Judicial Philosophy and Originalism

Textualism in statutory cases

Barrett emphasizes applying the text of statutes and the Constitution as written, a method aligned with textualism. She often asks what ordinary meaning a reasonable reader would attach to the words at the time of enactment.

Original public meaning in constitutional interpretation

In constitutional matters, she commonly interprets terms based on their original public meaning at ratification, arguing that judges should enforce the law rather than update it. This shapes her approach to issues such as separation of powers and individual rights.

Key Jurisprudence and Major Opinions

In California v. Texas (2021), Barrett joined the majority that rejected a broad challenge to the Affordable Care Act but also limited the scope of federal tax penalties. Her reasoning reflected a focus on statutory structure and the severability of provisions.

Barrett has written opinions cautioning against expansive readings of agency authority without clear congressional authorization. She underscores that agencies must act within the bounds of statutes and procedures established by Congress.

Her decisions on criminal procedure often highlight rules of evidence and the statutory framework governing sentencing, balancing judicial discretion with legislative directives in federal cases.
