The Dormant Commerce Clause, or Negative Commerce Clause, in American constitutional law, is a legal doctrine that courts in the United States have inferred from the Commerce Clause in Article I of the US Constitution. The primary focus of the doctrine is barring state protectionism. The Dormant Commerce Clause is used to prohibit state legislation that discriminates against, or unduly burdens, interstate or international commerce. Courts first determine whether a state regulation discriminates on its face against interstate commerce or whether it has the purpose or effect of discriminating against interstate commerce. If the statute is discriminatory, the state has the burden to justify both the local benefits flowing from the statute and to show the state has no other means of advancing the legitimate local purpose.

Filled milk is any milk, cream, or skim milk that has been reconstituted with fats, usually vegetable oils, from sources other than dairy cows. Pure evaporated filled milk is generally considered unsuitable for drinking because of its particular flavor, but is equivalent to unadulterated evaporated milk for baking and cooking purposes. Other filled milk products with substituted fat are used to make ice cream, sour cream, whipping cream, and half-and-half substitutes among other dairy products. Coconut oil filled milk became a popular cost-saving product sold throughout the United States in the early 20th century. Coconut oil could be cheaply imported, primarily from the Philippines, and this product was able to undercut the market for evaporated and condensed milk. At the time, liquid milk was not widely available or very popular in cities because of the rarity of refrigeration and the problems of transportation and storage.

The equal footing doctrine, also known as equality of the states, is the principle in United States constitutional law that all states admitted to the Union under the Constitution since 1789 enter on equal footing with the 13 states already in the Union at that time.

New States may be admitted by the Congress into this Union; but no new State shall be formed or erected within the Jurisdiction of any other State; nor any State be formed by the Junction of two or more States, or Parts of States, without the Consent of the Legislatures of the States concerned as well as of the Congress.
