes which do not involve First Amendment freedoms must be examined in the light of the facts of the case at hand." United States v. Mazurie, 419 U.S. 544, 550, 42 L. Ed. 2d 706, 95 S. Ct. 710 (1975). In a yet later void-for-vagueness case, that Court also declared:
The court should . . . examine the facial vagueness challenge and, assuming the enactment implicates no constitutionally protected conduct, should uphold the challenge only if the enactment is impermissibly vague in all of its applications. A plaintiff who engages in some conduct that is clearly proscribed cannot complain of the vagueness of the law as applied to the conduct of others. A court should therefore examine the complainant's conduct before analyzing other hypothetical applications of the law.
(Footnote omitted.) Hoffman Estates v. The Flipside, Hoffman Estates, Inc., 455 U.S. 489, 494-95, 71 L. Ed. 2d 362, 102 S. Ct. 1186, reh'g denied, 456 U.S. 950 (1982).6
*542The defendant makes no claim that the statute in question (RCW 9A.40.010(1)) implicates constitutionally protected conduct. Here, we do not perceive that any reasonable person could disagree that the defendant's actions with respect to John Bishop were "without legal authority" and accomplished in a manner "which interferes substantially with his liberty". The defendant admitted as much when he pleaded guilty. The defendant's conduct was thus "clearly proscribed" and his facial vagueness challenge fails.7 By his own version of the facts, defendant has failed to show that the enactment is impermissibly vague in all its applications.
Were we to examine the defendant's challenge to the statute's constitutionality without considering the facts of this case, the challenge would still fail. The defendant relies on a number of cases that voided statutes containing language similar to the "without legal authority” phrase that is here challenged.8
In recent cases we have upheld statutes containing some version of the word "lawful",9 and in so doing have made it clear that we will not indiscriminately void any statute for vagueness simply because it uses the word "lawful" or "legal". The context of the language, of course, plays *543a key role.10 State v. Smith, 111 Wn.2d 1, 759 P.2d 372 (1988) is in point. In that case, we held that the phrase "without lawful authority" in the harassment statute (RCW 9A.46.020) did not render the statute void for vagueness, either for failure to give adequate notice of the conduct it proscribes or for failing to provide minimal guidelines for enforcement.11
In an effort to demonstrate a notice problem in the term "without legal authority" in this case, the defendant offers hypothetical examples of situations in which legal authority to restrain is, to his view, unclear. Such situations, however, can exist under a statute without mandating that the statute be stricken for vagueness. As we held in Smith, at 10, "we will not void a legislative enactment merely because all of its possible applications cannot be specifically anticipated." The defendant further argues that the phrase requires a legal conclusion and unreasonably forces citizens to search through statutes, administrative regulations, and court decisions in order to obtain notice of proscribed conduct.12 In Smith, however, this court contemplates the same "search" about which the defendant here complains:
People of common intelligence need not always guess at what a statute means by "lawful". Presumptively available to all citizens are the statements of law contained in statutes and in court rulings. Our cases make clear the important relevance of statutory and common law to the meaning of the concept of "lawfulness" as used in legislative enactments.
Smith, at 7.
Here, as in Smith, persons of ordinary intelligence are able to read the statutory definition of "restrain" (RCW 9A.40.010(1)) and determine what types of activity are *544being proscribed. As further guidance, if necessary, resort can be had to cases interpreting the statute.13 The defendant's argument that the statute fails to provide notice to citizens of proscribed conduct is unconvincing.
Also unconvincing is the defendant's argument that the statute is unconstitutional because it permits arbitrary arrests and convictions. As the defendant's argument goes, the statute gives the police unbridled discretion to arrest on an ad hoc basis when they believe the citizen's actions were without "legal authority". The statute, however, provides more than the minimal guidelines required to guide law enforcement. The terms are not inherently subjective in the context in which they are used. As we recently observed,
The mere fact that a person's conduct must be subjectively evaluated by a police officer to determine if that person has violated a statute does not make that statute unconstitutionally vague. If this were so, most criminal statutes would be void for vagueness. What is forbidden by the due process clause are criminal statutes that contain no standards and allow police officers, judge, and jury to subjectively decide what conduct the statute proscribes or what conduct will comply with a statute in any given case.
State v. Maciolek, 101 Wn.2d 259, 267, 676 P.2d 996 (1984).
In addition to arguing that the phrase "without legal authority" is unconstitutionally vague, the defendant also asserts that the statute is void for vagueness because of the Legislature's inclusion of the phrase "interferes substantially with his liberty". As the State points out, this phrase lends itself to a commonsense interpretation. Furthermore, the phrase has been interpreted in case law, providing additional guidance as to its meaning.14
*545The statute in question (RCW 9A.40.010(11)) being susceptible of a constitutional interpretation, we conclude that it is not facially vague.15 The defendant has not met his burden of showing the statute's unconstitutionality beyond a reasonable doubt.16
Affirmed.
Brachtenbach, Dolliver, Dore, Callow, and Durham, JJ., concur.
The defendant also claims the kidnapping statute is unconstitutional under article 1, sections 3 and 7 of the state constitution, but fails to use or even mention the interpretive principles set forth in State v. Gunwall, 106 Wn.2d 54, 720 P.2d 808 (1986). No violation of our state constitution is apparent; in any event, argument in this regard being insufficient we decline to further consider the claimed state constitutional issues. State v. Wethered, 110 Wn.2d 466, 472, 755 P.2d 797 (1988).
