The constitution organizes the government, and assigns to different departments their respective powers. It may either stop here; or establish certain limits not to be transcended by those departments. The government of the United States is of the latter description. The powers of the legislature are defined and limited; and that those limits may not be mistaken or forgotten, the constitution is written. To what purpose are powers limited, and to what purpose is that limitation committed to writing; if these limits may, at any time, be passed by those intended to be restrained?
Chief Justice John Marshall, in Marbury v. Madison
Originalism, broadly speaking, is that theory of justice which holds that the intention of the writers of the law is the key to its interpretation; and that, as laws were written to be read, it’s not some obscure mindreading process but rather “what those words would mean in the mouth of a normal speaker of English, using them in the circumstances in which they were used.” (Justice O. W. Holmes)
This is the doctrine of interpretation used by Justices Thomas, Kavanaugh, and Gorsuch, and to which they habitually adhere in almost all of their legal opinions. As they represent that portion of the Court which may possibly be swayed by legal argument, it is with respect to their interpretation that any statutory or argumentary replacement for Roe v. Wade ought practicably be drafted.
