Change detention in law from may to shall

What the document says

“Congress should eliminate ambiguous discretionary language in Title 8 that aliens “may” be detained and clarify that aliens “shall” be detained.”

Mandate for Leadership: The Conservative Promise, p. 150

The chapter says the word may creates ambiguity that lets the executive branch ignore the will of Congress, and asks for it to be replaced with shall so that detention is mandatory rather than discretionary.

What the document actually says

“Congress should eliminate ambiguous discretionary language in Title 8 that aliens “may” be detained and clarify that aliens “shall” be detained.”

That sentence, in plain words

The law says people may be held. The book says change it to must be held.

What this is about

One word in the law matters here. It says people may be held. That leaves a choice. The book says it should say must.

Securing Our Borders

2025-01-20 · 90 FR 8467

Section 5 directs the Secretary of Homeland Security to detain, to the fullest extent permitted by law, aliens apprehended for immigration violations until their removal, and to issue policy guidance or propose regulations on consistent use of detention authority under the Immigration and Nationality Act, including terminating the practice commonly known as catch and release. Section 2(c) states the same as policy. The result sought is the same as the passage seeks, but by the route the passage identifies as the problem: the direction operates inside existing discretion, is expressly bounded by what the law permits, and amends no statute, so the discretionary language the passage wants replaced remains and a later Secretary could read it differently.

In plain English

The order tells the Homeland head to hold aliens caught for immigration breaches until they leave, as far as the law allows. It ends the practice known as catch and release. The end sought is the same as the book's. But it works inside the same loose wording the book wants changed. No law is amended, so a later head could read it another way.

Partly matches

To require the Secretary of Homeland Security to take into custody aliens who have been charged in the United States with theft, and for other purposes

2025-01-29 · 139 Stat. 3

Section 2 adds a new subparagraph (E) to section 236(c)(1) of the Immigration and Nationality Act, the list of aliens who must be taken into custody, covering those inadmissible under section 212(a)(6)(A), (6)(C) or (7) who are charged with, arrested for, convicted of or admit burglary, theft, larceny, shoplifting, assault of a law enforcement officer, or a crime resulting in death or serious bodily injury, and provides that the Secretary of Homeland Security shall issue a detainer and take custody. Section 3 strikes the words or release from section 236(e). Congress is replacing discretion with a duty, by statute, which is the instrument and the direction the passage names. It is one added class rather than the general change described: the discretionary language of section 236(a) stands, and the rest of Title 8 is untouched.

In plain English

The law adds one group that must be held, not merely may be held. It covers people charged with theft, burglary, or badly hurting someone. Congress made this a duty, as the chapter wanted. But the rest of the law still leaves most cases to choice.

What cites those orders

3 agency rules

Each of these names the order above in its own summary, preamble or filing. That is a fact about the document, not a finding that it carries out this proposal: it is one step further away than the order is, and what it does about the proposal is a reading nobody has made here.

How to Read This Page

The quotation is the document's own words, exactly as printed, checked against the page number against the book itself before publishing. The paragraph underneath is our summary, not the document's words. So is the plain English version, which is why it sits beside the quotation rather than replacing it.
