Legislative Displacement
Necessity (choice of evils)
Legislative Displacement
Subsection (1)(a) asks which side of a value conflict is heavier, and the factfinder answers by weighing the harms at trial. Subsections (1)(b) and (1)(c) ask a question that comes first in logic: whether the legislature has already answered the conflict, in which case there is nothing left for the factfinder to weigh.1 The Comment describes this fourth limitation directly. The general choice of evils defense cannot succeed if a deliberate legislative choice has already foreclosed the issue of competing values, whether because some provision of the law deals explicitly with the specific situation or because a legislative purpose to exclude the claimed justification otherwise appears.2 The legislature, so long as it acts within constitutional limits, is always free to make that choice and have it prevail.3
The defense is therefore residual, and the reason follows from what the defense is. A defendant who pleads necessity concedes that the conduct satisfied the offense as written, and the Comment describes the claim as an interpretation of the law of the offense: the special situation calls for an exception that the legislature could not reasonably have intended to exclude, given the competing values.4 That interpretation presumes a legislature that framed its prohibition without cases of this kind in view. Once the legislature has looked at the situation and chosen, the presumption has nothing to work on, and a court that weighed the same values again would put its own ranking in place of the ranking of the elected body best placed to make such judgments.5 Incentive points the same way. Every condition a legislature attaches to an exception (a notice requirement, a permit, a time limit) would invite a defendant to argue at trial that the condition should be waived on the facts, and the legislature's drafting would lose its force. The two clauses find the legislature's answer in different places, with clause (b) looking for a specific provision and clause (c) looking to the purpose behind the law, and each is taken in turn below.
Specific Statutory Exceptions
Section 3.02(1)(b) makes the general defense available only if neither the Code nor other law defining the offense provides exceptions or defenses dealing with the specific situation involved.6 The clause has three parts, and each does separate work. The source must be the Code or the other law that defines the offense, because that is where the legislature records its value choice about this particular crime, and it is the same text a necessity claim asks a court to interpret. The provision must be an exception or a defense, meaning a legislative statement of when the otherwise prohibited conduct is permitted. And it must deal with the specific situation involved, which is the part that decides most disputes, since an exception written for one situation says nothing about a different one.
A provision that does address the defendant's situation controls the result, and it controls in both directions. The defendant who meets its terms is protected by the provision itself. The defendant who misses one of its conditions cannot reach for § 3.02 to supply what the provision requires, because the conditions are part of what the legislature decided about that situation.7 Legislatures have done this most visibly with self-defense, which is probably best understood as a species of necessity that the law has given its own, more detailed rules, so a claim of that kind is analyzed under the specific provision first.8
The Comment's own example of the defense at work is the climber lost in a storm who takes refuge in a house, and a trespass law that never mentions shelter is the kind of prohibition that leaves such a case to the general principle.9 Students go wrong when they treat an exception aimed at some other situation as though it displaced the defense, because the clause asks whether the legislature dealt with the situation this defendant faced, and exceptions for utility workers or surveyors answer different questions. The error also runs in reverse. When a statute does speak to the situation, a defendant cannot rescue the claim by pointing out that a jury might find the harm avoided greater, since (1)(b) ends the general defense and makes the balance irrelevant.
Contrary Legislative Purpose
Section 3.02(1)(c) reaches the case in which no specific exception exists but the justification still fails, because a legislative purpose to exclude the claimed justification plainly appears.11 Two words in the clause carry the doctrine. The word otherwise tells the reader that the purpose is found somewhere other than in a provision that deals with the situation, such as a statute that states in terms that no emergency excuses the conduct, or a regulatory scheme whose design shows that the legislature weighed this very conflict and chose a side. Courts state the same limit in their lists of elements when they require that the legislature has not determined the matter against the defendant, or has not acted by a clear and deliberate choice regarding the values at issue.12
The word plainly sets the standard of proof for that purpose, and the structure of the Code explains why the bar is high. Every criminal prohibition reflects a legislative judgment that the harm it targets matters. If that judgment alone showed a purpose to exclude necessity, clause (c) would swallow the defense, because no offense could ever be justified. The defense exists because prohibitions are framed without unusual cases in view, and a developed legal system needs better ways of handling those cases than the bare letter of each prohibition.13 The only legislature that displaces the defense under (c) is therefore one that looked at the claimed justification and rejected it. The severity of the penalty or the absoluteness of the prohibition does not show that, and doubt about the legislature's purpose leaves the defense in place.
The two displacement clauses are easy to run together, but they describe opposite legislative acts. Under (b) the legislature has written a narrower answer of its own, an exception or defense with defined conditions. Under (c) the legislature has said no to the justification in this setting, and it has said so plainly. The exam error to avoid is treating a harsh or unqualified prohibition as an exclusion in itself, since the clause asks for evidence that the legislature considered the claimed justification, and evidence that the offense is serious does not supply it. With the legislature's role settled, the next section turns to the actor's own conduct, because even a defendant who survives these clauses can lose the defense through fault in creating or appraising the emergency.
Specific Statutory Exceptions
Section 3.02(1)(b) is the first of the two clauses through which the legislature's own answer displaces the general defense, and it asks a drafting question before it asks a moral one. The defense is available only if "neither the Code nor other law defining the offense provides exceptions or defenses dealing with the specific situation involved."15 The clause names three things worth separating. The first is where to look: the Code or the other law defining the offense charged, because that text is where the legislature records its value choice about this particular crime. The second is what to look for: an exception or a defense, meaning a legislative statement of when otherwise forbidden conduct is permitted. The third is how closely the provision must fit, and here the words are exact, since it must deal with the specific situation involved. A provision addressed to the same general subject but to a different situation therefore leaves the clause unsatisfied.
When a provision does fit, it governs from both sides. A defendant who satisfies its terms is protected by the provision itself and has no need for § 3.02. A defendant who misses one of its conditions cannot borrow the general defense to supply what the provision requires, because those conditions are part of what the legislature decided about that situation.16 The reason follows from what the necessity defense is. The Comment describes it as an interpretation of the law of the offense, resting on the idea that a special situation calls for an exception the legislature could not reasonably have meant to exclude.17 That kind of interpretive exception is needed only where the legislature left a gap, and once the legislature has written an exception the gap is filled. The exception's limits (who may act, in what circumstances, with what safeguards) are the legislature's resolution of the same conflict the defendant now wants a jury to resolve again. Incentive points the same way. A defendant who falls just outside an exception always has a reason to call its limit arbitrary, and if the general defense could widen the exception, every condition would become a default that any sympathetic defendant could waive. The Comment confirms that the legislature, acting within constitutional limits, is always free to make such a choice and have it prevail.18
The variable that moved between the two versions was whether the legislature had spoken to the emergency at all. A third version shows the other side of the line. If the statute exempted only licensed veterinarians, it would speak to drug dispensing as a subject without speaking to the bystander's situation, and (1)(b) would not apply. Students lose this clause when they treat the same general subject matter as though it were the same specific situation, because the question is whether the legislature dealt with the situation this defendant faced. The error also runs in reverse. Where a statute does address the situation, a defendant gains nothing by arguing that a jury would find the harm avoided greater, since (1)(b) ends the general defense and the weighing under (1)(a) never takes place. The next clause, § 3.02(1)(c), covers the case in which no specific provision exists but the legislature's rejection of the claimed justification still plainly appears.19
Contrary Legislative Purpose
Section 3.02(1)(b) removes the general defense when the law defining the offense contains a provision written for the defendant's situation. Clause (c) removes it in a second way, when no such provision exists but the legislature's rejection of the claimed justification is still evident. The defense is lost if a legislative purpose to exclude the justification claimed otherwise plainly appears.21 The word otherwise tells the reader that this purpose is found somewhere other than in an exception or defense dealing with the specific situation. It might appear in a statute that says in terms that no emergency excuses the conduct, or in a regulatory design showing that the legislature confronted this very conflict of values and chose a side. Both clauses rest on one premise: when the competing values have already been foreclosed by a deliberate legislative choice, a defendant's claim of necessity does not reopen them.22
Two features of the clause need separate treatment, because each guards against a different mistake. The first is its object. The purpose must be one to exclude the justification claimed, and every offense already reflects a purpose to punish the conduct it describes. If that general purpose were enough, clause (c) would apply in every prosecution and the defense could never succeed for any offense. The second feature is the standard of proof, since the purpose must plainly appear. A general justification exists to supply an answer in situations that lawmakers did not foresee when they framed a prohibition. Silence in a statute therefore usually means the situation went unforeseen, and treating silence as exclusion would turn an unforeseen case into a rejected one with no evidence that anyone rejected anything. The standard also checks an incentive. A prosecutor will nearly always find it convenient to say the legislature meant its prohibition to be absolute, and the word plainly requires that the claim rest on evidence of what the legislature actually did.
That evidence can take several forms. The text may state the exclusion, as when a statute declares that no claim of necessity or emergency excuses a violation. The structure of a regulatory scheme may show it, as when the legislature creates an exclusive procedure for handling the conflict the defendant says justified the offense. The enactment history may show it, as when an exemption for the claimed justification was put before the legislature and refused. A legislature acting within constitutional limits is always free to make such a choice and have it prevail.23 Courts state the same limit among the requirements for the defense, asking whether the legislature has acted to preclude it by a clear and deliberate choice about the values at issue.24
The two versions differ only in whether the legislature actually confronted the claimed justification. In the first, silence leaves the defense to be decided on its remaining elements, beginning with the comparison of harms. In the second, the legislature's own refusal decides the case, which is why courts treat the question as one about what the legislature did and answer it by reading the enactment, not by balancing the harms themselves.
The most common error is to read clause (c) as though a stern prohibition were itself an exclusion. The severity of a penalty shows that the legislature takes the offense seriously, which every legislature does for every offense, and it shows nothing about whether the legislature considered and rejected a justification.
Clauses (b) and (c) describe different legislative acts. Under (b) the legislature has written its own narrower answer, an exception or defense with defined conditions, and the defendant is measured against it. Under (c) the legislature has said no to the justification itself, and the only question is whether it said so plainly. With the legislature's role settled, the next section turns to the actor's own conduct, because a defendant who clears both clauses can still lose the defense through fault in creating the emergency or in judging whether the conduct was necessary.
