How Vague Legal Standards Increase Government Power and Erode Constitutional Protections

Several states have argued that a provision in the American Rescue Plan is unconstitutionally vague because it prohibits states from using federal funds “directly or indirectly” to reduce taxes. The concern is that such language fails to provide a clear standard. If a law is vague, no one can reliably determine what conduct is permitted or prohibited, leaving enforcement entirely to the discretion of those in power. Vagueness allows authorities to interpret a statute in whatever manner suits their objectives, which is precisely what constitutional due‑process protections are designed to prevent.

A similar problem arose when California enacted the extremely vague “Best Interest of the Child” standard in family and juvenile dependency courts. The phrase lacks a precise legal definition and therefore grants judges extremely broad discretion. In practice, this has enabled significant unwarranted governmental interference (UGI) in family life. Judges have invoked the “Best Interest” standard to justify virtually any action, relying on its ambiguity to support decisions that may override parental rights without clear evidentiary thresholds.

The core issue in both contexts is the same: vague legal standards invite expansive governmental authority and reduce accountability. When a statute or standard lacks objective criteria, those charged with enforcing it can effectively decide what it means on a case‑by‑case basis. This undermines predictability, due process, and the constitutional protections individuals—especially parents—are entitled to expect.
