Reference excerpt

Missouri, Kansas, [sic] & Texas Railway Company of Texas v. Clay May, 194 U.S. 267 (1904), was a decision by the United States Supreme Court which held that a Texas law did not violate the Fourteenth Amendment to the United States Constitution by penalizing only railroad companies for allowing certain weeds to mature and go to seed on their land.

Overview Clay May, a Texas farmer who was not represented by counsel, obtained a penalty payment of US$25 from the Missouri, Kansas and Texas Railway of Texas (the Missouri, Kansas and Texas Railway's Texas subsidiary), also known as the "MKT", for having allowed Johnson grass to grow on its land. Under a 1901 Texas law, any railroad allowing Johnson grass or Russian thistle to mature and go to seed on their land would have to pay this penalty to owners of adjacent land, as long as those owners had not done the same thing. The MKT appealed and lost, and then appealed to the U.S. Supreme Court, arguing that the law violated the equal-treatment provisions of the Fourteenth Amendment, as it penalized only railroad companies and not other individuals or companies that allowed these weeds to grow.

Decision Justice Holmes, less than two years into his service on the Supreme Court, wrote for the Court's majority that a state law "should not be disturbed by the courts under the 14th Amendment, unless they can see clearly that there is no fair reason for the law that would not require ... its extension to others whom it leaves untouched." He wrote the Court felt "unable to say" whether the law was too arbitrary; that "it would have been more obviously fair" to also penalize highways; but offered several possible explanations for the Texas legislature's singling out of the railroads, and wrote that "legislatures are ultimate guardians of the liberties and welfare of the people in quite as great a degree as the courts." This latter line has been quoted numerous times in subsequent U.S. Supreme Court opinions, when the author of an opinion or dissent has deferred to a legislature. Although brief, Holmes's opinion has been said to have "displayed in miniature ... most of the features of his mature constitutional thought."

Dissent Justice Brown dissented, writing that the Texas law did not treat railroads differently because of the nature of a railroad, but pursued the railroad "merely as the proprietor of certain land alongside its track", which was excessively arbitrary under the Fourteenth Amendment, as other landowners were not penalized for the same offense.

Worked examples

Example 1 — a first encounter with Missouri, Kansas, & Texas Railway Co. of Texas v. May

Start with the simplest possible case. Write down what Missouri, Kansas, & Texas Railway Co. of Texas v. May claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Missouri, Kansas, & Texas Railway Co. of Texas v. May before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Missouri, Kansas, & Texas Railway Co. of Texas v. May ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Missouri, Kansas, & Texas Railway Co. of Texas v. May

In research
Missouri, Kansas, & Texas Railway Co. of Texas v. May appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Missouri, Kansas, & Texas Railway Co. of Texas v. May in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
