interpretation judicial-review legislative-intent
What happens if a law contains an error of fact?
<p>If a law is passed that contains a demonstrably false statement or assumption about the world, how is it generally interpreted?</p>
<p>For example, laws will often list a category of things, and then give examples of specific things in the category. It is easy for some of the examples not to be true members of the category. You might have a law that says &quot;Only fish, such as pike, capybara, and perch, may be eaten on Fridays; animal meat is right out.&quot;</p>
<p>Does that make the capybara legally a &quot;fish&quot; for the purpose of that particular law? How would that affect courts trying to make determinations about what other things not specifically enumerated are (legal) fish?</p>
<p>Would an attorney be able to get any mileage out of the argument that the capybara is not in fact a fish, as noted by leading fish experts?</p>
<p>Can a law or part of a law be struck down not for being <em>wrong</em> but just for being <em>false</em>?</p>

<p><a href="https://supreme.justia.com/cases/federal/us/149/304/" rel="nofollow noreferrer">Nix v. Hedden</a>, 149 U.S. 304 (1893) is a famous &quot;error of fact&quot; case in the US. The situation was that there was an import tariff imposed on &quot;vegetables in their natural state&quot; brought in from outside the US, but not on &quot;Fruits, green, ripe, or dried, not specially enumerated or provided for in this act&quot; which were on a &quot;free&quot; list. Since imported tomatoes were taxed, it was said that tomatoes are fruits and not vegetables. The court ruled that <em>for legal purposes</em> the terms &quot;vegetable&quot; and &quot;fruit&quot; have their ordinary meaning, and are not held to a possibly variable scientific definition.</p>
<p>Definitions were read from Webster's Dictionary, Worcester's Dictionary and the Imperial Dictionary, and witnesses with decades of experience in the produce trade were called who testified as to whether the words had &quot;any special meaning in trade or commerce, different from those read&quot;. Dictionary entries were read regarding the definition of the words pea, eggplant, cucumber, squash, pepper, potato, turnip, parsnip, cauliflower and so on.</p>
<p>The court reasoned as follows based on the evidence. First,</p>
<blockquote>
<p>The passages cited from the dictionaries define the word ‘fruit’ as
the seed of plaints, or that part of plaints which contains the seed,
and especially the juicy, pulpy products of certain plants, covering
and containing the seed. These definitions have no tendency to show
that tomatoes are ‘fruit,’ as distinguished from ‘vegetables,’ in
common speech, or within the meaning of the tariff act</p>
</blockquote>
<p>and since the terms do not have a special meaning in trade or commerce, they must receive their ordinary meaning. Observe that &quot;scientific definition&quot; is not even a contender in this discussion. The court observed that &quot;dictionaries are admitted, not as evidence, but only as aids to the memory and understanding of the court&quot;.</p>
<p>The crux of the ruling is the following observation:</p>
<blockquote>
<p>Botanically speaking, tomatoes are the fruit of a vine, just as are
cucumbers, squashes, beans, and peas. But in the common language of
the people, whether sellers or consumers of provisions, all these are
vegetables which are grown in kitchen gardens, and which, whether
eaten cooked or raw, are, like potatoes, carrots, parsnips, turnips,
beets, cauliflower, cabbage, celery, and lettuce, usually served at
dinner in, with, or after the soup, fish, or meats which constitute
the principal part of the repast, and not, like fruits generally, as
dessert.</p>
</blockquote>
<p>In other words, specialized scientific definitions are not assumed to underlie the use of words selected by lawmakers. If lawmakers list &quot;fish, such as pike, capybara, and perch&quot;, then for purposes of that law and that law alone, capybara is defined to be a fish. Explicit redefinitions are fairly commonplace in writing laws, and lawmakers universally have the power to redefine words so that &quot;and means or and or means and, as necessary&quot;.</p>
<p>An example of a deliberate statutory redefinition is the fact that a bee is a fish in California, for some purposes, see <a href="https://www.courts.ca.gov/opinions/archive/C093542S.PDF" rel="nofollow noreferrer">Almond v. Fish</a>. In the Fish &amp; Game Code, <a href="https://leginfo.legislature.ca.gov/faces/codes_displayText.xhtml?lawCode=FGC&amp;division=0.5.&amp;title=&amp;part=&amp;chapter=1.&amp;article=" rel="nofollow noreferrer">FGC §45</a>,</p>
<blockquote>
<p>“Fish” means a wild fish, mollusk, crustacean, invertebrate,
amphibian, or part, spawn, or ovum of any of those animals</p>
</blockquote>
<p>which means that worms and jellyfish, and insects, are legal fish. The <a href="https://leginfo.legislature.ca.gov/faces/codes_displayText.xhtml?lawCode=FGC&amp;division=3.&amp;title=&amp;part=&amp;chapter=1.5.&amp;article=1." rel="nofollow noreferrer">Endangered Species Act</a> §2062 then says</p>
<blockquote>
<p>“Endangered species” means a native species or subspecies of a bird,
mammal, fish, amphibian, reptile, or plant which is in serious danger
of becoming extinct throughout all, or a significant portion, of its
range due to one or more causes, including loss of habitat, change in
habitat, overexploitation, predation, competition, or disease.</p>
</blockquote>
<p>Notice that under an interpretation of the law that ignores the statutory redefinition in §45, invertebrates and a number of chordates would not be protected by law. The court notes that this was a deliberate action by the legislature in 1969, in that
enrolled bill reports in support of this modification included the argument that</p>
<blockquote>
<p>The expanded definition of fish will permit closer control and
monitoring of the harvest of species such as starfish, sea urchins,
sponges and worms, and the ... Commission will be authorized to make
regulations deemed necessary for proper protection and management of
these species</p>
</blockquote>

<p>When a statute presents a general category and says that category &quot;includes&quot; some specific examples, those specific examples are <em>deemed</em> to belong to that category for the purpose of the statute.</p>
<blockquote>
<p>Statutory definitions are also used to expand the usual scope of <strong>a word or expression</strong>, for example:</p>
<blockquote>
<p>In this section,</p>
<p>&quot;fish&quot; includes shell fish, crustaceans, and marine mammals;</p>
</blockquote>
<p>...</p>
<p>In these examples, the statutory definition enlarges the ordinary (or technical) meaning of the defined terms by including things that might normally be thought to fall outside their denotation.</p>
<p>(Ruth Sullivan, <em>Statutory Interpretation</em>, 3rd ed. (2016), p. 81)</p>
</blockquote>
<p>And in the U.S. textualist context:</p>
<blockquote>
<p>Individual statutes often contain definition sections giving ordinary words a limited or artificial meaning.</p>
<p>(Antonin Scalia &amp; Bryan A. Garner, <em>Reading Law: The Interpretation of Legal Texts</em>)</p>
</blockquote>
<p>But Ruth Sullivan notes, &quot;statutory definitions do not necessarily lighten the interpreter's load. Many simply add to the ordinary or technical meaning of the defined term, which must still be determined in the usual way&quot; (p. 82).</p>
<p>There are many other competing canons and principles of interpretation. The fact that an unexpected example is listed may be read to imply that the general category is actually broader than its common meaning would normally convey. <strong>One cannot answer interpretation questions in the abstract</strong>. In <a href="/questions/tagged/canada" class="post-tag" title="show questions tagged &#39;canada&#39;" aria-label="show questions tagged &#39;canada&#39;" rel="tag" aria-labelledby="tag-canada-tooltip-container">canada</a>, the current approach to statutory interpretation is that:</p>
<blockquote>
<p>Today there is only one principle or approach, namely, the words of an Act are to be read in their entire context and in their grammatical and ordinary sense harmoniously with the scheme of the Act, the object of the Act, and the intention of Parliament.</p>
<p><em>Rizzo &amp; Rizzo Shoes Ltd. (Re)</em>, [1998] 1 S.C.R. 27 at <a href="https://canlii.ca/t/1fqwt#par21" rel="noreferrer">para. 21</a></p>
</blockquote>
<p>This approach has not been as universally accepted in the U.S., but given the inherent tensions between various <a href="https://en.wikipedia.org/wiki/Statutory_interpretation#Canons" rel="noreferrer">canons of interpretation</a> (same word–same meaning; <em>expressio unius</em>; etc.), it is similarly not possible to answer interpretive questions in the abstract. In all but the clearest cases (and even these would only be clear in context), to make any meaningful argument, one would need at least the full statute for examination.</p>

<blockquote>
<p>Does that make the capybara legally a &quot;fish&quot; for the purpose of that
particular law?</p>
</blockquote>
<p>Yes.</p>
<blockquote>
<p>How would that affect courts trying to make determinations about what
other things not specifically enumerated are (legal) fish?</p>
</blockquote>
<p>They would do their best to find a general principle. You see something similar in the efforts of Jewish legal scholars trying to apply Biblical Kosher food requirements to situations not described in the Hebrew Bible with <a href="https://www.chabad.org/library/article_cdo/aid/113425/jewish/What-Is-Kosher.htm" rel="nofollow noreferrer">Talmudic arguments</a>.</p>
<p>In Catholic Canon law (from which this particular example is drawn), which presents the same fish on Friday conundrum, they have a somewhat easier task, because the Pope is someone who has the capacity to resolve such questions in an absolutely authoritative manner even without coming up for a consensus reason for the distinction. Historically, <a href="https://www.mentalfloss.com/posts/lent-beavers-muskrats-capybaras-fish" rel="nofollow noreferrer">what happened was</a> this:</p>
<blockquote>
<p>During Lent, many Catholics deny themselves earthly pleasures to honor
Jesus's sacrifice. Abstaining from meat has nothing to do with animal
rights; instead, it's supposed to be a break from an ingredient
traditionally viewed as indulgent and luxurious. That's why beef,
pork, and poultry are considered meat but fish isn't. Fish was thought
of as a &quot;simple&quot; source of protein in the Middle Ages, whereas meat
from land animals was considered rich and therefore more &quot;sinful.&quot;</p>
<p>As is the case with the laws of most religions, Catholics have found
creative ways around this rule over the centuries. Between the 16th
and 18th centuries, a clergyman in Venezuela wrote to the Vatican
asking if it was alright to eat capybaras during times of fasting. The
South American rodents (the largest on Earth) are certainly not fish,
but because they spend a lot of time swimming, the church decided to
classify them as such. The Vatican has also made exceptions for other
semi-aquatic mammals like beavers and muskrats. Reptiles that live in
water, like turtles and alligators, qualify as fish during Lent as
well.</p>
</blockquote>
<p>In general, it is always possible to devise a rule that includes all outlier terms in a list, although in some cases that rule will be more contrived than in others.</p>
<p>For an example from non-religious law, the term &quot;commodities&quot; in which trading in future is regulated by the independent government agency known as the Commodity Futures Trading Commission (based in Chicago), includes all agricultural crops except onions. This is due to the <a href="https://en.wikipedia.org/wiki/Onion_Futures_Act" rel="nofollow noreferrer">Onion Futures Act of 1958</a> which was passed because there was a notorious incident in 1955 in which someone committed a massive market manipulation with the onion futures market that did massive harm to everyday people in the U.S. economy, even though, in principle, there is no good reason to regulate onion futures any differently from, for example, potato futures.</p>
<p>Similarly, even if two bottles of wine have contents that are chemically indistinguishable from each other (a client of mine is actually in the business of making exact chemical replicas of high priced wines using mass spectrometry and similar precision chemical tests) <a href="https://michaelfatelaw.com/articles/californias-wine-labeling-laws/" rel="nofollow noreferrer">under U.S. law</a>:</p>
<blockquote>
<p>To be designated as a “California” wine, 100% of the grapes used in
the wine must be grown in that state. To bear a viticultural area
designation such as “Napa,” “Sonoma,” or “El Dorado County,” 85% or
more of the grapes used must be grown in the designated area.</p>
</blockquote>
<p>So, it makes a factual distinction that doesn't really exist in a meaningful way from the perspective of a wine consumer.</p>
<blockquote>
<p>Would an attorney be able to get any mileage out of the argument that
the capybara is not in fact a fish, as noted by leading fish experts?</p>
</blockquote>
<p>No.</p>
<p>The best the attorney could hope for would be that there is also a capybara fish which is not as well known as the capybara mammal. If that were the case, the attorney could argue that the reference was to the capybara fish and not to the capybara mammal. But, if that isn't the case, the attorney has no leg to stand on legally. And, if there is an argument like that to be made, the legislative history of a law or regulation, regulations interpreting a statute shortly after it was adopted, or long standing practice in interpreting a law since its inception that is never authoritatively included in an authoritative legal document, could clearly rule out that interpretation.</p>
<blockquote>
<p>Can a law or part of a law be struck down not for being wrong but just
for being false?</p>
</blockquote>
<p>Not really.</p>
<p>In very rare instances, when the plain meaning of a law is absurd to the point of undermining the intent of the law expressed in other contexts the courts will interpret &quot;and&quot; to mean &quot;or&quot;, or &quot;shall&quot; to mean &quot;may&quot;, or &quot;do X&quot; to mean &quot;don't do X&quot; and will interpret it contrary to the plain reading on the grounds that it was a mere drafting error in the law. But this authority is virtually never used to invalidate a legal finding of fact.</p>
<p>Indeed, sometimes the law compels us to ignore certain facts.</p>
<p>For example, even if a parole eligibility model that included race as a factor was more accurate in predicting recidivism while on parole than the best available model that doesn't consider that factor, a parole eligibility model that considers race as a factor would be invalid as a matter of law.</p>
<p>Similarly, even if it is factually true that someone was in possession of illegal drugs, juries in a criminal prosecution for possession of those illegal drugs cannot consider that undisputedly true factual evidence if it was obtained in violation of the 4th Amendment.</p>
<p>The case of &quot;fish&quot; for the purpose of a particular law is much easier than that, however, because definitions can't be false by definition. There is no absolutely and universally true definition of any word. Instead, legal terms usually have multiple similar but not identical meanings.</p>
<p>The situation where a word has multiple meanings is called in linguistics and legal theory: <strong>polysemy</strong>.</p>
<blockquote>
<p>Polysemy—the existence of multiple related meanings for the same word
or phrase—is a frequent phenomenon in legal and lay language. Although
polysemy sometimes arises by accident, it also can be strategic:
framers of legal rules can advance private and public interests by
assigning meanings to terms that are different from—though connected
to—the meanings that those terms carry outside the law. Understanding
the functions of polysemy can help us design more effective legal
rules and can shed light on ways in which legal actors translate
language into power.</p>

</ul>
<p>Even if you are trying to conform to some meaningful and consistent concept in defining a legal term in a particular way, you can't really choose the correct definition until you know what the definition is seeking to distinguish from things outside the definition, i.e. the purpose of the law.</p>
<p>Definitions that don't match the most common sense of word in plain language are common in both legal statute and regulation drafting, and in contractual drafting.</p>

<p>Yes.</p>
<hr />
<p>I actually just dealt with this issue on the municipal level. A project of mine was before the Planning Board proposing an objectionable vice use. Pursuant to the zoning conditions, such a use could not be situated within 1,000 feet of a public park.</p>
<p>Because of the proposed vice use there was some public outcry on the matter. In an effort to kill the project, members of the public focused upon a publicly accessible walking trail immediately behind the site which the general public perceived as being a public park. After all, it was a public walkway with various amenities to facilitate the public's use of the space for biking and walking. Testimony was provided by the public that police periodically patrol for loitering. From the perception of the general public, it was a park.</p>
<p>Unfortunately, the zoning ordinance lacked a definition for 'public park', so the matter was referred to the Zoning Board for an official interpretation and it was deemed to not be a public park for the following reasons:</p>
<ul>
<li>The walking trail itself isn't actually public property, it's a private utility's right-of-way with an easement to permit the walking trail.</li>
<li>The zoning ordinance does have a definition for right-of-ways which was likely initially crafted imagining public roads in mind, but regardless is applicable for this site.</li>
<li>For the proposed use, the Township's Council needed to issue a letter approving the use at the specific location in order for a license to be issued <em>prior</em> to the Planning Board hearing (which the Council did). Given the conditional use requirements were set prior to the issuance of the letter, presumably, the Council did not perceive the walking trail as being a public park by virtue of them issuing the letter.</li>
</ul>
<p>Ultimately, the project was approved, against the wishes of some members of the public who insist that the trail is a public park. Regardless, their perception of it being a park is irrelevant for the purposes of what it is legally defined as.</p>
