# DOJ Required to Use 'SI' Terminology for Artificial Intelligence Under New Trump Administration Directive

The Department of Justice has received orders to replace the term "artificial intelligence" with the acronym "SI" in official communications and filings, according to a directive linked to Trump administration policy preferences. The mandate creates immediate practical complications for federal prosecutors, civil litigants, and department officials who must now conform linguistic standards to terminology that diverges from industry, academic, and legal convention.

The order reflects a broader pattern of executive branch intervention in technical terminology. While the stated rationale remains unclear from available records, the directive forces DOJ personnel to adopt non-standard language across litigation, regulatory guidance, and internal memoranda. This departure from established nomenclature introduces potential ambiguity in legal documents where precision matters for judicial interpretation and precedent application.

The practical implications ripple across multiple legal domains. Federal prosecutors handling tech-related criminal cases must now frame charges and evidence summaries using "SI" rather than "AI." Civil litigants challenging algorithmic decision-making in hiring, lending, or benefits administration face inconsistency between the terminology used in court filings and the technical documentation they reference. Administrative agencies coordinating with DOJ on AI regulation and oversight must translate between their own established frameworks and this new departmental standard.

Legal professionals expressed concern about document clarity and judicial reception. Courts rely on consistent terminology for case law development and precedent citation. When federal prosecutors file briefs using non-standard language, judges reviewing those documents encounter an additional interpretive layer. Defense attorneys gain arguable grounds to challenge government filings on clarity grounds, potentially requiring remand or resubmission in standard language.

The directive also affects DOJ's regulatory and advisory functions. The department issues guidance to federal agencies on technology compliance, cybersecurity, and data protection. Mandatory use of "SI" terminology in this guidance creates friction with other agencies operating under their own technical standards. The Office of Management and Budget, National Institute of Standards and Technology, and Federal Trade Commission all maintain established AI terminology frameworks that diverge from this mandate.

Big Law firms representing clients in DOJ matters now face strategic questions about language conformity. Should external counsel adopt the DOJ's "SI" terminology in communications with the department to demonstrate alignment? Or should firms maintain standard industry language in client advice and external communications while code-switching for DOJ submissions? This creates drafting complexity and potential inconsistency within single litigation files.

The order raises First Amendment concerns regarding compelled government speech, though the DOJ's internal communication decisions typically fall outside constitutional constraint. However, the requirement that federal prosecutors use non-standard terminology in public court filings arguably burdens the government's own advocacy function by introducing unnecessary complexity.

The directive also signals a broader pattern of executive branch micromanagement of technical standards. If terminology mandates extend to other agencies, federal regulatory infrastructure could fragment along political rather than technical lines. Environmental agencies, financial regulators, and health authorities might receive similar orders to adopt idiosyncratic language that conflicts with scientific consensus and industry practice.

Compliance deadlines remain uncertain. The DOJ has not published explicit enforcement mechanisms or timelines for full departmental adoption. Some offices may implement the change immediately while others lag, creating internal inconsistency and confusion among federal attorneys working across multiple offices.
